Mechanical M8SL2-00-002-812 2 Mechanical 2.1 Torx Recess Head Screws A2.1 Torx recess head screws are becoming the standard screw head type in all T800 SL2 equipment, with Pozidriv and Philips recess head screws being used in fewer applications. The Torx recess head has the advantage of improved screwdriver tip location, reducing the chances of screw head damage caused by the driver tip rotating within the recess. In addition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw with the driver on a slight angle, which can be useful in situations where access is restricted. It is important that you use the correct Torx screwdriver tip: M3 screws M4 screws T10 T20 Figure 2.1 below shows a typical Torx recess head screw (actual hardware may differ slightly from this illustration due to variations in manufacturing techniques). "star” shaped recess with six internal notches Figure 2.1 Torx Screw Identification © Copyright Tait Electronics Limited August 2004. All rights reserved. A2.2 Mechanical 2.2 Pozidriv and Philips Recess Head Screws M8SL2-00-002-812 Pozidriv and Philips recess head screws will continue to be used in T800 SL2 equipment in a few special applications. It is important that you use the correct type and size screwdriver for each screw type to avoid damaging the screw head. It is particularly important that you do not use Philips screwdrivers on Pozidriv screw heads as the tapered driving flutes of the Philips screwdriver do not engage correctly with the parallel-sided slots in the Pozidriv screw head. This can result in considerable damage to the screw head if the screwdriver tip turns inside the recess. Note: If you find you need excessive downwards pressure to keep the screwdriver tip in the Pozidriv screw head, you are probably using the wrong type and/ or size screwdriver. Figure 2.2 below shows the main differences between typical Pozidriv and Philips screw heads and screwdriver tips (actual hardware may differ slightly from these illustrations due to variations in manufacturing techniques). Pozidriv Philips internal notches no special markings "star" markings between slots slots with parallel sides slots with tapered sides driving flutes with parallel sides driving flutes with tapered sides ridges between driving flutes Figure 2.2 Pozidriv and Philips Screw and Screwdriver Identification © Copyright Tait Electronics Limited August 2004.

M8SL2-00-002-812 Component Replacement 3 Component Replacement 3.1 Leaded Components A3.1 Whenever you are doing any work on the PCB that involves removing or fitting components, you must take care not to damage the copper tracks. The two satisfactory methods of removing components from plated-through hole (PTH) PCBs are detailed below. Note: The first method requires the use of a desoldering station, e.g. Philips SBC 314 or Pace MBT-100E. 3.1.1 Desoldering Iron Method Place the tip over the lead and, as the solder starts to melt, move the tip in a circular motion. Start the suction and continue the movement until 3 or 4 circles have been completed. Remove the tip while continuing suction to ensure that all solder is removed from the joint, then stop the suction. Before pulling the lead out, ensure it is not stuck to the plating. If the lead is still not free, resolder the joint and try again. Note: The desoldering iron does not usually have enough heat to desolder leads from the ground plane. Additional heat may be applied by holding a soldering iron on the tip of the desoldering iron (this may require some additional help). 3.1.2 Component Cutting Method Cut the leads on the component side of the PCB. Heat the solder joint sufficiently to allow easy removal of the lead by drawing it out from the component side: do not use undue force. Fill the hole with solder and then clear with solderwick. © Copyright Tait Electronics Limited August 2004. All rights reserved. A3.2 Component Replacement 3.2 Surface Mount Devices Caution: 3.3 M8SL2-00-002-812 Surface mount devices (SMDs) require special storage, handling, removal and replacement techniques. This equipment should be serviced only by an approved Tait Dealer or Customer Service Organisation equipped with the necessary facilities. Repairs attempted with incorrect equipment or by untrained personnel may result in permanent damage. If in doubt, contact your nearest Tait Dealer or Customer Service Organisation. Cased Mica Capacitors Cased mica capacitors can be removed by heating the top with a heavy-duty soldering iron and gently lifting the capacitor off the PCB with a solder-resistant spike or equivalent. © Copyright Tait Electronics Limited August 2004.

M8SL2-00-002-812 1.1 T855 General Information B1.5 Introduction The T855 is a high performance microprocessor controlled FM base station receiver designed for single or multichannel operation in the 400 to 530MHz frequency range1. The receiver is a dual conversion superhet with a synthesised local oscillator. The first IF is 45.0MHz, allowing exceptionally high spurious signal rejection to be achieved in the receiver front end. The second IF section (455kHz) combines amplitude limiting, detection and audio preamplification within a single integrated circuit. It also drives carrier and noise level detectors for signal strength indication and gating the audio output. RSSI can be used to drive a carrier mute for audio output gating (link selectable) when the optional T800-04-0000 RSSI PCB is fitted. The audio section output can be adjusted to deliver >+10dBm to a 600Ω balanced output, and 1W to a local monitor speaker. A flat or de-emphasised audio response is link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an additional D-range connector (D-range 2 – T800-03-0000) at the rear of the set. All components except those on the VCO board are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each section of circuitry. Access to both sides of the main PCB is obtained by removing each of the two chassis covers. There is provision within the chassis to mount small option PCBs. The front panel controls include gating sensitivity, line level, monitor volume and a monitor mute switch. 1. Although capable of operating over the 400 to 530MHz frequency range, the T855 has a 5MHz switching range (see Section 1.2.3 and Section 3.1). © Copyright Tait Electronics Limited August 2004.

This low loss filter (typically less than 0.5dB over 400 to 530MHz) provides excellent immunity to interference from high frequency signals. The signal is then further filtered, using a high performance helical resonator doublet (FL410) which provides exceptional image rejection, before being amplified by approximately 8dB (Q410). The signal is then passed through a further helical filter doublet (FL420) before being presented to the mixer via a 2dB attenuator pad. Each sub-block within the front end has been designed with 50Ω terminations for ease of testing and fault finding. The overall gain from the antenna socket to the mixer input is approximately 2dB. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 2.3 T855 Circuit Operation B2.5 Mixer (Refer to the front end circuit diagram (sheet 4) in Section 6.3 and Figure 2.2.) IC410 is a high level mixer requiring a local oscillator (LO) drive level of +17dBm (nominal). The voltage controlled oscillator (VCO) generates a level of +21dBm (typical) and this is fed to the mixer via a 5dB attenuator pad. A diplexer terminates the IF port of the mixer in a good 50Ω, thus preventing unnecessary intermodulation distortion. 2.4 IF Circuitry (Refer to the IF section circuit diagram (sheet 3) in Section 6.3 and Figure 2.2.) Losses in the mixer are made up for in a tuned, common gate, post mixer amplifier (Q310). Several stages of amplification and filtering are employed in the IF circuitry. The first crystal filter is a 4-pole device (&XF300) which is matched into 50Ω on both its input and output ports. This stage is followed by a common base amplifier (Q320) whose output is matched into a 2-pole crystal filter (&XF301). The signal is then amplified using a high gain MOSFET amplifier (Q350), after which the signal is mixed down to 455kHz with the second crystal local oscillator (44.5455MHz). The 455kHz signal is filtered using a 6-pole ceramic filter (&XF302) before being limited and detected. Q340 provides a buffered 455kHz output for use with the optional RF level detector (RSSI) The second IF mixer, limiter and detector is in a 16-pin IC (IC310). Quadrature detection is employed, using L390, and the recovered audio on pin 9 of IC310 is typically 1Vpp for 60% system deviation. © Copyright Tait Electronics Limited August 2004. All rights reserved. B2.6 T855 Circuit Operation 2.5 Noise Mute (Squelch) M8SL2-00-002-812 (Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respectively) in Section 6.3 and Figure 2.2.) The noise mute operates on the detected noise outside the audio bandwidth. An operational amplifier in IC310 is used as an active band pass filter centred on 70kHz to filter out audio components. The noise spectrum is then further amplified in a variable gain, two-stage amplifier (Q350 and Q360) with additional filtering. The noise is then rectified (D310) and filtered to produce a DC voltage proportional to the noise amplitude. The lowest average DC voltage corresponds to a high RF signal strength and the highest DC voltage corresponds to no signal at the RF input. The rectified noise voltage is compared with a threshold voltage set up on RV230, the front panel “Gating Sensitivity” potentiometer. Hysteresis is provided by the feedback resistor (R267) to prevent the received message from being chopped when the average noise voltage is close to the threshold. R281 and R280 determine the mute opening and closing times and, in combination with solder links SL210 and SL220, provide three time delay options (SL210 is linked as standard. Refer to Section 3.8). The mute control signal at pin 7 of IC270 is used to disable the speaker and line audio outputs. The speaker output can be separately enabled for test purposes by operating the front panel mute disable switch, SW201. 2.6 Carrier Mute (Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respectively) in Section 6.3 and Figure 2.2.) A high level carrier mute facility is also available. The RSSI (refer to Section 2.12) provides a DC voltage proportional to the signal strength. This voltage is compared with a preset level, set up on RV235, and may be linked into the mute timing circuit using PL250. PL250 selects either the noise mute or the carrier mute. From this point both the noise and carrier mute circuits operate in the same manner, using common circuitry. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Linking (PL220 and PL210) is available to give either a flat or de-emphasised audio response, with de-emphasis giving a –6dB/octave roll off. The output of IC210 is split to provide separate paths for the speaker and line outputs. The “Audio 1”, Audio 2” and “Speech” lines allow access to the receiver’s audio path for external signalling purposes (refer to Section 3.5). The signals are passed to audio drive amplifiers IC240 and IC260. Under muted conditions the inputs of these amplifiers are shunted to ground via transistors Q230 and Q290 respectively. The audio output of IC240 has a DC component which is removed by C249, and this then drives a speaker directly. The output of IC260 is fed into a line transformer to provide a balanced 2-wire or 4-wire, 600Ω output. The speaker volume is set using the front panel “Monitor Volume” knob (RV205) and the line level is set using the recessed “Line Level” potentiometer (RV210). The red front panel “Gate” LED (D250) indicates the status of the mute circuit. When a signal above the mute threshold is received, the LED is illuminated. The “Monitor” switch (SW201) on the front panel opens the mute, allowing continuous monitoring of the audio signal (on = audio unmuted; off = audio muted). The mute control line is available on pad 234 ("RX GATE OUT") for control of external circuitry. A high (9V) on pad 234 indicates that the audio is disabled and a low (0V) indicates that a signal above the mute threshold level is being received. © Copyright Tait Electronics Limited August 2004.

B2.8 T855 Circuit Operation M8SL2-00-002-812 The audio can also be disabled using the “RX-DISABLE” inputs, pads 225 or 228, having connected the “RX-DISABLE” link between pins 1 and 2 of PL260. An adjustable time delay (RV220) is provided on these lines. In order to disable the audio, either pad must be pulled to 0V. An undedicated relay is provided (RL210) for transmitter keying or other functions and this can be operated from the mute line by linking PL270. 2.8 Power Supply And Regulators (Refer to the regulators circuit diagram (sheet 6) in Section 6.3.) 13.8V Nom.

A 5.3V regulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser circuitry. It is also used as the reference for a DC amplifier (IC640, Q630 and Q620) which provides a medium current capability 9V supply. A switching power supply, based on Q670 and Q660, runs off the 9V supply and provides a low current capability +20V supply. This is used to drive the synthesiser loop filter (IC740), giving a VCO control voltage of up to 20V. The 13.8V supply drives both output audio amplifiers without additional regulation. A separate 5V regulator (IC610) drives the microprocessor and associated digital circuitry. The output of this regulator is monitored by the Low Voltage Interrupt (LVI) circuit (IC650). A crowbar diode is fitted for protection against connection to a power supply of incorrect polarity. It also provides transient overvoltage protection. Note: A fuse must be fitted in the power supply line for the diode to provide effective protection. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Four ports are available for input/output functions. Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM (IC820). This serial bus is also used by the microcontroller to program the synthesiser (IC740). The main tasks of the microcontroller are as follows: • program the synthesiser; • interface with the PGM800Win programming software at 9600 baud via the serial communication lines on D-range 1 (PL100) and D-range 2; • monitor channel change inputs from D-range 2; • generate timing waveforms for CTCSS detection; • coordinate and implement timing control of the receiver; • control the front panel “Supply” LED (refer to Section 5.3). © Copyright Tait Electronics Limited August 2004.

FREQUENCY SYNTHESISER IC Reference Divider 12.8MHz Reference Oscillator Serial Bus f ref Clk Data En Phase Detector VCO PCB Charge Pump Loop Filter VCO Buffer Output Buffer +22dBm L.O. /R Programmable Divider Prescaler /N 64/65 fin Buffer Controller Figure 2.6 T855 Synthesiser Block Diagram The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled oscillator (VCO) to a given reference frequency. The synthesiser receives the divider information from the control microprocessor via a 3-wire serial bus (clock, data, enable). When the data has been latched in, the synthesiser processes the incoming signals from the VCO buffer (fin) and the reference oscillator (fref). A reference oscillator at 12.8MHz (IC700) is buffered (IC710) and divided down to 6.25kHz or 5kHz within the synthesiser IC (IC740). A buffered output of the VCO is divided with a prescaler and programmable divider which is incorporated into the synthesiser chip (IC740). This signal is compared with the reference signal at the phase detector (also part of the synthesiser chip). The phase detector outputs drive a balanced charge pump circuit (Q760, Q770, Q775, Q780, Q785) and active loop filter (IC750, Q790) which produces a DC voltage between 0V and 20V to tune the VCO. This VCO control line is further filtered to attenuate noise and other spurious signals. Note that the VCO frequency increases with increasing control voltage. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 2.11 T855 Circuit Operation B2.11 VCO (Refer to the VCO circuit diagram in Part E.) The VCO transistor (Q1) operates in a common emitter, and uses a transmission line resonator (TL1). The transmission line is used in a two port configuration with varicaps positioned at one end. The VCO control voltage from the loop filter (IC750) is applied to the varicaps (D1 and D2) to facilitate tuning. The VCO output is coupled into a cascode amplifier stage (Q2 and Q3) which supplies +10dBm (nominal) output. Further amplification in Q5 brings the output drive level to +20dBm to drive the mixer. A low level “sniff” is taken from the input to Q5 to drive the divider buffer to the synthesiser (IC740). The VCO operates at the actual frequency required by the first mixer, i.e. there are no multiplier stages. The VCO frequency spans from 355 to 395MHz, 395 to 435MHz or 435 to 485MHz according to product type. The VCO is tuned to 45MHz below the desired receive frequency (low side injection) to produce a 45MHz IF signal at the output of the mixer. © Copyright Tait Electronics Limited August 2004. All rights reserved. B2.12 T855 Circuit Operation 2.12 Received Signal Strength Indicator (RSSI) M8SL2-00-002-812 (Refer to the T800-04-0000 RSSI PCB circuit diagram in Section 6.2 and the IF section circuit diagram (sheet 3) in Section 6.3.) The RSSI option PCB plugs directly into the main PCB (support circuitry being fitted as standard). It is fitted to the T855 whenever receiver signal strength monitoring is required, e.g. trunking or voting. Its function is to provide a DC voltage proportional to the signal level at the receiver input. The DC voltage is available at D-range 1 (PL100 pin 5). The RSSI also provides the capability for high level signal strength muting, which may be selected on PL250 (refer to Section 3.5). The mute threshold may be set between –115dBm and –70dBm by RV235. +V RSSI Input Amp Detector Q1C Q1A & Q1B Variable Gain Stage Q1E Error Amp VDC Temp Comp Temp Comp Q1D RSSI Output 1V/10dB DC Amp (Gain= x33) NTC DC Offset (Ref) Figure 2.7 T855 RSSI Block Diagram (T800-04-0000 RSSI PCB) The variable gain stage (Q1A) is a common emitter amplifier with its emitter grounded and the AGC control loop voltage applied to its base. Since the AGC loop will maintain a constant signal level at the collector, the gain of Q1 must be proportional to the incoming 455kHz signal level. The gain of Q1 is linearly proportional to its collector current which itself is exponentially related to the base-emitter voltage. Thus there is a logarithmic relationship between the base-emitter voltage and the gain. The circuit therefore produces a feedback voltage, and an output voltage, logarithmically related to the RF input signal. The AGC loop is followed by a DC amplifier which provides level shifting, temperature compensation and gain to give a nominal 1V/10dB at the RSSI output. RV320 on the main PCB is used to set the RSSI voltage to a fixed value at a given RF input signal strength. © Copyright Tait Electronics Limited August 2004. All rights reserved.

M8SL2-00-002-812 3.1 T855 Initial Tuning and Adjustment B3.3 Introduction When you receive your T855 receiver it will be run up and working on a particular frequency (the “default channel")1. If you want to switch to a frequency that is within the 5MHz switching range (i.e. ±2.5MHz from the factory programmed frequency), you should only need to reprogram the receiver with the PGM800Win software (refer to the PGM800Win programming kit and Section 3.2 below). However, if you want to switch to a frequency outside the 5MHz switching range, you will have to reprogram and re-tune the receiver to ensure correct operation. In this case you should carry out the short tuning procedure described in Section 3.4. If you have carried out repairs or other major adjustments, you must carry out the full tuning and adjustment procedure described in this section (except for Section 3.4). 3.2 Channel Programming You can program up to 128 channel frequencies into the receiver’s EEPROM memory (IC820) by using the PGM800Win software package and a PC. You can also use PGM800Win to select the receiver’s current operating frequency (or “default channel"). You can program the receiver via the programming port in the front panel. However, you can also program the receiver before it is installed in a rack frame as follows: • by using a T800-01-0010 calibration test unit; • via D-range 1; • via D-range 2 (standard T800-03-0000 auxiliary D-range only); • via SK805 (internal Micromatch connector). If you do not use the T800-01-0010, you will have to connect the PC to the receiver via a module programming interface (such as the T800-01-0004). For a full description of the channel programming procedure, refer to the PGM800Win programming software user’s manual. Note: When an auxiliary D-range kit (D-range 2 – T800-03-0000) is fitted, you can also select a channel with an external switch, such as the DIP switch on a backplane PCB. Consult your nearest Tait Dealer or Customer Service Organisation for further details. 1. Use the “Read Module” function in PGM800Win to find out what the default channel is. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Remove the top cover. Set up the test equipment as described in Section 3.3. Set the links in the audio processor section as required (refer to Section 3.5). 3.4.2 Synthesiser Alignment • Connect a high impedance voltmeter to the long lead of L1 in the VCO (this measures the synthesiser loop voltage). • Single Channel Tune VCO trimmer C6 for a synthesiser loop voltage of 10V. Multichannel Tune VCO trimmer C6 for a synthesiser loop voltage of 10V on the middle channel. If there is no middle channel, tune C6 so that the channels are symmetrically placed around a loop voltage of 10V. All channels should lie within the upper and lower limits of 16V and 3V respectively. Do not attempt to program channels with a greater frequency separation than the specified switching range of 5MHz. 3.4.3 Front End Alignment Note 1: In this and following sections deviation settings are given first for wide bandwidth sets, followed by settings in brackets for mid bandwidth sets ( ) and narrow bandwidth sets [ ]. Note 2: For multichannel operation align the receiver on a frequency in the middle of the required band. Set RV230 (front panel gating sensitivity) fully clockwise.

M8SL2-00-002-812 3.5.2 T855 Initial Tuning and Adjustment B3.9 Audio Processor Linking Details For CTCSS You must connect the audio processor links correctly according to the CTCSS option used, as shown in the table below. CTCSS Option PL230 PL240 standard, no CTCSS 2–3 N–P 2–3 H–J received CTCSS + speech passed to line output 3–4 P–Q 1–2 G–H high pass filtered speech, internal CTCSS detection 2–3 N–P 4–5 K–L external CTCSS detection 1–2 M–N 4–5 K–L The conditions stated in the above table are defined as follows: • standard, no CTCSS – no CTCSS or other sub-audio signalling used – audio bandwidth 300Hz to 3kHz – hum and noise –55dB • received CTCSS tone + speech to line output – tone and speech transmitted down 600Ω line – audio bandwidth 10Hz to 3kHz – hum and noise –45dB • high pass filtered speech – 400Hz to 3kHz + internal CTCSS detection – hum and noise –30dB with 250.3Hz tone present • external CTCSS detection – decoding performed through the receiver (but externally) – speech injected back into receiver via “AUDIO-2" and sent down 600Ω line Note 1: AUDIO-2 is available on D-range 1 (PL100) pin 7 via the link resistor R160. Although PL100 pin 7 is already assigned to SERIAL-COM, this can be disabled by removing R808. Note 2: External CTCSS units can connect in series with the audio chain via AUDIO-1 and AUDIO-2. © Copyright Tait Electronics Limited August 2004. All rights reserved. B3.10 T855 Initial Tuning and Adjustment 3.6 Synthesiser Alignment M8SL2-00-002-812 • Ensure that the receiver has been programmed with the required frequencies using the PGM800Win software. • Connect a high impedance voltmeter to the long lead of L1 in the VCO (this measures the synthesiser loop voltage). • Single Channel Tune VCO trimmer C6 for a synthesiser loop voltage of 10V. Multichannel Tune VCO trimmer C6 for a synthesiser loop voltage of 10V on the middle channel. If there is no middle channel, tune C6 so that the channels are symmetrically placed around a loop voltage of 10V. All channels should lie within the upper and lower limits of 16V and 3V respectively. Do not attempt to programme channels with a greater frequency separation than the specified switching range of 5MHz. • The TCXO =(IC700) output frequency should be trimmed when the IF is tuned. Refer to Section 3.7. 3.7 Alignment Of Receiver Front End And IF Note: In this and following sections deviation settings are given first for wide bandwidth sets, followed by settings in brackets for mid bandwidth sets ( ) and narrow bandwidth sets [ ]. Align the synthesiser as instructed in Section 3.6. For multichannel operation align the receiver on a frequency in the middle of the required band. Set RV230 (front panel gating sensitivity) fully clockwise. Inject a strong on-channel RF signal with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz into the antenna socket and adjust the helicals (#FL410 and #FL420) to give the best sinad. Continually decrease the RF level to maintain 12dB sinad. Roughly tune IF coils L310, L320, L330, L340, L350, L360, L370, L380, L385 and L390 for best sinad. While maintaining a low level unmodulated RF input to the receiver, loosely couple into the first IF an additional high level signal at 45MHz, you will hear a beat note. Trim the synthesiser TCXO (=IC710) for zero beat. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 T855 Initial Tuning and Adjustment B3.11 While maintaining the low level RF input to the receiver, loosely couple into the second IF an additional high level signal at 455kHz, you will hear a beat note. Tune L385 for zero beat. Note: If a second oscillator is not available, you can connect a frequency counter to IC710 pin 8 (i.e. after the TCXO buffer) via an oscilloscope probe to measure the TCXO frequency directly (12.8MHz). At this point the voltage level is approximately 4Vpp. Readjust the front end helicals (#FL410 and #FL420) to give the best sinad. Change the RF signal level to –75dBm and modulate with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz. Connect an oscilloscope probe to SK320 pin 3 (RSSI 455kHz input) and connect plugs PL210 and PL220 to give a flat audio response (refer to Section 3.5). Readjust L310, L320, L330, L340, L350, L360, L370 and L380 to give a maximum amplitude response on the oscilloscope with minimal amplitude modulation. Note: If you would like a more accurate method of tuning the IF, refer to the sweep tuning method described in Section 5.5.5. Further adjust these coils, along with L390, for minimum audio distortion, ensuring that the 455kHz level (on the oscilloscope) does not fall significantly. Check that the distortion reading is: wide bandwidth mid and narrow bandwidth ≤2% ≤4%. If required, reconnect plugs PL210 and PL220 to give a de-emphasised audio response and check that the distortion reading is ≤2% (all bandwidths). Reduce the RF level until 12dB sinad is reached. The receiver sensitivity should be better than –117dBm (de-emphasised) or –111dBm (flat), assuming that the audio levels are not being overdriven (refer to Section 3.11). © Copyright Tait Electronics Limited August 2004.

Rotate RV230 (front panel gating sensitivity) anticlockwise until the “Gate” LED is extinguished. Set switch SW201 (front panel monitor mute) to the on position. Check that the current in the 13.8V power cable is less than 350mA. Rotate the RV230 clockwise until the “Gate” LED is lit. Rotate RV210 (front panel line level) and RV205 (front panel monitor volume) to give maximum outputs. Check that the current is less than 800mA. Reset the front panel controls to the required settings. 4.2 Sensitivity If CTCSS is enabled, disable the CTCSS tone by either programming the T855 for “No Tone” on the set channel, or by pulling pin 10 of D-range 2 (CTCSS ENABLE) low. Apply an on-channel signal from the RF generator with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz. Adjust the RF level to give 12dB audio sinad. Check that the sensitivity is –117dBm or better. 4.3 Switching Range Apply an on-channel signal from the RF generator at various frequencies within the 5MHz switching range (front end bandwidth), corresponding to pre-programmed channels.

Check that the distortion is approximately 1% THD. Note: For a flat response, the distortion should always be better than 2% for wide bandwidth sets or 4% for mid and narrow bandwidth sets. Adjust RV205 (front panel monitor volume) to give 2Vrms into a 4Ω resistive load. Check that the distortion at the monitor output is better than 2% THD. Reset the controls before proceeding to the next set of tests. 4.5 Ultimate Signal-To-Noise Ratio Apply a signal from the RF generator at a level of –57dBm with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz. Select de-emphasis on the links provided in the audio processor (refer to Section 3.5), and link pins 2 and 3 of PL240 to include the 300Hz filter. Adjust RV210 (front panel line level) to provide +10dBm output. Switch off the modulation, checking that the residual noise is lower than –45dBm (–43dBm) [–39dBm] at the line output (this corresponds to S/N of 55dB (53dB) [49dB] and is in accordance with EIA measurement conditions).

T855 Fault Finding M8SL2-00-002-812 5.1 B5.3 Visual Checks Remove the covers from the T855 and inspect the PCB for damaged or broken components, paying particular attention to the surface mounted devices (SMDs). Check for defective solder joints. If repair or replacement of components is considered necessary, refer to Section 3 of Part A. 5.2 Component Checks If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, first make sure that the transistor is not shunted by some circuit resistance. Use a good quality EVM (e.g. Fluke 75) for taking the measurements (or a 20kΩ/V or better multimeter, using only the medium or low resistance ranges). The collector current drawn by multi-junction transistors is a further guide to their performance. If an IC is suspect, the most reliable check is to measure the DC operating voltages. Due to the catastrophic nature of most IC failures, the pin voltages will usually be markedly different from the recommended values in the presence of a fault. The recommended values can be obtained from either the circuit diagram or the component data catalogue. 5.3 Front Panel LED Indicator The green “Supply” LED on the front panel will flash according to the conditions described in the following table: Flash Rate Condition fast (1s on/1s off approx.) receiver is linked with PGM800Win slow (1s on/1s off approx.) VCO is out of lock – refer to Section 5.4.2 unequal (1s on/1s off approx.) microcontroller has detected an internal communications error – refer to Section 5.7.1 Where two or more conditions occur at the same time, the precedence is in the order shown above (i.e. receiver linked has the highest priority, followed by VCO error, then internal error). © Copyright Tait Electronics Limited August 2004.

B5.4 T855 Fault Finding 5.4 DC Checks 5.4.1 Power Rails M8SL2-00-002-812 Refer to the test points and options diagrams in Section 6 for test point locations, and to the regulator fault finding chart (Section 5.7.2) for fault diagnosis. Check the 9V (TP602) and 13.8V (TP601) power supply test points in the regulator compartment with a DMM. Check the 20V regulator output at the test point (TP603) in the regulator compartment. Check the 5V regulator output at the test point (TP604) in the regulator compartment and on IC310 pin 4. Check the 5V digital regulator output at the junction of C611A (+) and IC610 pin 2 in the regulator compartment. 5.4.2 VCO Locking Using a DMM, monitor the VCO control voltage on the long lead of L1 on the VCO PCB. If the synthesiser is locked and the VCO aligned, the voltage at this point should be between 3 and 16V. If the VCO is not locked, refer to the synthesiser fault finding charts (Section 5.7.3). 5.4.3 Mute Operation The front panel “Gate” LED will show the status of the mute circuitry and will turn on when a signal is received above the threshold level. Check that PL250 is linked correctly: noise mute carrier mute 1–2 2–3. Check that the mute gate opens as follows: noise mute rotate RV230 (front panel gating sensitivity) fully clockwise and check that the front panel “Gate” LED turns on; carrier mute rotate RV235 (carrier mute) fully clockwise and check that the front panel “Gate” LED turns on. If the mute fails to operate correctly, refer to the noise mute fault finding chart (Section 5.7.4) or the carrier mute fault finding chart (Section 5.7.5). © Copyright Tait Electronics Limited August 2004. All rights reserved. T855 Fault Finding M8SL2-00-002-812 5.5 RF Checks 5.5.1 VCO Frequency B5.5 Check that the VCO is phase locked (refer to Section 5.4.2). Connect a frequency counter (level +20dBm) to the VCO input to the mixer (IC410). Monitor the local oscillator frequency and check that it is 45MHz below the required receive frequency. Refer to the synthesiser fault finding charts (Section 5.7.3) for further information. 5.5.2 RF Sensitivity Ensure that the VCO is on the correct frequency and the receiver correctly aligned. Check that the 12dB sinad sensitivity into the front end is as follows: –117dBm (de-emphasised response) –111dBm (flat response). If the sensitivity is poor, you can trace the fault by measuring the sensitivity into successive circuit blocks. Prepare a test cable by connecting a 1nF capacitor to the end of a length of coax cable as shown in Figure 5.1. 1nF To Test Cable Coax Connect To Earth Figure 5.1 RF Test Cable Note: Before using the test cable, ensure the coax braid is connected to an earth point on the PCB. Using the RF test cable, apply a modulated 45MHz signal to the test breaks in the IF section, or an on-channel RF signal to the front end test breaks. Check that the sensitivity at each test break is within 2dB of the levels shown on the circuit diagram. Poor sensitivity indicates a fault in one of the circuit blocks following the test break. Note: Poor sensitivity into the mixer can be caused by lack of drive level from the VCO (the drive level should be >+17dBm). Refer to the receiver fault finding charts (Section 5.7.6) for further information. © Copyright Tait Electronics Limited August 2004. All rights reserved. B5.6 T855 Fault Finding 5.5.3 Oscillator Stability 5.5.3.1 TCXO M8SL2-00-002-812 While maintaining a low level unmodulated RF input to the receiver, loosely couple into the first IF an additional high level signal at 45MHz. You should now hear a constant low frequency beat note. Tap the TCXO with a finger and replace it if the beat note permanently changes. 5.5.3.2 Second IF While maintaining a low level unmodulated RF input to the receiver, loosely couple into the second IF an additional high level signal at 455kHz. You should now hear a constant low frequency beat note. Adjust L385 for “zero beat". 5.5.4 Demodulator Output Apply an on-channel RF signal modulated by 1kHz with ±3kHz (±2.4kHz) [±1.5kHz] deviation at an amplitude of –65dBm. Connect an oscilloscope probe (DC coupled) to TP314 (audio output). Check that an audio signal of approximately 800mV peak to peak is present. Optimum tuning of the quad coil (L390) for minimum audio distortion (with a “flat” audio response) should coincide with maximum audio amplitude and a DC level of approximately 1.7V. 5.5.5 IF Distortion If the audio distortion is still high after careful IF alignment (Section 3.7), sweep the IF to investigate the bandpass response. Apply an on-channel RF signal modulated at 10Hz (sine wave) with ±12kHz (±9kHz) [±6kHz] deviation at an amplitude of –80dBm. Connect the modulating 10Hz audio signal to the “X” input of an oscilloscope and observe the 455kHz IF input to SK320 pin 3 via a suitable RF probe on the “Y” input. Alternatively, if you have an RSSI PCB fitted, use an oscilloscope probe for the “Y” input to monitor the RSSI output voltage at pad P238 (RSSI test point) or pin 5 of D-range 1 (PL100). This will give a demodulated log response and only the top half of the wave forms shown in Figure 5.2 and Figure 5.3 will be displayed on the oscilloscope screen. Note: The “X” input should be DC coupled. © Copyright Tait Electronics Limited August 2004. All rights reserved. T855 Fault Finding M8SL2-00-002-812 B5.7 Check that the swept response has a rounded top and no sharp non-linearities (refer to Figure 5.2). Increase the RF level to –50dBm; the trace will now show the shape of the 455kHz ceramic filter (&XF302). Check that the response has no sharp non-linearities. If sharp non-linearities do occur, replace the filter and sweep again to confirm a satisfactory solution (refer to Figure 5.3).

T855 PCB Information M8SL2-00-002-812 6.1 B6.1.3 Introduction Product Type Identification You can identify the receiver type by checking the product code printed on a label on the rear of the chassis (product codes are explained in Section 1 in the front matter of this manual, and Figure 1.1 in Part A shows typical labels). You can further verify the product type by checking the placement of an SMD resistor in the table that is screen printed onto the top side of the PCB, similar to the example drawn below. In this example, the resistor indicates that the product was built as a T855-10-XXXX. 855-30 855-10 855-20 855- 855-13 855-23 855-15 855-25 PRODUCT TYPE Note: PRODUCT TYPE 855-35 The only function of this resistor is to indicate the product type. It has no effect on the circuitry or operation of the receiver. PCB Identification All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02, which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. © Copyright Tait Electronics Limited August 2004. All rights reserved. B6.1.4 T855 PCB Information M8SL2-00-002-812 Parts Lists The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference lists components in alphanumeric order variant column indicates that this is a variant component which is fitted only to the product type listed description gives a brief description of the component Internal Part Number order the component by this number The miscellaneous and mechanical section lists the variant and common parts in IPN order. Variant Components A variant component is one that has the same circuit reference but different value or specification in different product types. Where two products share the same PCB, the term “variant” is also used to describe components unplaced in one product. Variant components have a character prefix, such as “&”, “=” or “#”, before the circuit reference (e.g. &R100). The table below explains the variant prefixes used in T800 SL2 products: If the variant prefix is. . . the component will. . . & change according to channel spacing = change according to frequency stability # change according to frequency range % change or be placed/unplaced for special applications * be unplaced in one product (where two products share the same PCB) © Copyright Tait Electronics Limited August 2004.

T855 PCB Information M8SL2-00-002-812 B6.1.5 Grid Reference Index This section contains a component grid reference index to help you find components and labelled pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alphanumeric order, along with the appropriate alphanumeric grid references, as shown below: PCB layout reference circuit diagram reference components listed in alphanumeric order component location on the sheet sheet number component location on the layer layer number 1 = top side layer 2 = bottom side layer Using CAD Circuit Diagrams Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets. When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g. 1R3).

M8SL2-00-002-812 1.1 T854 General Information C1.5 Introduction The T854 is a synthesised, microprocessor controlled FM base station transmitter designed for single or multichannel operation in the 400 to 520MHz frequency range1 with a standard power output of 25W. The RF section of the transmitter comprises a frequency synthesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band driver stage followed by a 25W power amplifier. A thermal shutdown feature is provided in the T854 in case operating temperatures exceed acceptable levels. The T854 is rated for a continuous output power of 25W at +60°C. This is achieved via a high capacity heatsink, electric fan and shroud. The fan forces air across the heatsink to dissipate the heat. The heatsink replaces one of the usual T800 covers. A wide selection of audio characteristics may be obtained from the audio processor. Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be bypassed or linked to one or both audio inputs, and then back into the remaining audio circuitry in almost any combination. All audio processor options are link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an optional D-range connector (D-range 2 – T800-03-0000) at the rear of the set. All components except those of the VCO are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each section of circuitry. Access to the PCB is primarily through the top cover of the radio, as all components are mounted on the top side of the PCB. There is provision within the chassis to mount small option PCBs. The front panel controls include line sensitivity, microphone socket and carrier switch. This switch turns on the carrier (unmodulated) as an aid to servicing. 1. Although capable of operating over the 400 to 520MHz frequency range, the T854 has an 8MHz switching range (see Section 1.2.3 and Section 3.1). © Copyright Tait Electronics Limited August 2004.

T854 Circuit Operation M8SL2-00-002-812 2.1 C2.3 Introduction The individual circuit blocks which make up the T854 are: • synthesiser • VCO • audio processor • drive amplifier • voltage regulators. Each of these circuit blocks is set in its own shielded compartment, formed as an integral part of the main chassis.

It runs from internal ROM and RAM, thus leaving all four ports free for input/output functions. Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM (IC820). This serial bus is also used by the microcontroller to program the synthesiser (IC740) and deviation control EPOTS (IC220). The main tasks of the microcontroller are as follows: • program the synthesiser and EPOT; • interface with the PGM800Win programming software at 9600 baud via the serial communication lines on D-range 1 (PL100) and D-range 2; • monitor channel change inputs from D-range 2; • generate timing waveforms for CTCSS encoding; • coordinate and implement timing control of the transmitter. • control the front panel “Supply” LED (refer to Section 5.3). © Copyright Tait Electronics Limited August 2004.

T854 Circuit Operation M8SL2-00-002-812 2.3 C2.5 Synthesised Local Oscillator Refer to the synthesiser circuit diagram (Sheet 7 – T854 Synthesiser) in Section 6.2 and the VCO circuit diagram in Part E. VCO Modulation FREQUENCY SYNTHESISER IC 12.8MHz Reference Oscillator Fixed Divider Reference Divider /64 Phase Detector Charge Pump Loop Filter VCO Serial Bus Phase Modulator Clk Data En Buffer Σ /R fref Ref Mod VCO PCB Programmable Divider Prescaler /N 64/65 Output Buffer +22dBm L.O. f in Divider Buffer Controller Figure 2.3 T854 Synthesiser Block Diagram The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled oscillator (VCO) to a given reference frequency. The synthesiser receives the divider information from the control microprocessor via a 3 wire serial bus (clock, data, enable). When the data has been latched in, the synthesiser processes the incoming signals from the VCO buffer (fin) and the phase modulator (fref). A reference oscillator at 12.8MHz (=IC700) is buffered (IC710 pins 3 and 4) and divided down to 200kHz (IC730). This 200kHz square wave is then summed with the modulating audio and passed to an integrator (IC720 pins 9 and 8, Q710, Q720). This produces a ramping waveform which is centred around a DC level determined by the incoming audio. IC720 pins 5 and 6 perform as a comparator, ultimately producing a phase-modulated 200kHz square wave. This is followed by another phase shifting stage (IC720 pins 3 and 4, Q730, Q740), before being divided down to 6.25kHz or 5kHz within the synthesiser IC (IC740). A buffered output of the VCO (Q795) is divided with a prescaler and programmable divider which is incorporated into the synthesiser chip (IC740). This signal is compared with the phase modulated reference signal at the phase detector (also part of the synthesiser chip). The phase detector outputs drive a balanced charge pump circuit (Q760, Q770, Q775, Q780, Q785) and active loop filter (IC750 pins 5, 6 and 7, Q790) which produces a DC voltage between 0V and 20V to tune the VCO. This VCO control line is further filtered to attenuate noise and other spurious signals. Note that the VCO frequency increases with increasing control voltage. If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. This signal is filtered and buffered by IC750 pins 1, 2 and 3, producing the Lock-Detect signal used to shut off the power supply to the drive amplifier. IC750 pin 1 is at 20V when the synthesiser is out of lock. © Copyright Tait Electronics Limited August 2004. All rights reserved. C2.6 T854 Circuit Operation 2.3.1 Two Point Modulation M8SL2-00-002-812 Frequency modulation occurs by modulating both the VCO input and the synthesiser reference input. This process is called two point modulation and ensures a flat modulation response from 67Hz to 3kHz (2.55kHz for narrow bandwidth). The PLL has a fast response time, allowing a Tx key-up time of <30ms. Because of this fast response time the PLL sees lower modulation frequencies superimposed on the VCO as an error and corrects for it, resulting in no modulation on the carrier. At modulation frequencies greater than 300Hz the loop cannot correct fast enough and modulation is seen on the carrier. The response of the loop to VCO modulation is shown by f2 in Figure 2.4 below. To achieve low frequency modulation, the reference oscillator is also modulated so that the phase detector of IC740 detects no frequency error under modulation. Thus, the synthesiser loop will not attempt to correct for modulation and the audio frequency response of the transmitter remains unaffected. The response of the loop to reference frequency modulation is shown by f1 in Figure 2.4. The reference modulation is controlled by a 256-step 10k electronic potentiometer (EPOT) which is adjustable via PGM800Win. The EPOT is made up of 256 resistive sections (representing approximately 39Ω each) which can be individually addressed by the microcontroller. Each section can be switched in or out of circuit to achieve the required total resistance, thus giving control of the reference modulation. f1 f2 TCXO VCO Deviation Frequency Figure 2.4 T854 Two Point Modulation © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 2.4 T854 Circuit Operation C2.7 VCO (Refer to the VCO circuit diagram in Part E.) The VCO transistor (Q1) operates in a common emitter configuration, with an LC tank circuit coupled between its gate and drain to provide the feedback necessary for oscillation. The VCO control voltage from the loop filter (IC750) is applied to the varicaps (D1 and D2) to facilitate tuning within an 8MHz band of frequencies. A trimcap (C6) is used for coarse tuning of the VCO. The output from the oscillator circuit drives a cascode amplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage of amplification, Q5. This is the final amplifier on the VCO PCB, and delivers +20dBm (typically) to the exciter drive amplifier. A low level “sniff” is taken from the input to Q5 and used to drive the divider buffer for the synthesiser (IC740). The VCO operates at the actual output frequency of the exciter, i.e. there are no multiplier stages. It is modulated by superimposing the audio signal onto the control voltage and by phase modulating the reference signal. 2.4.1 VCO Supply The VCO is supplied from two switched +9V supplies under the control of the Tx-Reg. supply. The VCO and buffer amplifier are supplied from one +9V switched supply by Q540 via the C multiplier (Q550, C530 on the T854 and C550 on the T857). The output amplifier is supplied from the other +9V supply by Q520, Q530, and Q510. A delay circuit holds the VCO on for a short time after the Tx-Reg. supply has been switched off. This is to allow the RF power circuits (both exciter and PA) to ramp down in the correct manner before the VCO is switched off. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Figure 2.5 T854 Audio Processor Block Diagram 2.5.1 General The audio processor comprises several link selectable circuit blocks which may be configured in a variety of combinations to suit individual requirements. The pre-emphasis network and compressor may be linked individually or cascaded between either or both audio inputs and the limiter. Refer to Section 3.5.1 for linking details. 2.5.2 Audio Inputs Two audio inputs are available: one from a 600Ω balanced (or unbalanced) line, and the other from a local microphone. The microphone signal is passed first to a pre-amplifier (Q210) and ultimately to a multiplexer (IC240), but in between may pass through the compressor (depending on the linking details). The line transformer is also connected to the multiplexer and is disabled by the microphone PTT switch. A third input for external CTCSS tones is also provided. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 2.5.3 T854 Circuit Operation C2.9 Keying Inputs There are four ways to key the exciter: • pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set); • pushing the “Carrier” button on the front panel – this will inhibit all audio; • using the PTT button on the local microphone, disabling audio from the line; • via the opto-key inputs (pins 11 and 12 on D-range 1 [PL100]) when electrical isolation is required. This features a constant current sink (Q270) to ensure reliable activation of the opto-coupler (IC250) at low keying voltages. 2.5.4 Compressor (Automatic Level Control (ALC)) The input signal is fed via a current controlled attenuator (Q230, Q220) to a high gain stage (IC230) from which the output signal is taken. This signal is passed to a comparator (IC230) which toggles whenever the audio signal exceeds a DC threshold determined by RV220. Thus, the comparator produces a square wave whose mark-space ratio is determined by the amplitude of the audio signal. This square wave pumps up the reservoir capacitor (C233) which controls the attenuator (Q230, Q220), thus completing the feedback loop. The compression level is set by adjustment of the comparator threshold (RV220). Note: Although the high dynamic range of the compressor allows the use of very low audio signal levels, such conditions will be accompanied by a degradation of the signal-to-noise ratio. Very low audio input levels should therefore be avoided where possible. 2.5.5 Outputs To Modulators The output signal from the limiter (IC210, IC230) is summed with a CTCSS tone at a summing amplifier (IC260). The signal is then low pass filtered (IC260) and split to supply the two modulators. Since the VCO modulator is a true frequency modulator, its audio is simply buffered (IC260). The reference modulator, however, is a phase modulator and its audio must first be integrated (IC210). It is vital that the audio levels to the modulators are accurately set, relative to each other. Hence the inclusion of level adjustment in the reference modulator path. Once set, adjustments to absolute deviation may be made only by IC220, a 256-step 10k electronic potentiometer (EPOT), which is controlled via PGM800Win. The EPOT is made up of 256 resistive sections (representing approximately 39Ω each) which can be individually addressed by the microcontroller. Each section can be switched in or out of circuit to achieve the required total resistance, thus adjusting the absolute deviation level. © Copyright Tait Electronics Limited August 2004.

A 5.3V regulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser circuitry. It is also used as the reference for a DC amplifier (IC640, Q630, Q620) which provides a medium current capability 9V supply. The T854 has a regulator (IC370) which produces 9V for use in the exciter and audio circuits. A switching power supply (Q660, Q670) runs from the 9V supply and provides a low current capability +20V supply. This is used to drive the synthesiser loop filter (IC750), giving a VCO control voltage range of up to 20V. Ultimate control of the transmitter is via the Tx-Reg. supply, switched from 9V by Q610. This is enabled via the Tx-Enable signal from the audio processor, and microprocessor. A crowbar diode is fitted for protection against connection to a power supply of incorrect polarity. It also provides transient overvoltage protection. Note: A fuse must be fitted in the power supply line for the diode to provide effective protection. © Copyright Tait Electronics Limited August 2004. All rights reserved. T854 Circuit Operation M8SL2-00-002-812 2.7 C2.11 Transmit Timers The transmit tail timer, transmit timeout timer and transmit lockout timer can all be set from PGM800Win. The fields for setting these are found on the system information page. These three timers operate as follows (refer also to Figure 2.7): Timer Function Adjustment Transmit Tail Sets the tail time during which the transmitter stays keyed after the external key source has been removed. 0 to 5 seconds in 20ms steps Transmit Timeout Sets the maximum continuous transmission time. Once the timer has timed out, the transmitter must be keyed again, unless prevented by the transmit lockout timer. 0 to 600 seconds in 10 second steps Transmit Lockout Sets the period of time that must elapse after a timeout before the transmitter can re-transmit. Once the timer has timed out, the transmitter can be keyed again. 0 to 60 seconds in 10 second steps Tx-Enable On Tx-Reg. Tx-Enable Tail Time On Tx-Reg.

C2.12 T854 Circuit Operation 2.8 T854 Drive Amplifier, Fan Control and PA M8SL2-00-002-812 Refer to Figure 2.1 and the exciter and PA circuit diagrams (sheets 3 and 4) in Section 6.2. The output power of the PA is maintained at a constant level via a power control loop applied to the two-stage, wide band exciter amplifier (Q337, Q336). The forward and reverse RF power levels are sensed via a dual directional coupler and detector diodes (D440, D420 in the PA cavity). The detected DC signals are buffered (IC330 pins 3 and 5) and then summed with the ‘power control’ level and fed to the control integrator (IC350 pin 6). Note: Forward and reflected power signals are summed so that, under high VSWR, the power control will turn the output RF level down. To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. and Lock-Detect signals are gated to inhibit the PA control circuit and to switch off the RF signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator (D340, D380, D360). Cyclic keying control is provided by additional circuitry consisting of several time delay, ramp and gate stages: • Q330, IC350 power ramping • Q326, Q325, Q341 Tx-Reg. and Lock-Detect gate • Q335, Q340, Q345 delay and PIN switch drive. This is to allow the RF power circuits (both exciter and PA) to ramp up and down in a controlled manner so that minimal adjacent channel interference is generated during the transition. The output of the wide band amplifier is approximately 1W (+30dBm) for an input of 100mW (+20dBm) from the VCO, when the power control is set to maximum. A temperature sensor (R481) in the PA cavity presents a voltage to the comparators of IC340 pin 2 and IC350 pin 2. The fan is switched on and off by the comparator of IC340 and the power fold-back is enabled by the comparator of IC350. Power fold-back reduces the output power to a preset level that protects the PA semiconductors from excessive temperatures. Under normal operating conditions, the fan will be activated before power fold-back can occur and it will prevent the temperature from reaching damaging levels. The voltage divider ratio of R311 and R312 sets the the temperature at which the fan is switched on and off. R306 and R340 set the temperature at which power is reduced. Depending on ambient temperature and ventilation, it may take several minutes of continuous operation for the fan to be activated. #R517, #R518 and #R519 form an attenuator to provide good VCO/exciter isolation as well as the correct exciter drive level. The attenuator (#R395, #R396 and #R397) aids in producing the correct exciter drive level to the PA over the three frequency ranges. © Copyright Tait Electronics Limited August 2004.

M8SL2-00-002-812 3.1 T854 Initial Tuning and Adjustment C3.3 Introduction When you receive your T854 transmitter it will be run up and working on a particular frequency (the “default channel")1. If you want to switch to a frequency that is within the 8MHz switching range (i.e. ±4MHz from the factory programmed frequency), you should only need to reprogram the transmitter with the PGM800Win software (refer to the PGM800Win programming kit and Section 3.2 below). However, if you want to switch to a frequency outside the 8MHz switching range, you will have to reprogram and re-tune the transmitter to ensure correct operation. In this case you should carry out the short tuning procedure described in Section 3.4. If you have carried out repairs or other major adjustments, you must carry out the full tuning and adjustment procedure described in this section (except for Section 3.4). 3.2 Channel Programming You can program up to 128 channel frequencies into the transmitter’s EEPROM memory (IC820) by using the PGM800Win software package and a PC. You can also use PGM800Win to select the transmitter’s current operating frequency (or “default channel"). If the transmitter is installed in a rack frame, you can program it via the programming port in the speaker panel. However, you can also program the transmitter before it is installed in a rack frame as follows: • by using a T800-01-0010 calibration test unit; • via D-range 1; • via D-range 2 (standard T800-03-0000 auxiliary D-range only); • via SK805 (internal Micromatch connector). If you do not use the T800-01-0010, you will have to connect the PC to the transmitter via a module programming interface (such as the T800-01-0004). For a full description of the channel programming procedure, refer to the PGM800Win programming software user’s manual. Note: When an auxiliary D-range kit (D-range 2 – T800-03-0000) is fitted, you can also select a channel with an external switch, such as the DIP switch on a backplane PCB. Refer to your nearest Tait Dealer or Customer Service Organisation for further details. 1. Use the “Read Module” function in PGM800Win to find out what the default channel is. © Copyright Tait Electronics Limited August 2004. All rights reserved.

C3.6 T854 Initial Tuning and Adjustment 3.4.4 Two Point Modulation Adjustment Note 1: In this and following sections deviation settings are given first for wide bandwidth sets, followed by settings in brackets for mid bandwidth sets ( ) and narrow bandwidth sets [ ]. Note 2: The reference modulation and limiter adjustments are controlled by 256step electronic potentiometers (EPOTs), which are adjusted via the “Reference Modulation” and “Deviation” settings in PGM800Win. This allows the two point modulation and deviation settings to be adjusted for each channel. Note 3: To optimise the modulation response across the switching range, repeat steps 1 to 4 below for each channel that will be used (usually needed only for data applications). In applications where the modulation response is less critical (e.g. voice use only), carry out steps 1 to 4 below on the middle channel and use the “EPOT Fill” option1 in PGM800Win to copy the value to the other channels. Note 4: If you are using an RF test set, turn the low pass filter off and set the high pass filter to 15kHz before beginning this procedure. 1. M8SL2-00-002-812 Inject an audio signal of 300Hz 1.5Vrms (+5dBm) into the CTCSS input (D-range 1 (PL100) pin 8). Key the transmitter by earthing the Tx-Key line. 2. Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation at 300Hz. 3. Change the input frequency to 100Hz and, using PGM800Win, adjust the value of the “Reference Modulation” EPOT setting for the current channel to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation (you can use either the mouse or up and down arrow keys). 4. Change the input frequency back to 300Hz. Repeat steps 2 and 3 above until the deviations achieved at the two input frequencies are within 0.2dB of each other. You will need to do this at least four times. 5. Sweep the audio between 50 and 300Hz for peaks. Note: A peak between 50 and 300Hz will indicate a fault condition, i.e: or – incorrect set-up – modulation circuitry fault. The specification window is ±1dB relative to 150Hz from 67 to 260Hz. 1. Use the “EDIT FILL” button on the tool bar or go to “Edit”, “Fill”, “Epot Settings” on the menu bar. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 3.4.5 T854 Initial Tuning and Adjustment C3.7 CTCSS Encoder (If Used) Program a CTCSS tone on the default channel using PGM800Win. If you are using an RF test set, turn off the 300Hz high pass filter. Key the T854 with the front panel “Carrier” switch. Adjust RV805 (CTCSS level adjust) to give ±500Hz (±350Hz) [±250Hz] deviation. Set the maximum deviation as per Section 3.4.6. 3.4.6 FM Deviation (Limiter) Adjustment Note: If the T854 will be used over the whole 8MHz switching range, you must set the deviation for each channel. However, if the module will be used on frequencies that cover only a 1MHz (or less) switching range, you can set the deviation on the middle channel and use this value for all other channels with the “EPOT Fill” option in PGM800Win. Inject 1kHz at –10dBm into the line input (D-range 1 (PL100) pins 1 and 4; pins 2 and 3 shorted; refer to Section 1.5 of Part G). Adjust RV210 (line sensitivity) fully clockwise and key the transmitter by earthing the Tx-Key line. Using PGM800Win, adjust the value of the “Deviation” EPOT setting for the current channel to obtain a deviation limit of ±4.7kHz (±3.8kHz) [±2.3kHz] (you can use either the mouse or up and down arrow keys). Sweep the audio frequency from 100Hz to 4kHz and ensure that the maximum deviation does not exceed ±4.7kHz (±3.8kHz) [±2.3kHz]. Readjust “Deviation” if necessary via PGM800Win. 3.4.7 Line-in Level Adjustment Remove the CTCSS signal (if used). Set the injected signal at the line input to the required line level (typically –10 to –20dBm). Adjust RV210 (line sensitivity) to provide ±3kHz (±2.4kHz) [±1.5kHz] deviation.

M8SL2-00-002-812 T854 Initial Tuning and Adjustment 3.9 Audio Processor and CTCSS 3.9.1 Two Point Modulation C3.11 The T854 utilises two point modulation to obtain a wide audio bandwidth independent of the synthesiser loop filter response. This is achieved by simultaneously frequency modulating the VCO and phase modulating the synthesiser reference frequency. The relative signal levels fed to the two modulators are quite critical and cause interaction when setting up. Both modulating signals require readjustment when the exciter is shifted in frequency greater than the switching range (i.e. ∆F>±4MHz). Note 1: In this and following sections deviation settings are given first for wide bandwidth sets, followed by settings in brackets for mid bandwidth sets ( ) and narrow bandwidth sets [ ]. Note 2: The reference modulation and limiter adjustments are controlled by 256step electronic potentiometers (EPOTs), which are adjusted via the “Reference Modulation” and “Deviation” settings in PGM800Win. This allows the two point modulation and deviation settings to be adjusted for each channel. Note 3: To optimise the modulation response across the switching range, repeat steps 1 to 4 below for each channel that will be used (usually needed only for data applications). In applications where the modulation response is less critical (e.g. voice use only), carry out steps 1 to 4 below on the middle channel and use the “EPOT Fill” option1 in PGM800Win to copy the value to the other channels. Note 4: If you are using an RF test set, turn the low pass filter off and set the high pass filter to 15kHz before beginning this procedure. 3.9.2 Modulator Adjustment 1. Inject an audio signal of 300Hz 1.5Vrms (+5dBm) into the CTCSS input (D-range 1 (PL100) pin 8). Key the transmitter by earthing the Tx-Key line. 2. Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation at 300Hz. 3. Change the input frequency to 100Hz and, using PGM800Win, adjust the value of the “Reference Modulation” EPOT setting for the current channel to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation (you can use either the mouse or up and down arrow keys). 1.

T854 Initial Tuning and Adjustment M8SL2-00-002-812 Change the input frequency back to 300Hz. Repeat steps 2 and 3 above until the deviations achieved at the two input frequencies are within 0.2dB of each other. You will need to do this at least four times. 5. Note: Sweep the audio between 50 and 300Hz for peaks. A peak between 50 and 300Hz will indicate a fault condition, i.e: or – incorrect set-up – modulation circuitry fault. The specification window is ±1dB relative to 150Hz from 67 to 260Hz. 3.9.3 CTCSS Encoder (If Used) 1. Program a CTCSS tone on the default channel using PGM800Win. 2. If you are using an RF test set, turn off the 300Hz high pass filter. 3. Key the T854 with the front panel “Carrier” switch. 4. Adjust RV805 (CTCSS level adjust) to give ±500Hz (±350Hz) [±250Hz] deviation. 5. Set the maximum deviation as per Section 3.9.4. 3.9.4 Limiter Adjustment Note: If the T854 will be used over the whole 8MHz switching range, you must set the deviation for each channel. However, if the module will be used on frequencies that cover only a 1MHz (or less) switching range, you can set the deviation on the middle channel and use this value for all other channels with the “EPOT Fill” option in PGM800Win. 1. Set the links in the audio processor section as required (refer to Section 3.5). 2. Inject 1kHz at –10dBm into the line input (D-range 1 (PL100) pins 1 and 4; and pins 2 and 3 shorted; refer to Section 1.5 of Part G). 3. Adjust RV210 (line sensitivity) fully clockwise and key the transmitter by earthing the Tx-Key line. Using PGM800Win, adjust the value of the “Deviation” EPOT setting for the current channel to obtain a deviation limit of ±4.7kHz (±3.8kHz) [±2.3kHz] (you can use either the mouse or up and down arrow keys). 4. Sweep the audio frequency from 100Hz to 4kHz and ensure that the maximum deviation does not exceed ±4.7kHz (±3.8kHz) [±2.3kHz].

M8SL2-00-002-812 3.9.5 T854 Initial Tuning and Adjustment C3.13 Line Level Without Compressor This section assumes that the compressor is not used. If the compressor is required, refer to Section 3.9.6. 1. Remove the CTCSS signal (if used). 2. Adjust the line sensitivity as follows: • set the injected signal at the line input to the required line level (typically –10 to –20dBm) • adjust RV210 (line sensitivity) to provide ±3kHz (±2.4kHz) [±1.5kHz] deviation 3. 3.9.6 Reapply the CTCSS signal (if required). Compressor The compressor may be used on the line input only, the microphone input only, or on both the line and microphone inputs. If the compressor is used, refer to one of the following sections as appropriate. 3.9.6.1 Compressor On Line Input Only 1. Set RV210 (line sensitivity) fully clockwise and key the transmitter by earthing the Tx-Key line. 2. Reduce the line level to –50dBm at 1kHz and set RV220 (compression level) fully clockwise. 3. Check that ±3kHz deviation (±2.4kHz) [±1.5kHz] is still available. 4. Slowly increase the audio input level until the demodulated waveform shows significant signs of clipping (approximately ±4.5kHz (±3.6kHz) [±2.3kHz] deviation). 5. Adjust RV220 anticlockwise until the demodulated waveform is just clipping (approximately ±4kHz (±3.2kHz) [±2kHz] deviation). 6. Increase the input level to –10dBm and check that the test tone is still held just into clipping. The input line level should be typically –10 to –20dBm. 3.9.6.2 Compressor On Microphone Input Only 1. Key the transmitter by earthing the Tx-Key line and plug a microphone jack into the front panel socket. 2. Adjust RV220 (compression level) fully clockwise. 3. Acoustically couple the microphone to a tone box (1kHz) and close the PTT switch. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Increase the audio level until the demodulated waveform shows significant signs of clipping (approximately ±4.5kHz (±3.6kHz) [±2.3kHz] deviation). 5. Adjust RV220 anticlockwise until the demodulated waveform is just clipping (approximately ±4kHz (±3.2khz) [±2kHz] deviation). 6. Increase the audio level by 10dB and verify that the test tone is held just into clipping. 7. Whistle steadily into the microphone, checking that approximately ±4kHz (±3.2khz) [±2kHz] deviation is produced. The modulated waveform should be basically sinusoidal. 8. Speak into the microphone, checking that the modulation peaks reach about ±5kHz (±4kHz) [±2.5kHz] deviation. 9. As the line is to be used without compression, set RV210 (line sensitivity) as described in Section 3.9.5. 3.9.6.3 Compressor On Both Line and Microphone Inputs Set up as described in Section 3.9.6.1. 3.10 Power Alarms (if used) When fitted to the T854 transmitter an alarm board monitors the transmitter output power and generates a low forward-power and/or high reverse-power alarm as appropriate. This is achieved by monitoring the output voltages of the transmitters forward and reverse power directional coupler. A comparison between these voltage levels and user defined reference voltages generates alarm conditions accordingly. The low forward power output signal is also gated with the Tx-enable input to ensure that no alarm is generated when the transmitter is not transmitting. The high reverse power alarm output is not gated. The alarm signal is output on the T854 Aux D-range. There are two alarms boards currently available, the recently introduced and improved T800-10-0520 Tx-Alarm/Channel Select board and the older T1500-52-0000, which it replaces. The alarm outputs of both the these boards are compatible with the T1511-20-0000 CCM module and the T803-02 Tone Remote and Alarm interface. © Copyright Tait Electronics Limited August 2004.

Turn the transmitter OFF. 3.10.2 T800-10-0520 Tx-Alarm/Channel-Select Kit When fitted to a T854 transmitter, the T800-10-0520 Tx-Alarm/Channel-Select plug-in board provides the following features: • The plug-in board monitors the transmitter’s output power, and generates a low forward-power and/or high reverse-power alarm as appropriate. • The plug-in board also includes channel select switches that enables the user to manually set the operational channel of the T854. The plug-in board provides the same alarm outputs as the T1500-52-0000: Note: • Forward Power Alarm: Aux D-range pin 13 • Reverse Power Alarm: Aux D-range pin 14 AUX-OUT-0 is disabled when the plug-in board is installed. The Tx-Alarm function is achieved by comparing the output voltages of the transmitter’s directional coupler to user-defined reference levels. The low forward-power alarm output is gated with the Tx-Enable input, to ensure that no alarm is generated when the transmitter is not transmitting. The high reverse-power alarm is not gated. Note: The plug-in board does not require additional wiring. It can be set up on the bench. This is possible because the Tx-Enable line is accessed from inside the T854, rather than from the backplane PCB (as on the T1500-52-0000).

C4.4 T854 Functional Testing 4.4 Timers M8SL2-00-002-812 The transmit tail timer, transmit timeout timer and transmit lockout timer can all be set from PGM800Win. The fields for setting these are found on the system information page. These three timers operate as follows (refer also to Figure 4.1): Timer Function Adjustment Transmit Tail Sets the tail time during which the transmitter stays keyed after the external key source has been removed. 0 to 5 seconds in 20ms steps Transmit Timeout Sets the maximum continuous transmission time. Once the timer has timed out, the transmitter must be keyed again, unless prevented by the transmit lockout timer. 0 to 300 seconds in 20 second steps Transmit Lockout Sets the period of time that must elapse after a timeout before the transmitter can re-transmit. Once the timer has timed out, the transmitter can be keyed again. 0 to 60 seconds in 10 second steps Tx-Enable On Tx-Reg. Tx-Enable Tail Time On Tx-Reg.

M8SL2-00-002-812 4.5 T854 Functional Testing C4.5 Frequency Response If the T854 has been correctly adjusted, the pre-emphasis and limiting responses should closely match those shown in Figure 4.2 and Figure 4.3 respectively. Note: The limits shown on these graphs should not be exceeded. 1. If you are using an RF test set, turn off all filters. 2. Measure the pre-emphasis response as follows: Reduce the line level to give ±1kHz (±0.8kHz) [±0.5kHz] deviation at 1kHz. Sweep the modulation frequency. The response should closely match that shown in Figure 4.2. 3. Measure the limiting response as follows: Set the line level to give ±3kHz (±2.4kHz) [±1.5kHz] deviation at 1kHz. Increase the line level 20dB and sweep the modulation frequency. © Copyright Tait Electronics Limited August 2004. All rights reserved.

T854 Fault Finding M8SL2-00-002-812 5 C5.1 T854 Fault Finding Caution: This equipment contains CMOS devices which are susceptible to damage from static charges. Refer to Section 1.2 in Part A for more information on anti-static procedures when handling these devices. The following test procedures and fault finding flow charts may be used to help locate a hardware problem, however they are by no means a complete fault finding procedure. If you still cannot trace the fault after progressing through them in a logical manner, contact your nearest Tait Dealer or Customer Service Organisation. If necessary, you can get additional technical help from Technical Support, Tait Electronics Ltd, Christchurch, New Zealand (full contact details are on page 2). Note 1: In this and following sections deviation settings are given first for wide bandwidth sets, followed by settings in brackets for mid bandwidth sets ( ) and narrow bandwidth sets [ ]. Note 2: Unless otherwise specified, the term “PGM800Win” used in this and following sections refers to version 4.02 and later of the software. Refer to Section 6 where the parts lists, grid reference index and diagrams will provide detailed information on identifying and locating components and test points on the main PCB. The parts list and diagrams for the VCO PCB are in Part E.

All rights reserved. T854 Fault Finding M8SL2-00-002-812 5.1 C5.3 Visual Checks Remove the top cover from the T854 and inspect the PCB for damaged or broken components, paying particular attention to the surface mounted devices (SMDs). Check for defective solder joints. If repair or replacement is considered necessary, refer to Section 3 of Part A. 5.2 Component Checks If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, first make sure that the transistor is not shunted by some circuit resistance. Use a good quality EVM (e.g. Fluke 75) for taking the measurements (or a 20kΩ/V or better multimeter, using only the medium or low resistance ranges). The collector current drawn by multi-junction transistors is a further guide to their performance. If an IC is suspect, the most reliable check is to measure the DC operating voltages. Due to the catastrophic nature of most IC failures, the pin voltages will usually be markedly different from the recommended values in the presence of a fault. The recommended values can be obtained from either the circuit diagram or the component data catalogue. 5.3 Front Panel LED Indicator The green “Supply” LED on the T854 front panel will flash according to the conditions described in the following table: Flash Rate Condition fast ( 1/3 s on/ 1/3 s off approx.) T854 is linked with PGM800Win unequal ( 1/3 s on/1s off approx.) microcontroller has detected an internal communications error – refer to Section 5.7.1 Where two or more conditions occur at the same time, the precedence is in the order shown above (i.e. T854 linked has the highest priority, followed by internal error). © Copyright Tait Electronics Limited August 2004. All rights reserved. C5.4 T854 Fault Finding 5.4 DC Checks 5.4.1 Power Rails M8SL2-00-002-812 Refer to the test points and options diagrams in Section 6 for test point locations, and to the regulator fault finding chart (Section 5.7.2) for fault diagnosis. Check the 13.8V (TP601) and 9V (TP602) supplies at their test points in the regulator compartment with a DMM. Check the 5V (TP604) and 20V (TP603) rails at their respective test points in the regulator compartment. Check that Tx-Reg. (TP305 in the exciter compartment) comes up to 8.8V when the exciter is keyed. Check the +5V digital regulator output (TP607 in the regulator compartment). Check the 9V supply (IC370 pin 1) with a DMM. Check for short circuits. 5.4.2 VCO Locking Key the exciter. Using a DMM, monitor the VCO control voltage between between L1 and PL14 pin1 on the VCO PCB. If the synthesiser is locked and the VCO aligned, the voltage at this point should be between 3 and 16V. If the VCO is not locked, refer to the synthesiser fault finding chart (Section 5.7.3). © Copyright Tait Electronics Limited August 2004. All rights reserved. T854 Fault Finding M8SL2-00-002-812 5.5 C5.5 RF Checks In-circuit RF levels may be measured with an RF probe on which the earth lead has been shortened to a minimum (i.e. 13mm). Refer to the circuit diagrams for typical levels. Figure 5.1 shows a suitable RF probe circuit. 1n Probe Coax 10k DC to DVM or Oscilloscope 1N6263 1n 100k Earthing Clip This unit is not suitable for use on high power RF circuits. Figure 5.1 RF Diode Probe Circuit 5.5.1 T854 Drive Power Refer to the drive amplifier fault finding chart (Section 5.7.4). Ensure that the VCO locks (refer to Section 5.4.2). Connect the drive output to a power meter and key the transmitter. Check that the exciter output power (SK310) is >1.5W. Note: If the synthesiser is out of lock, the lock detector (synthesiser IC740 and comparator IC750) will prevent the RF signal from reaching the PA by switching the supply to the exciter amplifier (Q336, Q337). 5.5.2 T854 PA Output Power Reconnect the drive output to the PA input. Connect the PA to a power meter and key the transmitter. Check that the output power is >30W with RV310 (power control) adjusted fully clockwise. 5.5.3 Audio And Modulation Refer to the audio processor fault finding chart (Section 5.7.6). Set up the audio processor as described in Section 3.9. © Copyright Tait Electronics Limited August 2004. All rights reserved. C5.6 T854 Fault Finding M8SL2-00-002-812 Check that the demodulated RF output has the frequency response referred to in Section 4.5 with at least ±5kHz (±4kHz) [±2.5kHz] deviation available at 1kHz modulating frequency. If the above result is not achieved, either the dual point modulation is incorrectly adjusted or a fault condition exists. 5.6 PGM800Win Generated Errors The following errors are those most likely to occur using PGM800Win. Refer to the PGM800Win software user’s manual for a complete list of error messages. Channel Switch Set The programmed default channel change was not accepted by the base station because a channel is selected externally. Try turning the external channel switch off to change the default channel in PGM800Win. Synth Out Of Lock The synthesiser received incorrect data, or the data was corrupted. Enter a frequency within the VCO switching range, or tune the VCO. Internal Error Data could not be read from the base station due to an internal error. Check for shorts or open circuits on the SDA, SCK, SYNTH and EPOT lines. The SDA, SCK and SYNTH are normally high, and the EPOT is normally low. Write/Read To An Unlinked Module The link to the module does not exist. Undefined error. © Copyright Tait Electronics Limited August 2004. All rights reserved.

T854 Fault Finding M8SL2-00-002-812 5.8 C5.17 To Replace The T854 PA Transistors (Q410 and Q420) Caution: Failure to comply with the following procedure can result in failure of the device due to poor heatsinking, or worse, can endanger the health of the assembler if the beryllium oxide die carrier is smashed during assembly. Caution: As the location of certain components in the PA is critical to performance, it is important that any components removed or disturbed are refitted in exactly the same position. Before attempting to remove a transistor, measure the distance between the capacitors and transistor body to the nearest 0.5mm (measurement “A” in Figure 5.2) so that the capacitors can be replaced in exactly the same position. These measurements are shown in Figure 5.2 for the 6LFL package, however the same procedure applies for the SOE (stud) package. Caution: Do not apply too much heat or pressure to the PCB pads and tracks as you may damage them or lift them from the PCB, causing permanent damage to the transmitter. base collector measurement A Figure 5.2 Typical Transistor/Capacitor Spacing (Not To Scale) Desolder and remove the components from around the transistor. Q420 Only: Desolder and remove the two solder tags. Desolder the transistor tabs by heating with a soldering iron and lifting away from the PCB with a screwdriver or thin stainless steel spike, then remove the device. © Copyright Tait Electronics Limited August 2004. All rights reserved. C5.18 T854 Fault Finding Q410 Only: M8SL2-00-002-812 Unscrew the transistor stud nut and remove the device. Remove any excess solder from the PCB pads with solder wick. Trim the tabs of the replacement transistor so that the device sits neatly on the PCB pads provided. Lightly tin the underside of the transistor tabs. Remove any excess solder to leave a thin, even layer on the tabs. Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) to the transistor mounting surface. Sufficient compound should be used to ensure an even film over the entire mounting surface. Place the transistor on the PCB in the correct orientation and ensure the tabs are flush to the surface. Q410 Only: Caution: Lightly solder one tab to the PCB, then torque down the retaining nut to the correct torque (0.7Nm/6in.lbf.). Do not solder all the tabs before torquing down otherwise the device may be broken. Q420 Only: Refit the solder tags. Solder all transistor tabs to the PCB. Replace each component in exactly the same position as noted previously. © Copyright Tait Electronics Limited August 2004. All rights reserved. T854 PCB Information M8SL2-00-002-812 6 C6.1.1 T854 PCB Information Caution: This equipment contains CMOS devices which are susceptible to damage from static charges. Refer to Section 1.2 in Part A for more information on anti-static procedures when handling these devices. This section provides the following information on the T854 transmitter: • parts lists • grid reference indexes • mechanical assembly drawings • PCB layouts • test points and options connections drawings • circuit diagrams.

T854 PCB Information M8SL2-00-002-812 6.1 C6.1.3 Introduction Product Type Identification You can identify the transmitter type by checking the product code printed on a label on the rear of the chassis (product codes are explained in Section 1 of the front matter in this manual, and Figure 1.1 in Part A shows typical labels). You can further verify the product type by checking the placement of an SMD resistor in the table that is screen printed onto the top side of the PCB, similar to the example drawn below. In this example, the resistor indicates that the product was built as a T854-10-XXXX. 854-30 854-10 854-20 854- 854-13 854-23 854-15 854-25 PRODUCT TYPE Note: PRODUCT TYPE 854-35 The only function of this resistor is to indicate the product type. It has no effect on the circuitry or operation of the transmitter. PCB Identification All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02, which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. © Copyright Tait Electronics Limited August 2004.

We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference lists components in alphanumeric order variant column indicates that this is a variant component which is fitted only to the product type listed description gives a brief description of the component Internal Part Number order the component by this number The miscellaneous and mechanical section lists the variant and common parts in IPN order. Variant Components A variant component is one that has the same circuit reference but different value or specification in different product types. Where two products share the same PCB, the term “variant” is also used to describe components unplaced in one product. Variant components have a character prefix, such as “&”, “=” or “#”, before the circuit reference (e.g. &R100). The table below explains the variant prefixes used in T800 SL2 products: If the variant prefix is. . . the component will. . . & change according to channel spacing = change according to frequency stability # change according to frequency range % change or be placed/unplaced for special applications * be unplaced in one product (where two products share the same PCB) © Copyright Tait Electronics Limited August 2004.

T854 PCB Information M8SL2-00-002-812 C6.1.5 Grid Reference Index This section contains a component grid reference index to help you find components and labelled pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alphanumeric order, along with the appropriate alphanumeric grid references, as shown below: PCB layout reference circuit diagram reference components listed in alphanumeric order component location on the sheet sheet number component location on the layer layer number 1 = top side layer 2 = bottom side layer Using CAD Circuit Diagrams Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets. When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g. 1R3).

All rights reserved. M8SL2-00-002-812 1.1 General Information D1.3 Introduction The T803-02 is a tone-operated Remote Controller otherwise known as a Tone Remote. Features include alarm monitoring, voting tone generation and simple high site control. It interfaces either a 2-wire or 4-wire line circuit to the T800 SL2 Base Station and thus enables a dispatch console (also known as a desktop controller) to monitor and control the remote basestation. The T803-02 interfaces with the SL2 receiver and transmitter via the backplane PCB (X800-56-PCB3) and two small flat cable looms plugged into the Dranges on the back. The T803 is configured using the Tait PGM800Win programming software (V4.02 and later) on a PC. 1.1.1 Tone Remote The T803 tone remote enables a remotely located user to: • key the transmitter • defeat the receiver’s CTCSS mute (to monitor a channel) • change the set channel (up to 256 channels) • change between base station and repeater modes (repeater knockdown) • monitor and cancel alarms • turn repeater site equipment on or off (highsite control) • loop back line audio (4-wire line interface only) This is achieved using three industry-standard tone signalling plans for ease of integration into existing control systems and choice of vendor for office/control room equipment. These plans are: • EIA tone remote using a single function tone. In this system when the control room user presses the transmit key, the line control equipment sends a 120ms long burst of high level guard tone (HLGT – usually 2175Hz at +10dBM to line). This is followed by a single 40ms function tone at 0dBm to line. The available tone set is 650Hz to 2050Hz in 100Hz steps. This function tone can change channel, monitor the radio channel (defeat receiver CTCSS) or a variety of other functions. Following these initial tone bursts a low level guard tone (LLGT – usually 2175Hz at –20dBm) is sent to line and speech is gated onto line (at approx 0dBm peak level). This continues until the user releases the transmit key. This removes speech from the line and low level guard tone ceases. • EIA enhanced tone remote using two function tones. This is a variant of the above system where two function tones are sent one after the other in the period between the high level guard tone and the low level guard tone. The tone set is also expanded (650Hz to 2050Hz in 100Hz steps) to give 225 possible combinations which can be allocated to various actions. The duration of both high level guard tone and function tones can be varied. • Simple Transmitter keying using low level guard tone. This is used where complex functionality is not required. One application is to key a link transmitter where the high level guard tone, the function tones, speech and low level guard tones are transparently carried to an end base station. Note that in © Copyright Tait Electronics Limited August 2004. All rights reserved. D1.4 General Information M8SL2-00-002-812 this application the notch filters (which ordinarily remove the key tone from the audio path) must be turned off using PGM800Win so that the keying signal is propagated to the end transmitter. 1.1.2 Alarm Monitoring and Confirmations The T803 monitors three T800 sub-rack alarms (transmitter forward and reverse power, and low battery/power supply), one line alarm (line fail indication) and four external closure alarms. If alarms are triggered the T803 can be programmed to generate tone sequences (DTMF, Selcall or function tones) and/or enable auxiliary outputs, to alert system users of a problem. The tone sequences can be sent to line and/or radio. Additionally the T803-02 can be programmed to respond to as many as eight different non-alarm triggers. These can be used as confirmation that an event has occurred. Confirmations can be programmed to occur in the event of power-up, channel change and/ or the detection of up to six user defined function tones. In the same way as for alarms, the T803 can generate tone sequences and/or enable auxiliary outputs as a response to a confirmation. 1.1.3 Voting Tones The T803 can also generate voting tones where a 4-wire line interface is used. Voting systems are used where several base station receivers are tuned to the same radio channel and located at different sites, sending audio back to a central control where the best quality audio must be selected or “voted upon”. Tone on Idle or Sliding Voting Tones can be generated to interface a T800 sub-rack to a wide variety of industry standard Radio Voting systems. In Tone on Idle applications, a tone (normally the same frequency as LLGT) is transmitted to line when the T800 receiver is muted. When the tone disappears, control room equipment can perform signal to noise measurements on incoming audio lines and select the best for feeding to the control room user. In Sliding Voting Tone systems, a tone is transmitted to line whose frequency is proportional to the T800 receiver’s RSSI. Control room equipment determines which receiver has the highest RSSI and thus selects which line carries the highest quality incoming audio. 1.1.4 Other Features • Programmable Morse Code Encoder for automatic station identification (CWID) • User programmable Line levels • Programmable Transmit and Receive audio path delays • Programmable (on/off) notch filtering. © Copyright Tait Electronics Limited August 2004.

On the secondary of these line matching transformers are analogue transmission switches which configure the line interface as either 2-wire or 4-wire compatible. Audio from line is passed through a programmable electronic potentiometer (e-pot) level control circuit before entering a CODEC where it is digitised. Audio to line is output from the same line CODEC, via a second programmable e-pot level control circuit. The line CODEC is connected to a digital signal processor (DSP) which is also connected to a similar radio CODEC (the CTCSS CODEC is not used in this application). The radio CODEC receives audio from the T800 receiver and sends audio to the T800 transmitter to which it is connected via the special backplane PCB. Receiver audio is low frequency filtered to extend the radio CODEC’s effective frequency range. The DSP processes the digitised audio streams from the CODECs in accord with instructions sent to it by the T803’s microcontroller. The DSP can: • detect high level guard tone, low level guard tone and function tones coming from line, notch filter line in and receiver audio (used to eliminate low level guard tone from line out and transmitter audio); • generate Selcall DTMF/function tone alarms and pip tones to Line-Out and transmitter audio; • generate voting tones to Line-Out; • generate morse code to transmitter audio; • cross connect line and radio audio paths; • adjusts the Line-In and Line-Out levels; © Copyright Tait Electronics Limited August 2004. All rights reserved. D2.4 Circuit Operation M8SL2-00-002-812 • mute audio from Line-In and receiver; • delay the audio. The microcontroller boot loads the DSP, interfaces with the user via the front panel switches and LEDs, interfaces with PGM800Win and runs the T803 state machines (alarm monitoring, alarm tone generation, high level guard tone/function tone/low level guard tone timing, RSSI/voting tone conversion etc.). 2.2 Tone Detection In the quiescent state, audio on the Line-In pair is passed through the DSP (IC300) unfiltered to the T803 loudspeaker (which is connected to Tx audio – TP203). The audio is bandpass filtered to detect guard tone. In normal operation (keytone and function tone operation) the tone detector threshold is set for high level guard tone (HLGT). If HLGT is detected, the DSP signals this detection to the micro using the TONE_DETECT line (TP300 is pulled low). The micro instructs the DSP, using the asynchronous serial communications connection (TP306) between them, to switch on the in line guard tone notch filter, lower the threshold of the guard tone detector (so that it can detect low level guard tone – LLGT) and turn on the function tone detectors. Where the T803 is operating in 2-wire mode and receiver audio (RX audio) is being gated to line, the micro will soft mute the RX audio first). The micro then starts an internal timer, the duration of which is set by the HLGT and function tone times programmed by PGM800Win. If a function tone is detected, the DSP signals the micro using the CALL_UP line (TP301 pulled low). The micro then interrogates the DSP via the serial communications connection to find out what frequency was detected. If no tones are detected and the timer expires, the micro resets the DSP to its quiescent state. If two different frequencies are detected or if only one function tone frequency is decoded and the timer expires, the micro decodes them/it into an action by reading data programmed into the EEPROM (IC312) by PGM800Win. The micro then keys on the transmitter (PTT line) and instructs the DSP to turn off the function tone detectors and the talk-through gate (if it was on). If the function tone sequence decodes into a channel number that is different from the currently set channel, the micro will output the channel number on CH0 – CH7 for 250ms. This change may be latched into the T800 radios providing the sub-rack PCB channel select switches do not create a conflict. As long as the DSP is detecting LLGT (indicated by a low level on TP300) the micro will keep the transmitter keyed on. When the DSP fails to detect LLGT the micro turns off the transmitter key and returns the DSP to the quiescent state. When the T803 is programmed for keytone-only operation, the micro keying of the transmitter follows the state of the TONE_DETECT line from the DSP. In the quiescent state when the receiver mute line (RX_MUTE) goes low, the micro instructs the DSP to gate audio from the receiver to Line-Out. If the line interface is 2wire, Line-In and Line-Out are joined and the Rx audio will pass through the line inter- © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 Circuit Operation D2.5 nally to the loudspeaker. It will therefore also reach the guard tone detector. Rx audio is therefore notch filtered at the guard tone frequency to prevent false guard tone detection. If the line interface is 4-wire this filtering is unnecessary but the talk-through gate must be turned on to send Rx audio to the loudspeaker. If the T803 is in repeater mode the transmitter is keyed and will remain so until the RX_MUTE line goes high. Note that the T803 will not key the transmitter if the receiver’s CTCSS is defeated (CD_OUT is low) to prevent receiver channel noise being transmitted. From the description above of the keytone/function tone detection it can be seen that keying from line has priority over repeater mode keying and audio gating. 2.3 Alarm Monitoring The T803 microprocessor monitors eight alarm sources: • Transmitter forward power • Transmitter reverse power • low battery • line fail • four external closure alarms When an alarm is triggered it is latched as indicated by the corresponding LED on the front panel. If the T803 is keying the transmitter or sending receiver audio to the line the latched alarm is ignored. Once the T803 re-enters the idle state the latched alarms are actioned. The microprocessor reads the EEPROM to determine what tone sequence the user programmed and instructs the DSP accordingly. If the tone sequence is to be sent to the transmitter, it is keyed 500ms before the tones are generated. Additionally the user may program any of the 4 auxiliary output ports as a response to an alarm event. The micro will activate (pull low) these outputs if enabled. If several alarms are latched together they are actioned in the order of priority: 1. External closure alarms 0 to 3 2. Reverse power 3. Forward power 4. Low battery 5. Line fail If the programmed alarm action is a pip tone, the micro will instruct the DSP to append 200ms burst of 600Hz tone to each transmission (to line and/or radio). Note: Sub-rack alarms (Fwd and Rev Power, Low battery or Line fail) cannot be re-triggered until they are cleared. The 4 external closure alarms however will re-send any user programmed tone sequence if re-triggered when already latched. © Copyright Tait Electronics Limited August 2004. All rights reserved. D2.6 Circuit Operation 2.3.1 Alarm Triggers M8SL2-00-002-812 The alarms are triggered according to their type. Priority Alarm Type Trigger Type Re-triggerable when latched LED colour 1 Auxiliary Input 0 to Input 3 External closure. Sampled every 50ms Yes Green 2 Reverse Power 3 Forward Power Sampled every 50ms while the T803 is keying the transmitter. Incororates a 2s settling time. No Red 4 Low Battery Voltage must be below the programmed threshold for 25s of a 30s period. No Red 5 Line Fail Programmable non-activity time period No Red Table 2.1 Alarm Summary Table External Closure Alarm (Auxiliary Input Alarms) The 8 bit input latch (IC202) is sampled every 50ms. If two successive samples are the same value then the state of the closure alarms is tested (This has the effect of debouncing the alarm inputs). If any alarm is low then those alarms are latched. RF Power Alarm The forward and reverse power alarms are only tested when the T803 is keying the transmitter. The alarms must be active (low) for two seconds before they are latched. The two seconds sampling period allows for settling time inherent in some older T800 PA designs. Note that if a Transmitter fitted with a T1500-52-0000 PCB is being used, rack backplane links LK1 and LK2 must be fitted at power up. Low Battery Alarm The 13.8V supply line voltage is measured by the A/D converter (IC208) every 50ms. If the voltage is below the programmed alarm threshold (±0.05V) for more than 25 seconds of a 30 second sampling period, the alarm is latched. The long sampling period allows for load fluctuation effects on the supply. Programmable low voltage threshold is only available in T803 firmware version 2.11 or later. Prior to this, the threshold was fixed at 10.7V ±0.05V. Line Fail Alarm If no keying from line occurs within the period programmed by the user from PGM800Win, the microprocessor latches this alarm, saves the mode status and puts the T803 into repeater mode. Note that programming zero as the line fail time disables this alarm. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 2.4 Circuit Operation D2.7 Confirmations Additional to alarms the T803 microprocessor also monitors eight non-alarm triggers known as Confirmations: • Power-up • Channel change • Up to six user defined function tone inputs The T803 micro responds to a confirmation trigger in the same way as it does to an alarm trigger – depending on what has been programmed into the EEPROM, a tone sequence may be sent, an auxiliary output enabled and/or a pip tone enabled. These are all actioned by the micro with the same rules as for alarm triggers. The only difference is that there are no LEDs associated with confirmations. If several confirmations are triggered together they are actioned in the following order of priority: Power-up, Channel change and then User Confirmation 0 to 5. If several alarms and confirmations are triggered together the Power-up confirmation, if enabled, is always actioned first, followed by any alarms and then any other confirmations, both in their normal priority order. Note: Confirmations will re-send any user programmed tone sequence if re-triggered. 2.5 Clearing Alarms and Confirmations The alarms can be cleared by either pressing both front panel switches together or sending the T803 a correctly programmed (“Clear Alarms”) function tone. All alarms are cleared together. Clearing alarms turns off all LEDs, cancels any associated pip tones and resets auxiliary outputs. If an alarm condition is still valid when it is cleared, it will be re-latched and the user-programmed action will be executed. If required, pip tones can be cleared separately (leaving alarms latched) by using a “Clear Alarm/Confirmation Pip tones” function tone. When the Line fail alarm is cleared, the T803 will revert to the mode it was in (Basestation or Repeater) before the alarm was triggered. A keying sequence from line can also clear this alarm in the same way except that the pip tone will not be cleared if used by other latched alarms. Line fail is the only alarm that can be cleared individually in this way. Confirmations can not be cleared by a single command like the Alarms. Confirmation pip tones are cancelled by using a “Clear Alarm/Confirmation Pip tones” programmed function tone and the auxiliary outputs are individually reset by using a “Turn OFF Auxiliary output (x)” function tone. It is possible to have more than one Alarm or Confirmation using the pip tone. In this situation the clearing behaviour must be carefully considered: • Line Fail Pip – Cleared by line keying-sequence only if pip tone is not ‘active’ for other Alarms and/or Confirmations. © Copyright Tait Electronics Limited August 2004. All rights reserved. D2.8 Circuit Operation M8SL2-00-002-812 • Alarm Pips (including Line Fail) – Cleared by “Clear Alarms” command only if confirmation pips are not ‘active’. Always cleared by “Clear Alarm/Confirmation Pip tones“ command. • Confirmation Pips – Cleared by “Clear Alarm/Confirmation Pip tones” command. Additionally, it is also possible to have a single auxiliary output assigned to more than one alarm or confirmation. However, be aware that any command that resets auxiliary outputs, such as “Clear Alarms” or “Toggle Auxiliary Output (x)”, will not make any check for multiple use – auxiliary outputs will be reset regardless. 2.6 Voting Tone Operation When the T803 is programmed to generate a tone on idle, the microprocessor monitors the receiver Mute-In signal. When it is high (receiver muted) the DSP is instructed to generate a voting tone to Line-Out. When receiver Mute-In is low the voting tone is turned off. To prevent false detection of the idle tone at the far end voting equipment, the DSP filters energy at the idle tone frequency from the receiver audio transmitted to Line-Out. If the T803 is programmed to generate a Sliding (or Simoco compatible) Voting Tone the microprocessor reads the receiver RSSI level every 6ms using the A/D converter and sends this value to the DSP. The DSP generates a voting tone to Line-Out. The tone frequency is proportional to the RSSI level. To prevent incorrect operation of the far end voting equipment, the DSP low pass filters the receiver audio transmitted to Line-Out. © Copyright Tait Electronics Limited August 2004.

Ground D3.6 Installation and Configuration 3.1.2.1 Auxiliary Alarms Inputs M8SL2-00-002-812 The T803-02 has 4 closure alarm inputs. On every falling edge the associated alarm is (re)triggered, and sent when the T803 becomes idle. Alarm0 has higher priority than Alarm3, in that the alarm will be actioned first. Maximum input voltage = 5V Note: The behaviour is different from the T803-00 as it will resend any user programmed tone sequence if re-triggered when already latched. 3.1.2.2 Auxiliary Control Outputs The 4 Auxiliary outputs are of common collector type (they will only sink current), and are rated to a maximum of 50V and 250mA. The outputs can be controlled via a function tone sequence (Enable, Toggle, or Disable) or enabled on an alarm or confirmation. 3.1.3 Line Interface The following table describes the pin configuration for interfacing with the T803 on 4-wire and 2-wire networks.

Normally this is sufficient, however by shorting JP200 (found on the T803 PCB) an extra 15dB gain is added. © Copyright Tait Electronics Limited August 2004. All rights reserved. Installation and Configuration M8SL2-00-002-812 3.2 D3.7 T803 Configuration Before using the T803, line input (the level from the receiver) and output level (the level presented to the radio transmitter) need to be properly configured. Base Station Audio level from T803 to Tx adjusted using Line Sensitivity control. (for 60% full system deviation) Tx Line In configured using PGM800Win or T803 Test mode. Line in T803 Line out Dispatch Console Line Out configured using PGM800Win or T803 Test mode. Rx Audio level from Rx to T803 adjusted using RV2 on backplane or Line Level control on Rx. (230mVrms) See Section 3.2.4.3. Figure 3.2 T803 setup The Line-In/Line-Out levels can be set up using either the programming application (PGM800Win) or the test modes of the T803 (accessed via the buttons on the front panel. See Section 3.2.3). The advantage of the test mode method is that it can provide a direct test of the system. The programming method is required when access to the dispatch console is difficult. Using the test modes, the T803 levels are set up using actual signals present on the line. For the Line-In level, the test tone and keytone, are generated by the dispatch console and sent to the T803 via the leased line (or an audio generator could be used with the line loss simulated). For the Line-Out level, the test tone is generated by the T803. Programming the Line-In/Line-Out levels using PGM800Win does not require any connection to the line. However, input/output specifications of the dispatch console and actual line loss must be known so that the T803 levels can be properly calculated and programmed. Setting up receiver and transmitter levels can only be done using T803 test modes and/ or measurement. These levels are not programmable. © Copyright Tait Electronics Limited August 2004.

Ensure that transmitter or PA RF output is sufficiently attenuated to prevent damage to the test set. Run up the receiver and transmitter as instructed in Part B and C of this manual. 3.2.2 Use of Test Microphone The T803 test microphone is used to communicate both on air to radios and down the line to dispatch consoles. It plugs into the RJ11 connector on the front panel which doubles as a programming port. It is electrically connected in parallel with the receiver (microphone with receiver audio and PTT button with receiver mute). Most dispatch consoles are equipped with an intercom facility whereby speech can be sent to line without a keytone. This enables the dispatcher to talk to service personnel at the repeater site using the T803’s built in speaker without broadcasting speech to air. The service personnel can talk back to the dispatcher using the T803 test microphone (the PTT must be pressed to gate microphone speech). © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 Installation and Configuration D3.9 Note: If the T803 is in repeater mode, PTT on the test microphone will key-on the transmitter and thus broadcast test speech to air. 3.2.3 Test Modes The T803 has three test modes to assist with setting levels: • Test Tone Mode • Line-In Level Configuration Mode • Line-Out Level Configuration Mode1 To enter the test modes, press the Monitor and Mode Toggle buttons on the front panel simultaneously for three seconds. The alarm LEDs will start flashing colours and travelling up and down the display to indicate Test Tone Mode. The T803 will key-on the transmitter and encode a 1kHz test tone to the transmitter for one minute. The test tone can also be heard on the T803 speaker. While still in Test Tone Mode, simultaneously pressing the Monitor and Mode Toggle buttons briefly will change the mode to Line-In Level Configuration Mode. All the LEDs will be on — either entirely red or entirely green. • Green = Keytone present. T803 will key-on the transmitter. • Red = No keytone present While still in Line-In Level Configuration Mode, simultaneously pressing the Monitor and Mode Toggle buttons again will change the mode to Line-Out Configuration Mode1. To indicate this, all the LEDs will be orange. Note: After entering each mode, a one to two second pause is required before attempting the simultaneous press to enter the next mode (or to exit). While in Line-In or Line-Out Configuration Mode, the Monitor and Mode Toggle buttons operate as ‘gain’ adjust buttons. A short press on the Monitor button will increase the Line-In/Line-Out gain and toggle the top alarm LED on or off, indicating a level increase. The LED will no longer toggle (it will stay on) when the top of the range has been reached. Conversely the Mode Toggle button will decrease the gain and toggle the bottom alarm LED. Again, the LED stays on when the bottom of the range has been reached. In both of these modes Line-In audio can be heard on the monitor speaker. To exit Line-Out Configuration Mode, briefly press both buttons again. Alternatively, the unit will automatically return to normal operation mode after one minute. (This occurs in all three test modes). Note: These levels are always preserved on exit. Take care not to change them unintentionally during simultaneous button press. 1. Line-Out Configuration Mode is only available in T803 firmware version 2.07 or later. For firmware versions prior to 2.07, a simultaneous button press while in Line-In Configuration Mode will exit Test Mode . © Copyright Tait Electronics Limited August 2004. All rights reserved.

Also, ensure that the equipment has been set up correctly as indicated in Section 3.2.1. It is important that the T800 Transmitter output is connected to the Test Set (through an attenuator as required) because it will often be keyed during these level setting procedures. The following levels need to be set: • Tx Audio – Audio level from T803 to transmitter (balanced) • Line-In level • Rx Audio – Audio level from receiver to T803 (unbalanced) • Line-Out level The only consideration of order is that the Tx Audio level needs to be configured before the Line-In level can be done. © Copyright Tait Electronics Limited August 2004.

M8SL2-00-002-812 3.2.4.1 Installation and Configuration D3.11 Tx Audio – Audio Level from T803 to Transmitter The level of audio received from the T803 is adjusted at the input of the transmitter. 1. Set the T803 into Test Tone Mode (See Section 3.2.3) 2. Adjust the Line Sensitivity Control on the front panel of the transmitter to give a reading on the RF Test Set of 60% full system deviation (compensate for any CTCSS tone deviation). Narrow Band Wide Band Channel Spacing 12.5kHz 25kHz Maximum deviation (specifications) 2.5kHz 5kHz 60% of maximum deviation 1.5kHz 3.0kHz 3.2.4.2 Line-In Level The Line-In level can be set up in two ways: • On the T803 in Level Configuration Mode • Using PGM800Win programming software. Using Level Configuration Mode: Note: The Tx audio level must be set up before starting this procedure (Section 3.2.4.1). 1. Set the T803 into Line-In Level Configuration Mode (See Section 3.2.3). 2. Connect a dispatch console to the far end of the line, or simulate the console and line loss using an audio generator. 3. Press the PTT on the dispatch console. This will send a keytone to the T803. Ensure the console also sends a test tone at speech level to line (this tone is required for this method of configuring the Line-In level). 4. The alarm LEDs on the front panel of the T803 should change to green (indicating that a keytone has been detected) for as long as the PTT is pressed. 5. Adjust the Line-In level by pressing the Monitor button (increases the level) or the Mode Toggle button (decreases the level) until the transmitter deviation reading, monitored on the RF Test Set, indicates 60% full system deviation (compensate for any CTCSS tone deviation). 6. Press the PTT on the dispatch console again, but this time use speech instead of the test tone. Ensure the LEDs on the T803 remain constant on green during speech transmission. If not see Section 3.3.1 (point 7) on how to troubleshoot for Talkoff. © Copyright Tait Electronics Limited August 2004. All rights reserved. D3.12 Installation and Configuration Note: The monitor speaker is forced on in this mode so that the test-microphone may be used as an intercom to communicate to the dispatcher room (See Section 3.2.2). M8SL2-00-002-812 Using PGM800 software: 1. Determine the output level of the console. This may be a preset or default value specified in the console’s manual or a value programmed by the operator. 2. Determine the actual line-loss between the console and the T803. 3. Calculate T803 Line-In Level as follows: T803 Line-In Level = console output level (dBm) – Line-loss (dB) 4. Program the T803 with the calculated level. Example case: Console output level =–13dBm Measured Line loss = 6.5dBm T803 Line-In level =–13 – 6.5 = –19.5dBm 3.2.4.3 Rx Audio – Audio Level from Receiver to T803 The Rx Audio level is adjusted using either the Line Level control on the front of the receiver or the RV2 potentiometer on the backplane, depending on the configuration of the link LN8 on the backplane. The recommended (and default) configuration of LN8 is with pins 2–3 and 4–5 linked. With this configuration the balanced audio from the receiver (Rx-Line-1 and RxLine-4 ) is changed to unbalanced audio for the T803 (this means the Rx Line output can no longer be used as direct balanced audio to the transmitter). The level to the T803 is adjusted using the Line Level control on the front of the receiver. The advantage of using this path is that it allows CTCSS filtering to be applied (using the receiver’s internal CTCSS filter. See Section 3.5 in Part B). Alternatively if CTCSS is not used, the receiver unbalanced audio output (Rx-Audio-1) can be used to provide audio to the T803 by linking pins 1–2 on LN8. In this case the level to the T803 is adjusted using the RV2 potentiometer on the backplane. This audio path is not suitable for CTCSS systems because complete CTCSS filtering cannot be applied. The only filtering directly available is the optional receiver de-emphasis filtering. See Section 3.5 in Part B. The T803 does however apply a 160Hz to 3kHz high pass filter resulting in an overall audio response for this path very similar to the default high pass filtered receiver balanced Line output. See the table below. © Copyright Tait Electronics Limited August 2004. All rights reserved. Installation and Configuration M8SL2-00-002-812 Receiver/T803 system D3.13 Backplane links (LN8) Adjustment of Rx Audio to T803 With CTCSS on Rx audio Link pins 2–3 and pins 4–5 Line Level control on the front of the Receiver Receiver internal CTCSS filter should be included in the path (see Section 3.5 in Part B) 400Hz to 3kHz No CTCSS on Rx audio Link pins 2–3 and pins 4–5 Line Level control on the front of the receiver Receiver internal CTCSS filter not in path but high pass filter in path (Rx default setup) 220Hz to 3kHz No CTCSS on Rx audio Link pins 1–2 RV2 on the backplane T803 high pass filter only 160Hz to 3kHz Audio Frequency Response The table above shows that configuring LN8 with links 2–3 and 4–5 could be used for systems with or without CTCSS. Configuring LN8 with link 1–2 in normally only used with systems without CTCSS on the Rx audio. Procedure Before commencing this procedure set up the receiver audio processing, such as deemphasis and CTCSS filtering, as required for the application. See Section 3.5 in Part B. This is important for the T803 Telecom line compliance. See the Caution below. CAUTION: The Rx audio level must not exceed 230mVrms at 60% full system deviation. This will ensure that the actual T803 Line-Out level corresponds to the programmed value and thus ensures levels do not exceed the power level requirements of the Telecommunications line. There are three possible ways to monitor the Rx Audio level during adjustment: • Direct measurement of receiver audio on the backplane • Indirectly, using transmitter deviation • Indirectly, using the T803 Line-Out level Direct measurement of receiver audio on the backplane: 1. Use the RF Test Set to generate an on-channel signal to un-mute the receiver. 2. Modulate the RF carrier with a 1020Hz tone1 at 60% full system deviation, adding CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the receiver as required for the application. See Section 3.5 in Part B). 3. Monitor the audio level from the receiver on the X800-56-PCB3 backplane at pin2 of LN8, with the links (jumpers) in place as directed in Section 3.1.1. Use a high impedance meter such as an oscilloscope for the measurement. 1. A 1020Hz tone is used (rather than 1kHz) because some Test Sets can produce unstable deviation readings © Copyright Tait Electronics Limited August 2004. All rights reserved. D3.14 4. Installation and Configuration M8SL2-00-002-812 For LN8 with pins 2–3 and 4–5 linked, adjust the line level control on the front of the receiver for an audio level of 230mVrms. For LN8 with pins 1–2 linked, adjust RV2 on the backplane for an audio level of 230mVrms. Using transmitter deviation: This method is not suitable for simplex configured repeaters. 1. Use the RF Test Set to generate an on-channel signal to un-mute the receiver. 2. Modulate the RF carrier with a 1020Hz tone1 at 60% full system deviation, adding CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the receiver as required for the actual working system. See Section 3.5 in Part B). 3. Put the T803 unit into Talk Through Mode (also known as Repeater Mode) using the Mode Toggle button1. The Mode LED should be red, constant or flashing, and the transmitter should be keyed on. 4. For LN8 with pins 2–3 and 4–5 linked, adjust the Line Level control on the front of the receiver to produce 60% full system deviation at the transmitter RF output as measured on the test set. 5. For LN8 with pins 1–2 linked, adjust RV2 on the backplane to produce 60% full system deviation at the transmitter RF output as measured on the test set. Note: De-Emphasis should be off on the test set receiver. Using the T803 Line-Out level: 1. Use the RF test set to generate an on-channel signal to un-mute the receiver. 2. Modulate the RF carrier with a 1020Hz tone2 at 60% full system deviation, adding CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the receiver as required for the actual working system. See Section 3.5 in Part B). 3. Put the T803 into Base Station Mode using the Mode Toggle button1. The Mode LED should be green (constant or flashing). 4. For LN8 with pins 2–3 and 4–5 linked, monitor the T803 Line-Out level (600Ω balanced audio) and by adjusting the Line Level control on the front of the receiver, set this level to equal the programmed ‘Line-Out Level’ as set in PGM800Win. For LN8 with pins 1–2 linked, monitor the T803 Line-Out level (600Ω balanced audio) and by adjusting RV2 on the backplane, set this level to equal the programmed ‘Line-Out Level’ as set in PGM800Win. 1. The Mode Toggle button may be disabled from PGM800Win 2. A 1020Hz tone is used (rather than 1kHz) because some Test Sets can produce unstable deviation readings © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 3.2.4.4 Installation and Configuration D3.15 Line-Out Level The Line-Out Level can be set up in two ways: • On the T803 in Level Configuration Mode • Using PGM800Win programming software (version 4.02 or later). Using Level Configuration Mode (T803 firmware version 2.07 or later): 1. Set the T803 into Line-Out Level Configuration Mode (See Section 3.2.3). 2. Use the RF Test Set to generate an on-channel signal to un-mute the receiver. 3. Modulate the RF carrier with a 1020Hz tone at 60% full system deviation, adding CTCSS tone if necessary (ensure that CTCSS tone is removed from the receiver audio output by selecting the correct links inside the receiver). 4. Monitor the T803 Line-Out level and adjust by pressing the Monitor button (increases the level) or the Mode Toggle button (decreases the level) until the level is acceptable at the dispatch console. Note: The monitor speaker is forced on in this mode so the test-microphone may be used as an intercom to communicate to the dispatcher room (See Section 3.2.2). Using PGM800Win software: 1. Determine the input level required at the dispatch console. This may be a preset or default value specified in the console’s manual or a value programmed by the operator. 2. Determine the actual line-loss between the console and the T803. 3. Calculate T803 Line-Out Level as follows: T803 Line-Out Level = console input level (dBm) + Line-loss (dB) 4. Program the T803 with the calculated level. Example case: Console input level = –13dBm Measured Line loss = 6.5dBm T803 Line-Out level = –13 + 6.5 = –6.5dBm 3.3 1. Fault Finding Connect the T803 to its companion dispatch console via the leased line. Check that speech sent from the console can be heard on the T803 speaker (un-mute speaker if required). © Copyright Tait Electronics Limited August 2004. All rights reserved. D3.16 Installation and Configuration M8SL2-00-002-812 One possible cause of incorrect operation is that the line connections have become transposed in the wiring network or that the dispatch terminal uses different Send/Receive pairs. 2. Use the dispatch console to key-on the transmitter. If the transmitter does not keyon, check that the console and T803 have been compatibly programmed. • check 2-wire or 4-wire • check the keytone frequency • check if function tones are used • check high level guard tone and function tone periods (if used) are the same Finally check that the console is sending appropriate signal levels and that tone durations are correct (which are often variable), and that the line is not causing unacceptable attenuation or distortion. 3. If the console can key the transmitter but not change Repeater/Basestation Mode, auxiliary outputs, receiver defeat or cancel alarms, carry out the checks in Step 2 above, but pay particular attention to the function tone programming. If changing channels is a problem check that the appropriate channel selection DIP switches (SW1) on the rack backplane are off. 3.3.1 1. Troubleshooting Sometimes misses function tone command Set up the Line-In level so that the function tones are about 2Vpp at TP204. 2. Misses function tone sequence on very fast key repetition A minimum of 200ms pause is required between pressing buttons on the console. Some consoles do not limit the maximum keying rate. 3. PGM800Win: “Warning: the Firmware version is not compatible. Data read maybe incorrect” This warning occurs when reading the T803 with an old version of PGM800Win. This can be ignored as the T803 unit is backwards compatible. However, it is recommended to use the latest PGM800Win with full T803 support. 4. Loop-Line functionality (also known as Loopback) Loopback can be enabled in PGM800Win. It is then activated by sending the T803 the programmed function tones. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 5. Installation and Configuration D3.17 While in Line-In Level Configuration Mode, the LEDs flash green only briefly when the dispatch console PTT is pressed The Line-In level is too low. The T803 is only detecting the high-level guard tone (HLGT). While still in Line-In Level Configuration Mode, activate the console PTT and adjust the Line-In level by pressing the Monitor button (increases the Line-In level) until the LEDs remain constant green. The top alarm LED will toggle on and off, indicating a level increase until the top of the range is reached (may be as many as 65 presses). If this still fails, open up the unit and add JP200, and try again. 6. When the PTT is pressed, a pulsing sound can be heard from the speaker The Line-In level is too high. The function tones can not be decoded properly hence it keys off. While still in Line-In Level Configuration Mode, activate the console PTT and adjust the Line-In level by pressing the Mode button. The bottom alarm LED will toggle on and off, indicating a level decrease until the bottom of the range is reached. Using an oscilloscope measure the signal on TP204 – the function tone level should be about half the level of the high level guard tone. 7. The console keys the transmitter correctly except when speech is present This is known as ‘Talkoff’ and occurs when the difference between the keytone level and speech peak level exceeds specification (32dB in 2-wire mode and 35dB in 4-wire mode), causing the keytone detection to fail. For reliable operation, the keytone level should be no more than 35dB lower than peak speech level. If it is not possible to adjust the levels at the console, decrease the programmed Line-In level of the T803 until talkoff is eliminated. This requires that the audio level from T803 to transmitter will also need to be re-adjusted (using the transmitter’s Line Sensitivity control) to maintain 60% full system deviation for the test tone sent from the console. Adjust the relative audio levels (keytone and speech) sent from the dispatch console. 8. Keytone Falsing in 2-wire mode When operating in 2-wire mode with lossy lines (i.e. significant separation required between T803 Line-In and Line-Out levels) the keytone detector can become de-sensitised by noise. • Check to ensure that the input level from the receiver is correctly set up at 230mVrms (See Section 3.2.4.3). • Check the receiver mute open level (squelch). If necessary adjust the receiver Gating Sensitivity control on the front panel of the receiver, so that the receiver mute opens at a higher SINAD level (12dB or preferably greater). This has the effect of reducing the noise on the line input of the T803 in 2-wire mode. © Copyright Tait Electronics Limited August 2004. All rights reserved. D3.18 • Installation and Configuration M8SL2-00-002-812 If there is still a problem after the squelch gating level has been adjusted as much as practicable, it becomes necessary to reduce the separation between the T803 Line-In and Line-Out levels. This separation may need to be reduced to less than 8dB for 12dB receiver audio SINAD (or less then 12dB for 14dB receiver audio SINAD). To achieve this, adjust the relative input and output levels of the dispatch console. Again, this has the effect of reducing the noise on the line input of the T803. If the above solutions do not help resolve the problem, the 2-wire line loss may be too severe and unacceptable for normal 2-wire T803 operation. In this case an external hardware solution involving a notch filter fitted to the receiver audio path (TA1086-01) and a 2-wire/4-wire hybrid fitted across the line may be required. This solution has been verified and documentation is available detailing how to install the TA1086-01.

T803 PCB Information M8SL2-00-002-812 4.1 D4.1.3 Introduction PCB Identification All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. Parts Lists The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference lists components in alphanumeric order variant column indicates that this is a variant component which is fitted only to the product type listed description gives a brief description of the component Internal Part Number order the component by this number The mechanical and miscellaneous section lists the variant and common parts in IPN order. © Copyright Tait Electronics Limited August 2004.

D4.1.4 T803 PCB Information M8SL2-00-002-812 Grid Reference Index This section contains a component grid reference index to help you find components and labelled pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alphanumeric order, along with the appropriate alphanumeric grid references, as shown below: PCB layout reference circuit diagram reference components listed in alphanumeric order component location on the sheet sheet number component location on the layer layer number 1 = top side layer 2 = bottom side layer Using CAD Circuit Diagrams Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets. When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g. 1R3).

There is a detailed table of contents at the start of Section 2. Section Title 1 Introduction 2 T850 VCO PCB © Copyright Tait Electronics Limited August 2004. All rights reserved. IPN Page 1.1 220-01145-07 2.1 EII M8SL2-00-002-812 © Copyright Tait Electronics Limited August 2004. All rights reserved. Introduction M8SL2-00-002-812 1 E1.1 Introduction PCB Identification All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. Parts Lists The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference lists components in alphanumeric order variant column indicates that this is a variant component which is fitted only to the product type listed description gives a brief description of the component Internal Part Number order the component by this number The mechanical and miscellaneous section lists the variant and common parts in IPN order. © Copyright Tait Electronics Limited August 2004. All rights reserved. E1.2 Introduction M8SL2-00-002-812 Variant Components A variant component is one that has the same circuit reference but different value or specification in different product types. Variant components have a character prefix, such as “&”, “=” or “#”, before the circuit reference (e.g. &R100). © Copyright Tait Electronics Limited August 2004. All rights reserved.

M8SL2-00-002-812 Power Supply Description 2 Power Supply Description 2.1 Introduction F2.1 The T800-23-0011 power supply consists of a Power Supply Unit (PSU) Module, connectors, and ferrite filters. These components are shown in Figure 2.1 below. Feed through loom from programming port and speaker on SL2 front panel to back plane PCB. PSU Module Ferrite Bead (Mains Input filter) Ferrite Bead (Mains Ground filter) Chassis grounding point using Earth Tag IEC Plug (Mains Input) Internal Loom Ferrite Sleeve (DC Output filter) Molex Socket (DC Output) Figure 2.1 T800-23-0011 internal view. See the Parts List in Section 6.2.2 for more detail. © Copyright Tait Electronics Limited August 2004. All rights reserved. F2.2 Power Supply Description 2.1.1 PSU Module M8SL2-00-002-812 The PSU module used in the T800-23-0011 power supply has over temperature, current overload and overvoltage protection. Refer to Section 1.2 for specification details. Overvoltage applied on the module’s output will cause the module to shutdown. To reset the module, remove the mains supply to the T800-23-0011, allow 30 seconds for charges to leak away, and then reconnect the T800-23-0011. The module is protected from current overload by a voltage foldback method. If the load on the output starts drawing more current than the specified maximum, the voltage will start dropping away. This condition will recover automatically when the load is removed or returns to normal. Over temperature will cause the module to shutdown. It will recover automatically when it has cooled down to an acceptable operational temperature. Caution: Correct mounting of the T800-23-0011 power supply is important: Refer to Section 3.3 for ventilation guidelines. Ignoring these conditions may cause the module to overheat, and consequently, to shut down. 2.1.2 Internal Loom Mains power to the PSU module is supplied via an IEC plug on the rear panel and then filtered by a ferrite bead (shown in Figure 2.1). The mains ground line is filtered by a ferrite bead and then connected to the T800-23-0011 chassis and to the PSU module’s floating ground contact. The PSU module’s output is filtered by a ferrite sleeve on the positive line, and then interfaces to the SL2 backplane via a Molex connector on the T800-23-0011 rear panel. Additionally a ‘feed-through’ loom is connected to the Molex connector. This loom forms part of the path for the programming and speaker connection between the SL2 backplane and the SL2 front panel. The external cable connection between the T800-23-0011 and the SL2 backplane completes this path. For the wiring diagram, refer to Section 6.2.1. © Copyright Tait Electronics Limited August 2004.

Installation Guidelines M8SL2-00-002-812 3 F3.1 Installation Guidelines The following section gives a brief description of the basic rack mounting and wiring procedures. 3.1 General The T800-23-0011 is supplied mounted to the SL2 front panel by four M3x10 button hex screws. A small cable extending out of the front of the T800-23-0011 plugs onto to the SL2 front panel. This cable forms part of the programming and speaker connection between the SL2 front panel and the backplane. The external cable connection between the T800-23-0011 and the SL2 backplane provides the DC power supply to the basestation and also incorporates 3 wires completing the programming and speaker connection. Warning: FUSE The cable connecting the T800-23-0011 DC power output to the backplane also includes a fuse. This fuse is critical to the IEC 60950 safety compliance of the T800 SL2 Base Station and must be replaced with the same component or compliance will be voided. The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A (60VAC) For the AC mains input connection of the T800-23-0011 use only an IEC type detachable power supply cord (with a moulded IEC connector). Ensure that it has a current rating of at least 5A. 3.2 Connector Pinouts The pinouts for the AC mains input connector and the DC output connector on the rear of the T800-23-0011 are shown in Figure 3.1 below.

F3.2 Installation Guidelines 3.3 Equipment Cooling M8SL2-00-002-812 Although the T800-23-0011 is a high efficiency switching power supply, a considerable amount of heat is generated during normal operation. An adequate flow of cooling air is therefore essential for reliable operation. Caution: Do not operate this unit in a completely enclosed cabinet. It is estimated that the average life expectancy of this unit will double with every 10°C drop in ambient temperature. It is therefore recommended to: • Keep the ambient temperature low. • Ensure that airflow is not restricted. © Copyright Tait Electronics Limited August 2004. All rights reserved.

Refer to Figure 4.1 for test equipment details. Oscilloscope Isolating Transformer 1kVA Mains Supply Earth Leakage Circuit Breaker DC Load 0 to 30ADC Variac 0 to 260VAC 1kVA V _ A _* Output AC Input + - V _ A _ * True RMS Reading T800-23-0011 PSU Figure 4.1 Test equipment setup 4.1 Basic Operation To confirm the basic operation of the power supply, proceed as follows. • Ensure that the main supply to the T800-23-0011 is switched off. Set up the test equipment as shown in Figure 4.1. • Set the output DC load to maximum resistance/minimum current. • Connect the T800-23-0011 to the mains supply and switch it on. • Vary the DC load and check that the output voltage and current are within the specifications (refer to Section 1.2.4). 4.2 Output Current Overload To confirm the operation of the current overload protection circuitry, proceed as follows. • Ensure that the main supply to the T800-23-0011 is switched off. Set up the test equipment as shown in Figure 4.1. • Set the output DC load to draw approximately 11A. • Switch on the mains supply and slowly decrease the load resistance, thereby increasing the current until voltage foldback occurs. The current should not rise above the Current Overload Limit (refer to Section 1.2.4), but voltage should drop away. © Copyright Tait Electronics Limited August 2004. All rights reserved. F4.2 Functional Testing 4.3 Output Noise M8SL2-00-002-812 To check that output noise is within specification, proceed as follows. • Ensure that the main supply to the T800-23-0011 is switched off. Set up the test equipment as shown in Figure 4.1. Connect the T800-23-0011 to the mains supply and switch it on. • Connect a digital voltmeter (e.g. Fluke 77) across the load terminals and set the meter to its lowest AC volts range. • Check that the reading is less than 100mVpp under all load and line conditions. Note: A real reading of the level of noise present on the output of a switching power supply is very difficult to obtain, as low noise levels, common mode noise paths and ground loops all lead to inaccurate measurement results. The procedure outlined above will, however, give a good indication of the output noise. 4.4 Overall Power Supply Stability To check for overall PSU stability, proceed as follows. • Ensure that the main supply to the T800-23-0011 is switched off. Set up the test equipment as shown in Figure 4.1. Connect the T800-23-0011 to the mains supply and switch it on. • Connect the oscilloscope across the output. • Vary the mains voltage and DC load over the full specified range (refer to Section 1.2). • Check on the oscilloscope that no oscillations occur. © Copyright Tait Electronics Limited August 2004.

All that is required is for the connection of suitable cables. 1.3 Power Supply The power rating information for the T800SL2 with the Tait supplied power supply module (T800-23-0011), is provided on the label located on the top cover as visible in Figures 1.6. The power rating information for the T800SL2 for use with a customer supplied DC power source, is provided on the label located on the top rear of the Transmitter module. In order to comply with the safety requirements of EN60950, the power supply module used with the T800SL2 must be provided with an easily accessible mains disconnect device compliant with IEC61058, such as a switch or circuit breaker. This provides the means to rapidly disconnect the mains power in an emergency. All Tait supplied racks incorporate a power distribution board with a circuit breaker easily accessible in the back of the rack, on the lower right hand side (viewed from the rear). The circuit breaker will disconnect the mains to the entire rack. If only one channel needs to be mains-isolated and the Tait power supply module is T800-23-0011, then it is acceptable practice to pull the IEC connector directly out of the power supply module. If a customer supplied power source is used, it must have the following features: • An easily accessible and safety compliant mains disconnect device. • The capability to provide enough current to drive the T800 system. • Free from excessive ripple or noise. • Meets all EMC and safety regulations for the intended market. © Copyright Tait Electronics Limited August 2004. All rights reserved. G1.2 M8SL2-00-002-812 The entire system should be protected by the use of appropriately rated fuses in the power supply. Note: It is particularly important when the prime power source is a battery that fuses be employed in all the supply lines. Warning: 1.4 Fuse – DC powered Base Stations The cable supplied for connecting a DC power source such as a battery to the backplane of the SL2 Base Station, includes a fuse. This fuse is critical to the IEC 60950 safety compliance of the T800 SL2 Base Station and must be used or compliance will be voided. If the fuse has blown it must be replaced with the same component The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A (60VAC) Reverse Polarity and Overvoltage Protection A crowbar diode is fitted to all T854 transmitters for protection against connection to a power supply of incorrect polarity. It also provides overvoltage protection from voltage transients caused by lightning strikes. Note: A fuse must be fitted in the power supply line for the diode to provide effective protection. © Copyright Tait Electronics Limited August 2004. All rights reserved.

G1.5 M8SL2-00-002-812 1.6 RF Coax Cable and N-Type Connector Make sure the RF coax cable to the N-type connector is free from sharp bends or twists. If access to the rear of the rack frame is restricted, the cable should be long enough to allow the slimline assembly to be fully withdrawn from the cabinet. Make sure that any N-type plugs connected to Tait equipment are assembled according to the manufacturer’s instructions. It is particularly important that the centre pin in the plug is positioned correctly: • if the pin is positioned too far back in the plug, it may not make good contact with the socket; • if the pin protrudes too far (as shown in Figure 1.5), or is not straight, it may damage the socket when the plug is screwed in.

The default option is %T210B, SMD P2781 or similar 600:600 non centre-tapped SMD encapsulated Line transformer. %T210A and %T210B use a standard footprint which allows the use of other similar transformers with special characteristics, such as the ETAL P3181 ultra-low distortion V.90 SMD. © Copyright Tait Electronics Limited August 2004. All rights reserved. T854 Optional Features M8SL2-00-002-812 G2.3 The line transformer is designed to provide a balanced interface to 600Ω lines, connected between LINE I/P 1 and LINE I/P 4. When %T210 is fitted, the two centre connections (LINE I/P 2 and LINE I/P 3) are shorted together for normal operation. With the other options these two centre connections are available to the user via P204 and P208, unless a centre-tapped %T210A or %T210B is used, wired to LINE I/P 3. The secondary winding of the transformer is connected via 1kΩ (R202) and 10Ω (R160) resistors to pin 6 (AUDIO-2) of D-range 1 and may be used to monitor audio on the line. Pin 7 of D-range 1 can be reconfigured as AUDIO-1 by removing R808 and R160, and placing %R150.

Talk Through Repeater M8SL2-00-002-812 3 G3.1 Talk Through Repeater In this configuration the receiver directly keys the transmitter when the signal is received. The demodulated audio is fed via 600Ω lines to the transmitter to modulate the carrier. The receiver and transmitter operate simultaneously and must therefore be on different frequencies. The minimum frequency separation depends on the duplexer used.

Line Controlled Base without Talk Through M8SL2-00-002-812 4 Line Controlled Base without Talk Through 4.11 General G4.1 This installation contains a transmitter and receiver which may or may not be on the same frequency, thus simultaneous transmission and reception is not possible. When the transmitter is keyed, the coaxial relay is also energised. When the relay is in its rest position, signals from the antenna are passed to the receiver and the demodulated output is fed via 600Ω lines to the RCU. The receiver is disabled when the transmitter is energised to prevent the receiver mute opening from RF due to lack of isolation in the relay, direct radiation or the noise skirt of the dual frequency link. Since the base station may be controlled via a 2-wire line and a 4-wire to 2-wire hybrid, there is a possibility of system oscillation if the receiver is not disabled during transmit. This occurs when the transmit energy enters the receiver and produces an audio response which can pass from the receive to the transmit audio part of the hybrid (impedance imbalance, etc).

Rx Off Rx Disable Time No Tx or Rx Tail Time Figure 4.5 Receiver Disable Time vs Tail Time • if the system configuration also uses an aerial changeover relay as well as the tail timer, the changeover relay must be driven from the relay driver (Q250) in the audio processor, rather than by Tx-Key or Tx-Enable; this output is available on pin 9 of the T800-03-000 auxiliary D-range (D-range 2); • depending on tail time requirements, it is possible for the transmitter tail time to exceed the receiver disable time capability; in this situation the receiver disable line should also be driven from relay driver Q250 (D-range 2 pin 9). © Copyright Tait Electronics Limited August 2004.

DC Line Keying M8SL2-00-002-812 5 G5.1 DC Line Keying Where the transmitter and receiver are separated by only a short distance and DC isolation is not required, DC loop keying may be employed. This feature is not available with standard line transformer ETAL P2781 (%T201B). Refer to Section 2.2. Note: A small DC current (usually less than 10mA) can be fed via the balanced 2-wire line to provide remote control of various functions. In a duplex system the receiver mute is used to key a transmitter, provided there is a common earth between the two units (refer to Figure 5.6).

X800-56-PCB3 PCB Information M8SL2-00-002-812 6.1 G6.1.3 Introduction PCB Identification All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which is screen printed onto the PCB (usually on the top side), as shown in the example below: The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Note: It is important that you identify which issue PCB you are working on so that you can refer to the appropriate set of PCB information. Parts Lists The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can process your spare parts orders more efficiently and accurately if you quote the IPN and provide a brief description of the part. The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below: circuit reference lists components in alphanumeric order variant column indicates that this is a variant component which is fitted only to the product type listed description gives a brief description of the component Internal Part Number order the component by this number The mechanical and miscellaneous section lists the variant and common parts in IPN order. © Copyright Tait Electronics Limited August 2004.

G6.1.4 X800-56-PCB3 PCB Information M8SL2-00-002-812 Grid Reference Index This section contains a component grid reference index to help you find components and labelled pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alphanumeric order, along with the appropriate alphanumeric grid references, as shown below: PCB layout reference circuit diagram reference components listed in alphanumeric order component location on the sheet sheet number component location on the layer layer number 1 = top side layer 2 = bottom side layer Using CAD Circuit Diagrams Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets. When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g. 1R3).

M8SL2-00-002-812 T800 Ancillary Equipment 1 T800 Ancillary Equipment 1.1 Programming Kits H1.1 T800-01-0000 The T800-01-0000 kit is used for programming T800 SL2 base station equipment using a standard IBM (or compatible) PC. The kit comprises the following items: PGM800Win programming software user's manual PGM800Win Windows based programming software on CD T800-01-0002 programming cable. T800-01-0001 The T800-01-0001 kit is the same as the T800-01-0000 kit described above, but with the addition of the T800-01-0004 module programming interface. T800-01-0002 The T800-01-0002 programming cable connects the PC directly to the programming socket on the T800 SL2 rack frame speaker panel or backplane PCB, thus enabling T800 SL2 modules to be read or programmed while in the rack frame. It can also connect to the programming socket on the T800-01-0004 programming module interface if the module is to be read or programmed while out of the rack frame. T800-01-0003 The T800-01-0003 programming kit contains a T800-01-0002 programming cable and a T800-01-0004 programming module interface. T800-01-0004 The T800-01-0004 programming module interface is designed to allow a PC to connect directly to a T800 SL2 module. It comprises a small PCB on which is mounted a D-range socket, a programming socket, a Micromatch socket and a DC input connector. The T800-01-0004 plugs directly into D-range 1 or D-range 2 (selected by a switch on the PCB), or into SK805 in the microcontroller compartment via the supplied ribbon cable loom, and is then connected to the PC with a T800-01-0002 programming cable. Refer to the T800 Ancillary Equipment Service Manual for more information. © Copyright Tait Electronics Limited August 2004. All rights reserved. H1.1.2 T800 Ancillary Equipment 1.2 General Ancillaries M8SL2-00-002-812 T800-09-0001 RF Coaxial Relay The T800-09-0001 is an RF coaxial relay assembly fitted with three female N-type connectors, and comes complete with a mounting bracket and two coaxial cables terminated in male N-type connectors. It can be used, for example, in base station applications where the receiver and transmitter share the same antenna, in which case it can be driven by the T800 SL2 transmitter relay driver (refer to Section 2.4 in Part G for more information). T800-01-0010 Calibration Test Unit The T800-01-0010 provides all inputs and outputs necessary to carry out the full tuning and adjustment procedure for T800 Series I and II receivers, exciters and transmitters. It provides a convenient method of connecting test equipment, including a PC and power supply, to a T800 Series I or II module (via D-range 1) without the need to construct custom wiring looms. The T800-01-0010 also has a built-in speaker, a switch for selecting Series I or II modules, and uses standard BNC and “banana plug” sockets. T800-03 Auxiliary D-Range The T800-03 is an additional D-range kit comprising one D-range plug assembly and two locating pins, nuts and washers. Although originally a T800 Series I ancillary, it can be used in T800 SL2 products for special applications requiring custom internal wiring. T800-03-0000 Auxiliary D-Range The T800-03-0000 is an additional D-range kit (normally fitted as D-range 2) comprising one D-range plug assembly complete with connecting loom and mounting screws. The ribbon cable loom connects the D-range PCB to the Micromatch socket (SK805) in the microcontroller compartment. Typical uses of the T800-03-0000 are in paging applications and where external channel control is required. Refer to Figure 1.4 in Part G for the T800-03-0000 pin connections. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 T800 Ancillary Equipment H1.3 T800-04-0000 RSSI The T800-04 RSSI option PCB plugs directly into the main PCB (support circuitry being fitted as standard). It is fitted to the T855, T875 and T885 whenever receiver signal strength monitoring is required, e.g. trunking or voting. Its function is to provide a DC voltage proportional to the signal level at the receiver input. T800-10-0000 Channel Select PCB The T800-10-0000 is a small PCB that plugs into the Micromatch connector (SK805) in the microcontroller compartment of a T800 SL2 receiver, exciter or transmitter. It is fitted with an eight-switch DIP switch which allows the manual selection of any one of the channels already programmed into the module by PGM800Win. The T800-10-0000 is also fitted with a Micromatch socket to provide access to SK805 for programming purposes. T800-80-0000 Local Microphone A 600Ω microphone complete with 300mm cord terminated in a ¼” stereo plug for use with the T854. T800-80-0001 T803 Microphone A 600Ω microphone complete with 300mm cord terminated with a RJ11connector for use with the T803. © Copyright Tait Electronics Limited August 2004. All rights reserved. H1.1.4 T800 Ancillary Equipment 1.3 Paging M8SL2-00-002-812 T800-30-0000 and T800-30-0002 DFSK Modulators The T800-30-0000 (formerly T800-30) and T800-30-0002 (formerly T800-35) are DFSK modulators for T800 SL2 transmitters, suitable for POCSAG or similar paging data formats. Analogue transmissions (e.g. tone or speech) are still possible by disabling the data path via a control line. 512 or 1200 baud data rates are link selectable. The T800-30-0002 is adapted for use with an external reference oscillator for simulcast transmission. The T800-30-0000 and T800-30-0002 are not designed for use with 66 to 88MHz equipment. T800-32-0000 and T800-32-0010 DFSK Modulators The T800-32-0000 and T800-32-0010 are DFSK modulator PCBs which can be fitted to T800 SL2 transmitters to enable them to function as low-speed paging transmitters. These new PCBs have been specifically designed for Series II transmitters and are much easier to fit into the latest design transmitters. Both PCBs are suitable for POCSAG or similar paging data formats, but are not designed for analogue transmissions (e.g. tone or speech). The T800-32-0010 is adapted for use with an external reference oscillator for simulcast transmission. The T800-32-0000 and T800-32-0010 are not designed for use with 66 to 88MHz equipment. © Copyright Tait Electronics Limited August 2004. All rights reserved. M8SL2-00-002-812 1.4 T800 Ancillary Equipment H1.5 External Frequency Reference T800-06-0000 External Frequency Reference Kit The T800-06-0000 kit provides an additional D-range plug/PCB assembly which incorporates a miniature RF connector to carry an externally generated 12.8MHz reference signal into a T800 SL2 module. This enables the use of very high stability external reference oscillators for special applications. The D-range PCB is also fitted with a Micromatch socket which can be connected to SK805 in the microcontroller section via the supplied loom to provide access to the channel change lines. The kit comes complete with fitting instructions and all installation hardware. T800-06-0001 External Frequency Reference Kit The T800-06-0001 is the same as the T800-06-0000 kit with the addition of a special coax cable for external frequency reference input. One end of this coax is terminated with a miniature RF connector which fits into the D-range socket in an appropriate backplane PCB to connect to a T800 SL2 module fitted with a T800-06-0000 kit. The other end is terminated with a BNC connector which can be mounted on the rack frame. T801-00 Frequency Reference Module The T801-00 frequency reference module provides a high stability frequency source to which the synthesiser within a T800 SL2 base station can be locked. The master standard within the T801-00 is primarily intended to be rubidium, although high quality ovenised crystal oscillators can also be used in applications where more frequent readjustment of frequency is acceptable. The T801-00 converts the output frequency from its master standard to the 12.8MHz required by the T800 SL2 base station. Refer to M801-00. T801-10 OCXO Module The T801-10 OCXO module provides a high stability frequency source to which the synthesiser within a T800 SL2 base station can be locked. This will provide T800 SL2 transmitters with the frequency stability required for simulcast transmission. The master standard within the T801-10 is a high quality ovenised crystal oscillator (OCXO). Three outputs are provided on the rear panel, which allows up to three T800 SL2 transmitters to be referenced to the source oscillator. Refer to M801-10. © Copyright Tait Electronics Limited August 2004. All rights reserved.
