120 20191-002 Paragon-III Technical Manual 8 2.5 Electrical Standard 120 VAC electrical power is required. It should be capable of providing at least 10A to power Paragon-III (<6A) and ancillary equipment. 2.5.1 Paragon-III Assembly Power Two distinct power configurations (rear views) are shown in the preceding pages. They are: • Paragon-III Base Station Standard Assy (Figure 3). This configuration is described in paragraph 2.5.1.1 below. • Paragon-III Base Station Assy. with 3rd party DC supply (Figure 4). This configuration illustrates typical wiring variation required when using both a third-party power supply and an optional DC-powered BDLC-III setup. Refer to Dataradio System Engineering for further details. 2.5.1.1 Standard Power Supply Configuration The Radio assembly unit receives separate 13.8 VDC power inputs from a “T800 Slimline” dual power supply typically rack-mounted right below the main assembly radio chassis. The T800 is made up of two separate power supply units joined in a single chassis (the second one is used as a spare): • A T807 using convection cooling is rated to 15A nominal at 13.8VDC. It supplies all the radio modules other than the Power Amplifier. Normally used at room ambient temperatures, they can operate within their specifications over a range of –10 to +60 °C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Celsius. Both power supply modules are internally connected to ground via their individual, rear-connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate connectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. • For each of the power supply modules, fit one end of the grounding lead’s push-on connector onto the grounding tab. • For the Radio Assembly chassis, install the grounding lead’s lug over the binding post and firmly hand-tighten the binding-nut. • For each power supply modules 1. Fit the slotted connector (on the other end of each of the grounding connector) under a conveniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 2. Apply anti-corrosion compound where paint scraping was done. 3. Ensure by testing continuity that a secure electrical and mechanical connection is achieved. If a –DC rail (0V) is installed as part of the system, the grounding leads may alternatively be fit-ted to the rail terminal. Caution: Improper grounding between power supply case and rack frame may result in harmful voltage potentials and/or miscellaneous power sup-ply switching noise problems in both receivers and transmitter.

120 20191-002 Paragon-III Technical Manual 9 2.5.1.1.1 T808/807 DC Power Supply Connection & Torque Settings Warning: Securing the DC Power Supply cable into the DC connector to provide a good electrical connection is essential. Over time, the wires tend to compress in the DC connector result-ing in an increasingly poorer connection. Consequently, as high current is drawn, the connector heats up increasing the resistance thereby causing still more heat until the connector eventually burns up. Although screws securing DC cables to the Power Supply terminals are tightened to the torque set-tings given below prior to new system delivery, they must be re-tightened as part of the commission-ing process and re-tightening is also part of the regular maintenance schedule. Prior to replacing a Power Supply module into an existing system, inspect the cable and re-terminate the DC wires if the strands have previously been twisted together or show any sign of damage. Cut the wire at the end of the insulation and then strip approximately .4 inch (10mm) of insula-tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screw terminal and tighten the screw to secure the cable as per the torque settings given below. Torque Settings: The manufacturer recommends torque setting all power supply terminal screws to: • 0.5 to 0.6 Nm (or 4.5 to 5.3 In/lb or to .37 to .44 ft/lb) Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver model CAL36/4K. After tightening, pull on the cable to check the cable is secured tightly into the screw terminal. 2.5.1.1.2 Power Indications • Press both red power buttons located on the front of the module to have complete power distribu-tion to the Radio assembly. The power supply front panel LEDs indications are: Table 2 - Power Supply, LEDs indications LED Color Indication On Green Power enabled * Stby Red Power disabled * OL Steady Red Current Overload On & OL Flashing green and red respectively Over voltage * To remove voltage from the power supply PCB, disconnect the main power cords. • For other Paragon-III LEDs descriptions, see section Error!

Radio Programming and Adjustments All receiver procedures detailed in this section should be done twice: once for the “Main” (or RX1) receiver module and a second time for the “Auxiliary” (or RX2) receiver module. Connect to the relevant module and its corresponding backplane PCB as required.5.1 Series II Radio Programming This procedure describes the steps needed to program the Paragon-III radio base station 700 MHz. 5.1.1 Recommended Items - 486 PC or better, MS-Windows 98 © or later - T800win programming kit for Series II: - PGM800Win programming software user's manual - PGM800Win Windows based programming software version 3.0 or later - T800-01-0002 programming cable (DB-25 to RJ-45 cable) - Standard 25-pin parallel cable (terminated Male/Female) 5.1.2 Module Programming Before starting programming, have a PC running MS-Windows © and the Tait PGM800Win software for Series II Base station. This program supports the use of a mouse but may be used without one if required. Keyboard access follows the conventional MS-Windows © method as briefly described below: - Press and hold the “Alt” key while pressing at the same time the relevant hotkey as indicated by an underlined letter on the menu command. - On a drop-down menu, press only the hotkey without pressing the “Alt” key. - Use the “Tab” key to cycle available fields and the “Enter” key to validate entries. E.g. Pressing “Alt”+F opens the File drop-down menu and pressing “A” opens the Save As directory service box. • Receiver VCO and front-end alignment will be required when new receiver frequency is pro-grammed outside the radio tuning range: 792-794 MHz = ± 3.0 MHz from previous center frequency 797-803 MHz = ± 3.0 MHz from previous center frequency • Exciter will be required when new transmitter frequency is programmed outside the radio tuning range: ± 4 MHz from previous center frequency. 1. Connect the PC, via the supplied programming lead, to the speaker panel’s front-mounted RJ11 connector. 2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Software User’s Manual to select the proper module to be programmed. 3. Program required channel's frequencies. – Do not program any CTCSS tones on channels. – Do not change any other parameters. – Refer to Figure 14, Figure 15, Figure 16 and Figure 17 for screen program examples. 4.

120 20191-001 Paragon-III Technical Manual 245.1.3 Channel Selection via DIP Switches The backplane-mounted DIP switch settings override the default channel programmed by PGM800Win. To set a default channel via the software, all DIP switches must be set to “OFF” (i.e. 00000000). When a switch is “Off”, its binary count is active; when a switch is “ON” its binary count is inactive. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to “OFF” to make the binary count total the channel number you want. Set all other switches to “ON”. Example: To select channel 1, set the DIP switches as shown below: Figure 18 - Backplane DIP switches example - Channel 1 selected Binary Value 1 2 4 8 16 32 64 Always ON except when default channel is required CHANNEL SWITCH TX - RX 1 2 3 4 5 6 7 8 O F F

Warning, The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 5.2.2.1 Initial Setup This initial setup will be used during all receiver alignment procedures described below: 1. Remove the receiver (T885) module from the Paragon-III rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the Paragon-III Extender Rail Kit for Series II to the empty chassis receiver slot. 4. Prepare the Multimeter to DC Volts. 5. Apply power to the Paragon-III. 5.2.2.2 Synthesizer Alignment Single channel: Connect the Multimeter to either side of L504 (T885) in the VCO (this measures the synthesizer loop voltage). - T885 (800/900 MHz) Tune VCO trimmer CV500 for a synthesizer loop voltage of 10VDC.

120 20191-001 Paragon-III Technical Manual 26Multiple channels (adjusting as shown for single channel above): 1. T885 Adjust the VCO loop to 10V using the middle frequency channel. 2. All channels should lie within the upper and lower limits of respectively All channels should lie within the upper and lower limits of 16V and 3V for the T885. 5.2.2.3 Front-End Alignment 1. IFR COM120B settings: a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel frequency c) Select and turn-on GEN2 d) Set the FM Deviation to ±3kHz (full channel) or ±1.5kHz (half channel) using 1KHz sine e) Select SINAD meter f) Use a X1 scope probe connected to SINAD input and monitor the Discriminator O/P on the back-plane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885). 2. Adjust the helical resonators for best SINAD: #H400, #H401 and #H900 (T885). 3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again. The absolute minimum requirement level to reach is -108dBm (typical level is -109 to -110 dBm) 4. Perform the SINAD linearity tests described in paragraph 5.2.2.4. If it fails to pass the requirement, contact your Dataradio technical support. WARNING: Do NOT attempt to re-tune the IF stages (I.e. L300 and L301 for T885) These adjustments do not need to be re-adjusted after frequency re-programming. Touching these coils will have a direct impact on the modem DSP ISI coefficient settings and may reduce signifi-cantly the radio performances over data. 5.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR COM-120: a) Generator mode, Output T/R, TX frequency to match the main radio RX frequency b) Filter set to wide band (no audio filter) c) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off. d) Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios. e) Use a X1 scope probe connected to the IFR SINAD input and monitor the Discriminator O/P on the radio backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885). 2. Lower the RF level to get a 12dB SINAD reading. Level should be better than -108dBm (including ca-ble loss). 3. Offset the IFR TX frequency 2kHz above the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on frequency SINAD reading. 4. Offset the IFR TX frequency 2KHz below the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on-frequency SINAD reading. Note: If one of the above requirements is not met, try to re-tune the front-end. If still failed, contact your Dataradio technical support.

120 20191-001 Paragon-III Technical Manual 27 5.2.2.5 RSSI Adjustment - Caution: mis-adjusting RSSI may reduce the Paragon-III's Parallel Decode (PD) performance. - BDLC-III must be connected to the radio chassis assembly during this process. 1. T885-xx-0200 (700MHz) receivers: - Refer to Figure 20 - T885-0200 Receiver Tuning Controls location - Apply an on-channel signal from the RF generator at a level of -110 dBm modulated by a 1 kHz tone at a deviation of ±6kHz. - Adjust RV 345 (RSSI level) for T885 to give 2.0V RSSI output at SK330 pin 2 or on backplane J1 (RX1) or J5 (RX2) pin 5 when measured with a voltmeter (See Figure 13 - 280 03425-001 Radio back-plane for test point location). The following RSSI graphics are given as general information only. Refer to factory technical support only if RX data performance degradation is noticed combined with something that does not look like those RSSI curves.

Connect the Paragon-III Extender Rail Kit to the empty chassis exciter slot. 7. Apply power to the base station. 5.2.3.2 Synthesizer Alignment Single channel: Connect the Multimeter to either side of L309 (T881). - T881 (700 MHz) Tune VCO trimmer CV300 for a synthesizer loop voltage of 10V DC. Multiple channels (adjusting as shown for single channel above): - T881 (700 MHz) Adjust the VCO loop to 10V using the middle frequency channel. All channels should lie within the upper and lower limits of 16V and 3V respectively for the T881. Note: Normally, the fast TX key option is installed and the synthesizer is always ener-gized. In the case where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 5.2.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR: - Receiver mode - IFR RX frequency to match the main radio TX frequency - IF Filter set to 30KHz - Zoom the RF Error window: select 10Khz range 2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier output frequency. It should be within ±300 Hz. If it is not, adjust the TCXO (IC700) to trim to meet the requirement, preferably within 100Hz.

120 20191-001 Paragon-III Technical Manual 295.2.3.4 Low-Frequency Balance Adjustment Note: • PGM800Win version 3.00 or later must be used. Electronic potentiometer (256 step) is used to allow channel adjustment of two-point modulation (Low freq. balance). 1. Apply the following settings to the IFR: – Receiver mode and Oscilloscope display (Source Demod out connector, DC coupled). – IFR RX frequency to match the radio transmit frequency – IF Filter set to 30KHz – Zoom the Deviation window: select 10kHz Range and DC coupling. 2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via dip switch, refer to Figure 17) 3. Transmit a square wave by using CDip (using a second serial port). 4. Press EPOTs button. Adjust IC220 via PGM800Win “reference modulation” to obtain the best square wave, no damping, no overshoot. (You can use either the mouse or up and down arrow keys). Record the deviation read. 5. For single-channel unit, proceed to step 8. 6. For multi-channel unit, select the highest frequency channel. Transmit a square wave via CDip. Record deviation again. 7. The difference in deviation between the two channels should be less than ±300Hz. If not, re-adjust IC220 to "average" the square wave shape on both channels until the spec is met. 8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare the devia-tion produced between 1000 Hz sine wave test tone and Random data test pattern The difference between the test tone and the test pattern should be less than 1.9 kHz for xRC16FSK modulation set For multi-channel unit, repeat this step on the highest frequency channel. 9. Select the active channel. Transmit a TX ON (Modulated) adjustment tone via CDip. Make sure that deviation level read on the IFR correspond to bit rate in use (see Table 4 at step 6). Re-adjust deviation as necessary. 5.2.3.5 Exciter Power Output 1. Apply the following settings to the IFR: - Receiver mode, Output T/R - IFR RX frequency to match the main radio TX frequency - IF Filter set to 30KHz - Select auto range in the Power reading window - Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power at the coaxial cable end connecting to the power amplifier should be: - T881 = 5W +0/-300mW (RV502, Figure 21)
