Page 4 RF Technology R501 OPERATING INSTRUCTIONS1 Operating Instructions1.1 Front Panel Controls1.1.1 MON. VolumeThe Mon. Volume control is used to adjust the volume of the internal loudspeaker andany external speaker connected to the test socket. It does not effect the level of the 600Ohm line or direct audio output.1.1.2 MON.SQThe MON. SQ. switch allows the normal squelch functions controlling the monitoroutput to be disabled. When the switch is in the MON. SQ. position the audio at themonitor speaker is controlled by the noise detector. The CTCSS, carrier and externalsquelch functions are disabled. This can be useful when you are trying to trace thesource of on channel interference or when setting the noise squelch threshold. Theaudio from the 600 Ohm line and direct outputs is not effected by the switch position.1.1.3 N.SQThe N.SQ trimpot is used to set the noise squelch sensitivity. Use the followingprocedure to set the noise squelch to maximum sensitivity.(a) Set the toggle switch to the MON.SQ. position and set the MON VOLUME controlto 9 o'clock.(b) Turn the N.SQ. adjustment counter clockwise until the squelch opens and noise isheard from the speaker. Adjust the VOLUME to a comfortable listening level.WARNINGChanges or modifications not expressly approved byRF Technology could void your authority to operatethis equipment. Specifications may vary from thosegiven in this document in accordance withrequirements of local authorities. RF Technologyequipment is subject to continual improvement andRF Technology reserves the right to changeperformance and specification without further notice.
RF Technology R50 Page 51 OPERATING INSTRUCTIONS 1.1.4 C. SQ(c) In the absence of any on channel signal, Turn the N.SQ. screw clockwise until theuntil the noise in the speaker is muted. Then turn the screw two additional turns in theclockwise direction.1.1.4 C.SQThe C.SQ trimpot is used to set the carrier squelch sensitivity. Carrier squelch is usefulat higher signal levels than noise squelch and can be used from 1 - 200 uV input.It is provided mainly for use in fixed link applications where a high minimum signal tonoise ratio is required or where very fast squelch operation is required for datatransmission. The carrier squelch will open and close in less than 2 mSec.In most base station applications carrier squelch is disabled by turning the adjustmentcounter clockwise until the screw clicks.The carrier squelch may be set to a predetermined level with the TecHelp software orby using the following procedure:(a) First turn the adjustment fully counter-clockwise. Then set the noise squelch asabove.(b) Connect a source of an on channel signal with the desired threshold level to thereceiver's RF input.(c) Turn the screw clockwise until the SQ LED goes OFF. Then turn the screw backuntil the LED just comes ON.1.1.5 LINEThe LINE trimpot is used to set the line and direct audio output level. It is normally setto give 0 dBm ( 775 mV ) to line with a standard input signal equal to 60% ofmaximum deviation at 1 KHz. The level can be measured between test socket pins 6 &1 and set as desired.1.2 Front Panel Indicators1.2.1 PWR LEDThe PWR LED shows that the dc supply is connected to the receiver and that themicroprocessor is not being held in a RESET state.

Some options are selected on a perchannel basis, and some are defined globally (i.e. the parameter is fixed irrespective ofwhich channel is selected). Below is a description of these global parameters2.1 Serial I/O ParametersThere are two serial ports. There is the main serial port which is brought out to thefront panel connector. This is referred to as PORT0. There is another serial portwhich is for factory use only. It is referred to as PORT1.The baud rate, parity, and whether hardware flow control is enabled can be defined forPORT0. PORT0 is set by default to 57.6Kbps, with No parity, and No Hardware FlowControl.
RF Technology R50 Page 72 RECEIVER OPTIONS 2.2 Receiver Low Battery Level2.2 Receiver Low Battery LevelThis is factory set to 24.0V, and defines the level of the DC supply that will cause anReceiver dc supply low alarm.2.3 Audio High Pass (Notch) FilterAt the audio output ports, the sub tone (CTCSS) can be notched by a high pass filter,this high pass filter can be software selected as enable or disable (the filter wasbypassed). The default factory setting is audio high pass filter enable.2.4 Audio ResponseThe output audio frequency response can be selected as 750uSec. De-emphasis or flatresponse, the default factory setting is 750uSec. De-emphasis.2.5 LOOP Volts SelectThe receiver can key up the transmitter with a DC current between Line+ and Line- ofthe audio output terminals. If this option is selected enable, it will be active by thesquelch switch, then a 12Vdc supply is applied to the pair through 660 ohms of sourceimpedance. If this option is disable, the loop is not used. The default factory setting isLOOP VOLTS enable.2.6 COS Polarity SelectThe COS (Carrier Operated Switch) can be selected as on with Signal or on with noSignal. The default factory setting is COS on with Signal.2.7 COS Source/Sink SelectThe COS can be used as a DC source or a free switch, if the Source option is selected,a 12Vdc voltage will be applied between COS+ and COS- terminals when the COS isoff. The default factory setting is COS Source.2.8 Channel Selectable ParametersEach channel defines two complete set of parameters. One set of parameters is usedwhen a transmitter keys up from the PTT-in input, and the other set is used when thetransmitter keys up from the LOOP-in, the PTT switch, or the microphone PTT input.Each set defines what frequency to use, what CTCSS sub-tone (if any) to use, what
Page 8 RF Technology R503.1 25 Pin Connector 3 RECEIVER I/O CONNECTIONSmaximum line deviation to use, what tone deviation to use, what transmit delay (adelay applied from PTT-in or LOOP-in to transmission), what transmit tail (delayfrom PTT-in, or LOOP-in, to transmission being stopped, and No-TONE period (aperiod of extra transmission in which No Tone is applied after PTT-in or LOOP-in hasbeen released.As well as these parameters, which Line (or Lines) can be selected, and whether theLines should have Flat frequency response or have Pre-emphasis applied. Also, it canEnable or disable the extra 20dB gain pad.Note that both Line1 and Line 2 can be selected (each with or without pre-emphasis),and if so, then the two signals will be mixed, and the Line potentiometer will adjustthe level of them both.3 Receiver I/O Connections3.1 25 Pin ConnectorThe female D-shell, 25 pin, connector is the main interface to the transmitter.

This software can be run on an IBM compatible PCand can be used to calibrate a T50, R50, and PA50 as well as program channelinformation. See the Eclipse 50 users manual for further information.But the R50 also has its own stand-alone high level interface, which can be accessedfrom a VT100 compatible terminal, or terminal emulator (such as HyperTerm which isavailable as a standard accessory with Windows).The pertinent aspects of this High Level Interface are described below.4.1 Setting OptionsNote that any text in italics, represents data output by the R50 firmware, rather thancommand line data sent to the R50 firmware.The R50, after powering up, will issue a command prompt of the form:R50>Via a terminal, or a terminal emulator, a user can type various commands in. The basiccommand to read parameters is:

It can be done by typing thefollowing at a command prompt:R50> set chan chan_number parameter_listWhere chan_number is a number from 0 to 99.The format of the parameter_list is quite complex. It has 14 fields. Each field can beseparated by a colon(:), comma(,), space, or tab.For example set chan 0 25.0:35.0,100.0,120.0,0,5,2,0,5,2,10,11,0,3Field1: Receive Frequency(in MHz).

This is 35.0 MHz in the example.Field3: CTCSS Tone(in Hz) if PTT-in is asserted. This is 100Hz in the example.Field4: CTCSS Tone(in Hz) if the exciter is keyed up by anything but PTT-inbeing asserted. This is 120Hz in the example.Fields 5,6,7: These define the start-up delay (in hundredths of a second), the transmittail (in seconds), and the no tone period (in tenths of a second) if the exciter keys upfrom PTT-in being asserted.Fields 8,9,10: These define the start-up delay (in hundredths of a second), the transmittail (in seconds), and the no tone period (in tenths of a second), if the exciter keys upfrom anything other than PTT-in being asserted.Field 11: Selects the line parameter if PTT-in being asserted caused the exciter to keyup. In the example it has disabled the 20dB gain pad, and enabled pre-emphasis onLine 2 (Line 1 is disabled).Field 12: Selects the line parameter if anything other than PTT-in being assertedcaused the exciter to key up. In the example it has disabled the 20dB gain pad, and itwould enable pre-emphasis on Line 1 and Line2 (i.e. audio on each input is mixed).Field 13: Selects the Tone deviation and the Maximum Line deviation if the exciterkeys up from PTT-in being asserted In the example, it has selected the defaultmaximum line deviation (5kHz), and the default tone deviation of 750Hz.

It is controlled by the noise squelch detect, carrier squelch, or externalsquelch signalSQ is a CPU output that when low turns 600W line and direct audio path on. It iscontrolled by the noise squelch detect, carrier squelch, or external squelch signalN_BLK_EN is a CPU output that when low turns noise blanker option off.CTCSS_SEL is a serial bus select pin. It is used to select the FX805 chip(U500),which is used to decode CTCSS tones. (see 5.5)PLL_SEL is a serial bus select pin. It is used to select the PLL chip in the PLL circuit(U302). (See 5.6)RCV_ADSEL is a serial bus select pin. It selects the quad Digital to Analogueconverter (DAC) that sets the levels for the 12MHz reference oscillator bias voltage,21.855MHz oscillator bias voltage, noise squelch comparator bias voltage and theLCD bias circuit.

Page 14 RF Technology R505.3 RF Section (Sheet 3) 5 CIRCUIT DESCRIPTIONDBGTX_TTL, DBGRX_TTL are RS232 transmit and receive (TTL) data pins whichare connected to the debug port after conversion to/from RS232 compatible voltagelevels by U202 and U201.TXD_TTL, RXD_TTL, RTS_TTL, CTS_TTL, DTR_TTL, DSR_TTL, are RS232data pins which are connected to the main front panel serial port after conversionto/from RS232 compatible voltage levels by U202 and U201.N_DET is used to sense the noise squelch output of the receiver section. (seeSUBTONE_IRQ is used to sense the subtone decoded comes from the FX805 (U500).INT is the CPU interrupt input pin which is used to detect the external squelch signal.BKGD is a bi-directional I/O pin used to communicate with the core of the CPU. It isconnected to the debug port and is utilised by specialised hardware to control the CPUexternally, even without any firmware being present in the Flash.The RESET pin is both a low active input and a low active output to the CPU. Ifgenerated externally to the CPU, it forces the CPU into reset, and if the CPU executesa RESET instruction this pin will be driven low by the CPU.Whenever there is insufficient volts (< 4.65V) on pin 2 of the MC33064D (U203), itwill keep its RES output low. After the voltage has met the right level it will assert itsoutput low for another 200 milliseconds. Thus the CPU will be held in reset untilVCC is at the correct level. Thus the PWR_OK LED will only light when VCC iswithin specification, and RESET has been released.S200 is a momentary push-button switch that, when pressed, will cause the CPU to bereset.MON_SQ is a CPU output to set the monitor speaker on or offLCD_RS, LCD_R/W, and LCD_E are reserved for interfacing to an LCD displaymodule. Note that this feature has not been implemented.U205 is used to select whether the Flash or RAM is to be read or written.U207 is a single supply, 5V, TSOP40 Flash chip of size 8, 16, or 32 Megabits, and isused to store the firmware.U208 is a 1, or 4, Megabit Static RAM in an SOP-32 package, and is used for bothcode and data.

U303A, U303D are buffers thatsend the bias voltage of two VCOs to MicroController U204.U304A, U304B convert the F0LD of the PLL chip to a square wave by a division of100, and send the signal to MicroController U204.5.4 Receiver Section (Sheet 4)RF input signal (25MHz-50MHz) is filtered by a high pass filter (C401, C402, C403,C407, C415, C416, C417, C419, C420 and L401, L404, L405, L406) and a low passfilter (C404, C405, C406, C421, C422 and L402, L403, L407, L408). Q401 is thefront-end amplifier, capacitors and coils between Q401 and C440 provide additionalfiltering for RF signal amplified by Q401. MX401 is a double balanced mixer whichconverts the RF signal to the 1st IF, the frequency of the 1st IF is at least three timeshigher than the highest RF frequency to obtain a good image and spurious rejection. InR50 receiver, the 1st IF frequency is 246MHz.Q402 is used to amplify the 1st IF signal, FIL401 is a SAW filter which provides anexcellent spurious rejection for the 1st IF. The filtered IF signal is then fed to a doublebalanced mixer MX402, the output of MX402 (the 2nd IF) is amplified by Q403, the2nd IF frequency is selected at 21.4MHz to avoid the interference from in band RFsignal.Q404 is a gate of the noise blanker, the gate is controlled by the impulse noisedetector.FIL404 and FIL405 are two 21.5MHz crystal filters which can be equivalent as a fourpole crystal filter, the filer provides minimum 40dB attenuation at adjacent channelfrequency. C448, C477, L423 and components between FIL405 and U401 arematching network for the filter.U401 is IF receiver IC which includes mixer, oscillator, amplifiers and discriminator.The frequency of oscillator is 21.855MHz, it can be tuned by the 3rd_LO_ADJvoltage.The product of mixer is 455KHz, build in amplifiers of U401, FIL402 and FIL403provide sufficient gain and adjacent channel rejection for 455KHz IF signal to bediscriminated.Pin9 of U401 is recovered audio output, C411, C412, C413 and R441, R444 andU402A are working as a high pass filter to eliminate the audio frequency, U402Bamplifies the FM noise signal, D403 and C438 convert the noise level to a DC voltage.U402C works as a comparator, the offset voltage can be set by the OUTC of U301.
Page 16 RF Technology R505.5 Voltage Controlled Oscillator (Sheet 5) 5 CIRCUIT DESCRIPTIONPin8 of U401 is the other recovered audio output which can be muted by pin5,discriminated audio signal is amplified by U605A to a sufficient level for line leveldetector, then fed into Audio Section (Sheet 6).Pin7 of U401 is the Radio Signal Strength Indicator (RSSI) output, U402D is a bufferfor send RSSI voltage to MicroController.Q405 and Q406 are amplifiers for impulse noise signal, the impulse noise is thendetected by D401 and U403, C489, R450 and U404 form a 2uSec noise blanking pulsewhen the impulse noise is detected. Q408 converts the CMOS level to a requiredswitch level to control the noise blanker gate Q404.U303B and Q407 work as gain control circuit to reduce the Intermodulation which isproduced from impulse noise amplifiers.5.5 Voltage Controlled Oscillator (Sheet 5)There are two similar VCO circuits in this sheet, the difference between these twoVCO is component values, so only one VCO circuit is illustrated in this section.Q501, C532, C533, C534 and L501 are working as a Colpitts oscillator, the frequencyof the oscillator is decided by the tuning voltage of a varactor D501 which comes fromthe loop filter of the 1st PLL. Q503 is used to reduce the noise on power supply. D503,R517 and C519 are working as AGC circuit to improve output of the VCO signal.MMIC amplifier MA501 provides about 20dB gain for the VCO signal and feeds it tothe PLL chip. MA502 and MA503 provide about 30dB gain of the VCO signal todrive the double balanced mixer MX401, Q506 and those components of which valuewith "*" are not used in this version, they will be used in case of higher drive powerwhich is required by some high LO level mixer.5.6 Audio Processing Section (Sheet 6)U605B, R642, R643, R644, C626, C627 and C628 are working as a 3KHz low passfilter, in addition, the discriminated audio signal level from U605A is attenuated bythe low pass filter to fit the dynamic range limitation of CTCSS chip U602.U602 is a CTCSS tone encoder and decoder. The integrated circuit is also capable ofgenerating and receiving DCS signals, but at this stage this has not been implemented.The CPU accesses U602 via the serial bus using MOSI, SCLK, and the low activeSelect signal CTCSS_SEL.4MHz crystal X401 is used as the reference of the CTCSS decoding. The build-in highpass filter of the audio path (Pin 10 to Pin 11) can eliminate the subtone, this filter canbe bypassed by the MicroController. The subtone output from Pin17 is amplified byU605C, through C604 connected to the DB25 terminal on rear panel.
RF Technology R50 Page 175 CIRCUIT DESCRIPTION 5.7 Power Generator Section (Sheet 7)U609B, U607A and U607B are working as a flat/de-emphasis response switch, it canbe selected by control signal FLAT and DE_EMPHA from the MicroController U204.U607D and U607C is the squelch switch for line output and speaker.U609C is the amplifies for 600W line output, U609D is the amplifier for direct audiooutput, the output level of 600W line an direct audio are adjustable via VR601 on thefront panel.U604 is the power amplifier for internal and external speaker, the power level can beadjusted by VR602 on the front panel.Depending on the squelch, RL602 will apply a 12VDC to the 600W line output whenloop function is selected. If the loop function is not used, RL602 always stay in theposition of which C619 is bypassed. The position of RL602 is controlled by the signalLOOP/VOLTS_SEL from the MicroController U204. Opto-coupled transistor Switch U601 provides a COS (Carrier Operated Switch)output which is controlled by COS_POLARITY signal from the MicroController. Theoutput COS+ and COS- can be used as +12V DC source or a free switch depending onthe status of the relay RL601, RL601 is controlled by COS_VOLTS_ON/OFF signalfrom the MicroController U204.Discriminated audio level is detected by D604 and C623, signal LINE_LEVEL isconnected to the analog-digital converter input pin of the MicroController forcalibration purpose.5.7 Power Generation Section (Sheet 7)There are three switch-mode dc-dc converters in the board. These use monolithicconverters based on the National LM2595. Two of the converters are 12V convertersand one is a 5V converter.The power in to the whole exciter is the voltage rail 28V.U907 converts this down to 12V.U908 is set up as an inverter, and uses the 12V rail to create -12V.U909 converts the +12V rail to +5V for all the digital circuitry.The +12V rail is used to power the two on-board relays, as well as up to one extra off-board relay. It is also dropped, via a linear regulator (U910) to produce the +10V rail,which in turn is dropped by another linear regulator U911 to produce +5Q.Similarly U913 and U914 are linear regulators that produce -10V and -5V from the -12V output of U908.+2.5Vand -2.5V are not used in the R50 receiver, the reason of being showed on theschematic diagram is to keep same design of the T50 power generation section.
Page 18 RF Technology R506 FIELD ALIGNMENT (CALIBRATION) PROCEDURED911 is a 4.096V (3%) reference diode. Its output is buffered by U906 which thenproduces a reference voltage rail Vref, which is used by the CPU's A/D converter, andthe DACs.6 Field Alignment (Calibration) Procedure6.1 Standard Test EquipmentSome, or all of the following equipment will be required:Power supply set to 28Vdc, with current >1A.RF Signal Generator50 Ohm Output impedanceFrequency range 25-50MHzFM modulation at 1KHz3KHz peak deviation for 25KHz or 20KHz channel spacingFrequency CounterThe accuracy should be at least 0.5ppm, preferably 0.1ppmTrue RMS AC voltmeter, and a DC voltmeter.6.2 Invoking the Calibration ProcedureThe R50 has in-built firmware to perform calibration. This firmware requests the userfor information as to meter readings, and/or to attach or adjust the AF signal generator.The firmware based calibration program can be accessed from a terminal, a terminalemulator, or the Eclipse50 terminal emulator.As for Section 4.1, the firmware, after power up, issues the following prompt:R50>Via a terminal, or a terminal emulator, a user can type various commands in. The basiccommand to start the calibration procedure is:R50> cal calibration_typeWhere "calibration_type" is one of:(a) misc: Miscellaneous parameters are defined and calibrated(b) line: Line1, Line2, Dir Aud (Tone), and microphone inputs are tested andcalibrated.(c) ref: The reference oscillators are adjusted and calibrated(d) all : (which does all the above)
RF Technology R50 Page 196 FIELD ALIGNMENT (CALIBRATION) PROCEDURE6.3 The "Miscellaneous" Calibration ProcedureR50> cal miscThis procedure should not normally be invoked as part of any field maintenance.The program will print out the Model Name and Serial Number of the exciter. If theseparameters haven't already been defined (e.g. at an initial calibration, at the factory,the service personnel will be prompted to enter these values).Then it will ask the operator to enter the value of Vref (as measured at TP913, see5.7).Measure the voltage, at TP913 (Vref)and type it on the command line...Unless the reference diode D911 has been replaced, this should not be done. The usershould simply hit the Enter key to bypass this operation. If, though, D911 has beenreplaced for some reason, then, the lid of the unit should be removed, and the voltagemeasured. TP913 can be found just above JP12 (near the centre of the exciter).Then the receiver low battery alarm level will be asked for. If the current value isacceptable, the User need only hit the Enter key on the keyboard. If another value ispreferred, then that value can be typed in.For example:The Exciter's Low Battery Alarm is 24VIf this is correct enter <RET>,else enter the new value: 26In this example, the low Battery Alarm level is changed to 26V.Then the user will be prompted for serial port baud rates, parities etc. Please leavethese parameters unchanged unless you are familiar with how to change suchparameters on your PC. The Eclipse50 software will expect 57600 BPS, and NoParity, and No Flow Control. Note well, that if you do change any of these, thechange will not take effect until you power down the receiver and then power it upagain. (As an alternative to power cycling the receiver, and if the cover is off thereceiver, you may simply press switch momentary push-button S200 (see 5.2).Then the following questions are:Is Flat frequency response on by default (Y/N)?Is COS purely a sink of current (Y/N)?Is COS Asserted when the Squelch is closed (Y/N)?Is COS UnAsserted when the Squelch is open (Y/N)?Is LOOP Asserted when the Squelch is closed (Y/N)?Is LOOP UnAsserted when the Squelch is open (Y/N)?Always hit "Enter key" unless the value other than default is required, note use the "Y"key if default value need to be changed.

Also this procedure is used to set the 600 Ohm audio line outputlevel, Noise squelch level and Carrier squelch level. Simply follow the instruction ofthe software as bellow:Attach an RF signal generator to the input.Set the RF output to 37.5MHz,and an input level of -110dBmwith a 1kHz tone and 3kHz deviation.Adjust the Volume Pot until the DIR AUD outputis 388mV.(eqvt to 0dBm into 600 ohms)Enter <RET> when done.Set the RF signal generator's output to -60dBmEnter <RET> when done.rssi_scale is 0.417dBm/dac step, and rssi offset is -137.500dBm) --- for exampleAdjust the Modulation to only 1KHz max deviationEnter <RET> when done.deviation_scale is 1.000dBm/dac step, anddeviation offset is .000dBm --- for exampleAdjust the Carrier Squelch to the desired levelEnter <RET> when set.-99.5 --- for exampleEnter the Fast Noise Threshold(in dBm):Enter the Carrier Alarm Threshold(in dBm):Set the RF generator output to the desired level ( < -105dBm ),and adjust the N.SQ adjustment counter clockwiseuntil the squelch opens, thence turn it clockwiseuntil the noise is muted.Enter <RET> when done6.5 The "Reference" Calibration ProcedureR50> cal refTo compensate for crystal ageing and other parameters that drift, the followingprocedure should be performed approximately once per year.Open the cover of the receiver, find out the test point TP209 on receiver PCB, using afrequency counter to measure the frequency and follow the instruction as bellow:
