Functional DescriptionGenerally, vehicular repeaters are used as mobile extenders in cross-band operation: the link is VHF/UHF/800

MHz simplex and the mobile is Lo-band, VHF, UHF or trunking. In-band operation is possible, but care must betaken to prevent interference between the mobile's higher power transmitter and the repeater receiver. Properfrequency selection and antenna placement are important even in cross-band operation, but especially for inbanduse. The use of low power pre-selector cavities may be placed in line with the repeater antenna cable since it issimplex and low power.

Important NoteThe SVR-200 operates on simplex frequencies; part of the multi-vehicle format dictates that all of the

SVR-200s must be able to monitor all link traffic on site and be able to determine if a handheld is transmitting, orif other repeaters are transmitting. The handhelds must transmit CTCSS, but should be carrier squelch receive.The handhelds should not use CTCSS decode if the repeater is utilizing the multi-vehicle format, as this willinterfere with the priority sampling which is essential for multi-vehicle operation. Also, the handhelds would haveto have different encode and decode tones in order for the repeater to be able to tell the difference betweenhandhelds and other repeaters, so the handhelds would not be able to hear each other. The repeaters should nottransmit CTCSS unless used only in a single vehicle environment.

When the user leaves the vehicle, they activate the SVR-200 via their mobile radio front panel or a separateswitch. When the mobile radio is receiving carrier and proper tone, the SVR-200 will begin transmitting on thehandheld’s receive frequency. The user is able to hear and respond to all radio traffic, including other handheldsat the site. The SVR-200 can be programmed to give the handhelds priority in a conversation by periodicallysampling for handheld activity (carrier and proper tone) during base-to-portable transmissions. During sampling,if the SVR-200 detects a handheld transmission, it will cease transmissions, key the mobile radio and repeatportable-to-base. This allows the handheld to respond during repeater hang time or during full duplex interconnectcalls. Priority sampling can be enabled/disabled through PC programming and the interval can be programmedbetween .25 seconds and 2.5 seconds in .25 second increments.

The SVR-200 has a fixed 3 minute time out timer for base-to-portable transmissions. If the mobile COR isactive for more than 3 minutes (and the SVR-200 is the priority unit) it will send a double blip and cease transmissionuntil the mobile COR is inactive. The 3 minute time-out is in affect regardless of whether the SVR-200 isprogrammed for priority sampling or not.

Multi-vehicle operationWhen the SVR-200 is first activated, it will transmit a short “lock tone” that alerts the user that the system isfunctioning. It will then assume the priority status and be ready to repeat any base-to-portable or portable-to-basetransmissions. If another unit arrives on scene and is activated, it too will transmit the “lock tone”; when the firstSVR-200 detects the lock tone from the second unit, it will increment a “priority counter” and will no longer repeatany transmissions. The recently arrived unit will be the priority repeater, and the first unit will be 1 count away frompriority. This process will continue for each unit that arrives at the site, creating a priority hierarchy for up to 256vehicles, each with a unique count and only one unit at priority status. The SVR-200 will not transmit it’s lock toneif the radio channel is busy when first enabled. It will wait in non-priority status until all transmissions cease, thensend its lock tone and become the priority unit.

Even though the other SVR-200s are not at priority status, they will continue to monitor the channel for activity.If the priority unit were to leave the scene or become disabled, the other units will detect the condition to repeatand determine that there is no priority unit repeating the transmission. They will then begin to decrement theirpriority counters until one of them reaches the priority status and begins repeating the transmission. Since theSVR-200s are all at different counts, only one will reach priority status and begin transmitting. The other units willsense the new priority repeater and cease counting down, preserving the priority hierarchy.


If another unit were to arrive from a different scene and it is still the active priority, there will be two activerepeaters on the air when a condition to repeat exists. When one of the SVR-200s unkeys to check for handheldactivity, it will detect the presence of the other active SVR-200 and increment it’s priority counter and ceasetransmission. This is the self clearing mode to prevent radio collisions.

If the handheld operator is out of the vehicle and their partner still in the vehicle were to key the mobile radiousing the local mic, the SVR-200 will detect the local PTT and repeat the transmission to the other handhelds sothat both sides of the conversation will be heard by everyone on the link. The local mic repeat function can beenabled/disabled via the PC software.

The SVR-200 also has a local receive audio speaker jack that enables the person in the vehicle to monitorportable-to-base transmissions that are being repeated through the mobile.

If the users wish to communicate portable-to-portable without accessing the mobile repeater, they may transmiton the same frequency without CTCSS (or a different CTCSS); the SVR-200 only responds to carrier and propertone from the handhelds.

Trunking operation

When the SVR-200 is connected to a trunking mobile and the handheld operator wishes to access the system,they key their handheld briefly then release. The SVR-200 will attempt to acquire a voice channel on the trunkingsystem by keying the mobile for 200mS and monitoring the on-air detect line from the mobile. If it does not seethe radio transmit at all (system is busy), it will send a low tone to the hand held operator to alert them that the systemis busy. The SVR-200 will automatically retry every 5 seconds and send busy tone to the handheld with eachunsuccessful attempt to indicate progress of the call attempt. If unsuccessful after 30 seconds, the SVR-200 willtransmit intercept tone to alert the handheld operator that the call attempt failed.

When the SVR-200 detects that the mobile is transmitting, it will continue to monitor the on-air line until thetransmitter remains keyed for at least 250mS to ensure that the radio is merely handshaking or retrying. Aftersuccessful acquisition of a voice channel, it will continue to hold the mobile PTT active for 2 seconds and transmita go-ahead blip to the handheld operator. The user then keys their handheld to speak on the voice channel. If theuser does not key up within the 2 second period, the SVR-200 will unkey the mobile and send intercept tone asbefore.

If the user keys their handheld only once, or they key the first time for more than 1 second, the SVR-200 willcancel the call attempt and send intercept tone to the handheld operator. All of the queuing and error tones will onlybe sent if the handheld is not transmitting to ensure that the user hears the proper tones.

LEDs

CPU: Flashes at a 1 Hz rate to indicate proper operation of the microprocessor.PRI: When on, indicates that the unit is at priority count zero and will repeat all transmissions.RCOR: Repeater Carrier detect.RTONE: Repeater sub-audible decode; when on, indicates a condition to repeat portable-to-base.RTX: Repeater transmit indicator.MCOR: Mobile unmute detector indicating a condition to repeat base-to-portable.MTX: Mobile transmit indicator.OPT: Should be on steady during programming operations only. If OPT LED flashes at 10Hz rate, it is an

indication that the PLL did not lock within the allotted 50mS and the unit should be serviced.


InstallationBefore installing the SVR-200, ensure that the RF and repeater sections are properly aligned per the tuning

instructions on pages 8-14 of this manual. Additionally, ensure that the SVR-200 jumpers are properly configuredfor use with the particular mobile radio that it will be connected to:

J1 Controls the maximum drive level of the transmit audio output to the mobile radio. If J1 is installed, output ampU1B will have an adjustment range of 0-100 mVPP. If J1 is removed, U1B can be adjusted between 0-5VPP.

J2 Controls the output impedance of the transmit audio line to the mobile radio. If connected to a low impedancepoint in the mobile, installing JP2 sets the output impedance to 600 ohms. If JP2 is open, the output impedanceis 2.2Kohms. Install the jumper for radios that require a lot of modulation drive or that have low impedancemicrophone circuits. Remove the jumper if the SVR-200 installation decreases local microphone audio at themobile.

J3 Used for testing the SVR-200 receiver and setting the lock tone deviation transmit level. If JP3 is shorted atpower up, the SVR-200 receiver will be active all of the time and receiver audio will be heard at the speakerregardless of the repeater squelch setting or CTCSS tone decoded. Remove the jumper and turn the SVR-200off to return to normal operation. If JP3 is shorted while power is applied, the SVR-200 will go into transmitmode and send lock tone for as long as the jumper is shorted. Remove the jumper to return to normal operation.

J4 Used to internally tie the local mic input of the SVR-200 to the transmit audio output line which is usuallyconnected to the mic hi line in the mobile.

J5 Used to internally tie the on-air detect input of the SVR-200 to the PTT output. Do so only on conventionalradios; trunking radios must have the on-air detect line connected to a line indicating that the radio istransmitting.

J6 Changes the maximum gain of the local mic input amp from unity (Out) to 10x (In).

J7 Changes the maximum gain of the receive audio line input from unity (Out) to 7x (In).

J8 Adds a pull up (+ position) or pull down (- position) resistor to the remote enable line (blue).

J9 Adds a pull up resistor (10K to 5VDC) to mobile COR line (violet)

J11 Removing J11 adds 100K ohm resistor in series with SVR-200 mobile transmit audio path. Used for situationswhere mobile radio has noise on transmit audio.

J12 Enables external speaker circuit.

Make the connections between the mobile radio and the SVR-200 cable as follows:

Pin 1: Ground. Connect to the radio's chassis or ground plane.

Pin 2: Mobile transmit audio. Connect to the mobile transmit audio path or tone input. If connected beforepre-emphasis, ensure that the SVR-200 is programmed for de-emphasis (common data). If connectedafter pre-emphasis, ensure that the SVR-200 transmit audio path is programmed as flat. Pin 2 is ACcoupled and has an output impedance of 600 or 2.2Kohms (determined by J2). RV3 sets the transmitaudio output level and J1 sets the adjustment range between 0-5VPP (J1 open) or 0-100mVPP (J1shorted).

Pin 3: Remote enable/disable. Connect to the radio's auxiliary output or a separate switch to remotely enableor disable the repeater. If this line goes high to activate the repeater, ensure that JP1 is set to the “+”position. If this line goes to ground, set JP1 to the “-” position. J8 has two positions to add a pull up(+) or pull down (-) resistor to this line if used with an open collector or dry contact output.

Pin 4: Mobile PTT output. Connect to mic PTT on the mobile radio, or a line that goes active low to transmit.Pin 4 is an open collector output rated at 100mA at 50VDC.

Pin 5: 12 VDC input. Connect to the radios 12V switched supply or a point capable of supplying at least 1.5Aof current.

Pin 6: Mobile receive audio. Connect this line to the mobile receive audio path before the volume control.If pin 6 is connected before de-emphasis, ensure that the SVR-200 receive path is programmed as flat(common data). If connected after de-emphasis, program the receive path for pre-emphasis. Pin 6is AC coupled and high impedance (>15K ohm). RV5 sets the receive audio level sensitivity; this inputshould be between 30mVPP and 5VPP. J7 sets the gain of the receive input amp. If open, the inputhas a maximum gain of one; if installed, the input has a maximum gain of 7.

Pin 7: Mobile COR detect. This line is used to indicate when the SVR-200 should repeat the transmissionto the handheld. Connect to a logic point in the radio that indicates proper tone and carrier have beendetected or the audio unmute line. If this line goes more positive during an unmute condition, programthe mobile COR line as active high (common data). If the line goes more negative during an unmutecondition, program the mobile COR line as active low. The input from pin 7 is high impedance and doesnot have to go rail to rail. The SVR-200 uses a voltage comparator as a COR threshold detector. RV1sets the mobile COR threshold level and should be set for half way between the mute and unmute levelsat pin 7. Example: If Pin 7 is connected to a point that goes from 0VDC (mute) to 5VDC (unmute),set RV1 for 2.5VDC and program the mobile COR line as active high. If Pin 7 goes between 7.2VDC(mute) and 5.8VDC (unmute), set RV1 for 6.5VDC and program the mobile COR line as active low.

Pin 8: Local mic audio. If programmed for local mic repeat, the SVR-200 will go into transmit mode andrepeat the audio from this line whenever the mobile radio is keyed by the local mic. Connect this lineto the mobile transmitter audio path before limiting or filtering. This input is AC coupled and highimpedance (>5.6Kohms). The input level at this pin should be 300mV to 5VPP. RV2 sets the localmic sensitivity. If the mic high line has sufficient drive for this input, install J4 and leave pin 8unconnected. J6 sets the gain of the local mic input amp. If open, the maximum gain is one; if installed,the maximum gain is 10.

Pin 9: On-Air detect.Trunking: Connect to a point in the radio that indicates the mobile transmitter is actually on the air.This is not the same as mic PTT. If pin 9 goes positive during transmit, program the on-air detect linefor active high (common data). If pin 9 goes to ground during transmit, program the on air detect linefor active low.

Conventional: Used for local mic repeat indication from the mobile. Connect pin 9 to pin 4 of theSVR-200 and program the on-air detect line for active low. Solder jumper J5 will connect pin 9 to pin4 (PTT output) and can be used on conventional systems only. Do not install J5 for trunkingoperation.

Install the SVR-200 in the vehicle using the supplied mounting bracket and hardware. Install the unit whereit will be easily visible by the driver and will not interfere with the drivers vision or constitute a hazard during a vehiclecollision. The SVR-200 mounts in the bracket using the four 8-32 x ¼" machine screws. Do not use longer screwsto mount the SVR-200 to the bracket or circuit damage may result.

Radio Type: Select either conventional or trunking. If a trunking mobile is selected, the SVR-200 will go throughthe voice channel acquisition procedure during portable-to-base repeat mode.

On-air polarity: Select either active high or active low. This line is used to monitor the local mobile PTT for localmic repeat on conventional radios. On trunking radios, it is also used to determine if the mobile is actuallytransmitting.

TX Audio: If the mobile transmit audio output from the SVR-200 is connected after pre-emphasis in the mobile,select Flat response. If connected before pre-emphasis or to the mic input, select De-Emp.

RX Audio: If the receive audio coming from the mobile is connected to the discriminator or before de-emphasis,select Flat response. If connected after de-emphasis, select Pre-Emp.

Lock Tone: Select either 682.5, 832.5 or 847.5 Hz. All units in the system must have the same lock tone frequency.

Local mic repeat: Enables or disables the local mic repeat function; if enabled, ensure that the on-air polarity inputis correctly configured.

Courtesy Blip: (Firmware version 3.02 & above) Enables or disables the courtesy tone at the end of eachportable-to-base transmission. The tone verifies the handheld is within range of the repeater and transmission wassuccessful. It also serves to notify other handheld users that the channel is clear for use.

Pri-sampling: Enables or disables the pri-sampling feature of the SVR-200. If used in multi-vehicleapplications, this must be enabled for proper operation. During base-to-portable repeat mode, the SVR-200transmitter will switch to receive mode to check for other repeaters or handheld activity. If another repeater isdetected (carrier without/wrong tone) the repeater will cease activity to prevent radio “collisions”. If handheldactivity is detected (carrier & correct tone) the SVR-200 will switch to portable-to-base repeat mode.

Sampling rate: If pri-sampling is enabled, this selects the sampling interval. The range is 0.25 seconds to 2.5seconds in .25 second increments. The higher this setting, the longer the handheld operator must wait beforespeaking after pressing PTT during base-to-portable repeat mode, since the repeater may still be in transmit mode(there is no delay if the repeater is idle). If the interval is too short, some users may complain about the “chop”that is heard in the handhelds.

TransferSend: Downloads the current configuration to the repeater. The program will prompt you to make the FY-1connection before downloading. Download takes approximately 5 seconds.

Receive: Uploads the current data from the repeater. The program will prompt you to make the FY-1 connectionbefore uploading. Upload takes approximately 4 seconds.

Comm Port: Selects the serial port to use for uploading and downloading between the PC and the SVR-200. Commports 1-4 are supported.

Theory of OperationReceiver:

The receiver is a double-conversion superheterodyne type, designed for narrow band FM reception. The firstlocal oscillator is derived from the frequency synthesizer. The second LO is crystal controlled.

RF Stage: The incoming RF signal from the antenna jack is directed to the first RF bandpass filter to improveselectivity and then to the input of the RF amplifier. The output of the RF amplifier is then presented to a secondbandpass filter.First LO/Mixer: The first LO signal is developed by the synthesizer and is mixed with the incoming signal toproduce the first IF frequency (45 MHz). The IF frequency is filtered by FL1A and FL1B and amplified by theIF amplifier before being presented to the second LO/Mixer IC.Second LO/Mixer: The first I.F. signal is presented to the second IF IC (MC3371) which performs the functionsof second LO, second I.F. amp and mixer, FM discriminator and squelch. The second LO crystal (44.545 MHz)is mixed with the 45 MHz first I.F. signal to produce the second I.F. frequency of 455 kHz. A 6 pole ceramic filterprovides selectivity for the 455 kHz signal.Detector/Squelch: The MC3371 demodulates the 455 kHz signal via quadrature coil to produce the audio and noisecomponents. The output of the MC3371 is the recovered audio and the RSSI voltage (receiver signal strengthindicator) which is compared by the controller board with a threshold voltage level for squelch setting.

VHF TransmitterThe output of VCO buffer U8 is input to the predriver transistor U7. The output of U7 drives the RF driver

Q8. The collector of Q8 is fed by the transmit 9V line from Q10. The final amp Q13 is a class C power amplifierand drives the output lowpass and harmonic filter, C47-C50 and L20-L22. D3 is the transmit output switch andL19 is a ¼ wave transmission line to isolate the receiver switching diode D2. RF output power is controlled bychanging the bias on the gate of Q13 via the TX 9V line (pin 3) from the controller PCB.

UHF TransmitterThe output of VCO buffer U6 is input to the predriver transistor U5. The output of U5 drives the RF driver

transistor Q4. The collector of Q4 is fed by the transmit 9V line from Q5. The final amp Q3 is a class C poweramplifier and drives the output lowpass and harmonic filter, C39-C42 and L26-L28. D3 is the transmit output switchand L14 is a ¼ wave transmission line to isolate the receiver switching diode D2. RF output power is controlledby changing the bias on the gate of Q3 via the TX 9V line (pin 3) from the controller PCB.

700/800/900 MHz TransmitterThe output of the transmit VCO is buffered by U5 input to the driver transistor U1. The output of U1 drives

the RF hybrid output amp U4 through lowpass filter FL3. The final amp U4 is a class C power amplifier and drivesthe output lowpass and harmonic filter FL4. U7 is the Tx/Rx antenna switch. RF output power is controlled bychanging the voltage on pin 1 of U4 via the TX 9V line (pin 3) from the controller PCB.

Control BoardPower Supply: DC power comes from the mobile radio via P1 pins 1 and 5. Fuse F1 and MOV VAR1 provideover current and voltage spike protection. Q3 is the remote enable/disable pass switch, controlled by Q1 and Q2via P1 pin 3. Q3 output is switched 12VDC and is presented to audio amp U6, and voltage regulators U7 and U8.Bias voltage for the op-amp circuits is provided by voltage divider R68, R69 and buffer amp U2A.Transmit audio path: Receiver audio from the mobile is input to the mic amp portion of U4; PC programming ofthe SVR-200 provides flat response or +6db/octave pre-emphasis. The output of the mic amp is internally connectedto the limiter and lowpass filter. When a condition to repeat exists (base-to-portable) U4 audio is switched on andaudio is presented to amplifier/limiter and lowpass filter to remove audio components above 3kHz. U4 provides-48db/octave of attenuation to out of band signals. Transmit audio is output on pin 22 of U4 and passes throughthe final lowpass filter U2C to remove any clock noise generated by U4’s switched capacitive filters before beingpresented to the RF module on P2 pin 6.


Receive audio path: Receiver audio from the transceiver module is input on P2 pin 13 and presented to U5 pin10 and pin 16. Pin 10 is the input of the receiver highpass filter to remove any sub-audible signals before being outputon pin 11 and sent to U4 for receiver audio processing. Pin 16 is the input to the sub-audible tone decoder sectionof U5. Receive audio entering pin 7 of U4 is processed as flat, or -6db/octave depending upon PC programming.The receive audio then passes through the internal lowpass filters to remove unwanted noise and output on pin 21,where it is sent to the local receiver audio amp and mobile transmit audio output amp U1B. J1 selects either highsensitivity (open) or low sensitivity (shorted) and J2 selects the output impedance (600/2.2K Ohms).

Sub-Audible tone signalling: U5 processes the sub-audible signal from the receiver by comparing the incomingsignal to previous samples in a noise correlator. If the signal is sufficiently coherent, the output of the comparatoris counted by the internal circuitry and an interrupt is generated to the main microprocessor. U12 reads the datafrom U5 in 2 bytes: byte one contains the number of complete cycles detected within 122mS, and byte 2 containsthe number of internal clock cycles elapsed for the remainder. U12 performs a comparison of minimum andmaximum values allowed in a look up table and determines if the data is within the decode bandwidth for theprogrammed tone.

In band tone signalling: Audio from the transceiver is also fed to U3B where it is amplified and limited for inputto the commutating switched capacitive filter made up by C23-C26 and P0.4-P0.7 of the microprocessor. Themicroprocessor outputs four identical signals with 90° phase difference on the respective port pins. The resultantwave form will be a function of the difference between the incoming signal frequency and the decode frequencyoutput by the microprocessor. The signal is buffered by U3C and amplified by U3A before being rectified andfiltered by D1 and C2. The resulting DC voltage is compared to the reference voltage by U3D. If the incomingsignal is within the decode bandwidth, the output of U3D will be a logic 1 and read by the microprocessor.

Logic and control: U12 is an Atmel 89C52 microprocessor with flash E²PROM memory. The microprocessorprovides all of the logic and control functions for the repeater including mobile/repeater PTT output, local mobilePTT sense, mobile transmitter activity sense, audio switching, in-band & CTCSS detect, and repeater statusindications via DS4 and DS5 led arrays.

The 89C52 has four 8 bit ports that interface with the rest of the hardware on the controller board; a briefdescription of each port follows:

P0.0-0.3 Channel Selector input; used only on SVR-214 version.

P0.4-0.7 These four lines make up the input to the switched capacitive filter network of C23-C26. Duringreceive mode, the lock tone frequency will be output on each of these lines with a 90° phase differencebetween them at any given time. During transmit mode, these lines are in active and open collector.

P1.0-P1.2 LED data is output on P1.0 line every 10mSec. Data is loaded into shift register U9 8 bits at a timeand is clocked by P1.1. P1.2 latches the data into U9 for display.

P1.3 PLL latch enable output to the RF module. During transmit to receive and receive to transmittransitions, this line is used to latch the serial data into the PLL shift registers. The serial data and clocklines are shared with U10 (E²PROM) U4 (audio processor) and U5 (sub-audio processor).

P1.4 E²PROM chip enable, active high. Data is output to the E²PROM on P1.6 and clocked by P1.5. Datais input from the E²PROM on P1.7. P1.4 will go active during read and write operations with U10.U10 is written to every time the unit is programmed. U10 is read only at power up.


P1.5 Serial clock line output. Serial data that is sent to the PLL, the E²PROM and the audio processor chipsare clocked by each low-high-low transition on this line.

P1.6 Serial data output. Data sent to U10, U4 and U5 are output on this line and clocked by P1.5.

P1.7 Data input to the microprocessor. Serial data is read from U10 (E²PROM) and U5 (sub-audioprocessor) on this line.

P2.0 Lock tone output. Lock tone encode is generated by this pin at power up and during lock tone test mode.All of the queuing tones are also generated by this pin for trunking operation.

P2.1 Lock tone decode input, active high. The output of lock tone decoder U3D is input on this line andchecked during receiver activity. If lock tone is detected, the microprocessor increments its prioritycounter and ceases activity as priority unit.

P2.2 Repeater Tx enable. This line is used to turn on the TX 9V signal to the RF PCB. The output drivesbuffers Q7 and Q6. The output of Q6 switches Q4 on during transmit for TX 9V. RV10 and APCcircuit U13 are used to set the TX 9V level for RF power control.

P2.3 Mobile PTT output, active low. This line is brought low to key the mobile radio during portable-to-baserepeat operations.

P2.4 Mobile COR input. U1A is a threshold detector for the mobile COR input on pin 7 of P1. The outputof U1A is read by the microprocessor on this port to determine if the SVR-200 should repeat base toportable. Polarity of this input is determined by PC programming.

P2.5 Repeater COR input, active low. RSSI output from the RF module is sent to threshold detector U2Dfor comparison with the squelch setting at RV9. R47 and R70 provide hysteresis to prevent chatter.Repeater COR is used to enable the CTCSS decoder circuitry; the microprocessor will not decodethe signal from U5 unless repeater COR is also active.

P2.6 Chip select output for U4 (audio processor), active low. Serial data is sent to U4 on P1.6 and clockedby P1.5. These lines are shared by U5, U10 and the PLL; data is ignored by U4 unless the chip selectline is asserted during data write operations.

P2.7 Chip select output for U5 (sub-audio processor), active low. Serial data is sent to U5 on P1.6 andclocked by P1.5. These lines are shared by U4, U10 and the PLL; data is ignored by U5 unless thechip select line is asserted during data read and write operations.

INT0 External interrupt #0. This line monitors the PLL lock detector output. The line is active high to indicatethe PLL is functioning on frequency during transmit-receive and receive to transmit changes. Theoutput will go briefly unlocked, then revert back to a locked condition. If the PLL does not achievelock within 50mS, the transmitter will be disabled and the OPT LED will flash rapidly to alert the userthat the unit should be brought in for service.

INT1 External interrupt #1 active low. This line is used by U5 to signal the microprocessor that it hascompleted a decode cycle and data can be read. During receiver activity, this line will go activeapproximately every 122 mS in the presence of sub-audio signalling. During transmit mode andreceiver activity without sub-audio signalling, this line will be inactive.


T0 Test input, active low. Shorting J3 puts the microprocessor into test mode for alignment purposes. Ifshorted at power up, the receiver will operate open squelch mode and audio will be heard at the localspeaker port regardless of carrier or tone input to the receiver. Although alignment is normally donewith the RSSI output at TP1, a Sinad reading can be obtained using this mode of the test input. Allother functions of the SVR-200 are disabled in this mode and power will have to be turned off thenon to reset the unit.

If J3 is shorted after power has been applied, the microprocessor will enter the lock tone test mode,key the repeater and send the programmed lock tone for as long as J3 is shorted. Remove the shortfrom J3 to return to normal operation.

T1 On-air detect input. The on-air detect line (P1 pin 9) is used to detect local mic PTT from the mobile,and in trunking mode, this line is used to detect that the mobile transmitter is actually on the air. Theinput is buffered by Q10 and the polarity of the signal is determined by PC programming.

WR Turns the Rx 5V line on or off to the RF PCB.

RD Detects the version of RF PCB installed (UHF only).

TXD Transmit data output for programming. Data is sent to the PC on this line at 300 baud, 8 data bits, 1stop bit and no parity. This line is active only during programming mode.

RXD Receive data input for programming. Data is received from the PC on this line at 300 baud, 8 databits, 1 stop bit and no parity. This line is also used to sense when the programming cable is inserted.If RXD is grounded, the SVR-200 operates in the normal mode. If this line is high, programming modeis entered and the OPT LED is on continuously.

Reset Active high input to reset the microprocessor. U11 provides a 350mSec delayed high signal to this pinduring power up or if the 5V line falls below 4.5VDC.

Xtal The microprocessor uses a 4.032MHz xtal for all of the timing and program execution clock cycles.The output of the on board oscillator also drives the xtal input to U5. The output of U5 xtal oscillatordrives the input of U4.
