VXR-7000 FM REPEATER OPERATING MANUAL 1 Controls & Connectors Front Panel POWER Switch This is the main power switch for the repeater. LED Indicators AC: This LED glows green during AC operation. DC: This LED glows yellow during DC operation. MIC Jack This 8-pin modular jack accepts the microphone in-

put, and provides a standby control line to activate the transmitter when using the BASE mode of operation. This jack also provides a Hook control line, as well as a Clone Data line. BASE/REPEATER Switch This switch toggles the operating mode between the REPEATER mode and the BASE transceiver mode. When the REPEATER mode is selected, the LED above it glows green. While in the BASE mode (the green LED is off), you can speak into the microphone to use it as a transceiver. For normal repeater operation, set this switch to the RE-

PEATER mode. LOCAL/REMOTE Switch This switch toggles the control mode between the REMOTE mode and LOCAL mode. When the LOCAL mode is selected, the LED above it is off, and the repeater operates according to the control data programmed into the repeater. While in the REMOTE mode, the LED glows green, and the repeater operates according to the control instruc-

tions received from an external device (connected to the ACC jack on the rear panel). MONITOR Switch This switch selects the Squelch (receiver mute) mode. When the green LED above it is off, Tone or Coded squelch is active. When you press this switch momentarily, the green LED will glow steadily;

in this condition, only noise squelch is active, and any signal present on the channel will be heard. If you press and hold this switch for more than 2 sec-

ond, the green LED will blink and the squelch will open; in this condition, background noise will be heard if no signal is present. ACCESSORY Switch This switch can be set up for special applications, such as High/Low power selection, as determined by your Vertex Standard dealer. The LED above it glows green when this function is activated. For fur-

ther details, contact your Vertex Standard dealer. VOL Knob This control knob adjusts the receiver volume level from the front panel speaker. If desired, this control knob may be set fully counterclockwise when re-

peater monitoring is not needed. SQL Knob This control knob selects the noise squelch thresh-

old level. Set it to a position just above the point where the BUSY lamp goes out when no signal is present. Channel Selector Buttons (p and q) Press one of these buttons to select the operating channel. 2 VXR-7000 FM REPEATER OPERATING MANUAL Channel Indicator This seven-segment LED indicates the operating channel number. ANI Display The ANI LCD (Liquid Crystal Display) indicates the pre-programmed ANI message according to the ANI code received. TX/BUSY Indicator The BUSY indicator glows green when the channel is busy, and the TX indicator glows red when the repeater is transmitting. Controls & Connectors ANI RESET Button

(1) ANI Press this button to clear the message on the ANI display, and turn off the LCD backlight.

(2) ENI Press this button to turn off the Alert tone. Press this button again to clear the message on the ANI display, and turn off the LCD backlight. Rear Panel EXT SP Jack LINE Jack This 3.5-mm, 2-pin jack provides variable audio output for an external speaker. The audio output im-

pedance at this jack is 4 W

, and level varies according to the setting of the front panels VOL con-

trol.

~ 16 W TX Antenna Jack This N-type coaxial jack provides the transmitting output signal for connection to the transmitting an-

tenna or TX jack on the duplexer, if used. The out-

put impedance requirement is 50 W

. RX Antenna Jack This N-type coaxial jack accepts the receiver input signal from the receiving antenna or RX jack on the duplexer, if used. The input impedance requirement is 50 W

. ACC Jack This DB-25 connector provides a data interface be-

tween the microprocessor in the VXR-7000 and pe-

ripheral devices (such as the VX-TRUNK Unit). This 8-pin modular jack is used for remote control. It provides TX and RX audio, TX keying, and squelch status output. The TX and RX audio impedance is 600 W

. GND Terminal For best performance and safety, the GND terminal should be connected to a good earth ground using a short, heavy, braided cable. AC Jack This receptacle accepts the AC power cord, which should be connected to the AC mains supply or wall outlet. The AC line voltage must match that for which the repeater is wired. BATT Terminal These terminal posts accept 12~ 15 VDC for operat-

ing the repeater from a battery or other DC source. When operating from AC mains, a small trickle cur-

rent is present at these terminals to maintain bat-

tery charge. A battery rated for 12 volts, 55 Ah (mini-

mum) is recommended for short-term emergency/

backup operation. Never short-circuit these terminal while operating from AC mains. VXR-7000 FM REPEATER OPERATING MANUAL 3 ACC Connector Port The VXR-7000 repeater is provided with a 25-pin DB-

25F female connector for interconnections to accesso-

ries. Use a DB-25M 25-pin male connector to connect accessories to the repeater. The pins on the accessory connector are explained in detail as follows:

Pin 1: GND Chassis ground for all logic levels and power sup-

ply return. Pin 2: +13.8 V [Power Supply]

This pin provides 13.8 Volts, 1.0 A, regulated DC from the repeater supply. Use a 1 A fuse in the exter-

nal devices DC line to prevent damage to the re-

peater. Pin 3: TX AF IN [Analog Transmitter Input]

(Voice Band: 300 ~ 3,000 Hz) Input impedance is approx. 600 W

. This audio is in-

jected before the splatter filter stage, so excess sig-

nal input levels are clipped. Use shielded cable to connect to this pin, and con-

nect the shield to GND. Pin 4: TONE IN [Transmitter Input]

(Sub-audible Band: 6 ~ 250 Hz) The input is high impedance (approx. 22 kW

). In-

jecting too high a voltage here causes over-devia-

tion of CTCSS or DCS, degrading performance. Use shielded cable to connect to this pin, connecting the shield to GND. Pin 5: N.C. (No connection.) Pin 6: DISC OUT [Analog Output]

(Wide-Band: 0 ~ 3,000 Hz) Received signals with standard deviation produce approx. 1 Vp-p audio at this pin. The output imped-

ance is approx. 600 W

, and is extracted before the de-emphasis and squelch circuitry. Use shielded cable to connect to this pin, and connect the shield to GND. Pin 7: GND Chassis ground for all logic levels and power sup-

ply return. Pin 8: RSSI [Analog Output]

A DC voltage proportional to the strength of the sig-

nal currently being received (Receiver Signal Strength Indicator) is provided on this pin. This low impedance output is generated by the receiver IF sub-system and buffered by an internal op-amp. Typical voltages are graphed as follows:

Pin 9: COAX. SW [Logic Output (Active Low)]

This output is intended for controlling an external coaxial switching relay. It is an open collector out-

put which can sink approx. 10 mA when active. This signal only switches if the repeater has been pro-

grammed for SIMPLEX mode. If programmed for DUPLEX, the signal remains open (high im-

pedance) at all time. Pin 10: N.C. (No connection.) Pin 11: NSQ DET This is an open-collector, active-low output capable of sinking about 10 mA. It indicates that the receiver squelch is open. If the squelch control is properly set, this indicates a carrier on the receiver channel. Pin 12: EXT PTT This input is internally pulled up to 5 VDC. When pulled low by an external device, it keys the repeater transmitter while the repeater is operating in the BASE mode. Avoid voltage in excess of 5 V on this pin, or internal damage to the microprocessor on the repeater CNTL Unit may result. ACC Jack DB-25 Pin Numbering 4 VXR-7000 FM REPEATER OPERATING MANUAL Pin 13: GND Pin 20: GND Chassis ground for all logic levels and power sup-

ply return. Chassis ground for all logic levels and power sup-

ply return. ACC Connector Port Pin 14: GND Chassis ground for all logic levels and power sup-

ply return. Pin 15: N.C. (No connection.) Pin 16, 17, 18, & 19: REMOTE CH DATA

[Logic Inputs D3, D2, D1, and D0] (Active Low) These inputs are internally pulled up to 5-V DC. When pulled low by an external device, they select one of the 16 pre-programmed repeater operating channels. The logic truth table below shows the com-

binations for selecting all 16 channels. In the truth table, 1 represents no connection, and 0 represents a ground connection on the pin. The channel selection logic is not inhibited while the transmitter is keyed: the repeater will change fre-

quency when instructed, even while transmitting. Avoid voltage in excess of 5 V on these pins or inter-

nal damage to the microprocessor on the repeater CNTL Unit may result. Channel 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Pin 16

[Digital Output for DATA Communications]

(300 ~ 3,000 Hz) This pin is an output for low speed receiving data signals, with the data being extracted after the de-

emphasis and low pass filter stages. Pin 23: RXD HI

[Digital Output for DATA Communications]

This pin is an output for high speed receiving data signals, with the data being extracted immediately after the discriminator prior to any de-emphasis). Pin 24: TXD LOW

[Digital Input for DATA Communications]

(300 ~ 3,000 Hz) This pin is intended to be used as a low speed digi-

tal data signal input to the repeater. This digital data signal is injected before transmitter pre-emphasis and limiting stage, so excess signal input levels are clipped. Pin 25: TXD HI

[Digital Input for the DATA Communications]

This pin is intended to be used as a high speed digi-

tal data signal input to the repeater. This digital data signal is injected after transmitter splatter filter stage. VXR-7000 FM REPEATER OPERATING MANUAL 5 LINE Interface Port The VXR-7000 is provided with an 8-pin modular jack for line interfacing applications. A Western Electric modular-type RJ45 plug should be used to connect to this jack. The LINE jack pin-out is shown below. Note that there are both 4-line and 8-line types of modu-

lar plugs. If a 4-line modular plug is used, only the LINE OUT and LINE IN connections will be made. An 8-line plug is required to access all lines. In accordance with standard telecommunications interface, the line connec-

tions on the LINE interface jack are impedance balanced, and are described as follows. Pins 1 & 2: [RX SQ(+), RX SQ()]

An opto-isolator is provided to facilitate E (EAR) signaling. The opto-isolator comes on when a signal exceeding the receiver squelch appears on the re-

ceiver channel (with correct CTCSS tone or DCS code, if enabled). The RX SQ() pin is the emitter, and RX SQ(+) is the collector. Pins 3 & 4: [LINE IN (Tx Line Audio)]

Analog signals between 300 and 3000 Hz supplied to this pair are fed to the transmitter when the re-

peater is set to the BASE mode (the REPEATER LED is turned off) and keyed either by the TX KEY input signal (see below), or by the EXT PTT signal on pin 12 of the rear panels ACC jack. Standard deviation is obtained with a line level of 10 dBm. Pins 5 & 6: [LINE OUT (Rx Line Audio)]

Receiver audio is available from this pair, subject to internal CTCSS or DCS decode if the received sig-

nal strength is above the squelch threshold. As shipped from the factory, a 1-kHz receiver signal with standard deviation gives 10 dBm on the line, but this can be varied by VR4002 and S4001 (on the repeaters CNTL Unit). Pins 7 & 8 [TX KEY(+), TX KEY()]

An opto-isolator is provided to facilitate M (MIC) signaling. That is, a voltage presented to these pins turns on the opto-isolator and keys the transmitter. The TX KEY(+) pin is the anode of the opto-isolator, and RX SQ() is the cathode of the opto-isolator. LINE Jack Modular Jack Pin Numbering 6 VXR-7000 FM REPEATER OPERATING MANUAL Antenna Considerations Repeater operation without a duplexer requires that two antennas be installed, one for receiving and one for trans-

mitting, so that the receiving antenna does not absorb energy from the transmitting antenna. There are a num-

ber of ways to do this, depending on the TX/RX fre-

quency separation, and on the locations available for antenna mounting. If a duplexer is used, a single an-

tenna suffices for both transmitting and receiving. If using a reduced-size duplexer, a six-cavity model (mini-

mum) is recommended. Vertex Standard recommends the use of the duplexer. For further details, contact your Vertex Standard dealer. Regardless of the above choice, it is of paramount im-

portance that the antenna(s) be mounted as high and in the clear as possible, preferably within line-of-sight to all repeater users. Furthermore, losses in the feedline(s) must be minimized, so the feedline(s) should be high quality, and as short as possible. If a long feedline is nec-

essary, use coaxial hardline cable to reduce losses. Repeater antennas should have an impedance of 50 W at the operating frequency. When separate receive and transmit antennas are used, high-Q narrow-band types may serve to minimize interaction. However, when a single antenna is used with a duplexer, it should be a low-Q wide-band type. NEVER TRANSMIT WITHOUT HAVING A TRANSMIT ANTENNA CONNECTED TO THE TX ANTENNA JACK OF THE REPEATER. Installation AC Power Supply Voltage Selection Each repeater is wired for a particular AC mains volt-

age between 100 and 253 VAC. This should be indicated by a label near the AC jack on the rear panel. If no label is present, or if the AC voltage on the label is different from the local AC line, check the wiring inside the Switching Regulator Unit of the repeater, and change the connections (and label) if necessary, as shown next page. Changing the AC input voltage wiring also requires changing the fuse on the FILTER Unit if the voltage is changed from 100 VAC (100-127 VAC) to 200 VAC (207-

253 VAC), or vice-versa. Use a 5-amp fuse for 100 VAC, or a 3-amp fuse for the 200 VAC. DC Power Supply Backup For uninterrupted operation during power failures, a 12 volt rechargeable type battery (55-Ah or more rec-

ommended) may be connected to the BATT terminal posts on the rear panel. While the repeater is operating from the AC source, a slight charging current will main-

tain battery charge. In the event of an AC power out-

age, the automatic power control circuit will automati-

cally switch the repeater to the backup battery, and op-

eration will not be interrupted. After prolonged operation from the battery, it should be disconnected from the repeater and recharged separately before re-connecting, as the trickle charge is not suffi-

cient for recharging a completely discharged battery. Never reapply AC power to the repeater with a dis-

charged battery connected, as the DC startup current can damage the repeater and battery. While operating from a battery or DC supply, the re-

peater requires approximately 7 amperes at 12 Volts dur-

ing transmit. Equipment Location While the operating temperature range of the repeater is quite broad, the best location is one in which the air temperature does not approach the extremes of the speci-

fied range, and one that does not change rapidly. Make sure to allow for free air flow around the heatsink on the rear apron at all times. In warm climates, the repeater should not be sealed in a small closed room. Protect the repeater from wind and rain, and extremes in temperature or humidity that may shorten the useful life of the equipment. Try to locate the repeater in an environment that is also comfortable for service person-

nel, if possible. VXR-7000 FM REPEATER OPERATING MANUAL 7 Installation Changing Switching Regulator unit AC Mains Jumper Wiring Before attempting this jumper wire change, remove the AC power cord from the AC jack on the rear panel. r Referring to Figure 1, remove the 14 screws affixing the top and bottom covers of the repeater, and re-

move the covers. r Remove the eight screws affixing the shield cover for the FILTER Unit, and remove the cover (see Fig-

ure 1). r Disconnect all wires and connectors from the FIL-

TER Unit, then remove the six screws affixing the Switching Regulator Unit, and remove it (the Switch-

ing Regulator Unit is mounted with the FILTER Unit:

Figure 2). r Referring to Figure 3, remove the four screws and remove the heatsink from the Switching Regulator Unit. r Referring to Figure 4, perform the correct jumper wiring on the Switching Regulator Unit for the AC Mains voltage used in your area (100-127 VAC or 207-253 VAC). r Replace the heatsink onto the Switching Regulator Unit, then replace the Switching Regulator Unit onto the chassis, and connect all wires and connectors to the FILTER Unit. r Replace the AC fuse (FH6001) on the FILTER Unit according to the AC Mains voltage range:

100 VAC (100-127 VAC): 5A 200 VAC (207-253 VAC): 3A. r Replace the shield cover and replace the top and bottom covers. This completes the wiring change. Important!: If you change the AC voltage range, you must also change the AC fuse on the FILTER Unit. Do not replace with a slow-blow type fuse.

sonal computer. Channel data programming format is identical for VHF and UHF repeaters. In the event of an accidental memory failure, repeater memory and con-

figuration data may be re-loaded in a matter of min-

utes. The CE27 Programming Software diskette contains the following files:

CE27.EXE CE27.HLP Before connecting the VXR-7000 for programming, turn off both the computer and the VXR-7000. Now connect the VPL-1 Connection Cable to the computers serial port and the VXR-7000. Then it will be safe to restart the computer; turning off the equipment during interconnection avoids the poten-

tial for damage to the electronics caused by voltage spikes. Insert the distribution diskette into your 3 drive (af-

ter booting DOS), and make a copy of the diskette; use the distribution diskette for archive purposes, and use the disk copy for programming. Place the CE27 (copy) diskette into your 3 drive (usu-

ally Drive A), and log onto this drive by typing A:

[ENTER], then load the contents of the CE27 diskette into a directory named CE27, using the COPY command (e.g. COPY A:*.* C:\CE27). Now type CE27 [ENTER] to start the program. The in-

troductory screen will appear, and you may press any key to enter the main screen. Choose the Help contents option (F1) from the programs Menu for assistance with channel program-

ming or setting of parameters. Important Note!

r Do not run the CE27 programming software di-

rectly from the original distribution diskette. Copy the programming software to your computer's hard disk, then run the software from the hard disk only. Keep the original dis-

tribution diskette in a safe place in case you need to make another copy of it at a later date. r Before creating the programming data for your VXR-7000 via the CE27 programming software, upload the current factory hardware environ-

ment data from the VXR-7000, using the [F5]

(ReadRom) command. Use this data profile to create the programming data for this repeater.

Please refer to the operating manual for your Duplexer for details regarding maximum power input, TX/RX con-

nector locations, etc) before installing the Antenna Duplexer. Be certain to observe and comply with the specifications for frequency separation and maximum transmitter power for the duplexer connected to the VXR-7000, particularly when using the VXD-40xx internal duplexer. When the VXD-40xx is used, the frequency separation must be 5 MHz (minimum) to 10 MHz (maximum), and the maximum transmitter power output allowed is 40 Watts. If the VXR-7000 output power (50 Watts) is in excess of the range of the duplexer's capability, you may reduce the TX output power of the VXR-7000 before installing the Antenna Duplexer, using the following procedure:

1. Connect the VXR-7000s TX antenna port to a watt-

meter and dummy load (the duplexer must not be connected at this point). Connect any Vertex Stan-

dard microphone to the MIC jack, and place the BASE/REPEATER switch in the BASE position. Select Channel 1 for alignment purposes. 2. Press and hold in the ACCESSORY switch for two seconds to enter the adjustment mode. The channel number will begin to blink. 3. Press and hold in the PTT key on the microphone. The display will indicate Po while transmitting. Observe the power output as indicated on the watmeter. 4. Press the p (UP: increment) or q (DOWN: decre-

ment) button (to the right of the channel display) repeatedly to adjust the TX output power to 40 Watts

(or less) while holding in the PTT key. 5. Once the desired power level has been obtained, re-

lease the PTT key. Now press and hold in the AC-

CESSORY button for at least two seconds to save the new setting and exit to the normal operation. 6. Repeat steps 2. through 5. (above) for any other chan-

nels (2 through 16) if they are to be used. 7. Re-test each channel in the normal operating mode to confirm the proper power output. You may now disconnect all test equipment. 8. The duplexer may now be installed. The above procedure should only be performed by your Authorized Vertex Standard Dealer or a qualified radio technician, in order to ensure accurate calibration. Please consult with your Authorized Vertex Standard Dealer for assistance with procurement of a suitable duplexer. 14 VXR-7000 FM REPEATER OPERATING MANUAL Duplexer Installation Installations 1. Remove the 14 screws affixing the top and bottom covers of repeater, and remove the covers (Figure 1). 2. Turn the repeater upside down. 3. Referring to Figure 2, remove the upper screw in either side of the front panel, and loosen the lower screw in either side of the front panel, then slide the front panel forward slightly. 4. Remove the coaxial cables connected to the TX and 5. RX antenna jacks of the repeater. Install the duplexer into the compartment on the bottom side of the repeater, using the four screws and antenna cable provided in the CT-68 Hardware Kit (Figure 3). Some duplexers may not line up with the threaded mounting holes in the repeater's chas-

sis. In this case, use the supplemental mounting brackets supplied with the CT-68 Hardware Kit (Fig-

ure 4). 7. 6. Connect the optional Antenna Cable CT-68 between the TX antenna jack of the repeater and ANT (cen-

ter) jack of the duplexer. If your repeaters Tx/Rx frequency relationship is upper shift type (TXf > RXf), connect the coaxial cable from the RX Unit to the LOW PASS jack of the duplexer and connect the coaxial cable from the PA Unit to the HIGH PASS jack of the duplexer. If your repeaters Tx/Rx frequency relationship is lower shift type (TXf < RXf), connect the coaxial cable from the RX Unit to the HIGH PASS jack of the duplexer and connect the coaxial cable from the PA Unit to the LOW PASS jack of the duplexer. Note: Route the TX coaxial cable from the PA Unit as far as possible from the RX coaxial cable from the RX Unit. 8. Duplexer installation is now complete. Replace the front panel back into place, and replace the top and bottom covers.
