VXR-7000U FM REPEATER OPERATING MANUAL 22: LED Indicators AC: This LED glows green during AC operation. DC: This LED glows yellow during DC operation.3: MIC JackThis 8-pin modular jack accepts the microphone input, and provides a standby control line to activatethe transmitter when using the “BASE” mode of operation. This jack also provides a “Hook” controlline, as well as a “Clone Data” line.4: BASE/REPEATER SwitchThis 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. Whilein the “BASE” mode (the green LED is off), you can speak into the microphone to use it as atransceiver. For normal repeater operation, set this switch to the “REPEATER” mode.5: LOCAL/REMOTE SwitchThis 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 thecontrol data programmed into the repeater. While in the “REMOTE” mode, the LED glows green,and the repeater operates according to the control instructions received from an external device(connected to the ACC jack on the rear panel).6: MONITOR SwitchThis 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 glowsteadily; in this condition, only “noise squelch” is active, and any signal present on the channel willbe heard. If you press and hold this switch for more than 2 second, the green LED will blink and thesquelch will open; in this condition, background noise will be heard if no signal is present.7: ACCESSORY SwitchThis switch can be set up for special applications, such as High/Low power selection, as determinedby your Vertex Standard dealer. The LED above it glows green when this function is activated. Forfurther details, contact your Vertex Standard dealer.8: VOL KnobThis control knob adjusts the receiver volume level from the front panel speaker. If desired, thiscontrol knob may be set fully counterclockwise when repeater monitoring is not needed.9: SQL KnobThis control knob selects the noise squelch threshold level. Set it to a position just above the pointwhere the BUSY lamp goes out when no signal is present.10: Channel Selector Buttons (^ and v) Press one of these buttons to select the operating channel.11: Channel Indicator This seven-segment LED indicates the operating channel number.12: ANI DisplayThe ANI LCD (Liquid Crystal Display) indicates the pre-programmed ANI message according to theANI code received.13: TX/BUSY IndicatorThe BUSY indicator glows green when the channel is busy, and the TX indicator glows red when therepeater is transmitting.14: ANI RESET Button (1) ANI Press this button to clear the message on the ANI display, and turn off the LCD backlight.

VXR-7000U FM REPEATER OPERATING MANUAL 3 Press this button again to clear the message on the ANI display, and turn off the LCD backlight.Rear Panel1: EXT SP JackThis 3.5-mm, 2-pin jack provides variable audio output for an external speaker. The audio outputimpedance at this jack is 4ohms ~ 16ohms and level varies according to the setting of the frontpanel’s VOL control.2: TX Antenna JackThis N-type coaxial jack provides the transmitting output signal for connection to the transmittingantenna or TX jack on the duplexer, if used. The output impedance requirement is 50 W.3: RX Antenna JackThis N-type coaxial jack accepts the receiver input signal from the receiving antenna or RX jack onthe duplexer, if used. The input impedance requirement is 50 W.4: ACC JackThis DB-25 connector provides a data interface between the microprocessor in the VXR-7000 andperipheral devices (such as the VX-TRUNK Unit).5: LINE JackThis 8-pin modular jack is used for remote control. It provides TX and RX audio, TX keying, andsquelch status output. The TX and RX audio impedance is 600 W.6: GND TerminalFor best performance and safety, the GND terminal should be connected to a good earth ground usinga short, heavy, braided cable.7: AC JackThis receptacle accepts the AC power cord, which should be connected to the AC mains supply orwall outlet. The AC line voltage must match that for which the repeater is wired.8: BATT TerminalThese terminal posts accept 12~ 15 VDC for operating the repeater from a battery or other DCsource. When operating from AC mains, a small trickle current is present at these terminals tomaintain battery charge. A battery rated for 12 volts, 55 Ah (minimum) is recommended for short-term emergency/backup operation.ACC Connector PortThe VXR-7000 repeater is provided with a 25-pin DB-25F female connector for interconnections toaccessories. Use a DB-25M 25-pin male connector to connect accessories to the repeater. The pins onthe accessory connector are explained in detail as follows:Pin 1: GND Chassis ground for all logic levels and power supply 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 theexternal device’s DC line to prevent damage to the repeater.Pin 3: TX AF IN [Analog Transmitter Input] (Voice Band: 300 ~ 3,000 Hz)Input impedance is approx. 600 W. This audio is injected before the splatter filter stage, so excesssignal input levels are clipped. Use shielded cable to connect to this pin, and connect the shield to GND.Pin 4: TONE IN [Transmitter Input] (Sub-audible Band: 6 ~ 250 Hz) The input is high impedance (approx. 22 ?W). Injecting too high a voltage here causes over-deviationof CTCSS or DCS, degrading performance. Use shielded cable to connect to this pin, connecting theshield to GND.
VXR-7000U FM REPEATER OPERATING MANUAL 4Pin 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 V p-p audio at this pin. The outputimpedance is approx. 600 W, and is extracted before the de-emphasis and squelch circuitry. Useshielded cable to connect to this pin, and connect the shield to GND.Pin 7: GND Chassis ground for all logic levels and power supply return.Pin 8: RSSI [Analog Output]A DC voltage proportional to the strength of the signal currently being received (Receiver SignalStrength Indicator) is provided on this pin. This low impedance output is generated by the receiver IFsub-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 collectoroutput, which can sink approx. 10 mA when active. This signal only switches if the repeater has beenprogrammed for “SIMPLEX” mode. If programmed for “DUPLEX” the signal remains open (highimpedance) at all time.Pin 10: N.C. (No connection.)Pin 11: NSQ DETThis is an open-collector, active-low output capable of sinking about 10 mA. It indicates that thereceiver squelch is open. If the squelch control is properly set, this indicates a carrier on the receiverchannel.Pin 12: EXT PTTThis input is internally pulled up to 5 VDC. When pulled low by an external device, it keys therepeater transmitter while the repeater is operating in the “BASE” mode. Avoid voltage in excess of5 V on this pin, or internal damage to the microprocessor on the repeater CNTL Unit may result.Pin 13: GND Chassis ground for all logic levels and power supply return.Pin 14: GNDChassis ground for all logic levels and power supply 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 selectone of the 16 pre-programmed repeater-operating channels. The logic truth table below shows thecombinations for selecting all 16 channels. In the truth table, “1” represents no connection, and “l”represents a ground connection on the pin. The channel selection logic is not inhibited while thetransmitter is keyed: the repeater will change frequency when instructed, even while transmitting.Avoid voltage in excess of 5 V on these pins or internal damage to the microprocessor on the repeaterCNTL Unit may result.Channel Pin 16(D3) Pin 17(D2) Pin 18(D1) Pin 19(D0)1 1 1 1 12 1 1 1 03 1 1 0 14 1 1 0 05 1 0 1 16 1 0 1 07 1 0 0 1

This digitaldata signal is injected before transmitter pre-emphasis and limiting stage, so excess signal inputlevels are clipped.Pin 25: TXD HI [Digital Input for the DATA Communications]This pin is intended to be used as a high-speed digital data signal input to the repeater. This digitaldata signal is injected after transmitter splatter filter stage.CLINE Interface PortThe VXR-7000 is provided with an 8-pin modular jack for line interfacing applications. A WesternElectric modular-type RJ45 plug should be used to connect to this jack. The LINE jack pin-out isshown below.Note that there are both 4-line and 8-line types of modular 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 alllines. In accordance with standard telecommunications interface, the line connections on the LINEinterface 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 asignal exceeding the receiver squelch appears on the receiver channel (with correct CTCSS tone orDCS code, if enabled). The RX SQ(Œ) 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 therepeater is set to the BASE mode (the REPEATER LED is turned off) and keyed either by the TXKEY input signal (see below), or by the EXT PTT signal on pin 12 of the rear panel’s 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 receivedsignal strength is above the squelch threshold.
VXR-7000U FM REPEATER OPERATING MANUAL 6As shipped from the factory, a 1-kHz receiver signal with standard deviation gives Œ10 dBm on theline, but this can be varied by VR4002 and S4001 (on the repeater’s 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 thesepins turns on the opto-isolator and keys the transmitter.The TX KEY (+) pin is the anode of the opto-isolator, and RX SQ(Œ) is the cathode of the opto-isolator.InstallationAntenna ConsiderationsRepeater operation without a duplexer requires that two antennas be installed, one for receiving andone for transmitting, so that the receiving antenna does not absorb energy from the transmittingantenna. There are a number of ways to do this, depending on the TX/RX frequency separation, andon the locations available for antenna mounting. If a duplexer is used, a single antenna suffices forboth transmitting and receiving. If using a reduced-size duplexer, a six-cavity model (minimum) isrecommended. Vertex Standard recommends the use of the duplexer. For further details, contact yourVertex Standard dealer.Regardless of the above choice, it is of paramount importance that the antenna(s) be mounted as highand in the clear as possible, preferably within line-of-sight to all repeater users. Furthermore, lossesin the feedline(s) must be minimized, so the feedline(s) should be high quality, and as short aspossible. If a long feedline is necessary, use coaxial “hardline”, cable to reduce losses.Repeater antennas should have impedance of 50 ohms at the operating frequency. When separatereceives and transmits antennas are used, high-Q narrow-band types may serve to minimizeinteraction. However, when a single antenna is used with a duplexer, it should be a low-Q wide-bandtype.NEVER TRANSMIT WITHOUT HAVING ATRANSMIT ANTENNA CONNECTED TOTHE TX ANTENNA JACK OF THEREPEATER.AC Power Supply Voltage SelectionEach repeater is wired for a particular AC mains voltage between 100 and 253 VAC. This should beindicated by a label near the AC jack on the rear panel. If no label is present, or if the AC voltage onthe label is different from the local AC line, check the wiring inside the Switching Regulator Unit ofthe 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 thevoltage is changed from 100 VAC (100-127 VAC) to 200 VAC (207-253 VAC), or vice-versa. Use a5-amp fuse for 100 VAC, or a 3-amp fuse for the 200 VAC.DC Power Supply BackupFor uninterrupted operation during power failures, a 12-volt rechargeable type battery (55-Ah ormore recommended) may be connected to the BATT terminal posts on the rear panel. While therepeater is operating from the AC source, a slight charging current will maintain battery charge. In
VXR-7000U FM REPEATER OPERATING MANUAL 7the event of an AC power outage, the automatic power control circuit will automatically switch therepeater to the backup battery, and operation will not be interrupted.After prolonged operation from the battery, it should be disconnected from the repeater and rechargedseparately before re-connecting, as the trickle charge is not sufficient for recharging a completelydischarged battery.Never reapply AC power to the repeater with a discharged battery connected, as the DC startupcurrent can damage the repeater and battery.While operating from a battery or DC supply, the repeater requires approximately 7 amperes at 12Volts during transmit.Equipment LocationWhile the operating temperature range of the repeater is quite broad, the best location is one in whichthe air temperature does not approach the extremes of the specified range, and one that does notchange rapidly. Make sure to allow for free airflow 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 shortenthe useful life of the equipment. Try to locate the repeater in an environment that is also comfortablefor service personnel, if possible.Changing Switching Regulator unit AC Mains Jumper WiringBefore attempting this jumper wire change, remove the AC power cord from the AC jack on the rearpanel.*Referring to Figure 1, remove the 14 screws affixing the top and bottom covers of the repeater, andremove the covers.*Remove the eight screws affixing the shield cover for the FILTER Unit, and remove the cover (seeFigure 1).*Disconnect all wires and connectors from the FILTER Unit, then remove the six screws affixing theSwitching Regulator Unit, and remove it (the Switching Regulator Unit is mounted with the FILTERUnit: Figure 2).*Referring to Figure 3, remove the four screws and remove the heatsink from the Switching RegulatorUnit.*Referring to Figure 4, perform the correct jumper wiring on the Switching Regulator Unit for the ACMains voltage used in your area (100-127 VAC or 207-253 VAC).*Replace the heatsink onto the Switching Regulator Unit, then replace the Switching Regulator Unitonto the chassis, and connect all wires and connectors to the FILTER Unit.*Replace the AC fuse (FH6001) on the FILTER Unit according to the AC Mains voltage range:100 VAC (100-127 VAC): 5A200 VAC (207-253 VAC): 3A.*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 FILTERUnit. Do not replace with a slow-blow type fuse.CE-27 Programming Software InstructionWith the CE-27 Programming Software, you can quickly and easily program the Vertex VXR-7000repeater’s channels and configuration from your personal computer.
