Introduction

The VXR-7000 is commercial quality 50-watt FM repeater designed to provide reliable, continuous­duty two-way communications over a wide range of environmental conditions.
Designed to be a stylish base station, with high-grade components utilized throughout, the VXR-7000
utilizes the latest computer-aided design and manufacturing processes to ensure a high level of
reliability for users. Important channel frequency data is stored in EEPROM, and is easily
programmable by a Servicing Technician or Dealer using an IBM compatible personal computer and
the VPL-1 Programming Cable and CE-27 Software.
Please take a few minutes to read this manual carefully. The information presented here will allow you
to derive maximum performance from your VXR-7000. After reading it, keep this manual handy for
quick reference, in case questions arise later on.

Important Note: Internal service work, programming, and accessory installations should only be
performed by your authorized Vertex Dealer. Dangerous conditions and/or possibly illegal operation
may result from improper setup, programming, or internal modifications.

Controls & Connectors

Front Panel
1: POWER Switch

This is the main power switch for the repeater.

VXR-7000U FM REPEATER OPERATING MANUAL 1

2: LED Indicators

AC: This LED glows green during AC operation.
DC: This LED glows yellow during DC operation.

3: MIC Jack

This 8-pin modular jack accepts the microphone input, 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.

4: 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 “REPEATER” mode.

5: 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 instructions received from an external device
(connected to the ACC jack on the rear panel).

6: 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 second, the green LED will blink and the
squelch will open; in this condition, background noise will be heard if no signal is present.

7: 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
further details, contact your Vertex Standard dealer.

8: 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 repeater monitoring is not needed.

9: SQL Knob

This control knob selects the noise squelch threshold level. Set it to a position just above the point
where 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 Display

The ANI LCD (Liquid Crystal Display) indicates the pre-programmed ANI message according to the
ANI code received.

13: TX/BUSY Indicator

The BUSY indicator glows green when the channel is busy, and the TX indicator glows red when the
repeater 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.
(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
1: EXT SP Jack

This 3.5-mm, 2-pin jack provides variable audio output for an external speaker. The audio output
impedance at this jack is 4ohms ~ 16ohms and level varies according to the setting of the front
panel’s VOL control.

2: TX Antenna Jack

This N-type coaxial jack provides the transmitting output signal for connection to the transmitting
antenna or TX jack on the duplexer, if used. The output impedance requirement is 50 W.

3: 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.

4: ACC Jack

This DB-25 connector provides a data interface between the microprocessor in the VXR-7000 and
peripheral devices (such as the VX-TRUNK Unit).

5: LINE Jack

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.

6: GND Terminal

For best performance and safety, the GND terminal should be connected to a good earth ground using
a short, heavy, braided cable.

7: 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.

8: BATT Terminal

These terminal posts accept 12~ 15 VDC for operating the repeater from a battery or other DC
source. When operating from AC mains, a small trickle current is present at these terminals to
maintain battery charge. A battery rated for 12 volts, 55 Ah (minimum) is recommended for short­term emergency/backup operation.

ACC Connector Port

The VXR-7000 repeater is provided with a 25-pin DB-25F female connector for interconnections to
accessories. 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 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 the
external 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 excess
signal 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-deviation
of CTCSS or DCS, degrading performance. Use shielded cable to connect to this pin, connecting the
shield to GND.
