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 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.
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 instructions 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 second, 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 further 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 repeater monitoring is not needed.
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.

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 4 Ω ~ 16 Ω, and level varies
according to the setting of the front panel’s VOL control.
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 Ω.
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 Ω.
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).
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 Ω.
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 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 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 DB25F 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 Ω. 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 kΩ). 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.
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 impedance is approx. 600 Ω, 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 supply return.
Pin 8: RSSI [Analog Output]
A DC voltage proportional to the strength of the signal 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 output which can sink approx. 10 mA when active. This
signal only switches if the repeater has been programmed for “SIMPLEX” mode. If programmed
for “DUPLEX,” the signal remains open (high impedance) 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 Connector Port
Pin 13: GND
Chassis ground for all logic levels and power supply return.
Pin 14: GND
Chassis 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 select
one of the 16 pre-programmed repeater operating
channels. The logic truth table below shows the combinations 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
frequency when instructed, even while transmitting.
Avoid voltage in excess of 5 V on these pins or internal damage to the microprocessor on the repeater
CNTL Unit may result.

Pin 21: A-OUTPUT [Logic Output] (Active Low)
This open collector logic output is pulled low when
the front panel’s ACCESSORY key is turned on. It
can sink approx. 10 mA when active.
Pin 22: RXD LOW
[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 deemphasis 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 digital 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 digital 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 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 all lines. In accordance with
standard telecommunications interface, the line connections 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
receiver channel (with correct CTCSS tone or DCS
code, if enabled). The RX SQ(–) pin is the emitter,
and RX SQ(+) is the collector.
Maximum Voltage: 20 V, Maximum Current: 7 mA.
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 repeater 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 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 received signal 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 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 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.
Maximum Voltage: 20 V, Maximum Current: 4 mA.

Installation
Antenna Considerations
Repeater operation without a duplexer requires that two
antennas be installed, one for receiving and one for
transmitting, so that the receiving antenna does not absorb energy from the transmitting antenna. There are a
number of ways to do this, depending on the TX/RX
frequency separation, and on the locations available for
antenna mounting. If a duplexer is used, a single antenna suffices for both transmitting and receiving. If
using a reduced-size duplexer, a six-cavity model (minimum) 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 importance 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
necessary, use coaxial “hardline” cable to reduce losses.
Repeater antennas should have an impedance of 50 Ω
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.
AC Power Supply Voltage Selection
Each repeater is wired for a particular AC mains voltage 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 (207253 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 recommended) 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 maintain battery charge. In the event of an AC power outage, the automatic power control circuit will automatically switch the repeater to the backup battery, and operation 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
sufficient for recharging a completely discharged battery.
Never reapply AC power to the repeater with a discharged battery connected, as the DC startup current
can damage the repeater and battery.
While operating from a battery or DC supply, the repeater requires approximately 7 amperes at 12 Volts during 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
specified 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 personnel, if possible.

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.
Referring to Figure 1, remove the 14 screws affixing
the top and bottom covers of the repeater, and remove the covers.
Remove the eight screws affixing the shield cover
for the FILTER Unit, and remove the cover (see Figure 1).
Disconnect all wires and connectors from the FIL-
TER Unit, then remove the six screws affixing the
Switching Regulator Unit, and remove it (the Switching Regulator Unit is mounted with the FILTER Unit:
Figure 2).
Referring to Figure 3, remove the four screws and
remove the heatsink from the Switching Regulator
Unit.
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).
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.
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.
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.

CE27 Programming Software Instruction
With the CE27 Programming Software, you can quickly
and easily program the Vertex Standard VXR-7000
repeater’s channels and configuration from your personal computer. Channel data programming format is
identical for VHF and UHF repeaters. In the event of an
accidental memory failure, repeater memory and configuration data may be re-loaded in a matter of minutes.
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 FIF-10A (or FIF-12) + CT-104A USB Programming
Interface to the computer’s USB port and the VXR-7000’s
MIC jack.
Then it will be safe to restart the computer; turning off
the equipment during interconnection avoids the potential for damage to the electronics caused by voltage
spikes.
Insert the distribution diskette into your 3½” drive (after 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 3½” drive (usually “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 introductory screen will appear, and you may press any
key to enter the main screen.
Choose the “Help” contents option (F1) from the
program’s Menu for assistance with channel programming or setting of parameters.
Important Note!
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 distribution diskette in a safe place in case you
need to make another copy of it at a later date.
Before creating the programming data for your
VXR-7000 via the CE27 programming software,
upload the current factory hardware environment data from the VXR-7000, using the [F5]
(ReadRom) command. Use this data profile to
create the programming data for this repeater.
