Pin 21; A-OUTPUT [Logic Output] (Active Law)
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 (typically 1200 bps), with the data being ex-
tracted after the de-emphasis and low pass filter
stages.
Pin 3: RXD HI
[Digital Output for DATA Communications]
(M1115 kHz)
This pin is an output for high speed receiving data
signals (typically 9600 bps), with the data being ex-
h'acted 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 (typically 1200
bps). This digital data signal is injected before trans-
mitter pre—emphasis and limiting stage, soacess sig-
nal input levels are clipped.
Pin 25: TXD HI
[Digital Input for the DATA Communicau'ons]
(0 ~ 5 kHz)
This pin is intended to be used as a high speed digi-
tal data signal input to the repeater (typically 9600
bps). This digital data signal is injected after trans-
mitter splatter filter stage.
LINE Interface Port
’
The VXR-7000 is provided with an S—pin modular jack
for line interfacing applications. A Western Electric"
modular-type Rl45 plug should be used to connect to
this jack. The LINE jack pin-out is siiown below.
Note that there are both 4-line and B—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 B-line
plug is required to access all lines. In accordance with
standard telecommunications interface, Hie line connec-
tions on the LINE interface jack are impedance balanced,
and are described as follows.
Pins 1 6: 2: [RX SQ(+), RX SQ(—)]
An opto—isolator is provided to facilitate E (EAR)
signaling, The opto-isolator come on when a signal
exceeding the receiver squelch appears on the re-
ceiver channel (with correct CI'CSS tone or DCS
code, if enabled), The RX SQ(—) pin is the emitter,
and RX SQ(+) is the collector.
Pins 3 & 4: [LINE IN (Tr 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 l’l'l' signal on pin
<<23?>> of the rear panel’s ACC jack, Full system
deviation is obtained with a line level of —10 dBm,
Pins 5 5: 6: [LINE OUT (Rx Line Audio)!
Receiver audio is available from this pair, subject to
internal CT CSS or DCS decode if the received sig-
nal strength is above the squelch threshold.
As shipped from file factory, a ‘l-kHz receiver signal
with full system deviation gives —10 dBm on the line,
but this can be varied over the range -55 dBm to
+10 dBm by VR4002 and 54001 (on the repeater‘ s
CNTL Unit),
Pins 7 a: s [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 K'EY(+) pin is the anode of the opto-isolator,
and RX SQ(—) is the cathode of the opto-isolator.

Installation
Antenna Considerations
Repeater operation without a duplexer requirs that two
antennas be installed, one for r_eceiving 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. Yasu/ Vertex recommends the
use of the 77? duplexer. For further details, contact your
Yaesu/ Vertex 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 narrowAband 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 WITHOHT HAVING A
TRANSIVHT ANTENNA CONNECTED TO THE
TXANTENNA LACK OF THE REPEATER.
AC Power Supply Voltage Selection
Each repeater is wired for a particular AC mains volt-
age between 100 and 234 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 on the REC Unit
of the repeater, and change the connections (and label)
if necmsary, as shown below.
Changing the AC input voltage wiring also requires
changing the fuse on the FILTER Unit if the voltage is
changed from 100 VAC (100-117 VAC) to 200 VAC (200—
m VAC), or vice-versa. Use a ??-amp fuse for 100 VAC,
or a .7?-amp fuse for the VAC.
DC Power Supply Backup
For uninterrupted operation during power failurs, 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 but'tery connected, as the DC stormy current
can damage the repeater and battery.
While operating from a battery or DC supply, the re-
peater requires approximately 7.7 amperes at 120 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 notapproach the extrema of the speci-
fied range, and one that does not change rapidly. Make
sure to allow for free air flow around the heasink 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.

Alignment
The VXR-7000 is carefully aligned at the factory for the
specified performance across the entire operating fre-
quency range. Realignment should therefore not be nec
essary except in the event of a component failure. All
component replacement and service should be per-
formed only by an authorized Yaesu/ Vertex represen-
tative, or the warranty policy may be void.
The following procedures cover the sometimes critical
and tedious adjustments ttmt are not normally required
once the repeater has left the factory. However, if dam—
age occurs and some parts subsequently are placed, re-
alignment may be required. If a sudden problem occurs
during normal operation, it is likely due to component
failure; realignment should not be done until after the
faulty component has been replaced.
We recommend that servicing be performed only by
authorized Yaesu / Vertex service technicians who are ex-
perienced with the circuitry and fully equipped for re
pair and alignment. Therefore, if a fault is suspected,
contact the dealer from whom the repeater was pur-
chased for instructions regarding repair. Authorized
Yaesu/ Vertex service technicians realign all circuits and
make complete performance checks to ensure compli-
ance with factory specifications after replacing any faulty
components.
Those who do undertake any of the following alignments
are cautioned to proceed at their own risk. Problems
caused by unauthorized attempts at realignment are not
covered by the warranty policy. Also, Yaesu/ Vertex re—
serves the right to change circuits and alignment proce—
dures in the interest of improved performance, without
notifying owners.
Under no circumstances should any alignment be at-
tempted unless the normal function and operation of
the repeater are clearly understood, the cause of the
malfunction has been clearly pinpointed and any faulty
components replaced, and realignment determined to
be absolutely necessary
The following test equipment (and thorough familiar—
ity with its correct use) is necessary for complete realign—
merit. Correction of problems caused by misalignment
resulting from use of improper test equipment is not
covered under the warranty policy, While most steps
do not require all of the equipment listed, the interac—
tions of some adjustments may require that more com—
plex adlustments be performed afterwards.
Do not attempt to perform only a single step unless it is
clearly isolated electrically from all other steps. Have
all test equipment ready before beginning, and follow
all of the steps in a section in the order presented.

Alignment Preparation & Precautions
A 50 Q RF Dummy Load and in-line wattmeter must be
connected to the TX antenna jack in all procedures that
call for transmission, except where specified otherwise.
Correct alignment is not possible with an antenna,
After completing one step, read the following step to
determine whether the same test equipment will be re-
quired. if not, remove the best equipment (except dummy
load and wattmeter, in connected) before proceeding.
Correct alignment requires that the ambient tempera-
ture be the same as that of the repeater and test equip—
ment, and that this temperature be held constant be—
tween 20 “C and 30 °C (68 ”F ~ 86 °F). When the re
peater is brought into the shop from hot or cold air, it
should be allowed time to come to room temperature
before aligrunent.
Whenever possible, alignments should be made with
oscillator shields and circuit boards firmly affixed in
place. Also, the test equipment must be thoroughly
warmed up before beginning.
Note: Signal levels in dB referred to in the alignment
procedure are based on MB" = 0.5uV
Alignment
Set up the test equipment as shown below, and apply
AC power to the repeater.
The repeater must be programmed for use in the in-
tended syshein before alignment is attempted. The fre—
quency and other parameters are loaded from the file
during the alignment process.
In order to facilitate alignment over the complete switch-
ing range of the equipment it is recommended that the
channel data first be uploaded and then stored to disk.
Channels at the upper, lower and middle band edges
should then be downloaded, The original data can be
replaced at the end of the alignment process.
