Introduction
This manual provides the technical information necessary for servicing the VXR-9000EU Rack Mount Repeater.
Servicing this equipment requires expertise in handing surface-mount chip components. Attempts by non-qualified
persons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in
some countries.
Two PCB layout diagrams are provided for each double-sided board in this transceiver. Each side of the board is
referred to by the type of the majority of components installed on that side (“Side A” or “Side B”). In most cases one
side has only chip components (surface-mount devices), and the other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
As described in the pages to follow, the advanced microprocessor design of the VXR-9000EU allows a complete
alignment of this transceiver to be performed without opening the case of the radio; all adjustments can be performed
from the personal computer, using with the Vertex Standard VPL-1 Programming Cable and CE60 Software.
While we believe the information in this manual to be correct, Vertex Standard assumes no liability for damage that
may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any
inconsistencies in the technical information would be appreciated.

DSUB 25-pin Accessory Connector
The VXR-9000EV repeater is provided with a 25-pin DB-
25F female connector for interconnections to
accessories.Use a DB-25M 25-pin male connector to con-
nect 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 re-
turn.
Pin 2: +13.6 V
[POWER SUPPLY]
This pin provides 13.6 Volts, 2.0 A, DC from the repeater
supply. There is a internal 3 A fuse to prevent damage to
the repeater.
Pin 3: TX AF IN
[ANALOG TRANSMITTER INPUT](VOICE BAND: 300 ~ 3,000 HZ)
This pin is s audio input. Input impedance is 600 Ohms.
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: 5 ~ 250 HZ)
This pin is sub-audible tone produces 10% of full system
deviation. The nominal input voltage is 77.5 mVrms. The
input impedance is@600 Ohms, and has a flat response
characteristic (repeater deviation is constant for a given
signal level over the frequency range of 5 ~ 250 Hz). In-
jecting 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.
B-1
DB-25 PIN NUMBERING
Pin 5: TX ATT
This output is intended for controlling an external coaxial
switching relay. It is an open drain output which can sink
approx. 1.5 A when active. The delay time which is be-
tween the repeater cause to transmit mode and this port
switches to ground can be programmed by your VERTEX
STANDARD dealer.
Pin 6: DISC OUT
[ANALOG OUTPUT](WIDE-BAND: 0 ~ 3,000 HZ)
Received signals with full system deviation produce 350
mVrms audio at this pin. The output impedance is 600
Ohm, 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: N.C.
No connection.
Pin 8: RSSI
[ANALOG OUTPUT]
A DC voltage proportional to the strength of the signal
currently being received (Receiver Signal Strength Indi-
cator) 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 drain output which can sink
approx. 1.5 A 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 10,13,15,16,17,18,19,21:
PROGRAMMABLE I/O “0” ~ ”7”
The VXR-9000 provides eight ports (PIO)
that can be programmed for various input
or output signals, or for control functions.
Each port may be programmed as to its
function, its status (input or output), and
its logic (for output ports only). Each port
activates while the repeater is operating
in the “Remote”mode. See Tables on the
next page for detail regarding the input and output sig-
nals.
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 indi-
cates 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 “Remote”mode.
Avoid voltage in excess of 5 V on this pin, or internal dam-
age to the microprocessor on the repeater CNTL Unit may
result.
Pin 14,20: GND
Chassis ground for all logic levels and power supply re-
turn.
Pin 22: RXD LOW
[ANALOG 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 extracted after
the de-emphasis and low pass filter stages.
Pin 23: RXD HIGH
[DIGITAL OUTPUT FOR DATA COMMUNICATIONS]
(Max.: 5 kHz)
This pin is an output for high speed receiving data signals
(typically 9600 bps), with the data being extracted imme-
diately after the discriminator (prior to any de-emphasis).
Pin 24: TXD LOW
[ANALOG INPUT FOR DATA COMMUNICATIONS]
(300 ~ 3,000 Hz)
This pin is intended to be used as a low speed data signal
input to the repeater (typically 1200 bps). This digital data
signal is injected before the transmitter pre-emphasis and
limiting stages, so excess signal input levels are clipped.
Pin 25: TXD HIGH
[DIGITAL INPUT FOR THE DATA COMMUNICATIONS]
(0 ~ 5 kHz)
This pin is intended to be used as a high speed digital
data signal input to the repeater (typically 9600 bps). This
digital data signal is injected after the transmitter splatter
filter stage.
