External Speaker 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 to 16 Ohms, and the level varies according to the setting of the front panel's VOL knob.

RX Antenna Jack

DSUB 25-pin Accessory Connector This BNC-type coaxial jack accepts the receiver in-

put signal, for connection to the receiving antenna, or the RX jack on the duplexer. The input imped-

ance requirement is 50 Ohms.

TX Antenna Jack This N-type coaxial jack provides the transmitter output signal, for connection to the transmitting antenna, or the TX jack on the duplexer. The out-

put impedance requirement is 50 Ohms. This DB-25F connector allows the repeater to be re-

mote-controlled by an external controller. Analog I/O signals, such as TX Audio In, Discriminator Output, RSSI, etc. are available. Moreover, the VXR-

9000 provides eight ports 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). 6 VXR-9000 FM REPEATER OPERATING MANUAL The VXR-9000 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 acces-

sory connector are explained in detail as follows:

Pin 1: GND Chassis ground for all logic levels and power supply return. 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 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-audiable tone input. The input imped-

ance 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). 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. DB-25 CONNECTOR PORT Pin 5: TX ATT This output is intended for controlling an external co-

axial switching relay. It is an open drain output which can sink approx. 1.5 A when active. The delay time which is between 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 In-

dicator) 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:

(DC V) e g a t l o V t u p t u O I S S R 2.5 2.0 1.5 1.0 0.5 0 60 70 80 90 100 110 120 (dBm) Input Signal Level Pin 9: COAX. SW

[LOGIC OUTPUT (ACTIVE LOW)]

This output is intended for controlling an external co-

axial 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 SIM-

PLEX mode. If programmed for DUPLEX, the signal remains open (high impedance) at all time. DB-25 PIN NUMBERING VXR-9000 FM REPEATER OPERATING MANUAL 7 Pin 23: RXD HIGH

[DIGITAL OUTPUT FOR DATA COMMUNICATIONS]

(Max.: 5 kHz) This pin is an output for high speed receiving data sig-

nals (typically 9600 bps), with the data being extracted immediately 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. DB-25 CONNECTOR PORT 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 pro-

grammed as to its function, its status

(input or output), and its logic (for out-

put ports only). Pin I/O Port 10 13 15 16 17 18 19 21 6 7 4 3 2 1 0 5 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 trans-

mitter while the repeater is operating in the Remote mode. Avoid voltage in excess of 5 V on this pin, or internal damage to the microprocessor on the repeater CNTL Unit may result. Pin 14, 20: GND Chassis ground for all logic levels and power supply return. Pin 22: RXD LOW

[ANALOG OUTPUT FOR DATA COMMUNICATIONS]

(300 ~ 3,000 Hz) This pin is an output for low speed receiving data sig-

nals (typically 1200 bps), with the data being extracted after the de-emphasis and low pass filter stages. 8 VXR-9000 FM REPEATER OPERATING MANUAL INSTALLATION Equipment Location The VXR-9000 must be installed in a 19-inch Mounting Rack, which will allow for free air flow around the heat sink on the rear apron at all times. In warm climates, the repeater should not be sealed in a small, closed room without air conditioning. While the operating temperature range of the VXR-9000 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. Protect the VXR-9000 (Mounting Rack) from wind and rain, and extremes in temperature or humidity that may shorten the useful life of the equipment. Try to lo-

cate the VXR-9000 (Mounting Rack) in an environment that is also comfortable for service personnel, if pos-

sible. Antenna Considerations Repeater operation requires two antennas, one for re-

ceiving 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, de-

pending on the TX/RX frequency separation, and on the locations available for antenna mounting. 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 necessary, use coaxial hardline cable to reduce losses. Repeater antennas should have an impedance of 50 at the operating frequency. When separate receive and transmit antennas are used, high-Q narrow-band types may serve to minimize interaction. NEVER TRANSMIT WITHOUT HAVING A TRANSMIT ANTENNA CONNECTED TO THE TX ANTENNA JACK OF THE REPEATER. VXR-9000 FM REPEATER OPERATING MANUAL 9 INSTALLATION Power Supply Operation of the VXR-9000 requires a power source ca-

pable of providing at least 12 Amps continuously at 13.6 Volts DC. The FP-1023 (23 A) and FP-1030A (30 A) AC Power Supplies are available from your Vertex Stan-

dard dealer to satisfy these requirements. Other well-

regulated power supplies may be used, as well, if they meet the above voltage and current specifications. Use the DC power cable supplied with your repeater for making power connections to the power supply. Connect the RED power cable lead to the POSITIVE (+) power supply terminal, and connect the BLACK power cable lead to the NEGATIVE () power supply terminal. Backup Power Supply For uninterrupted operation during power failures, a 12-volt rechargeable type battery (55-Ah or more rec-

ommended) may be connected to the BACKUP termi-

nal posts on the rear panel. While the repeater is oper-

ating from the Main Power Source a slight charging current will maintain battery charge. In the event of an unexpected interruption of the Main Power Source, the automatic power control circuit will automatically switch the repeater to the backup battery, and opera-

tion will not be interrupted. After prolonged operation from the battery, (Backup Power Source), it should be disconnected from the re-

peater and recharged separately before re-connecting, as the trickle charge is not sufficient for recharging a completely discharged battery. Never reapply the Main Power Source to the repeater with a discharged battery connected as backup, as the DC startup current can damage the repeater and bat-

tery. While operating from a backup battery, the repeater requires approximately 7 amperes at 12 Volts during transmit. Never short the Backup Power Sorce Terminals, when the Battery Charge switch (located on the PA Unit) is set to ON. a n n e t n A X T o T
