User manual YAESU VXR-9000

[. . . ] When the repeater become abnormal, such as the overheating, smoke smell of burning, etc. , turn the main power switch off and disconnect the Main Power Source connector from the rear of the VXR-9000 immediately. Also disconnect any backup power source you may have connected to the rear of the VXR-9000. Ensure that the power and antenna connections are securely made, using cables with excess capacity for the power being utilized.

[. . . ] Press (or Press and hold in for one second) this key again to stop the generation of the Test Tone. Press (or Press and hold in for one second) this key while press and holding the PTT switch to transmit the Test Tone Signal, as programmed by your VERTEX STANDARD dealer. TX POWER LOW Press (or Press and hold in one second) the PF key assigned to "TX Power Low"to set the transmitter power to the "Low" level. Press (or press and hold in one second) this key again to return to "Original" power level (determined via programming by your VERTEX STANDARD dealer). The output impedance requirement is 50 Ohms. 6 VXR-9000 FM REPEATER OPERATING MANUAL DB-25 CONNECTOR PORT The VXR-9000 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 5: TX ATT This output is intended for controlling an external coaxial switching relay. 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 1: GND Chassis ground for all logic levels and power supply return. 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 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. 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 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 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: (DC V) Pin 4: TONE IN [TRANSMITTER INPUT] (SUB-AUDIBLE BAND: 5 ~ 250 HZ) This pin is sub-audiable tone input. 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). 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. RSSI Output Voltage 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 coaxial switching relay. 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. DB-25 PIN NUMBERING VXR-9000 FM REPEATER OPERATING MANUAL 7 DB-25 CONNECTOR PORT Pin 10, 13, 15, 16, 17, 18, 19, 21: Pin 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). 10 13 15 16 17 18 19 21 Pin 23: RXD HIGH I/O Port 6 7 4 3 2 1 0 5 [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 immediately after the discriminator (prior to any deemphasis). 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 preemphasis and limiting stages, so excess signal input levels are clipped. Pin 11: NSQ DET This is an open-collector, active-low output capable of sinking about 10 mA. 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. [. . . ] 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 battery. 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.
