VXR-9000 FM REPEATER OPERATING MANUAL DB-25 CONNECTOR PORT 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 expla

33、ined in detail as follows: Pin 1: GND Chassis ground for all logic levels and power supply return. Pin 2: +13.6 V P OWER 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 A NALOG TRANSMITTER INPUT

34、(V OICE 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 T RANSMITTER INPUT (S UB-AUDI

35、BLE BAND: 5 250 HZ) This pin is sub-audiable input. The input is high im- pedance (approx. 22 k-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 C

36、TCSS or DCS, degrading performance. Use shielded cable to connect to this pin, connecting the shield to GND. 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 betwe

37、en the repeater cause to transmit mode and this port switches to ground can be programmed by your VERTEX STANDARD dealer. Pin 6: DISC OUT A NALOG OUTPUT (W IDE-BAND: 0 3,000 HZ) Received signals with standard deviation produce 350 mVrms audio at this pin. The output impedance is 600 Ohm, and is extr

38、acted 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 A NALOG OUTPUT A DC voltage proportional to the strength of the signal currently being received (Receiver Signal Strength In- dicator)

39、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: DB-25 PIN NUMBERING 7 0 60100110120(dBm)708090 0.5 1.0 1.5 2.0 2.5 (DC V) Input Signal Level RSSI Output Voltage Pin 9: COAX. SW

40、L OGIC 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 sig- nal

41、remains open (high impedance) at all time. VXR-9000 FM REPEATER OPERATING MANUAL Pin 10, 13, 15, 16, 17, 18, 19, 21: PROGRAMMABLE I/O “1” ”8” The VXR-9000 provides eight ports (PIO) that can be programmed for vari- ous input or output signals, or for con- trol functions. Each port may be pro- gramme

42、d as to its function, its status (in- put or output), and its logic (for output ports only). 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 o

43、n 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 transmit- ter while the repeater is operating in the “Remote” mode. Avoid voltage in excess of 5 V on this pin, or in- ternal damage to the microprocessor

44、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 A NALOG OUTPUT FOR DATA COMMUNICATIONS (300 3,000 Hz) This pin is an output for low speed receiving data sig- nals, with the data being extracted after the de-empha- sis

45、 and low pass filter stages. Pin 23: RXD HIGH D IGITAL OUTPUT FOR DATA COMMUNICATIONS This pin is an output for high speed receiving data sig- nals, with the data being extracted immediately after the discriminator (prior to any de-emphasis). Pin 24: TXD LOW A NALOG INPUT FOR DATA COMMUNICATIONS (30

46、0 3,000 Hz) This pin is intended to be used as a low speed data sig- nal input to the repeater. This digital data signal is in- jected before the transmitter pre-emphasis and limiting stages, so excess signal input levels are clipped. Pin 25: TXD HIGH D IGITAL INPUT FOR THE DATA COMMUNICATIONS This

47、pin is intended to be used as a high speed digital data signal input to the repeater. This digital data signal is injected after the transmitter splatter filter stage.

48、ater 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, depend- ing on the TX/RX frequency separation, and on the loca- tions available for antenna m

49、ounting. 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 at the operating frequency. When separate receive and transmit antennas are used, high-Q narrow-band types may serve to m
