2 GPSX 18x LVC & GPS 18x -5Hz WIRING AND PINOUTS The GPS 18x LVC/18x-5Hz interfaces to a serial port. The unit accepts TIA-232-F (RS-232) level inputs and transmits voltage levels from ground to the input voltage, TIA-232-F (RS-232) polarity. The GPS 18x LVC/18x-5Hz wires are terminated with a six-wire connector that is used by Garmin for testing purposes. You can remove this connector without voiding your warranty (see section 1.2 Limited Warranty). 2.1 GPS 18x LVC & GPS 18x -5Hz PINOUT GPS 18x Pin # 1 2 3 4 5 6 Color Signal Name Wire Gauge Yellow Measurement Pulse Output 28 Red Vin 26 Black Ground 28 White Transmit Data 28 Black Ground 26 Green Receive Data 28 Table 1: GPS 18x LVC & GPS 18x-5Hz Wire Pinout 2.2 GPS 18x LVC & GPS 18x -5Hz WIRING DIAGRAMS Figure 1: Computer Serial Port Interconnection 190-00879-08 GPS 18x Technical Specifications Page 8 Rev.
