Figure 3a. GPS 17x NMEA 0183 HVS Wired for Two-Way Communication
Exceptions:
If your NMEA 0183-compliant device has only one receiving wire (Rx), connect it to the gray wire (Tx/A) from the
GPS 17x antenna, and leave the white/red wire (Tx/B) from the antenna unconnected.
If your NMEA 0183-compliant device has only one transmitting wire (Tx), connect it to the white wire (Rx/A) from
the GPS 17x antenna, and connect the white/orange wire (Rx/B) to ground.
Note: The orange (accessory on) wire is used when wiring the GPS 17x to a Garmin chartplotter, or other NMEA
0183 device that has a defined accessory signal wire. If you are wiring the GPS 17x to a device that does not have an
accessory signal wire, the orange wire from the GPS 17x should be connected to ground.
Caution: If you are wiring the GPS 17x to a device that does not have an accessory signal wire, connect the
GPS 17x power wire to the ignition or install an in-line switch. The GPS 17x can drain the battery of the boat if it is
not switched.
