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.
The orange (accessory on) wire is used when wiring the GPS 17x to a Garmin chartplotter,
or other NMEA 0183 device that has a dened 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.
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.
Step 3: Update Your Chartplotter
To ensure compatibility with the GPS 17x, upgrade your Garmin chartplotter with the latest
software. For more information, visit www.garmin.com.
