23GHP 10 Marine Autopilot System Installation Instructions
Connecting an Optional GPS Device to the GHP 10 Autopilot System
Connect an optional GPS device to the NMEA 2000 network to use waypoint and route information with the GHP 10. Alternatively,
you can connect a NMEA 0183-compatible GPS device to the GHC 10 to use waypoint and route information with the GHP 10.
To connect an optional NMEA 2000-compatible GPS device to your GHP 10:
1. Add an additional T-connector (not included) for the optional GPS device you want to add to the NMEA 2000 network.
2. Connect the GPS device to the T-connector by following the instructions provided with the GPS device.
To connect an optional NMEA 0183-compatible GPS device to your GHP 10:
1. Determine the NMEA 0183 wiring assignments of your NMEA 0183-compatible GPS device.
2. Use the GHC 10 power/data cable wiring diagrams to correctly wire your NMEA 0183-compatible GPS device.
3. Use 22 AWG twisted-pair wire for extended runs of wire.
4. Solder and cover all bare-wire connections.

Wiring the GHC 10 to a NMEA 0183 Device
Notes:
Consult the installation instructions for your NMEA 0183-compatible device to identify the Transfer (Tx) A(+) and B(-) wires.
If your NMEA 0183-compatible device has only one transmitting wire (Tx), connect it to the brown wire (Rx/A) from the GHC 10,
and connect the green wire (Rx/B) to ground.
The blue (Tx/A) and white (Tx/B) wires are not used when wiring the GHC 10 to a GPS device.
The yellow (CCU signal) wire must be wired to the yellow wire of the CCU/ECU interconnect cable.
