GHP 10V Installation Instructions
Building a Basic nMEa 2000 network for the GHC 10 and
the CCu
Notice
You must connect the included NMEA 2000 power cable to the boat
ignition switch, or through another in-line switch. The GHC 10 will
drain your battery if the NMEA 2000 power cable is connected to the
battery directly.
1. Connect the three T-connectors ➊ together by their sides.

2. Connect included NMEA 2000 power cable ➋ to a 12 Vdc power
source ➌ through a switch.
Connect to the ignition switch ➍ of the boat if possible, or through
an in-line switch (not included).
3. Connect the NMEA 2000 power cable to one of the T-connectors.
4. Connect one of the included NMEA 2000 drop cables ➎ to one of
the T-connectors and to the GHC 10 ➏.
5. Connect the other included NMEA 2000 drop cable to the other
T-connector and to the CCU ➐.
6. Connect the male and female terminators ➑ to each end of the
combined T-connectors.
NOTE: The GHC 10 must connect to the CCU with the yellow
CCU signal wire in the GHC 10 data cable. The black wire must
connect to CCU ground (
Connecting optional Devices to the GHP 10V
autopilot System
To use advanced features of the GHP 10V, optional NMEA
2000-compatible or NMEA 0183-compatible devices, such as a GPS
device, can be connected to the NMEA 2000 network or to the GHC 10
through NMEA 0183.
nMEa 0183 Connection Considerations
• To identify the Transfer (Tx) A(+) and B(-) wires for your NMEA
0183-compatible device, consult the installation instructions for
your device.
• When connecting NMEA 0183 devices with two transmitting and
two receiving lines, it is not necessary for the NMEA 2000 bus and
the NMEA 0183 device to connect to a common ground.
• When connecting a NMEA 0183 device with only one transmitting
(Tx) line or with only one receiving (Rx) line, the NMEA 2000
bus and the NMEA 0183 device must be connected to a common
ground.
Connecting an optional nMEa 0183-compatible Device to
the GHC 10
1. Determine the NMEA 0183 connection assignments of your NMEA
0183-compatible device.
2. Connect your NMEA 0183-compatible device to the GHC 10, based
on the table below.

runs of wire.
4. Solder and cover all bare-wire connections.
