Connecting the CCu to an Existing nMEa 2000 network
1. Determine where to connect the CCU
➊
to your existing NMEA
2000 backbone

2. Disconnect one side of a NMEA 2000 T-connector from the
network.
3. If necessary, to extend the NMEA 2000 network backbone, connect
a NMEA 2000 backbone extension cable (not included) to the side
of the disconnected T-connector.
4. Add the included T-connector
➌
for the CCU to the NMEA
2000 backbone by connecting it to the side of the disconnected
T-connector or backbone extension cable.
5. Route the included drop cable
➍
to the bottom of the T-connector
added in step 4, and connect it to the T-connector.
If the included drop cable is not long enough, you can use a drop
cable up to 20 ft. (6 m) long (not included).
6. Connect the drop cable to the to the CCU.

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.

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 (
