Connecting The Ccu To An Existing Nmea 2000 Network; Building A Basic Nmea 2000 Network For The Ghc 10 And The Ccu - Garmin GHP 10 Marine Autopilot System Installation Instructions Manual

7. Connect the drop cable to the T-connector you added in step 3, and
to the GHC 10.
NOTE: In order for the autopilot to turn on, the yellow wire from
the GHC 10 data cable be connected to the yellow wire from the
CCU/ECU interconnect cable, and the black wire from the GHC 10
data cable must be connected to the same ground as the ECU
(page 12).
Connecting the CCu to an Existing nMEa 2000 network
1. Determine where to connect the CCU ➊ to your existing NMEA
2000 backbone ➋ (page 5).
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.
