Connecting the GHC 10 to a nMEA 2000 network
Connect the GHC 10 to the CCU through your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network
on your boat, all the parts needed to build one are supplied in the GHP 10 package. Optionally, you can connect a NMEA 2000-
compatible GPS device to your NMEA 2000 network to use waypoint and route information with the GHP 10. For more information
on NMEA 2000, visit www.garmin.com .
to connect the GHC 10 to your existing nMEA 2000 network:
1. Determine where to connect the GHC 10 to your existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from the network at an appropriate location.
If you need to extend the NMEA 2000 network backbone, connect an appropriate NMEA 2000 backbone extension cable (not
included) to the side of the T-connector you disconnected.
3. Add the included T-connector for the GHC 10 to the NMEA 2000 backbone by connecting it to the side of the disconnected
T-connector.
4. Route the included drop cable to the bottom of the T-connector you added to your NMEA 2000 network.
If the included drop cable is not long enough, you can use a drop cable up to 20 ft. (6 m) long (not included).
5. Connect the drop cable to the T-connector you added in step 3, and to the GHC 10.
6.
Do not power the nMEA 2000 network on until all of the GHP 10 components are installed correctly. (See page 33 .)
Notice
If you have an existing NMEA 2000 network on your boat, it should already be connected to power. Do not connect the included
NMEA 2000 power cable to an existing NMEA 2000 network, because only one power source should be connected to a NMEA 2000
network.
