GFS 10 Fuel Sensor Installation Instructions
Step 4: Connecting the GFS 10 to Your Chartplotter
The GFS 10 transmits data to your chartplotter or Marine Instrument using either NMEA 2000 or Garmin CANet.
Connecting the GFS 10 through NMEA 2000
The GFS 10 is packaged with a NMEA 2000 T-connector. The GFS 10 has
a built-in NMEA 2000 drop cable. Use these two components to connect
the GFS 10 to your existing NMEA 2000 network. If you do not have an
existing NMEA 2000 network, you will need to install a
NMEA 2000 network on your boat. For more information on NMEA
2000, visit
.
To connect the GFS 10 to your existing NMEA 2000 network:
1. Determine an appropriate location to connect the GFS 10 to your
existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from the backbone
nearest to the location where you want to connect the GFS 10.
If you need to extend the NMEA 2000 backbone, connect an
appropriate NMEA 2000 backbone extension cable (not included) to
the T-connector you disconnected.
3. Connect the included T-connector for the GFS 10 to the NMEA 2000
backbone.
4. Route the built-in drop cable on the GFS 10 to the bottom of the
T-connector you added to your NMEA 2000 network.
If the built-in drop cable is not long enough, you can add a drop cable
extension up to 14 ft. (4 m). If more cable is needed, add an extension
to your NMEA 2000 backbone, based on the NMEA 2000 guidelines.
Connecting the GFS 10 through Garmin CANet
The GFS 10 is packaged with a Garmin CANet adapter that you can use to connect the GFS 10 to your existing Garmin CANet bus. If you
do not have an existing CANet bus, you will need to install a CANet bus on your boat with a Garmin CANet Kit (010-10742-00). For more
information on Garmin CANet, visit
.
To connect the GFS 10 to your existing CANet bus:
1. Determine the location on your CANet bus where you would like to connect the GFS 10.
2. Wire the CANet adapter to your existing CANet bus using the diagram below to make the appropriate connections.
Follow the instructions included with the CANet Kit (010-10742-00) to determine whether a terminator is needed in the location where you
install the GFS 10.
3. Route the built-in drop cable on the GFS 10 to the CANet adapter, and complete the connection.
