Garmin uses NMEA 2000 micro connectors on units, sensors, and T-connectors that are compatible with other NMEA 2000 micro connectors, cables, and NMEA 2000-compatible devices. Garmin sensors may be packaged with a drop cable and a T-connector. Garmin displays may also include additional NMEA 2000 components (such as a power cable).

When building a NMEA 2000 network, you must follow certain rules to make sure your NMEA 2000 network functions correctly. Be sure to understand the following concepts: • Linear backbone construction (page • Power connection and distribution (page • Proper termination (page • Cable length and device limits (page Technical Reference for Garmin NMEA 2000 Products...

Note: The in-line terminator connects to the NMEA 2000 backbone with a male connector, and to the final NMEA 2000 device with a female connector. Because of this, you can only use one in-line terminator on a NMEA 2000 network. Technical Reference for Garmin NMEA 2000 Products...
No more than 50 NMEA 2000 devices can be connected to your NMEA 2000 network. Existing NMEA 2000 Installation Considerations If your boat has an existing NMEA 2000 installation, and you would like to add Garmin NMEA 2000 equipment, there are a few things to consider: Cable type: Garmin uses NMEA 2000 micro connectors for all cables and connectors.

All data transmitted on a NMEA 2000 network are organized into groups. These groups are identified by a Parameter Group Number (PGN) that describes the type of data contained in the group. All Garmin NMEA 2000 devices use the proprietary PGN numbers 126720 and 61184.

Garmin NMEA 2000-certified sensors each have a Sensor Configuration Guide included in the package. For convenience, this section contains the configuration information for all Garmin NMEA 2000 sensor. All NMEA 2000 device configuration options are set from the NMEA 2000 configuration menu on your NMEA 2000 display device.
Using Fuel-Flow Information With a Garmin Chartplotter or Marine Instrument CautioN: The Garmin chartplotter or marine instrument must be powered on to calculate remaining fuel based on the fuel-flow rate. important: When using the GFS 10 to calculate remaining fuel based on the fuel-flow rate, you must specify the amount of fuel each time you add fuel to the tank.
Troubleshooting Fuel Gauge Type When wired to a fuel gauge, the gauge type defaults to Auto Detect. If the fuel-level reading on your Garmin chartplotter or marine instrument changes with the engine RPM, the GFS 10 could be detecting the wrong type of gauge.
When connected to a gauge, the GRA 10 adapter gauge type is set to auto Detect by default, and the adapter automatically detects the type of gauge it is connected to. If the rudder-angle reading on a connected Garmin chartplotter or marine instrument changes with the engine RPM, the adapter may be detecting the wrong type of gauge.
When connected to a gauge, the GRA 10 adapter gauge type is set to auto Detect by default, and the adapter automatically detects the type of gauge it is connected to. When you troubleshoot the gauge-type setting, if the rudder-angle reading on a connected Garmin chartplotter or marine instrument changes with the engine RPM, the adapter may be detecting the wrong type of gauge.

When connected to a gauge, the GET 10 adapter gauge type is set to auto Detect by default, and the adapter automatically detects the type of gauge it is connected to. If the engine-tilt reading on a connected Garmin chartplotter or marine instrument changes with the engine RPM, the adapter may be detecting the wrong type of gauge.
