NMEA 2000 Checklist
• For other Garmin marine devices, select Cong > Tank Number.
3. Select a tank number.
4. Select OK.
Conguring the NMEA 2000 Tank Capacity
You can indicate the capacity of the uid tank that the GFL 10 adapter is associated with.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
• For most Garmin chartplotters, select Review > N2K Tank Capacity.
• For other Garmin marine devices, select Cong > N2K Tank Capacity.
3. Select the tank capacity.
4. Select Done.
Calibrating the Fluid Level
To use the GFL 10 adapter, you must calibrate the uid level of the tank that the adapter is associated with, using a minimum of two calibration
points. The greater the number of uid calibration points, the greater the accuracy of the reading on the uid-level gauge.
1. Turn the boat ignition key to the On position (not Start).
2. From the NMEA 2000 Devices list, select the GFL 10 device.
3. Select an option:
• For most Garmin chartplotters, select Review > Level Calibration > Add Calibration Point.
• For other Garmin marine devices, select Cong > Level Calibration > Add Calibration Point.
4. Select the percentage of uid currently in the tank, based on the total tank capacity.
5. Select Done.
6. Change the level of the uid in the tank.
7. Select Add Calibration Point.
8. Select the percentage of uid currently in the tank, based on the total tank capacity.
9. Select Done.
10. Repeat steps 6 through 9 to add additional, optional uid-level calibration points.
Troubleshooting the Tank Number
If multiple GFL 10 adapters are assigned to the same NMEA 2000 uid type, each adapter is assigned a unique tank number automatically. If
the “Invalid NMEA 2000 tank conguration” error message appears, you must assign a unique tank number to each adapter.
For example, if two adapters are assigned the NMEA 2000 uid type value of Live Well and the error message appears, you must assign each
adapter a unique tank number.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
• For most Garmin chartplotters, select Review > Tank Number.
• For other Garmin marine devices, select Cong > Tank Number.
3. Select a tank number.
4. Select OK.
Troubleshooting the Gauge Type
When connected to a gauge, the GFL 10 adapter gauge type is set to by default, and the adapter automatically detects the type of
gauge it is connected to. If the uid-level reading on a connected Garmin chartplotter or marine instrument changes with the engine RPM, the
adapter may be detecting the wrong type of gauge.
The uid level changes when the boat is moving. Test the gauge-type setting when the boat is not moving.
