Garmin Boating Equipment GFL 10 User Manual

GFL10 Installation and Configuration Instructions  
Use the Garmin® GFL 10 adapter to adapt analog information provided by a fluid-level sensor  
on your boat to your NMEA 2000® network. The GFL 10 adapter allows you to observe  
fluid-level information on compatible Garmin display devices connected to your NMEA 2000  
network. For a list of compatible Garmin chartplotters and devices, visit www.garmin.com.  
Compare the contents of this package with the packing list on the box. If any pieces are  
missing, contact your Garmin dealer immediately.

Warning: When connecting the GFL 10 adapter directly to the sensor on a fuel tank, make the  
connection to the sender on the tank before connecting the adapter to the NMEA 2000 network.  
This will reduce the risk of sparks near the fuel tank.  
notiCe: After connecting the adapter to the gauge or sensor, cover any exposed wires with heat-  
shrink tubing.  
Connecting the GFL 10 Adapter to a NMEA 2000 Network  
After you have connected the GFL 10 adapter to the analog gauge or to the sender, connect it  
to the existing NMEA 2000 network on your boat. If you do not have a NMEA 2000 network  
on your boat, you must build one. For more information on NMEA 2000 and to purchase  
additional connectors and cables, go to www.garmin.com.  
To connect the GFL 10 adapter to your existing NMEA 2000 network:  
1. Determine where to connect the GFL 10 adapter to your existing NMEA 2000 backbone.  
2. Disconnect one side of a NMEA 2000 T-connector from the backbone. To extend the  
NMEA 2000 backbone, connect a NMEA 2000 backbone extension cable to the side of the  
disconnected T-connector.  
3. Add the included T-connector for the GFL 10 adapter to the NMEA 2000 backbone by  
connecting it to the side of the disconnected T-connector.  
4. Connect the NMEA 2000 connector on the GFL 10 adapter to the T-connector added in  
step 3.  
5. (Optional) If the GFL 10 adapter cannot connect directly to the NMEA 2000 backbone, route  
a NMEA 2000 drop cable (not included) to the bottom of the T-connector added in step 3.  
Use a drop cable with a length up to 20 ft. (6 m). Connect the drop cable to the T-connector  
and to the NMEA 2000 connector on the GFL 10 adapter.  
notiCe: If you have an existing NMEA 2000 network on your boat, it should already be  
connected to power. Do not connect an additional NMEA 2000 power cable to an existing NMEA  
2000 network, because only one power source should be connected to a NMEA 2000 network.

Configuring the GFL 10 Adapter  
notiCe: This section provides specific configuration information for the GFL 10 adapter  
using your compatible Garmin display device. To access the NMEA 2000 configuration menu  
on your display device, consult the documentation provided with your display device.  
Configuring the NMEA 2000 Fluid Type  
You can indicate the type of fluid that is in the tank with which each GFL 10 adapter is  
associated.  
1. From the NMEA 2000 Devices list, select the GFL 10 device.  
2. Select an option:  
For most Garmin chartplotters, select Review > N2K Fluid Type.  
For other Garmin marine devices, select Config > N2K Fluid Type.  
3. Select a fluid type.  
4. Select OK.  
Configuring the Tank Number  
If your boat has multiple fluid tanks, you can indicate which tank each 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 > Tank Number.  
For other Garmin marine devices, select Config > Tank Number.

4. Select OK.  
GFL 10 Installation and Configuration Instructions  
 
Configuring the NMEA 2000 Tank Capacity  
You can indicate the capacity of the fluid 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 Config > 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 fluid level of the tank that the adapter is  
associated with, using a minimum of two calibration points. The greater the number of fluid  
calibration points, the greater the accuracy of the reading on the fluid-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 Config > Level Calibration > Add Calibration  
Point.  
4. Select the percentage of fluid currently in the tank, based on the total tank capacity.  
5. Select Done.  
6. Change the level of the fluid in the tank.  
7. Select Add Calibration Point.  
8. Select the percentage of fluid currently in the tank, based on the total tank capacity.  
9. Select Done.  
10.Repeat steps 6 through 9 to add additional, optional fluid-level calibration points.  
Troubleshooting the Tank Number  
If multiple GFL 10 adapters are assigned to the same NMEA 2000 fluid type, each adapter is  
assigned a unique tank number automatically. If the “Invalid NMEA 2000 tank configuration”  
error message appears, you must assign a unique tank number to each adapter.  
For example, if two adapters are assigned the NMEA 2000 fluid 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 Config > Tank Number.  
3. Select a tank number.  
4. Select OK.  
GFL 10 Installation and Configuration Instructions  
 
Troubleshooting the Gauge Type  
When connected to a gauge, the GFL 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 fluid-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.  
note: The fuel level changes when the boat is moving. Test the gauge-type setting when the  
boat is not moving.  
To test the gauge-type setting:  
1. When the boat is not moving, put the engine in neutral.  
2. Use the throttle to increase the engine RPM. If the fluid-level reading changes with the  
engine RPM, change the gauge type.  
To change the gauge type:  
1. From the NMEA 2000 Devices list, select the GFL 10 device.  
2. Select an option:  
For most Garmin chartplotters, select Review > Gauge Type.  
For other Garmin marine devices, select Config > Gauge Type.  
3. Select an option:  
To automatically detect the gauge type, select Auto Detect.  
To indicate a one-coil gauge, select 1 Coil.  
To indicate a two-coil gauge, select 2 Coil.  
4. Perform the gauge-type setting test.  
Resetting the Fluid Level Calibration  
You can reset the fluid-level calibration of the 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 > Level Calibration.  
For other Garmin marine devices, select Config > Level Calibration.  
3. Select Reset Calibration.  
4. Select Yes.  
5. Calibrate the fluid level.
