To congure the temperature offset if the menu option is not displayed:
If the temperature data displayed on the gauge connected to the GST 10 adapter is not the same as temperature data displayed on other devices,
you can congure the temperature offset to increase or decrease the displayed temperature by a specic amount.
1. From the NMEA 2000 Devices list, select the GST 10 device.
2. Select an option:
• For most Garmin chartplotters, select Review > Generic Cong.
• For other Garmin marine devices, select Cong >Generic Conguration.
3. Enter the following command: “TEMPOFFSET=”
4. After the command, enter a positive or negative decimal number, followed by Done.
For example, TEMPOFFSET=-2.5Done indicates that the temperature readings displayed on the gauge connected to the GST 10 adapter
will be decreased by 2.5 degrees Celsius.
To congure the sensor number if the menu option is not displayed:
If multiple GST 10 adapters are assigned to the same NMEA 2000 temperature source, each adapter is assigned a unique sensor number
automatically. If the “Invalid NMEA 2000 temperature conguration” error message appears, you must assign a unique sensor number to each
adapter.
For example, if two adapters are assigned the NMEA 2000 temperature source value of Live Well and the error message appears, you must
assign each adapter a unique number.
1. From the NMEA 2000 Devices list, select one of the GST 10 devices assigned to the same temperature source.
2. Select an option:
• For most Garmin chartplotters, select Review > Generic Cong.
• For other Garmin marine devices, select Cong >Generic Conguration.
3. Enter the following command: “INSTANCE=”
4. After the command, enter a positive decimal number, followed by Done.
5. Repeat steps 1–4 for each GST 10 device assigned to the same temperature source.
For example, if two GST 10 adapters are assigned the value of Live Well, assigning INSTANCE=1 to the rst adapter and assigning
INSTANCE=2 to the second adapter prevents the error message.
Restoring Factory Default Settings
You will lose all custom conguration settings when you restore factory default settings.
1. From the NMEA 2000 Devices list, select the GST 10 device.
2. Select an option:
• For most Garmin chartplotters, select Review > Factory Defaults.
• For other Garmin marine devices, select Cong > Factory Defaults.
3. Select Yes.
