If the "Invalid NMEA 2000 temperature configuration" 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 the GST 10 device. 2. Select an option: • For most Garmin chartplotters, select Review > Sensor Number. • For other Garmin marine devices, select Config > Sensor Number. 3. Select a sensor number. 4. Select OK.
