Every NMEA 2000^® certified sensor provides unique information to NMEA 2000 certified display devices on the NMEA 2000 network. The data you can view on your display device depends on the sensors you have installed and configured. Refer to the following table for a list of data types that you can view on a display device; specific NMEA 2000 PGN information required to view or calculate that data type; and the NMEA 2000 sensor that typically provides required PGN information. In some cases, more than one sensor is necessary or a specific combination of sensors may provide more precise information.
