General NMEA 2000 Data Type Requirements
General NMEA 2000 Data Type Requirements
Each NMEA 2000-certified sensor provides unique information to the NMEA 2000-certified display devices (such as a GPSMAP 4000/5000
series chartplotter or a GMI 10) 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. For more about PGN
