General NMEA 2000 Data Type Requirements
General NMEA 2000 Data Type Requirements
Each NMEA 2000-certied sensor provides unique information to the NMEA 2000-certied 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 congured. Refer to the following table for a list of data types that you can view on a display device; specic 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 specic combination of sensors may provide more-precise information. For more about PGN
information, see page 18.
