NMEA Features

Your radio supports NMEA0183 Version 3.01, a standard for data communication between marine instruments. If you are connected to a chartplotter and the radio receives another boat’s position data (sentences) in a DSC call, the radio sends the position data to the chartplotter so you can see the location.

NMEA sentences contain different sets of data. The MHS135DSC supports the following sentences:
