NMEA Data

The Ray218E/Ray55E accepts NMEA 0183 (V3.01) data from a position
determining device (GPS) to provide the Latitude and Longitude position
information. This information appears on the radio's LCD display and is also
transmitted during a DSC Distress Call. When a valid NMEA signal is detected, the
GPS satellite indicator appears solid on the LCD. When no NMEA signal is
detected, the GPS satellite indicator blinks.
When Distress Call and Position (lat/lon) information is received from other
stations, your Ray218E/Ray55E also has the capability of outputting the vessel's
position to your chartplotter display unit (C Series, E Series, etc.) over the NMEA
port so that it can be displayed on the screen. See "NMEA Output" on page 61.
