NMEA Data

The Ray218/Ray55 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 Ray218/Ray55 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 62.
