DSC Message Information
The DSC (Digital Selective Calling) message information feature provides, on the
chart plotter and radar displays, the MMSI no. and position* of the ships that have
transmitted a DSC message to you. A hexagon-shaped marker marks a ship's posi-
tion. The marker is color-coded according to the type of DSC message sent, red for
distress and green for non-distress.
* Position at the time of message transmission. Position information is not updated.
This feature requires connection of a DSC capable radiotelephone that outputs the
DSC sentence in NMEA 0183 format.
