How do I configure my chart plotter so that an incoming Mobilarm V100 DSC distress alert logs a waypoint when a man overboard event occurs?
Some DSC radios can output DSC and DSE messages via a NMEA connection. When the VHF DSC radio receives the distress alert it may be able to output a NMEA0183 sentence direct to a connected GPS or chart plotter and log a waypoint of the coordinates received in the distress alert. This will plot the casualty’s first known position and track them in the water with every subsequent updated position received. Refer to your radio owner’s manual to determine whether your DSC radio is capable of sending NMEA0183-compatible data to your GPS or chart plotter and if so, ensure that your GPS or chart plotter is correctly configured to accept this data protocol.
