Where:
•
$RLS

Note: Although NMEA0183R and NMEA0183P share the same syntax, they produce different
values for AAA.AA and BBB.BB for a given layout of responders and are therefore not
interchangeable. The message type selected on the RadaScan Dashboard must always match
the message type selected on the vessel’s DP system.
