The ship’s heading / track control systems (Autopilot $–HTD and GPS $GPVTG) determine the Automatic Operational Mode, as required by IEC 62616:2010.
By default, SELMA BNWAS is using NC / NO contacts for interfacing to the ship’s heading / track control systems.
If required and available on the ship, the related NMEA 0183 v4.0 (IEC 61162-1:2011) signals can also be used with the addition of the NMEA Signal Processing Module.
