[DG] [DG] Autohelm interface w RC425

[Derek - Raymarine - Moderator]

Hi John,

The interface box in the photograph was used to connect the cockpit autopilots to an NMEA source, so was mainly used on sailing boats, but work equally well on motor boats if required. The speed selector control was used to help adjust the gain of the system for faster boats.

You previously advised that you had an Autohelm 1000 - in which case, it cannot receive NMEA0183, the ST1000 - the later model also did not receive NMEA0183, only SeaTalk. The current ST1000+ receives NMEA0183 direct.

Regards
Derek
