I am not familiar with your autopilot
, but I looked up the manual. The manual says it has NMEA
input only, no NMEA
output. So unless you have a Seatalk-NMEA converter, you will not be able to pull any data out of your autopilot.
If you do have such a converter, then your problem may be with the converter. Also, are you sure you have a rudder sensor? Does rudder angle display on the control head
As always, a VDR recording can assist in diagnosis.
