[TG] dual rudder reference sensors.

[Tom - Raymarine - Moderator]

Hello shparrot,

Don't attempt to connect the same rudder reference to both ACUs: even if you only have one ACU powered at once, putting the sensor supply voltage from one into output of the other isn't a good idea. I don't know if this would damage the ACU, but I'd say it's a possibility not to be ignored. Having both ACUs powered at once would multiply the potential problems.

Simplest solution: run the primary pilot with the rudder-reference and the backup rudder-referenceless.
Best solution: two rudder references.

Yes, you can get NMEA2000 rudder position in via an ITC5 convertor, but the data rate of this is too slow to be effective for the pilot and it wouldn't be used by the pilot. The pilot needs instantaneous data about rudder position in relation to yaw rate and drive output voltage in order for it to be useful, whereas the standard NMEA2000 rudder data update rate is only 10Hz.

Regards,
Tom
