[DG] [DG] Rudder sensor with ACU-300

[Derek - Raymarine - Moderator]

Hi Maurizio,

The ACU 300 MUST have a rudder reference unit connected, otherwise it will have no direct connection to the rudder position and autopilot control will be unavailable.

You may have read that the Rudder reference unit is not essential (but recommended) for the ACU100 or ACU200?

Our advice is to always connect the rudder reference unit to the ACU300 as a preference, the autopilot will always work better with it direct connected.

regards
Derek
