Raymarine forum

The system we are retro-fitting on a 30m long vessel includes EV-1 heading sensor, ACU 300 and P70Rs controller. A rudder reference unit was also provided with the purchase , however there is a rudder reference already fitted to the boat that supplies a signal to different driving positions (wheelhouse and fly-bridge). This rudder feedback has a 1000ohm range compared to the 5000ohm range of the Raymarine product. Is the ACU smart enough to handle the different reference signal to prevent me having to run 30m of signal cable from the steering flat to the wheelhouse? I don’t want to lose the signal to the installed rudder angle indicators otherwise I’d use the original cable and install the new rudder reference. Cam.

Hi Cam,

Thank you for your enquiry,

I am afraid that the correct format of resistance for the feedback unit is required by the ACU, the Analogue input of the correct value is essential and the ACU cannot identify alternative resistance values. A second cable will need to be run to the ACU to provide the correct feedback.

Hi Derek,

Looks like some time in the bilge for me then! Thanks for the information.
