Auto Pilot Upgrade

Welcomne to the Raymarine Forum lwitty,

Q1) Is the ACU200 the correct control unit for this configuration and proper unit to power the L&S drive or is the ACU400 needed?
A1) The Type 400, S3, S3G, X30 autopilot course computers should be replaced with an ACU400.

Q2) Current AP system has a Raymarine rudder reference installed, will this work with ACU200 (same vintage as the S3 and ST6002)?
A2) Yes. The currently installed Raymarine rudder reference transducer will simply be disconnected from the Rudder terminals of the autopilot course computer and then connected to the Rudder terminal block of the ACU. Prior to disconnecting the rudder transducer's leads from the Rudder terminals of the autopilot course computer, it is recommended that one note the color of the cables leads and not the color of the Rudder terminal which each lead had been connected to. This same lead/terminal color mapping will be used when interfacing the rudder reference transducer's cable to the ACU's Rudder terminal block.
