Auto Pilot Upgrade

Hello -

I am looking to upgrade my autopilot from the current S3/ST6002+ to a new Evolution AP and would to confirm that the ACU200 is the correct unit. Here are some more details:

Current RM Equipment: E125, 2 - I70s via ITC5 for wind, speed, depth and temp, S3 & ST6002+ interfaced thru ST--> STNG converter with a P70 (ST6002 on one helm, P70 on other), AIS250, RS130 and HD Color Radar connected through ST-HS switch directly to E125.

Boat - 43' Beneteau sailboat, approx 20,000 lbs

Current AP installation has a Lecomble & Schmitt2201109 12v linear drive & motor which I will keep in place during the upgrade to work with the Evolution AP. I do not have detailed documentation for this drive/motor, but what I do have shows that it should be protected with a 20A fuse.

Questions:
1) Is the ACU200 the correct control unit for this configuration and proper unit to power the L&S drive or is the ACU400 needed?
2) Current AP system has a Raymarine rudder reference installed, will this work with ACU200 (same vintage as the S3 and ST6002)?

Thank you
