(DG) Replacing a 150ASG with an ACU-200 -- wiring questions

[Derek - Raymarine - Moderator]

Hi ddfour1

Thank you for your enquiry.

To answer point by point if I may . . .

The Fluxgate compass is no longer required and so the cabling can be completely removed, the EV1 sensor connects via a spur cable and backbone of STng.

The existing rudder reference unit can be transferred directly and connected colour for colour to the new ACU200 - although the RED and GREEN wires may need to be swapped once the system is powered and commissioned - swapping the RED and GREEN will reverse the operation of the rudder angle transducer if the display goes the opposite direction to that required.

The off switch can be connected to the SLEEP connections on the ACU200

The SeaTalk wires no longer connect to the ACU 200 and so can be removed, the system operates on STng data protocol and any connection to legacy SeaTalk equipment onboard is via the STng to SeaTalk converter.

The power and drive motor wires will be transferred across to the ACU200, note that the MOTOR connections may need to be swapped about once the system is commissioned if the motor operates the reverse direction to that expected.

The ACU 200 can operate both hydraulic and Mechanical drives. If a hydraulic drive is used, no clutch connection is required.
