  1. Autopilot controller (e.g. p70Rs).

  2. EV-1 sensor.

  3. Wind transducer (only required for Sailing vessels).

  4. iTC-5 converter.

  5. Speed data source:

    1. Speed transducer (providing STW data), or

    2. GNSS (GPS) Receiver (providing SOG data).

  6. 12 V / 24 V dc power supply (providing power to the ACU and SeaTalk NG backbone).

  7. ACU-200 / ACU-300 / ACU-400.

  8. Drive unit (e.g. hydraulic pump).

  9. Rudder angle reference sensor / transducer (M81105) — This is essential for ACU-300 systems, and highly recommended for all other systems.
