rudder Feedback unit (rFb) installation & calibration
Most autopilots require a rudder feedback device which is usually attached directly
to the rudder - this complicates installation in certain applications, particularly with
sterndrive and outboard engined boats. They are often exposed to the elements
and prone to damage due to
their location.
The optional Rudder Feedback
Unit is a simple solution which
attaches directly to the drive unit
itself and is calibrated using a
simple procedure.
A range of Rudder Feedback
units are available which are
compatible with most popular
autopilot systems (Fig B47).
B10a Universal RFB Setup
If a dedicated RFB is not available for a brand of autopilot, the OC15SUK27
Universal RFB should be suitable. This module is configured to the particular
autopilot using DIP switch settings:
