Simrad RF300 Rudder Feedback Unit is a core component for autopilot systems on inboard vessels, translating rudder movement into a variable frequency signal for the steering computer. Simrad Commercial Mounting Instructions
) is equal to the distance from the feedback unit center to its lever ball joint ( ) for a 1:1 mechanical relationship. Turn the helm to center the rudder.
: Connects to the designated RF feedback terminal (typically terminal 11 on older J101A/J300X junction units). White wire simrad rf300 installation manual
Mount the RF300 near the rudder stock. It must be installed on a flat, stable surface where the transmission link can move freely without hitting the hull or other components. Alignment:
Attach the ball joints to both the rudder tiller arm and the RF300 arm. Simrad RF300 Rudder Feedback Unit is a core
(Requires optional flush mount kit – sold separately)
The Simrad RF300 is a frequency-based rudder feedback unit designed to provide high-precision rudder angle data to your autopilot computer, such as the , or older AC12/42 units. Mounting the Unit : Connects to the designated RF feedback terminal
Verify the unit's operation by turning the helm from hard-over to hard-over to ensure the linkage moves freely and the feedback value changes correctly on the display.
If your autopilot display flashes a "Rudder Feedback Failure" or "No Rudder Data" alarm, perform these checks using a digital multimeter:
