The RF300 is designed for use with Simrad autopilot systems. It interfaces via a dedicated rudder feedback cable (typically Simrad part numbers 000-08955-001 or similar, depending on the length required). It is compatible with both 12V and 24V DC systems, as the autopilot computer provides the excitation voltage. The ends with a brief checklist, but a
The RF300 features a variable frequency output (3400Hz at center, 20Hz per degree) that interfaces directly with the autopilot computer. It interfaces via a dedicated rudder feedback cable
The RF300 can measure up to ±45 degrees of rotation (90 degrees total). The manual states that the sensor’s lever arm should match the rudder’s maximum angle. If your rudder moves 70 degrees total (35 each way), adjust the pickup point on the quadrant so that the RF300’s arm moves ±35 degrees. , or you will damage the internal potentiometer.
: If you receive a "Rudder Feedback Alarm," double-check that the alignment marks were correctly observed during the center-position setup.
: Ensure the distance from the center of the rudder post to the linkage point is the same as the distance from the center of the shaft to its linkage point to maintain a 1:1 movement ratio Bertram31.com 2. Wiring Connections
