Installation Manual: Simrad Rf300

Measure the actual physical angle of the rudder if possible, or use the default max angle specified by your vessel's manufacturer (typically 35 degrees).

Once mechanics and wiring are complete, you must calibrate the sensor using your Simrad autopilot control head (e.g., AP44, AP48, or networked multi-function display). Power on the marine electronics system.

Position the tiller arm to its central position (rudder straight ahead). Rotate the

The RF300 uses a spring-loaded rod that connects to the rudder quadrant via a small ball joint. simrad rf300 installation manual

The RF300 uses a two-wire, non-polarized frequency signal. This means wire color polarity at the autopilot computer terminal strip is generally interchangeable, but standard practices should be followed for troubleshooting purposes.

: Check the wiring continuity using a multimeter. Ensure the wires are clamped down on the bare copper wire inside the autopilot terminal block, not on the plastic insulation. Routine Maintenance

If you must extend the cable, use 2-conductor shielded marine cable and heat-shrink butt connectors. Keep extensions under 30 additional meters. Interface Configuration and Calibration

is a high-resolution, ruggedized rotary sensor designed to provide precise rudder angle data to Simrad autopilot computers. It is crucial for inboard engine vessels to achieve smooth, accurate steering. As part of the installation process, this unit requires accurate mounting to the tiller arm to ensure optimal autopilot performance. Position the tiller arm to its central position

The RF300 should be mounted close to the rudder stock.

Ensure your physical rudder is pointing dead straight ahead, then press OK on the display to confirm the zero point.
