While it is a two-wire system, always follow the specific wiring diagram in your autopilot computer manual to ensure the frequency signal is correctly interpreted.
Drill and tap the rudder tiller arm (typically using a 4.2 mm drill and 5 mm tap).
Once physically installed, you must configure the autopilot software to recognize the unit. Installation manual
Connect the transmitter rod to the ball joint on the tiller arm.
Install the RF300 on a stable platform near the rudder post. The center of the RF300 should ideally be in line with the center of the rudder post to ensure geometric accuracy.
Slowly turn the helm from lock to lock by hand. Verify that the rod does not bind and that there is no mechanical interference throughout the full range of motion. 2. Wiring and Connection The RF300 uses a unique two-wire frequency-based signal .
Ensure the distance from the rudder post center to the ball joint (Y1) is equal to the distance from the RF300 center to its transmitter rod connection (Y2).
Ensure you create a "drip nose" (a loop in the cable where it enters the unit) to prevent water from running down the cable and into the feedback housing or connections. 3. System Calibration & Setup
