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 .
The is a high-resolution rotary rudder feedback unit designed to provide precise rudder position data for Simrad autopilot systems, specifically for vessels with inboard engines. Installing this unit correctly is vital for smooth, accurate auto-steering and to avoid common errors like rudder feedback alarms.

Physical Installation & Mechanical Linkage
The unit connects directly to the rudder feedback terminals on your Simrad Autopilot Computer (such as the AC12 or AC42). simrad rf300 installation manual
Connect the transmitter rod to the ball joint on the tiller arm.
Before securing the unit, rotate the transmitter lever until the alignment marks are perfectly centered. These marks should be opposite the cable entry point of the feedback unit. Tiller Arm Connection: Slowly turn the helm from lock to lock by hand
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.
Once physically installed, you must configure the autopilot software to recognize the unit. Installation manual Wiring and Connection The RF300 uses a unique
