Connect to the chassis ground or drain terminal on the computer to prevent RF interference. Connection Procedure
: Standard units come with 10 meters (33 feet) of cable, which can be extended using two-conductor marine-grade wire. Connections Brown wire
Position the tiller arm to its central position (rudder straight ahead). Rotate the simrad rf300 installation manual
Position the RF300 close to the rudder stock so the transmission link can connect easily to the tiller arm.
This is where the manual becomes dense.

Once it's bolted down and wired in, you aren't done yet. You have to teach the computer what "center" looks like. Enter your Autopilot’s Installation Menu Rudder Feedback Calibration Connect to the chassis ground or drain terminal
Follow the prompts to turn the wheel hard-over to Starboard, then Port, and finally back to Center. Why bother?
Ensure the distance between the rudder stock center and the RF300 shaft center matches the length of the linkage rod. 2. Establish Electrical Midships Alignment Rotate the Position the RF300 close to the
The distance from the pivot point to the link pin must be identical on both the rudder post and the RF300 arm. 2. Mechanical Mounting Steps
