Verify that the displayed angle matches your actual physical rudder angles (typically between 35 and 45 degrees). 5. Troubleshooting and Maintenance Common Issues
uses a two-wire connection to transmit data. It operates by converting rudder position into a frequency signal where represents the center position. Electronics Forum (Circuits, Projects and Microcontrollers)
Are you encountering any specific on your display?
Follow the on-screen prompts. The system will ask you to turn the wheel hard-over to port, confirm the angle, and then repeat the process for hard-over starboard. simrad rf300 installation manual
To achieve linear and accurate measurements, the linkage system must form a perfect parallelogram when the rudder is centered.
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.

Note: Do not attempt to remove the transmitter arm from the feedback unit itself, as it is factory-adjusted. 3. Wiring the
Once mechanically mounted and wired, you must calibrate the RF300 through the autopilot control head (e.g., AP11 or AP20). This step teaches the autopilot software the exact physical limits of your steering gear. Step 1: Access Installation Mode Turn on the autopilot system. It operates by converting rudder position into a
The RF300 is sealed, but it should be mounted in a location protected from continuous submersion or heavy bilge water.
Follow these steps to physically secure the hardware to your boat. Step 1: Prepare the Mounting Surface
: Have someone turn the helm wheel from full port (left) to full starboard (right) and back while you watch the RF300 linkage. Check that the arm moves freely and the rod does not bind or hit any obstacles at any point.
