features a 10-meter cable designed for direct connection to compatible Simrad autopilot computers (e.g., AC12, AC42, AP24/28 systems).
Simrad RF300 Rudder Feedback Unit: Complete Installation & Calibration Guide
Simrad RF300 Go to product viewer dialog for this item. is a high-resolution, rotary rudder feedback unit that converts mechanical rudder movement into a variable frequency digital signal for autopilot computers.
The RF300 uses a two-wire proprietary connection. Polarity matters for proper operation. Strip back the outer insulation of the 10-meter cable by 50mm, then strip 5mm of insulation off the individual conductors.

Before you even read the first step of the , physically rotate the sensor’s lever arm through its full range. It should move smoothly without any grating or sticking. The spring inside the unit should return the arm to its center position when released. If the arm feels sticky or the spring is weak, return the unit immediately—this is a common failure point that installers sometimes miss.
The RF300 must mount close to the rudder stock, mechanically linked to the rudder tiller arm or quadrant. Do not mount it to the boat's hull or bulkhead if it is not aligned with the rudder post.
The RF300 uses a spring-loaded rod that connects to the rudder quadrant via a small ball joint. features a 10-meter cable designed for direct connection
Once physically installed, you must configure the autopilot software to recognize the unit. Installation manual
Once installed, the unit must be configured through your Simrad Control Unit or Multifunction Display (MFD). B&G RF300 Rudder Feedback Unit - Simrad Commercial
: Connects to the second designated terminal (typically terminal 12).
The linkage rod must travel in a straight line between the sensor’s lever arm and the moving point on the rudder quadrant or tiller. The manual specifies that the rod should not deviate more than 5 degrees from perpendicular to the quadrant’s arc of motion. The RF300 uses a two-wire proprietary connection

Turn the helm wheel so the rudder tiller arm is in the exact center position (straight ahead).
Connect the ball joints to the rudder tiller arm and the RF300 arm.
The RF300 requires almost zero maintenance if installed correctly. However, the mechanical linkage (ball joints and rod ends) will wear over time. Every 12 months, check the linkage for rust or play. Apply a light marine-grade grease to the ball joints to prevent seizing, but ensure no grease gets into the sealed RF300 housing itself.
