Physical Installation & Mechanical Linkage
The goal of the mechanical installation is to maintain a 1:1 relationship between the rudder movement and the feedback unit.
Mounting Location: 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.
Alignment Marks: 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:
Drill and tap the rudder tiller arm (typically using a 4.2 mm drill and 5 mm tap).
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).
Connect the transmitter rod to the ball joint on the tiller arm.
Testing Movement: 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.
Direct Connection: The unit connects directly to the rudder feedback terminals on your Simrad Autopilot Computer (such as the AC12 or AC42).
Polarity: 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.
Drip Loop: 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
Once physically installed, you must configure the autopilot software to recognize the unit. Installation manual

The Simrad RF300 Rudder Feedback Unit is a critical component for boat autopilot systems, specifically designed for vessels with inboard engines to provide precise rudder angle data. Installation involves precise mechanical alignment and a simple two-wire electrical connection to an autopilot computer. 1. Mechanical Mounting and Alignment
Correct mechanical placement is vital to prevent rudder feedback alarms.
Location: Mount the RF300 on a suitable platform where its center is directly in line with the center of the rudder post.
Orientation: The unit can be mounted horizontally, vertically, or upside-down. Linkage Setup: Do not remove the factory-adjusted transmitter arm.
Drill and tap the rudder tiller arm (typically using a 4.2 mm drill and 5 mm tap) to ensure the linkage dimensions are equal (Y1 = Y2).
Align the transmitter lever with the alignment marks provided; it should be opposite the cable entry when the rudder is centered.
Safety Check: Move the steering from port to starboard to ensure the transmission link does not hit any components or pass "over dead center," which could block the system. 2. Electrical Wiring
The RF300 features a variable frequency output (3400Hz at center, 20Hz per degree) that interfaces directly with the autopilot computer.
Connection: Use the supplied 10-meter (33-foot) cable to connect the unit to the "Rudder Feedback" terminals on compatible computers like the NAC-3, AC70, or H5000.
Routing: Ensure the cable is clamped to allow for full rudder movement and include a "drip loop" to prevent water from following the cable into the unit. 3. Calibration and Testing
After physical installation, the system must be calibrated via the autopilot control head or multifunction display (MFD).
Dockside Setup: Access the Installation Menu and select the RF300 as the source for rudder feedback.
Rudder Calibration: Follow the on-screen instructions to set the center point and maximum travel limits for both port and starboard.
Verification: Regularly inspect the sensor cable for corrosion and verify that the rudder indicator on the display accurately matches the physical rudder position. B&G RF300 Rudder Feedback Unit | Autopilot - Simrad
