Simrad Rf300 Installation Manual !!better!! Page

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. Key Specifications Interface 2-wire frequency interface Voltage 12-16V via CAN (typical 12V) Cable Length 10 meters (33 feet) Dimensions 99 x 65 x 177 mm Waterproof Rating 1. Physical Installation & Mechanical Linkage

Once physically installed, you must configure the autopilot software to recognize the unit. Installation manual

The goal of the mechanical installation is to maintain a between the rudder movement and the feedback unit. simrad rf300 installation manual

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 .

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. The is a high-resolution rotary rudder feedback unit

Connect the transmitter rod to the ball joint on the tiller arm.

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 Verify that the rod does not bind and

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).

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:

The unit connects directly to the rudder feedback terminals on your Simrad Autopilot Computer (such as the AC12 or AC42).
