Confirm that the digital rudder angle indicator on the screen accurately tracks the physical movement of the rudder.

Insert the Brown and White wires into the designated rudder feedback ports on the processor block. Screw down or clamp the terminals securely. 5. Autopilot Calibration & Commissioning

Before diving into the mechanics of installation, it’s crucial to understand the role of the RF300. Unlike a simple rudder indicator, the RF300 provides continuous, linear feedback to the autopilot computer (e.g., Simrad’s NAC series or AC series). This feedback loop allows the autopilot to make micro-adjustments to steering commands, preventing the characteristic "sawtooth" pattern of an overcorrecting autopilot.

Lock the ship's steering wheel or helm pump so the rudder sits perfectly straight at 0 degrees. simrad rf300 installation manual

When the rudder is centered, the linkage rod must form a perfect 90-degree angle with both the tiller arm and the RF300 arm. 🔧 Step-by-Step Installation Step 1: Prepare the Rudder Center your boat's rudder perfectly (dead ahead).

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
