Simrad Rf300 Installation Manual [patched] · Reliable & Free

Ensure there is adequate clearance for future maintenance and wiring inspection. Geometry Rules

Note: If your specific cable includes an uninsulated shield/drain wire, connect it to the chassis ground terminal on the autopilot computer to prevent RF interference. Cable Routing Guidelines

Once bolted in and wired up, you must test the linkage before trusting the autopilot.

This paper provides a comprehensive technical guide for the installation, configuration, and maintenance of the Simrad RF300 Rudder Feedback Unit. As a critical component in modern autopilot systems, the RF300 provides essential data regarding rudder position, enabling accurate course-keeping and maneuverability. This document outlines the necessary tools, mounting procedures, electrical interfacing, and calibration steps required to ensure optimal performance. Special attention is given to mechanical alignment and compatibility with Simrad autopilot computers. simrad rf300 installation manual

Position the tiller arm to its central position (rudder straight ahead). Rotate the

What (hydraulic or mechanical) does your boat use?

: Attach the ball joint to the rudder tiller arm. Connect the transmitter rod to this ball joint.

The Simrad RF300 is a robust and precise sensor that dramatically improves the performance of your autopilot system. By carefully planning the mechanical installation, securing solid electrical connections, and following the proper calibration procedures, you can ensure years of smooth and accurate steering from your vessel.

Place the RF300 on its mounting surface. Align its arm so it sits at a 90-degree angle to the unit's body, representing the center position. Mark the mounting holes, drill pilot holes, apply marine sealant to the screws, and fasten the RF300 base down securely. Step 4: Assemble and Attach the Link Arm Thread the ball joints onto both ends of the linkage rod.

: If the screen shows port when the rudder moves starboard, reverse the polarity settings in the autopilot software configuration menu, or check your linkage geometry.

isn't always a "plug-and-play" affair, especially on older vessels. Here are some of the most interesting takeaways from community discussions and expert guides: If you are looking for the formal technical

The attached 10-meter cable contains two active wires. The polarity is critical for proper operation: Wire Color Signal Function Autopilot Computer Terminal Positive (+) Signal / Supply Rudder Feedback Plus ( FB + ) / FREQ White Negative (-) Return / Ground Rudder Feedback Minus ( FB - ) / GND

to the feedback lever ball joint (Y2) to ensure a 1:1 mechanical ratio.

Route the 10-meter cable from the lazarette to your autopilot processor location. Avoid running it alongside high-current cables, such as VHF antenna lines, radar cables, or engine starter wiring, to minimize electrical interference. Strip back the outer insulation of the cable cleanly.

Tighten link ball joints. Re-route the cable away from power lines. Geometry is out of square.
