It connects directly to a compatible Simrad autopilot computer (like the AC70, AC85, or AD80) using a simple, non-polarized two-wire connection. It is important to note that the RF300 is a key part of a Simrad autopilot system and is ; it communicates via a dedicated frequency interface.

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.

If the rudder feedback is not working correctly, check the following:

Drill and tap the rudder tiller arm to attach the ball joint. The goal is to make the Y1 dimension (distance from rudder post center to ball joint) equal to the Y2 dimension (distance from RF300 pivot to attachment point). It is important to note that the RF300

: Mount the RF300 on a stable platform so its center is in line with the rudder post. You can mount it horizontally, vertically, or upside down as needed. Wiring & Connectivity
