Simrad Rf300 Installation Manual -

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

Note: Always double-check your specific computer's manual, as wire colors can vary slightly depending on the production year. 4. The "Moment of Truth" Calibration

Whether you’re a seasoned sailor or a weekend cruiser, few things are more frustrating than an autopilot that can’t find its "center." If your Simrad system is acting twitchy, it’s time to talk about the unsung hero of the helm: the RF300 Feedback Unit

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

Save the calibration settings and return to the main operational screen. 3. Verification Test simrad rf300 installation manual

The RF300 is sealed, but it should be mounted in a location protected from continuous submersion or heavy bilge water.

: Connects to the designated RF feedback terminal (typically terminal 11 on older J101A/J300X junction units). White wire

Proper mechanical installation is critical for accurate steering.

Do not attempt to remove the transmitter arm from the feedback unit. The unit is factory-calibrated; removing the arm will void the calibration and likely break the internal mechanism. Adjustments are made only via the supplied linkage rod. Once bolted in and wired up, you must

Because the RF300 uses a frequency signal, polarity is generally not critical, but sticking to standard wiring color codes simplifies troubleshooting.

When the rudder is at midships, the transmission link rod must form a perfect 90-degree right angle to both the rudder tiller arm and the RF300 feedback arm.

An accurately calibrated autopilot depends entirely on precise data from your rudder feedback unit. The Simrad RF300 Rudder Feedback Unit is a robust, high-resolution sensor that transmits the exact angle of your rudder to your Simrad autopilot computer.
