The Simrad RF300 is a frequency-based rudder feedback unit designed to provide high-precision rudder angle data to your autopilot computer, such as the , or older AC12/42 units. Mounting the Unit

Proper mechanical installation is critical for accurate steering.

Mount the RF300 near the rudder stock. It must be installed on a flat, stable surface where the transmission link can move freely without hitting the hull or other components. Alignment:

Ensure the feedback arm and the rudder arm are parallel when the rudder is in the dead-ahead position. The transmission link should be at a 90-degree angle to both arms. Connection:

Use the supplied 10m cable to reach your autopilot computer. If you have a custom quadrant, you may need to drill and tap a small hole into the bronze rudder arm for the ball mount. Wiring & Electrical Setup

The RF300 is a two-wire frequency-based sensor (3400Hz center, 20Hz/degree). Terminals: Connect the cable to the dedicated Rudder Feedback terminals on your autopilot computer.

Frequency sensors like the RF300 are generally not polarity-sensitive, but always refer to your specific computer’s wiring diagram (e.g., AC12/42 Installation Manual ) to confirm terminal pins. Dockside Calibration

Once wired, you must "teach" the system the rudder's physical limits. Enter Installation Menu: On your control unit (like an ) or MFD, navigate to Settings > Autopilot > Installation Select Source: Ensure the rudder source is set to

. If you have no physical sensor, you would use Virtual Rudder Feedback (VRF), but for the RF300, VRF should be Rudder Calibration:

Follow the on-screen wizard to turn the wheel hard-over to port, then hard-over to starboard. This sets the maximum rudder angles and centers the steering. Quick Maintenance Tips B&G RF300 Rudder Feedback Unit | Autopilot - Simrad

SIMRAD RF300 Installation Manual Report

Introduction: The Simrad RF300 is a radar system designed for use on various vessels. The installation manual for this system provides detailed instructions for ensuring a correct and safe installation. This report summarizes the key points from the Simrad RF300 Installation Manual. Unpacking and Inspection : Upon receiving the RF300

Pre-Installation Checks:

  1. Unpacking and Inspection: Upon receiving the RF300 system, inspect all components for damage. Check the package contents against the list provided with the system.
  2. System Compatibility: Ensure the system is compatible with your vessel's electronics and power supply.
  3. Mounting Location: Choose a mounting location that provides a clear, unobstructed view of the radar's scanning area, typically at a height to minimize interference from the vessel itself.

Installation Steps:

  1. Mounting the Antenna Unit:

    • The antenna unit should be mounted on a sturdy structure that can support its weight and withstand environmental conditions.
    • The manual specifies a minimum distance from other antennas to prevent interference.
  2. Installing the Radar Processor Unit:

    • This unit can be mounted in an electronics rack or on a bulkhead, ideally in a well-ventilated area protected from moisture.
    • Connections for power, data, and optionally for interfacing with other electronics (like chartplotters) are detailed.
  3. Display Unit Installation:

    • The display unit's location should offer a good viewing angle and be within easy reach of the operator.
    • Connection to the radar processor unit and power supply is required.
  4. Power Supply Requirements:

    • Ensure the power supply matches the system's requirements as specified in the manual.
    • Proper grounding of the system is crucial for safety and performance.
  5. Interfacing with Other Equipment:

    • The manual provides details on connecting the RF300 to other onboard systems, such as chartplotters, autopilots, and NMEA devices.

Post-Installation Procedures:

  1. System Check: Turn on the system and verify that all components are functioning correctly.
  2. Adjustments and Settings: Perform initial adjustments, such as setting up antenna alignment and adjusting sensitivity for optimal performance.

Safety Precautions and Warnings:

Conclusion: The Simrad RF300 Installation Manual provides comprehensive guidelines for the proper installation of the radar system. Following these guidelines ensures not only optimal performance but also safety for the users and those on board the vessel. It's crucial for installers to be familiar with the manual and to follow each step carefully to avoid any issues or hazards.


4.3 Setting the Travel Range

The RF300 has mechanical stops to prevent the internal potentiometer from being damaged by over-rotation.

  1. Turn the wheel hard to port and hard to starboard to determine the maximum rudder travel.
  2. Adjust the length of the linkage arm and the position of the feedback unit so that the rudder hits its mechanical stops before the RF300 hits its internal stops.
  3. Warning: If the rudder stops after the RF300 reaches its limit, the internal gears or potentiometer will be stripped, rendering the unit useless.

3. What’s in the Box

Common Wiring Mistakes from the Manual’s Warnings:

  1. Using the wrong power source: The manual explicitly warns not to power the RF300 from a house battery or ignition circuit. It must receive stable, noise-filtered power from the autopilot computer’s dedicated sensor supply (typically 5V or 12V regulated).
  2. Extending the cable incorrectly: The RF300 cable is 5 meters. If you need more, the manual advises using marine-grade shielded cable (2 twisted pairs + drain). DO NOT use standard automotive wire—it will introduce electrical noise that mimics rudder movement.
  3. Ground loops: Connecting the green drain wire at both ends creates a ground loop. Follow the manual: connect the drain only at the autopilot computer’s common ground terminal.

4.4 Electrical Connections

  1. Route the rudder feedback cable from the autopilot computer location to the RF300 mounting location. Avoid routing the cable parallel to high-current AC wires to prevent interference.
  2. Connect the cable to the RF300. The standard Simrad pinout for the RF300 typically follows the color code (referencing the specific autopilot manual is essential, but standard configuration is):
    • Red: +5V DC Supply (from Autopilot)
    • Blue/Black: Signal Output
    • Green/Yellow: Ground (Shield)
  3. Secure the cable with tie-wraps to prevent strain on the connector.
