The Simrad RF300 Go to product viewer dialog for this item. is a high-precision rudder feedback unit designed to ensure smooth, accurate auto-steering for boats with inboard engines. It operates by measuring the rudder's angle and transmitting a variable frequency signal directly to an autopilot computer. Key Features
Variable Frequency Output: Provides a frequency-based signal for direct, reliable communication with Simrad autopilot computers.
High Precision: Contributes to accurate steering by determining the exact rudder angle, which is essential for stable course-keeping.
Wide Compatibility: Designed for use in inboard engine autopilot systems and compatible with various Simrad junction units (e.g., J3XX, J50).
Robust Build: Features an IPX6 waterproof rating and an operating temperature range of -10∘Cnegative 10 raised to the composed with power C +55∘Cpositive 55 raised to the composed with power C 14∘F14 raised to the composed with power F 131∘F131 raised to the composed with power F
Flexible Mounting: Supports horizontal, vertical, or upside-down installation.
Standard Cabling: Includes a 10-meter (33-foot) twisted pair cable for flexible installation in the engine room or lazarette. Technical Specifications Dimensions ( ) Weight Supply Voltage Power Consumption Compass Safe Distance Installation Overview
To ensure proper operation and avoid rudder feedback alarms, follow these critical steps during installation: Alignment: Rotate the
transmitter lever until it aligns with the center position mark, located opposite the cable entry. Mechanical Setup: The center of the must be in line with the center of the rudder post. Transmission Arm: Ensure the Y1cap Y sub 1 dimension (rudder tiller arm) is equal to the Y2cap Y sub 2 dimension (RF300 lever) to maintain linear feedback.
Height Adjustment: Use blocking material if necessary to keep the transmission arm level.
Factory Adjustment: Do not remove the transmitter arm from the unit; it is factory adjusted and only requires external rod positioning.

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

Core Installation Requirements The Simrad RF300 Go to product viewer dialog for this item
Mechanical Connection: The unit must be mechanically linked to the rudder tiller arm or quadrant. It is critical that the center of the
is aligned with the center of the rudder post for accurate measurement.
Factory Calibration: Do not attempt to remove the transmitter arm from the feedback unit; it is factory-adjusted and only requires external setup as described in the Instruction Manual. Mounting Orientation: The
can be mounted horizontally, vertically, or upside-down, provided it is on a stable platform. Installation Steps
Alignment: Set the rudder tiller arm to the approximate center position. Rotate the
transmitter lever until its alignment mark is opposite the cable entry into the unit.
Mechanical Linkage: Drill and tap the rudder tiller arm (typically using a 4.2 mm drill and 5 mm tap). Attach the ball joint to the tiller and connect the transmitter rod between the tiller and the
Final Positioning: Secure the unit with provided screws. If necessary, use blocking material under the unit to ensure the transmitter lever is level with the rudder tiller arm.
Wiring: The unit typically uses a two-wire frequency interface for direct connection to autopilot computers. Refer to your specific autopilot computer manual (e.g., Robertson Junction Units) for correct terminal assignments, often terminals 11 and 12.
