Mount the unit in a dry, accessible area of the tiller flat or steering compartment. While rugged, avoiding direct submersion extends the unit's lifespan.
Ensure the transmission link does not hit the rudder post or any surrounding structures.
The RF300 draws max 50 mA at 12V DC from the NMEA 2000 bus. No separate power connection is required.
Ensure the movement is completely unobstructed. Manually move the helm from hard-over to hard-over before you wire anything up to make sure nothing binds or snaps. 3. Wiring Without the Worry
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). simrad rf300 installation manual
Support the cable every 45 cm (18 inches) using insulated zip ties. 6. Autopilot Calibration and Commissioning
Maintain a minimum distance of 30 cm (12 inches) from other electrical wiring to prevent signal interference.
Q: How do I update the software on my RF300 system? A: Check the Simrad support website for software updates and follow the instructions provided to install the latest version.
Slowly turn the helm from lock to lock by hand. Verify that the rod does not bind and that there is no mechanical interference throughout the full range of motion. 2. Wiring and Connection The RF300 uses a unique two-wire frequency-based signal . Mount the unit in a dry, accessible area
attempt to remove the transmitter arm from the feedback unit, as it is factory adjusted. busse-yachtshop.de Wiring & Electrical
When the rudder is dead ahead (0 degrees), both the RF300 arm and the tiller arm must be perpendicular (at a 90-degree angle) to the transmission link. 2. Tools and Materials Required
Check brown and white wire connections at the terminal block. Mechanical loose play or RF interference.

Adjust the length of the threaded rod so that when the rudder is dead ahead, the RF300 internal alignment matches perfectly.
transmitter lever until it aligns with the center position mark, located opposite the cable entry. : 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.
Drill and tap the rudder tiller arm (4.2 mm drill and 5 mm tap) to attach the ball joint. Initial Setup:
: Turn the helm fully to starboard, verify the physical angle, and save.
