Raymarine rudder angle sensor

The Raymarine Rotary Rudder Reference Transducer is compatible with S1/S2/S3, SPX, EV autopilots, ST60+ series instruments, and the iTC-5 converter. Although newer EV and older SPX series autopilots will function without a rudder angle sensor, the rudder angle sensor further improves the unit's already smooth operation. For best results, install the sensor parallel to the tiller. This way, the sensor will turn as much as the tiller, and the sensor's reading will be the most accurate. When installing, ensure that the physical zero position of the rudder and the sensor's zero position coincide. Minor deviations can be corrected later via software. After initially turning on the autopilot, check if the rudder angle sensor reading on the autopilot's screen moves in the correct direction. If it moves in the wrong direction, swap the green and red wires of the sensor cable at the ACU Rudder port.
