Instruction manual for operating and correctly installing the RI35 Mk2 Rudder Angle Indicator
The Simrad RI35 Mk2 is a rudder angle indicator manufactured from non-corrosive aluminum with a non-reflective black finish. It operates on frequency or current signals generated by a Simrad autopilot feedback unit, such as the RF45X, RF300, or RF100 models, and can also accept NMEA 0183 rudder angle (RSA) signals. The device provides a continuous reading of the rudder position up to 45 degrees on either side of midship.
