Instruction manual Instruction Manual This manual is intended as a reference guide for operating and correctly installing the RI35 Mk2 Rudder Angle Indicator. Please take time to read the manual to get a thorough understanding of the indicator system and its relationship to a complete autopilot system.
Instruction manual 1. INTRODUCTION The RI35 Mk2 is manufactured in non-corrosive aluminum with a non-reflective black finish. It is designed to operate from frequency or current signals generated by a Robertson autopilot feedback unit. It will also accept a NMEA 0183 rudder angle (RSA) signal. The indicator is made in standard modular size (132x108 mm) to match the Robertson AP35 autopilot.

Instruction manual 3.2 Use of NMEA The NMEA port on the RI35 Mk2 is unidirectional, i.e. it is automatically configured for input (listening) or output (talking). The listener port is also non-polarized. For best performance, if the RI35 Mk2 is to be used with a non- Robertson rudder feedback outputting NMEA data (RSA), 20Hz is recommended.
Robertson RI35 Mk2 Rudder Angle Indicator 3.4 Bracket mounting • Mount two of the bracket halves to the RI35 Mk2. • Temporarily bolt together the other two halves of the bracket to the first two halves. • Hold the RI35 Mk2 in place by hand and mark the 4 holes for the fixing screws on the mounting surface.
Instruction manual 3.6 Zero adjust Prior to making a zero adjustment on the indicator, make sure the Note ! feedback unit is installed and aligned according to it’s mounting instruction. Autopilots with no rudder zero adjust With the rudder amidships, the indicator should read zero. If not, adjust the pointer to zero reading by pressing and holding the illumination key for 5 (five) seconds.
Robertson RI35 Mk2 Rudder Angle Indicator If you let go of key before conformation of reversed deflection has Note ! been given, the RI35 Mk2 will think you meant to do a zero adjust and leave the pointer at zero. Then simply repeat section 3.6. 4.
