1. INTRODUCTION

The RI35 Mk2 is manufactured in non-corrosive aluminum with a non­reflective black finish.

It is designed to operate from frequency or current signals generated
by a Simrad 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 Simrad AP35 autopilot.

A separate PCB is mounted inside the instrument to convert the input
signals and drive the indicator.

The instrument gives a continuous reading of the rudder position up to
45 degrees on either side of the midship’s position. With no signal input
the pointer moves out of scale to port.

A front panel key is used for illumination and setup adjustments.

The splash proof construction allows panel, bulkhead or bracket
mounting in exposed locations, such as bridge wings as well as wheel
house and engine room.

3. INSTALLATION

The RI35 Mk2 is designed for flush, bulkhead or bracket mounting, and
should be positioned in a location in clear view of the helmsman. When
the mounting location is determined, the cables should be connected to
RI35 Mk2 before the unit is mounted. Cables may be taken out
underneath, or in the back of the RI35 Mk2.
