1 INTRODUCTION

The DR76 Digital Repeater, the AR78/AR80 Analog repeaters,

and AR81/AR83 Bearing repeaters have been designed to accept

a variety of digital inputs that are sensed when first switching on

the repeater.

The repeaters accept serial data (RS422). The D-type connector

has pins allocated for power and serial data.

The serial input is configured to recognize NMEA 0183 HDT,

HDG and HDM sentence structures in priority order.

All repeaters may be delivered with an optional mounting

bracket.

The repeaters should be mounted where it is most convenient for

the user, with regard to the unit’s environmental protection,

temperature range and cable length. The unit should not be

installed in area exposed to heavy vibrations.

Avoid mounting the repeater where it is easily exposed to

sunlight, as this will shorten the lifetime of the display.
