The Simrad DR76 Digital Repeater displays vessel heading in degrees, on a backlit 4-digit LCD display. A secondary LED bar graph display may be used either as a rate of turn indicator, or as a steering indicator to indicate the difference between actual and set course. LCD backlight and LED bar graph brightness are independently adjustable via digital controls, for clear visibility in all lighting conditions.
The DR76 Digital Repeater accepts serial data (RS422), and runs on 24VDC. The 15-pin D-type connector has pins allocated for power and serial data. The repeater's serial input is configured to recognize NMEA 0183 HDT, HDG and HDM sentence structures in priority order.
The repeater supports panel mounting, or mounting with an optional bracket. It should be mounted where it is most convenient for the user, with regard to the unit’s environmental protection, temperature range and cable length.
