Page 8: Description
Heading as part of a Gyro-Compass or Transmitting Magnetic Compass system. It receives data via a NMEA 0183 type digital transmission. The Primary function of the MD69BRX is to display Ship’s Heading from a Gyro Compass (or other source of Heading) and provide a facility for taking Celestial or Terrestrial Bearings from the ship. -
Page 9: Principle Of Operation
MD69BRX 5 PRINCIPLE OF OPERATION The Repeater accepts serial heading data from a Gyro-Compass or Transmitting Magnetic Compass in digital format using standard NMEA 0183 (IEC61162-1) True or Magnetic sentence. The input is processed by electronic circuitry contained within the Repeater enclosure. Powered from 18 V to 32 V dc derived from the ships supply, power consumption is low - typically less than 4 watts. -

Page 20: Maintenance & Fault Finding
The internal LED illumination devices may be damaged or there may be damage to the PCB or rotary dimmer switch. Return the unit to Marine Data for servicing. It should be noted that the display illumination may not be noticeable under bright ambient light conditions. Illumination is controlled independently by the integral rotary dimmer control and the Remote Dimmer input, if fitted, whichever input is adjusted will take precedence. -
