Page 8: Description
MD77HRB 4 DESCRIPTION The MD77HRB is a rotating dial Compass Heading Repeater. It is designed to display Ship’s heading as part of a Gyro-Compass or Transmitting Magnetic Compass System, receiving data via a NMEA 0183 digital transmission. The MD77HRB has a dial of 118mm diameter marked in 1 degree increments with numeric values every 10 degrees plus cardinal and inter-cardinal markers. -
Page 9: Principle Of Operation
MD77HRB 5 PRINCIPLE OF OPERATION The MD77HRB accepts serial azimuth data from a Gyro-Compass or Transmitting Magnetic Compass (TMC) in digital format using standard NMEA 0183 (IEC61162-1) True or Magnetic sentences. The input is processed by electronic circuitry contained within the Repeater enclosure, powered from 18 V to 32 V dc derived from the ship’s supply. -
Page 10: Application
MD77HRB 6 APPLICATION The MD77HRB displays True or Magnetic Heading Data transmitted from NMEA 0183 (IEC 61162-1) compatible marine equipment (Gyro-Compass, TMC, EMC, GPS Compass etc.) The following NMEA 0183 sentences (in priority order) may be used to display Heading:... -

Page 17: Normal Operation
If the type of heading available changes from True to Magnetic or from Magnetic to True, the MD77HRB will automatically adjust to display the available Heading Type. If both True and Magnetic Heading data are available, True Heading will be displayed as a higher priority. -
Page 18: Alert: Loss Of Data
True and Magnetic Indicators will be illuminated. 11.5 Under Voltage Lock-out If the voltage of the power supply to the MD77HRB falls below a preset limit of 15 V, the operation of the MD77HRB is locked-out to prevent potential inaccurate display of heading. -
