Page 8: Description
Ship’s Heading as part of a Gyro-Compass or Transmitting Magnetic Compass System, receiving data via a NMEA 0183 digital transmission. The MD67HR has a dial of 118 mm diameter marked in 1 degree increments with numeric values every 10 degrees plus cardinal and inter-cardinal markers. The dial rotates one revolution for 360 degrees. -
Page 9: Principle Of Operation
MD67HR 5 PRINCIPLE OF OPERATION The MD67HR accepts serial azimuth data from a Gyro-Compass or Transmitting Heading System (THS) 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
MD67HR 6 APPLICATION The MD67HR 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 12: Installation
Connect the MD67HR in accordance with table 9.3 – Cable Core Connections (by function). The MD67HR is designed to use 24 V dc and accept a digital RS422 data signal using the NMEA 0183 protocol. Ensure all incoming supply and signal cables are suitably insulated and/or connected, or bonded to the vessel’s earth where appropriate. -

Page 14: Commissioning The System
Ensure that the installation complies with section 9 - Installation. Apply system power (24 V dc) to the MD67HR. The MD67HR Dial Compass Repeater will initially align to 000° degrees; it will then adopt the heading which is being transmitted from the heading source. -
Page 15: Operation
MD67HR 11 OPERATION The MD67HR main function is as a Heading Repeater. 11.1 Operator Controls A. Back-lit Dial, 000° - 359° B. Lubber Line C. Rotary Dimmer Control Knob and Self-Test Button D. True Heading indicator (Blue) E. Magnetic Heading Indicator (Yellow) -
Page 16: Normal Operation
If the type of heading available changes from True to Magnetic or from Magnetic to True, the MD67HR 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 17: 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 MD67HR falls below a preset limit of 15 V dc, the operation of the MD67HR is locked-out to prevent potential inaccurate display of heading. -
Page 18: Maintenance And Fault-Finding
The polycarbonate faceplate is user-replaceable. In order to change the faceplate, first ensure that the MD67HR is in a cool, dry atmosphere to avoid trapping moisture inside the unit. Place the MD67HR face upwards. Carefully remove the 8 hex socket screws (A) from the retaining bezel (B). -
Page 19: Fault-Finding
MD67HR. 12.3.2 MD67HR aligns to 000° but does not follow the source heading The NMEA 0183 digital signal to the repeater is either not present or the data sentence being sent is not of the correct structure. Check the source compass or the source of the heading data for the presence of a valid heading data sentence. -
