MD86
HEADING COMPARATOR UNIT
 Four NMEA 0183 (IEC61162-1) Heading Inputs
 Monitors and Compares up to Four Compass Headings
 Compass Divergence Alarm
 Integrated Heading Monitor (Off-Course Alarm)
 Selectable Heading Output for Compass Repeaters
 Touchscreen LCD Display with Graphical User Interface
 Meets IMO Requirements for Comparing Dual Gyros
 Connects to the MARINE DATA™ MD94HDU Junction Box
OVERVIEW
The MD86 Heading Comparator Unit monitors and compares the headings of up to four compasses with a NMEA heading
output. Compass types include: Gyro compass, GPS Compass, Transmitting Magnetic Compass (TMC) and Electromagnetic
Compass (EMC). In addition, the MD86 has an integrated Heading Monitor (Off-Course Alarm) with easy to set user controls.
 Two or more compass headings may be compared and an alarm given if the headings diverge by more than a pre-set amount
(compass divergence alarm)
 Ship’s Heading may be monitored and an alarm given if this exceeds a pre-set bandwidth (off-course alarm)
 Any one of the input headings may be selected for onward re-transmission to the ship’s compass repeaters
The unit is configured from the front panel LCD Touchscreen using an intuitive graphical user interface. Compact and rugged,
the MD86 offers a compass monitoring solution for locations where the available space is limited and may be either bulkhead or
panel mounted. Finished in jet black to complement other marine navigation equipment.
The MD86 Heading Comparator Unit from MARINE DATA™: Flexible in application, easy to install and simple to maintain.

APPLICATIONS
 Heading Comparator - Compares the headings of two or more compasses and sounds an alarm if the error exceeds a pre-set
value and duration
 Fulfils the mandatory IMO requirement for comparing the headings of 2 gyro compasses, where fitted
 Heading Monitor - Monitors Heading of Compass selected for re-transmission and sounds an alarm if the differs from the
Set Heading by more than a pre-set limit and for a pre-set time.
