4 DESCRIPTION
The MD69BRX is a Dual Scale Dial Type Bearing Compass Repeater, provided as a bowl-only
option for retrofit or replacement into third party gimbal rings. It is designed to display Ships
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. It has a 185 mm diameter outer dial marked in 1 degree increments with numeric values
every 10 degrees plus cardinal and inter-cardinal markers. The outer dial rotates one revolution
for 360 degrees. It also has a 95 mm diameter inner dial marked in 0.1 degree increments with
numeric values every 1 degree. The inner dial rotates one revolution for 10 degrees, i.e. 36 times
for every single revolution of the outer dial. A lubber-line is provided to allow the heading indicated
by the dial to be read accurately.
The dials are illuminated for easy reading and dimmable to allow the repeater to be viewed in any
lighting condition from full sunlight to total darkness. The illumination level is adjustable down to
zero so that night vision is not affected. Dimming can be controlled either by the rotary control
mounted on the repeater bowl or by a remote dimmer.
The MD69BRX has two indicator LEDs mounted in the outer verge-ring on either side of the
lubber-line position to show the heading type in use (True or Magnetic).
The MD69BRX Bearing Compass Repeater is normally supplied with either a Gimbal Bearing or
Gimbal Pins Retrofitting Kit. We provide a range of options to fit into third-party gimbals, see the
product dimensions section for more information.
The Repeater is counterbalanced to allow it to remain in a horizontal position whilst being read,
however flush panel mounting is also available as an option.
Constructed in a robust, waterproof, aluminium enclosure and finished in RAL7040 Window Grey
paint, the MD69BRX will complement existing marine navigation equipment.
