MD71TMC

Instead of using inflexible and bulky optical apparatus (reflectors, periscopes etc.) to view the magnetic compass, electronic remote displays may be used in the form of a Compass Repeater. The Marine Data MD71TMC is a Transmitting Magnetic Compass (TMC) System which detects and transmits the ship’s Compass Heading over a NMEA 0183 digital connection to one or more Compass Heading Repeaters at any convenient location on a vessel.

The Marine Data MD71TMC is a Transmitting Magnetic Compass (TMC) System which uses the latest technology to accurately process and convert the ship’s magnetic compass heading to NMEA 0183 heading data with unparalleled accuracy. TMC systems from Marine Data are simple and intuitive to use with quick and easy installation and on-board calibration.

Applications: Provides a digital NMEA heading output to drive a Heading Repeater (or other devices) at a convenient location. An elegant alternative to using an optical reflector in a ship’s magnetic compass installation

Key feature:

  • Automatic calibration of the Magnetic Sensor Coil with host ship’s magnetic compass by turning the ship through 390°
  • Intuitive menu-driven installer assistance when mounting the Sensor Coil to the ship’s host magnetic compass
  • Dual power supply inputs
  • Bright OLED display provides good clarity with high contrast and wide viewing angles
  • Output: 2x NMEA 0183 data channels
