MD71MFD Multi-Function Display

MD71THD DISPLAY HEAD UNIT FOR TMC AND EMC SYSTEMS

MODEL NUMBER: MD71THD

The MD71THD Display Head Unit is the Human Input Device in a MARINE DATA Transmitting Heading Device (THD) System. Used in conjunction with the MD97CSP Compass Sensor Processing Unit it utilises the latest technology to accurately process and convert Magnetic Heading signals with unparalleled accuracy to NMEA 0183 Heading Data.

Product Description

OVERVIEW

Increasingly, Maritime Authorities are accepting the use of Transmitting Heading Device (THD) Systems. Instead of using inflexible and bulky optical apparatus (reflectors, periscopes etc.) an electronic remote display may be used. MARINE DATA offers a Transmitting Magnetic Compass (TMC) or an Electromagnetic Compass (EMC) solution. For inland navigation, an Electromagnetic Compass is commonly used which negates the requirement to procure and operate an expensive Gyro compass.

The MD71THD Display Head Unit is the Human Input Device in a MARINE DATA Transmitting Heading Device (THD) System. Used in conjunction with the MD97CSP Compass Sensor Processing Unit it utilises the latest technology to accurately process and convert Magnetic Heading signals with unparalleled accuracy to NMEA 0183 Heading Data. Features include: Variation Correction; Sensor to Compass Calibration (in a TMC system) and Automatic Deviation (in an EMC system).

MARINE DATA Transmitting Magnetic Compass Systems and Electromagnetic Compass Systems are simple and intuitive to use with quick and easy installation.

Transmitting Heading Device Systems from MARINE DATA: Flexible in application, easy to install and simple to maintain.

SPECIAL FEATURES

  • Easy calibration of Magnetic Sensor Coil with host ship’s magnetic compass by turning the ship through 450°
  • 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

APPLICATIONS

  • Provides a digital NMEA heading output to drive a Compass Repeater (or other devices)
  • An elegant alternative to using an optical reflector in a ship’s magnetic compass installation
