Marine Data MD71TMC Transmitting Magnetic Compass System – Advanced

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.

Features

• 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

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

Parts Included in this TMC System

• MD52A/B – Compass sensor
• MD97CSP – Compass sensor processor
• MD71THD – Control and Display unit; provides 2x digital NMEA 0183 outputs; applies Magnetic Corrections to digital NMEA outputs; displays the heading
• 10 m D-type 9-way interconnect cable (CAN Bus)
• 2.5 m D-type 15-way data cable for supplying system power and carrying 2x NMEA 0183 data channel outputs

Required Option: Compass Sensor Mounting (Not Included)

• Optional Sensor Mount MD54 or MD58 – this is not included as standard because it depends on the type of host magnetic compass. Since there are many different manufacturers of magnetic compass, please let us know the type of Magnetic Compass you will be fitting to so we can determine the correct sensor mount.

Products for Expanding the TMC System
