TMC-DU Magnetic Compass Sensor Introduction
TMC-D/U magnetic compass sensor serves the purpose of communicating with the upper machine through a 485 interface half-duplex mode. The converter shifts course information into digital signals, which provides magnetic compass heading of information for the magnetic compass repeater, AIS and automatic helm and other marine equipments. It is used mainly in the nautical field, such as the ship automatic helm. It complies with IEC 61162 HDM HDT output format, with steady operation. It can give the accurate reading of magnetic compass azimuth Angle, the output baud rate support 4800 bp/s, it has a small size, light weight and low power consumption.
