M-TYPE RETRANSMISSION UNIT   KW903-M

IN, NMEA 0183 heading
OUT, M-TYPE gyro transmission

M-type reatransmisssion unit KW903-MThe RTU accept heading from a modern gyro compass in NMEA 0183 format, and outputs high power M-Type transmission.

M-Type transmission is found on many military and ex-military craft, so the application for the RTU is when the old military gyro fails and a modern gyro has to be fitted. New gyros do not output M-Type stepper. This box allows the existing repeaters to be retained.

M-Type systems operate from their own battery supply, which has its own charger. The M-Type RTU retains the same arrangement. For your information, M-Type transmission system has only 3 essential wires compared to 4 or 5 for S-type stepper or synchro systems. There are 6 states per degree. The basic 24 volt supply may be required to power illumination in the repeaters.

The unit also has an application as a transmitting magnetic compass for it will connect to an electronic compass system as well as a gyro.
