48 STEP PER DEGREE RETRANSMISSION UNIT

KW948
48 STEP PER DEGREE RETRANSMISSION UNIT
The KW948 interface converts serial heading data from
a modern gyro to a 48 step per degree signal.
Applications include refitting a ship with a new gyro, whilst
retaining the existing repeaters. Applicable gyro types are the
old C Plath and Anschutz gyros.
Typical repeaters take no more than 0.8 amps per step. The
KW948 provides high voltage to rotate the repeaters, and then
it gives a low (rms) voltage to hold position at a low current.
HEADING INPUTS
All valid NMEA 0183 heading sentences, which most modern
gyros give as standard and GPS heading sensors etc.
