Principle of operation

The Repeater Compass receives the heading information from the gyro compass or from
the magnetic compass by means of serial heading transmission with absolute and clear va-
lues. The serial transmission is realized via the RS 422 HEADING SERIAL* interface.
If it is intended to indicate data via an NMEA RS 422 or RS 232 interface, the Repeater
Compass recognizes this type of interface and changes automatically over to gyro / magne-
tic compass operation. Selecting the telegram type via a configuration is not necessary.
The serial course information is converted into steps on the steering repeater PCB for the
stepping motor in the ration of 1 : 36 and is shown by the 360° and the 10° card.
