Pick-off sensor SCP-NT detects heading reference of a magnetic compass and converts it into NMEA serial data for input to other navigational equipment.
Either one of the serial sentence; HDM or HDT, can be selected by inner short pin arrangements. A built-in variable resistor allows adjustment of output by +/- 10 degrees, thus, making the HDT output to align to a True North datum when its local variation is known.
Calibration of output can be made at twelve (12) cardinal points, by correcting PC having RS232C communication port. Windows utility "Hyper-Terminal' is required.
With mounting plate supplied as standard, SCP-NT Pick-off sensor is fitted simply onto Saura magnetic compasses. Special mounting plates are also available, to suit some of the popular magnetic compass bowls from other manufacturers.
