The unit will accept all standard gyro signals such as a stepper, synchro, and all valid NMEA 0183 rate of turn or heading sentences.

Specific ‘rate of turn’ data takes priority if both the rate of turn and heading are received. If the rate of turn is not available then the unit will calculate the rate of turn from the received heading input.

An NMEA 0183 heading and Rate of Turn data output are generated for connection to external devices.
