Simrad GC80/85 Compact MK2 Gyro Compass
Activating an external heading sensor
If an external heading sensor is connected to the GC80/85 system, DIP
switch no.5 on S1 on the ICNT board has to be set to enable the external
heading sensor.
No external sensor
Active external sensor
The external heading sensor data received must be THS, HDT or HDG (with
magnetic corrections). If output is set to THS, the input from the external
sensor must be THS as well. The same goes for HDT. When powered ON,
the Gyro will automatically detect the external sensor's baud-rate.
