4.4 Connecting SeaTalk or NMEA compasses

You can connect SeaTalk or NMEA compasses to the course computer, either to replace the fluxgate compass or provide supplementary compass signals.

When you connect more than one compass to the autopilot system, the course computer processes their signals in this order of priority:

1.Fluxgate compass

2.NMEA compass

3.SeaTalk compass

This means that if you want to use a NMEA compass as the primary compass, you need to disconnect the fluxgate compass.

To connect a SeaTalk or NMEA compass to the autopilot system:

•NMEA compass: connect it to one set of NMEA inputs on the course computer

•SeaTalk compass: connect it to the SeaTalk bus or the course computer SeaTalk terminals
