Interfacing
With the autopilot system there are several possibilities to connect
to other equipment for data collection and exchange:
1. NMEA 2000 device directly through Micro-C connectors and cables.
2. SimNet device via adapter cable, part no. 24005729.
3. NMEA 0183 via AT10 converter (+ adapter cable).
The different connecting diagrams on the following pages illustrate
the interface possibilities of the autopilots.
