ST6001+ NMEA and HSB2 SeaTalk interface

Greg,

Two points:

- The autopilot's NMEA 0183 port is exclusively designed to support 4800 BAUD NMEA 0183 communications. NMEA 0183 AIS communications required 38400 BAUD NMEA 0183 communications. As such, multiplexing data from the AIS transceiver with that from the PC will result in 38400 BAUD NMEA 0183 output from the multiplexer ... this cannot then be transmitted to the autopilot's NMEA 0183 port. The 4800 BAUD NMEA 0183 output from the PC alone should be interfaced to the NMEA 0183 input port of the autopilot.

- Raymarine equipment of the vintage specified is not designed to support more than one source for any specific data item COG, SOG, heading, latitude, longitude, etc. Correspondingly, care should be exercised when interfacing a second potential source of GPS data to the system (in this case the third party AIS transceiver). When doing so, it is recommended that the AIS transceiver be configured to not transmit GPS data via it NMEA 0183 interface.
