Em-Trak B100 AIS and C80 Plotter

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Breezotoo,

Please click here to view a FAQ addressing this subject. The AIS receiver/transceiver should not be interfaced to the NMEA 0183 terminals of the SPX autopilot course computer, as Raymarine autopilot course computers are neither designed to support 38400 BAUD NMEA 0183 communications nor are they designed to process/bridge NMEA 0183 AIS data sentences (ex. VDO, VDM, ALR, etc.) to SeaTalk (the communications bus through which the SPX autopilot and MFD should have been interfaced to one another). In this case:
- the MFD NMEA 0183 Cable's IN+ (white) lead will need to be interfaced to the Em-Trak B100 AIS transceiver's 38400 BAUD NMEA 0183 OUT+ (brown) lead.
- the MFD NMEA 0183 Cable's IN- (green) lead will need to be interfaced to the Em-Trak B100 AIS transceiver's 38400 BAUD NMEA 0183 OUT- (blue) lead.
- the MFD NMEA 0183 Cable's OUT+ (yellow) lead will need to be interfaced to the Em-Trak B100 AIS transceiver's 38400 BAUD NMEA 0183 IN+ (white) lead.
- the MFD NMEA 0183 Cable's OUT- (brown) lead will need to be interfaced to the Em-Trak B100 AIS transceiver's 38400 BAUD NMEA 0183 IN- (green) lead.
