[CA] AIS Source

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Leslie,

Based upon the symptoms, it appears that you may have incorrectly interfaced the GX2150 to the MFD's Power/NMEA 0183/Video Input Cable. After interfacing the MFD to the GX2150 as shown below, then the MFD's Port 1 setting will need to be configured for 4800 BAUD NMEA 0183 communications (NMEA 4800) and the MFD's Port 2 setting will need to be configured for 38400 BAUD NMEA 0183 communications (AIS 38400). In this installation, GPS data and DSC position report communications between the MFD and VHF radio will occur via 4800 BAUD NMEA 0183 communications and AIS data will be transmitted to the MFD via 38400 BAUD NMEA 0183 communications.
