AIS 650 problem when using auto pilot

[Chuck - Raymarine - Moderator]

Viet,

Regarding the autopilot and AIS silent mode issue reported, we have received no similar reports and have been unable to duplicate the reported issue. Accordingly, it is recommended that a system diagram (a photo of a hand drawn diagram will suffice) identifying each of the system's marine electronics products, its version of software, and how these items have been interfaced to one another be attached to this thread for further analysis.

Regarding plotting of DSC position reports, the VHF radio would need to be interfaced for two-way NMEA 0183 communications with the GPM400 to support having the MFD report/plot DSC position reports. The diagnostic features (MENU->SYSTEM DIAGNOSTICS) may be used to monitor data traffic on the Port (NMEA 0183) that the Ray240 has been interfaced to. Diagnosing a problem in which the MFD is not receiving DSC position reports should begin by monitoring the MFD's Port (configure to monitor received message traffic only (RX)) for DSC and DSE NMEA 0183 sentences when a DSC position report is received from another vessel. If present within the port's buffer, then the G-Series system will display a dialog indicating receipt of the DSC position report.
