How to enable NMEA output from C120W?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Andy,

The NMEA 0183 ports of Raymarine MFD's are always ON. It is recommended that you initially verify that MFD's NMEA (0183) Output settings have been configured to transmit all listed NMEA 0183 sentences. Typically the NMEA 0183 port which will be interfaced to anything other than an AIS receiver/transceiver will be configured to "NMEA 4800'. Typically, an AIS500 would have been interfaced to a C-Series Widescreen MFD via SeaTalkng communications protocol. Should the MFD have instead been interfaced to the MFD via NMEA 0183 communications protocol, then that port would need to be configured to "AIS 38400". Finally, the AIS Objects configuration setting within the Chart application page/pane being viewed must be configured to ON.

The following FAQs are also pertinent to testing the NMEA 0183 ports of MFDs and troubleshooting a NO AIS issue relative to this thread. Please note that the command sequences specified within these FAQs are those required for Raymarine's currently manufactured a/c/e/eS/gS-Series MFDs running the latest software available at the time of this response. For the corresponding command sequences for C-Series Widescreen MFDs, please consult the C-Series Widescreen Multifunction Displays Reference Manual:
