raymarine networking options

Dave,

As you have indicated, the a/c/e/eS/gS-Series MFD must be interfaced to Fusion's BB100 via NMEA 2000 communications. Ethernet communications between Raymarine a/c/e/eS/gS-Series MFDs and Fusion audio products is only supported in conjunction with Fusions 7xx Series Stereo head units. SeaTalkng is an extension of the NMEA 2000 protocol and NMEA 2000 backbones may be constructed from CAN networking components produced by Raymarine, Fusion, Maretron, Lowrance, and others. As indicated within the FAQ referenced within my initial response, the a/c/e/eS/gS-Series MFD should be updated with the latest software (v19.03 at the time of this response) when interfacing with compatible Fusion and Rockford Fosgate audio systems having a NMEA 2000 communications interface. It is further recommended that the NMEA 2000 backbone be powered by a single 12VDC power insertion located at the approximate midpoint of the backbone's LEN load ... rather than being powered by the audio product. As indicated within the previously referenced FAQ, the Fusion offers the CAB000863 unpowered spur cable which is designed to not pass power to the NMEA 2000 backbone. It is recommended that you verify that the Fusion audio components have been updated with the latest software. Finally, it is imperative you ensure that the NMEA 2000 backbone features two (no more, no less) 120 ohm resistor plugs (known as termination plugs) and that one plug has been installed within the backbone sockets forming both ends of the backbone.

Should you have addressed the items specified within this response, then it may be possible that the MFD has suffered a failure of its SeaTalkng/NMEA 2000 communications circuitry and it would be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
