Raymarine forum

I have an ES78 MFD and recently purchased a Fusion BB100 unit.
My hopes were that I could connect the unit directly to the MFD using the nmea cable supplied with the BB100 and an adapter cable to connect to the Ray Marine sea talk port. The ES is not detecting the Fusion unit.

Do I need to set up a back bone system for a single connection?
Any help would be appreciated.

Hello Kenneds203,

Yes: due to the design of NMEA2000 (and the CANbus network it's based on), you can never just connect two standard NMEA2000 devices together. You always need a powered, terminated backbone-and-spur layout. You can see more detail in our SeatalkNG Reference Manual.
