Any Raymarine experts out there?

I have an e97 and e7 connected via a back bone, I can get everything to work fine on the e97 and e7 but I cannot operate or display the radar on the e7. The radar is connected via WiFi to the e97 but I would assume as both MFDs are on the backbone, I should still be able to operate it from the e7. Any ideas?

I also have two further A67s to display engine data etc, do I drop these onto the backbone as well?

Thanks in advance.

No, I don't think it is possible for Radar data to be broadcast over a NMEA 2000 backbone because there's too much data. NMEA 2000 is a type of serial bus. I expect your Radar data must be communicated to your devices via Ethernet, physical ethernet cables or WiFi.

I believe there is an app that might help though... RayControl, Screen Mirroring seems to be the thing,

I have a Garmin and the radar goes straight to the Chart plotter. From memory there are no NMEA 2000 data sentences to carry radar data.

There aren’t, because as mentioned, the data rate is too high.

Raymarine call their ethernet connectivity Seatalk HS.

Both those MFDs should have Seatalk HS sockets and you should be able to connect them direct (although the plugs are quite chunky).

That should allow the flow of radar data between the two.

Thanks for confirming that. I was working up from first principles. Knowing the CAN bus architecture, NMEA 2000 is based on it, well that makes sense.

If the OP wants RADAR on both displays then another solution needs to be found. One for the boffins at Raymarine and Garmin.

If those boffins ever intended it to be so, they have probably provided an ethernet socket. Garmin’s is RJ45, but I wouldn't put it past Raymarine to invent their own connector.

Ha, yes, missed that. Garmin’s plugs are quite fat too, cos they’re not just RJ45, but a bleeding great waterproof seal. And it invalidates your warranty to use anything else.

I forgot to say these can be connected to the NMEA backbone. If it is Seatalk NG you need the black and white drop cables connected to the appropriate socket.

Thanks all, so my understanding is I need to link the two e series plotters together using a Raynet cable and drop everything onto the back bone as well?
