Convert SeaTalk NG device to nmea2000

[Fuss]

Has anyone cut the end off a SeaTalk NG device and used a field connector to convert it to Nmea2000, or better might be ..made an adapter cable male SeaTalk on one end and nmea2000 on the other?
Or did you run two backbones SeaTalk and nmea2000 connected…I think Raymarine makes a cable for this.

Raymarine has all kinds of converters. And you can buy them from multiple sources including Amazon

Yes, but they don’t have a converter from a SeaTalk NG device straight to nmea2000

Ok yes that is true. I believe there are third party converters that you can buy.

If you have only one or two Seatalk NG devices and the network is all NMEA2000 then I would prefer the field connectors to reduce insertion loss from the converters.

Yes they do. And you can get them with either devicenet Male or female connectors on the other end

Raymarine part# A80675 & A80674

nice article here: https://panbo.com/finally-raymarine-...bone-adapters/

These are backbone to backbone adapters (the blue part) , not individual device adapters, so for example, you couldn’t take your SeaTalk wind instrument and use one of these cables to connect to your nmea2000 backbone.

Thanks for this answer, I think this is the way I’m going to do it.

good point you want to use the little plugin adapters for this A06083 and A06082. Not sure how robust they are.

maybe one of these would work for you.

Actually all of the latest generation of MFDs and instruments are NMEA 2000 and are delivered with adapter cable to connect them to the Seatalkng backbone. I know this because I just helped a friend install his new chart plotter and autopilot on a Seatalkng backbone and we had to use those adapter cables. It worked fine. People should realize that SeatalkNG is NMEA 2000 only with proprietary connectors to allow backwards compatibility with the older Seatalk networks. The voltages and protocols are NMEA 2000. The adapter cable from NMEA 2000 to SeatalkNG are simple cables with a SeatalkNG connector on one end and an NMEA 2000 connector on the other, with no connection to the SeatalkNG pin that provides backwards compatibility with Seatalk. There are no active components in these cables at all. They will be as dependable as any other wire in the system.

I'm confused by your subsequent remarks about the blue connectors, but I've used the A06083 to connect an i70 to a NMEA2000 network.

I will probably end up cutting up some of the Raymarine Seatalk-NG cables and fitting an NMEA 2000 plug to the other end by the time I've finished my installation though.

Do you know if it is Ray plan to eventually convert everything. Right now it is this weird mix. Interested in i70 instrument display but they are ST-NG only. Yeah I could use an adapter just annoying.

ME too. Hudson Marine sold me a ST-NG to NMEA2000 for the RM chart plotter, works perfectly.
