Seatalk compatibility with seatalk ng
Despite my early optimism, which caused me to delete my own thread(!) I remain slightly unsure as to whether the Raymarine convertor kit, cost about 60 quid, does anything more than join wires together neatly! If that is all, there appear to be cheaper alternatives available: http://www.blueheronmarine.com/Raymarine-A06047-Seatalk-NG-To-SeaTalk-Adapter-Cable-5374. Has anyone experience of this sort of interconnection.
For background, I am considering a Raymarine plotter, and want to link into the existing ST60 instruments and tillerpilot as painlessly as possible.

The converter works but has a couple of limitations, firstly Raymarine state that you can't connect a seatalk autopilot to it and secondly if you are using a seatalk GPS then this needs to be directly connected to a seperate st/stng converter.
I understand that if you buy one of the new c or e series plotters they come with one of these 'free of charge'.

I don't recall seeing any such beast with my e7. The bigger and more expensive models may be a different story, of course.

I was told my (C-125) came with one but having just checked the manual it is not on the parts list so I don't why this happened.
As an aside, it would be nice if they reverted to paper manuals again rather just providing a CD.

paper-based manuals
I totally agree! However, at least electronic manuals allow you to look up in detail in advance- hence my question.
My big gripe is manufacturers changing accepted specifications like this, but i guess that is the same everywhere. Eg I phone5.

It is more than just a neat junction box. I believe seatalk ng is basically nmea2000 whereas seatalk is proprietary.

Seatalk NG
Thanks, Keith

Indeed - NG is definitely NMEA2000 on non-standard connectors whereas legacy Seatalk is something proprietary - and buggy according to reports.

Setting up the autopilot on Seatalk was easy peasey. Plug in the compass, rudder reference, remote, control head, plotter connection and Seatalk just works, merrily ensuring they all talk to each other. I've never had to do a single thing to the system after initially plugging it all in.

Seatalk or ng
Can you confirm that you are talking about a mixture of Seatalk and Seatalk NG?
I currently have everything, including the autopilot, working fine with Seatalk. The GPS signal comes in via NMEA from a Garmin GPS 152, although I am unsure exactly what the connections are.
The complication I am concerned about is that, by mixing Seatalk and Seatalk NG (from a proposed new plotter, that I mess up the integration. The user manual shows a circuit diagram which takes NMEA from the plotter via a Seatalk Adapter, to the Seatalk instruments. It seems to me, that if I have to do that, there is no advantage in buying a Raymarine plotter!

Which plotter are you considering fitting?

Plotter
I am thinking about the Raymarine A50 - I can get a reasonable deal in Hamburg. Other options are the Lowrance HDS 5m or the Garmin GPSMAP 620. All at about the same price, and similar screen sizes.
In an ideal setup, I want the plotter above the hatch, feeding GPS position etc to the Autopilot and radar, and reading the AIS (NASA). This data should be duplicated at the chart table with a GPS and AIS feed to the boat's laptop (running Seapro).

Be warned - i have had no luck getting our Lowrance plotter playing nicely with our Raymarine autopilot...

I would have thought that the seatalk bus should feed directly in via the converter (that is how it works on my C125) but my experiance is that if you have a seatalk autopilot on that bus then life becomes rather difficult.
(i.e. from the manual - A SeaTalk autopilot or associated controller must not be connected to the SeaTalk - SeaTalkng converter.)

GPS TO Raymarine AUTOPILOT (Thread Drift..!)
I've just thought about this some more. I am keen not to have to buy a convertor of any sort, but the existing setup must (I am not currently on board) take NMEA from the back of the GPS to the NMEA-in on the ST4000 tillerpilot. Thereafter, the Speed, Depth and Wind instruments are all daisy chained together using the original Seatalk leads.
I assume that if I take the NMEA out from the new Plotter (of whatever sort) and replicate what is already in-place, this should work. For example, the user manual of the Raymarine 50 shows a NMEA out option.
Or am I being naive?

Well, electrically you are correct. In terms of compatibility you may be being naive depending on the makes of the various components in your solution. If it's Raymarine acoss the board, you should be OK. Unfortunately, they will not go out of their way to help you make it work with a plotter from another manufacturer.

Compatibility
No, and I can accept the logic of that. The difference in cost of the various plotter options is not great, and it would make sense to go for one brand where possible. Also, I quite like the logic of the Raymarine plotter.

We have a Raymarine autopilot which only works with standard seatalk. It also has nmea0183 input and output. If it can't see the data it wants on the seatalk connection i.e position and waypoint then it looks for data on the nmea input. It bridges any data from the nmea onto the seatalk. Therefore, any plotter will work when connected and it will pass nmea data onto any daisy chained seatalk devices.

I quite like the Raymarine gear too. The thing that pushed us towards Lowrance/Simrad/B&G was the availability of broadband radar - raymarine don't have a broadband solution yet.
