Nmea wind data.

[Allan]

The eS has two input ports (NMEA0183), each port can only receive data from a single source. So you could have log data on port 1 and wind data on port 2. If you have an unused port you can connect directly to the wind instrument OUT port, but if both ports are in use this is not possible. If both ports are in use, you can connect a 0183 to N2K converter and feed wind data into the N2 network.

As I said in my original post, I believe the 0183 data is converted to 2000 (N2k?) As I thought the Nmea systems were buses I just assumed they would all be converted and feed into the 2000 bus and therefore into the plotter. As the plotter is at the wheel, it would probably be easier to connect the wind instrument to the 0183 to 2000 converter, if there is another input. As I don't know what type of converter was used it's probably not worth asking if it's likely to have another imput?

You did say you "thought" it was converted. It could be done two ways, each 0183 device could have a converter or they could all be connected to a multiplexer, which will "merge" all of the inputs and output it as N2K data. More likely the latter, unless they just converted particular instruments and didn't include the wind instrument. They may have even used a multiplexer that didn't have enough inputs for the wind data.

If you can see how things are connected it would greatly help in advising a way forward. It's possible there is a multiplexer with a spare input, but it begs the question "why didn't they connect it". You're probably left with three options, depending how things are currently ;

1) Connect to an unused MUX input.
2) Fit an additional converter.
3) Connect the wind NMEA OUT to a spare 0183 port on the plotter.

you are confusing peeps. The B&G system I suspect is the one called Network. So it isnt a network as such, just instruments piggy backed on to each other and although they aint supposed to be fussy about the order they are piggy backed, they in reality can be fussy. They output what is supposed to be nmea 0183 and in most cases the data will be understood by other same aged stuff. So for instance I conncted my RC70 radar to the chartplotter and network nmea out and got it to understand most of the sentences, so I could see sog, lollypops, position etc on the radar also the B&G autoplot would steer to GOTO on the chart plotter BUT the vyacht wifi, the early model, which is supposed to MUX 2000 and 0183 at various speeds on the two channel connectors wont MUX, set the Ais at 38400 one channel and 4800 or is it 9600? on the other and try and get it to MUX and it goes tits up. Either the vyacht cant cope with the extra data OR the B&G sentences are slightly off spec?

Like lots of other boats we have an electronic system that has grown over the years. All but one thing works. We have B&G network instruments talking on a Nmea 0183 bus and a, recently fitted, Raymarine eS75 plotter. I think the Nmea may be converted to 2000 before feeding the plotter. Everything except the wind information is displayed on the plotter and tablet repeater down below. I suspect there maybe a problem with the information (sentence?) coming from the instrument. Is there anyway to check/change this?
Thanks in advance.

Hello Alan,

I have a Raymarine eS127 coupled to B&G Network instruments and like you find that the wind data cannot be read by the Raymarine unit. I have discussed this with Raymarine as well as Acticense and others, and the problem is simply that the Raymarine MFD will not read the VWR sentence. It needs the wind data in MWV format and that would need a converter such as the Acticense one onto a Seatalk network. This was also confirmed by B&G who also offered a very expensive converter. At this point I gave up!
