NASA wind sensor to NMEA 2000 converter and Meteoman

[DanLXIX]

I've asked this question to NASA Marine but they've not bothered replying to my email, so hopefully someone here may know the answer.

I'm fitting new instruments and have got a NASA wind sensor with the NMEA 183 to 2000 converter so it can talk to the network I'm fitting. I'm interested in their Meteoman barometer as well, but can I connect it to the wind sensor side of this converter so the data can go to both the NMEA 2000 network and the Meteoman?

That would give you two talkers on the same input which will not work, you need to multiplex them then you can either send into the concert or you have bu5 most will have 2k output

I thought the wind sensor was the talker? Maybe I've misunderstood, but I thought the Meteoman and the converter were both listeners.

 

[Daverw]

Wind sending data and meteoman sending data, both talkers, converter the listener

I can't quite work out what you want to do, but have you thought about the Yacht Devices NMEA 2k barometer for about £100? It will plug straight into the NMEA 2k side. I bought one last week but haven't fitted it yet as like many I can't get to the boat.

Now I hadn't seen that, and it's obviously a much more sensible idea than mine, thanks

I second the Yacht Devices solution. I don't have the barometer but have some of their other devices. Excellent support and you can buy direct or through their UK agent.

Give NASA a ring - they're normally very helpful, but perhaps struggling with Covid etc. at present.

I bought mine from sve.db. German company with speedy delivery - there were none in the UK.

The converter only outputs pgn 130306 which does not have any barometer data in it so inputting nmea 0183 barometer data won't come out of the converter on the nmea 2000 side.

The Meteoman is the barometer in this instance, and it has the option for taking wind info in from a sensor.

NASA actually got back to me today (maybe they saw this ) and you can connect as I had thought so that does give me an option, however I'm now thinking that the NMEA 2000 route is probably the best option to go for.

The wind converter is a listener on its 0183 input. talkers do not apply to N2K, so that's irrelevant. A 0183 listener can only be connected to a single device,

The wind sensor is a 0183 talker, it can be connected to more than one device. In the diagram above, NASA refer to the connection as being parallel, which is incorrect as it implies that two talkers are connected to the converter. The key words are "other 0183 display", which is a listener. Making this connection is simply using the terminals on the converter as a junction block, all that's happening is the wind data, in 0183 format, is being sent to the converter and the optional display, which could be the Meteoman. So, the Meteoman will receive wind data from this connection, but it will not send any data back, because the connection is one way.

To be clear, the Meteoman does not output any data and is not an 0183 talker, so daverw posts are not quite right.

The purpose here is to get the wind data in to Meteoman. Doesn't matter if Meteoman and Wind are connected together at the converter terminals or another connector is used to split the Wind output before the converter. The Wind could be connected directly to Meteoman if the converter was not being used.

As the NASA NMEA0183 implementation is not true differential, pay attention to common device grounding.

To sum up,
Yes.

I misunderstood then, I read it as the OP wanted to send data from both onto 2k buss, it appears that he wants to send wind direction to both converter and meteoman, so wind is now the only talker

I have to confess, i made the same mistake as you Dave.

Made i small edit to post #, so it reads clearer (hopefully)
