B&G Vulcan 7 not showing wind

[selguy]

Hi
Fitted a B&G Vulcan 7 over the last few days, which involved fitting a N2K network, to allow the NMEA from the existing ST70 Network (output from the NMEA port on the back of the ST70 tridata repeater).

All good when we powered up yesterday; the Vulcan can see the Depth info but it is not receiving any winddata, it seems. This is a bit odd, as the repeater is showing wind, as is the main wind instrument. I would have thought all the ST70 data would be transmitted in different sentences, at one time or another, so am a bit confused.

Does anyone have experience of this? Any ideas?

Don’t take my word for it, but I seem to recall reading somewhere, of someone else in the same situation, the wind instrument acts as the terminator - in essence one correctly terminated end, and the other terminated by wind instrument?
Have been reading up about NMEA myself over the last year, to try and plan my own install.

If you go into the System menu on the Vulcan there is a way to show all the visible devices on the network. This should list the wind instrument and all the other transducers.

The ST70 will display SeaTalk 1 and Seatalk NG ( NMEA 200 ). Are you 100% sure that the wind instrument is Seatalk NG and not Seatalk 1?

Edit: Just to make the above clear... the ST70 will display Seatalk 1, but will not convert it to Seatalk NG. Therefore if your Wind instrument is Seatalk 1 it won't get converted to NMEA by the ST70.

Hello Selguy,
I have the same exact problema: Vulcan+st70.
How did you fix It? What was the problem?

Thanks for your help!

Hi Daniele

Can you describe your connections in more detail? What does the device list show on the B&G?

I'm also having an intermittent problem where the B&G stops displaying wind until I reboot the network.

Yes that is true but if the sender fails the whole network will go down. I keep a spare terminator that can be plugged in at the mast foot in case this ever happened
