NMEA / USB wiring - help welcome ! SOLVED at last !

[topodom]

Yes, I even wrote an article on the matter, I attach it to this post. EDIT : added a correction in the pdf
I got this RS232 to USB adapterr from ebay.

Thanks a lot Didier for the article !

I just want to complete something : you titled your document "Connecting 'legacy' (15y +) NMEA devices to your Rpi"

Actually it's not useful only for old devices. I bought a Nasa clipper wind system on year ago. I was not able to get the NMEA sentences on my OP system with my usb rs 486/422 converter until i sent an e-mail to Nasa support. They told me that the inteface is RS 232. So i tried to connect it following your article instructions. Now it's working like a charm !

I can now get the wind speed and direction.

Next step building a pypilot auto-pilot !
