I am looking for same/similar information.
We have a Young wind sensor and some old interface/reporting system but no known translator. I am led to believe there is a way to interface the Young to a Vantage Pro 2 console, and from there we could get the serial data to web report, etc.
If the VP2 will take the Young connection directly somehow that would be fantastic, otherwise I don't look forward to the thought of either spending a ba-zillion dollars on what is essentially an A-D converter, or building an A-D from scratch and defining a bunch of program code and calibration steps.
We can't use the usual plastic anemometers as they get trashed in a year on a coastal hilltop slammed by dry summer heat and constant wind, or frigid winter marine layer and heavier winds.
