Ws 2500 : datas, and how to save it

Hi from France

I’ve got a Ws2500 La Crosse weather station…

few questions: i try to get an interface which can help me to receive data every 5 mn instead of 15 with the station…
Where does WD put the data it reads from the station (or the interface) ?

In which file ??

I want to record data from the station, to built archives…

Can I read them with EXCEL (2000,XP) and treat them to make other files ??

I saw some files with data inside… but IE the wind speed is written without precision (instead of 12.3 kmh, 12 is written in the file, where is the “0.3” ??)

Sorry for the bad english but if someone could help me…

Regards…
