Hi,
I am a student and working in a universitary project using LabView. At the moment I try to program an interface for the WTW Cond 730 (Serial Connection). Up to now I receive data from the device, but I've got some problems with the received data and I hope you can help me out of them.
1. The first 0 to x Data packets I receive are outdated by far (e.g. I receive data from 13:15 h at 14:30 h) using 5 sec. intervals to send the data (WTW preferences). How can I remove outdated data from the interface before receiving data?
2. I receive up to 1020 Bytes presented as a string but sometimes I receive what looks like corrupt data. Nearly all of the string looks like special characters or like hieroglyphics. What went wrong and how can I fix it?
3. There are some problems in the format between Mac OS X (my programming environment) and Windows (the resulting app). I use "string subset" to get the needed string out of all the data. But when getting the correct string under Mac OS X (e.g. 25.0 °C) I get a wrong string under Windows (e.g. 20.0° iC). Would you recommend another way to get the right string than "string subset"? Furthermore the menu contains wrong special characters if ported to another System (e.g. the german "Ausgabezählwert" becomes "Ausgabezøhlwert"). It seems like the text encoding is system specific. How can I change that (e.g. to UTF8)?
The complete data I receive when everything works fine under Mac OS X looks like that:
07.10.09 16:35
110.9 mS/cm 5.2 ¯C
Tauto
nLF
Tref25 C = 0.475 1/cm
My vi: Wtw.vi
Thanks a lot!
Best wishes from germany.
