Hey C@TI
I took a look at that pdf, but wasn't really sure what you wanted to do. Could you explain to me exactly what you want to do, send, receive. If you could help me understand your VI better I can try to help make it work.
It would also be helpful if I knew what version of LabVIEW you are using, what drivers you have, and what the operating system is your PC running on.
Regards
