I have a test set application written using LabWindows 2013 SP1 that sends data over a USB connection to a radar system. The application sends data using viWrite to a serial port connection on a radar system. This application worked fine on three of our old test set systems.
We recently bought new computers to develop more test sets. When I try running our program on the new systems, I'm finding that the data transmitted in the USB message send is being garbled. Random sections of the message are being overwritten with garbage.
The new systems have a different BIOS, but all the computers are running Windows 7 Ultimate or Enterprise service pack 1 (64-bit), all are Intel I7s, and all have the same LabWindows version.
Attached are lists of the software installed on one of the original systems (PLATE 3) and one of the new ones (PLATE 5). Is there anything installed that might be interfering with the USB message send? Or anything else that might cause this problem?
