VISA Error (Hex 0xBFFF003E) Virtual Serial Port

Hello,

I am trying to communicate between an Inficon VGC502 controller and LabVIEW using a virtual serial port. The virtual serial port is established by an Ethernet cable.

I tried several ways to fix it, I updated the Firmware of the controller and the NI-VISA drivers to see if that was the problem. I know that the controller communicates by ASCII strings in the form of mnemonic operating codes and parameters. Perhaps it is just a setting that I need to adjust in LabVIEW or NI-Max?

I was wondering if anyone knows how to overcome the VISA error (Hex 0xBFFF003E) "could not perform operation because of I/O error".

Thank you,

Greg A.
