Hi all,
I have an HP E3631A connected to my computer using an RS232 to USB adapter and controlled with a Labview VI. When the VI is started it controls the power supply nicely, but after a while (ranges from use to use, approximately 40 minutes or so) labview loses connection and no longer controls the supply. When I try to stop the VI, labview freezes. When I try to close labview, a message of "Resetting VI: ... " shows on the screen. I have used the same adapter and power supply on another computer and didn't experience this issue. I have also adjusted the USB power options to disable the "selective suspend setting". Any other thoughts on what the problem might be? Thanks in advance.
