I have a PXI-8432/2 in a couple test stations. The problem I see occasionally is the assigned serial ports on the card either don't match device manager or are in conflict with another serial port! (Conflict as in multiple hardware devices have taken the same serial port # according to windows..) .
This seems to occur when DUT's that enumerate as virtual com ports are connected/disconnected to the test station.
Here is a example of the board not fully enumerating:
- Windows Device Manager shows different VCP
When this problem occurs then I usually have to play with device manager until eventually it get's sorted out. Maybe reboot a couple times.
VISA version is 18.0.
Anybody else seeing this? Any other ideas on resolution to make this card more stable?
