Can't find a PCI-serial port

[JasonJiang2006]

Hello:

I am using a PCI-Serial card to control a serial-port stage, I can not find the serial port with Labview8.0. Windows can find this serial port. When I use the same Labview program in my old computer which has a serial port on board, it can be recognized. Shall I change something of the 'Visa serial' communication module?

The attached file is a Labview programmed driver for a motor-stage.

Thanks,

If Windows can't find the serial port, then LabVIEW isn't going to find it, and it's irrelevant what you've coded. You should go into the Windows Device Manager to see what it tells you about the device. Does it even show up in the list of devices? Does it have a driver loaded? If it doesn't show up in Device Manager, try plugging the card into another PCI slot. Does the card show up if you plug it into another computer? Perhaps the card is bad.

Thanks, but windows can find such port, I have checked the error code, it may be related the visa engining, I download the newest version and to see if something change.

Oops. Sorry I misread your statement as "Windows can't find the serial port". My bad. Maybe I need to get my eyes checked again, or it's this damn glare from the lights that's on my screen all the time.

What is the error code that you're getting? What do you see in MAX?
