PCI serial RS-232/485 isolated 2 port card not recognized

Solved!
Go to solution

I have a PCI serial RS-232/485 isolated 2 port card on my computer. I installed the card and then the software but my computer has never recognized that there is a card in the PCI slot.  Because this card is old I also tried to install the older versions of the serial software but it did not help.  I have a Windows 7 x32bit computer and other PCI cards were installed in the same slot  before this one so I know the slot works.  The card was built long before Windows 7 and I don't know if they are compatible.  I was wondering if there was any way to force the computer to recognize the hardware or if there is a way to check to see if the card still works.

 

Thanks

Greetings,

 

It is possible that the card is too outdated. However, I am wondering if you can see the card at all in the windows device manager. Basically I am wondering if the card does not appear at all in device manager, or if it appears as an unrecognized card.Please let me know.

 

Thanks,

James Duvall

Typically you install the software first, shut down the PC, and then install the card.

NI has never sold a PCI board with both RS-232 and RS-485 ports, so am I correct in assuming that this is not a National Instruments product? If so, you should contact the board's manufacturer to find out if a driver is available. While it is possible to force Windows to attempt to load a different driver, this typically will not work unless you know with absolute certainty that the driver you are forcing is actually compatible.

On the board itself, it says both RS-232 and RS-485 in its name. However, it has only RS-232 ports. It does not appear in the windows device manager.

 

Thanks,

How do you know that they are only 232 ports?  What brand is the card?

It is a national instrument card from 1998.  And I was wrong it has RS 485 ports.  There is a sticker that says it is RS-485 though the name engraved on the card says both 232 and 485.

If it is a PCI card and you have a Windows 7 compatible version of NI-Serial installed, it should work in Windows 7. If this is actually an ISA card, then there is no driver available to make it work on Windows 7. Could you post the model number of the card? It will look something like 123456A-01.

Well, that is a PCI-485 which should work fine in Windows 7. Which version of NI-Serial is installed? If you are sure you have a current version, I would recommend that you see if this board works in another machine. If it won't work in any machines, it may need to be replaced.
