Can I use two NI PCI-232/4 cards in one PC without conflict?

[dcjoey]

I currently have a system with one NI PCI-232/4 card, all ports being used.

Trying to decide between getting a second card or upgrading the current card to one with more ports. If possible I would just like to add a second card but I want to make sure there won't be a conflict using two of the same card.

Hi dcjoey,

You can use two cards of the same type in the same computer, the system should have no issues telling them apart. The new 232 ports will have unique numbers just like the 232 ports on your first PCI-232 card and your built in COM port. For example if you have 2 PCI-232/4 devices and one built in COM port, you should see COM 1 (built in), COM 2, COM 3, COM 4, COM 5 (first card), COM 6, COM 7, COM 8, COM 9 (second card).

Let us know if you need any more information.

Thanks
