PCI 4474 - can it send some information out?

PCI 4474 - can it send some information out?  As I understand there are 4 inputs, but there is one more plug- what it is for?

Thing is, I need to make Labview switch some relays, but for a moment we have only this card... I'm making laboratory work controlled via internet and would like to have option to switch between different resistors.

The 4474 has no ouputs, the other connector is for a digital trigger input, I believe. You may want to refer to the manual for specific information.
