I have a PXI 6515 digital IO card and a PCI 6527 digital IO card on another computer. I have to do digital handshaking between these two computers. My question is can I connect directly from the digital input connector block of one card to the digital output conector block of another card and vice versa? If I cannot do what are all the possible solutions? If one is sink and other is source can I connect them directly or do I need use a signal conditioning between the cards no matter what kind of digital IO cards they are? I appreciate your help.
Since both the PXI-6515 and PCI-6527 have static timing, you will need to handle the handshaking in software. But other than that, there should be no difficulty in setting up handshaking between these two cards since they use the same logic (24 V).
