Dear all,
I am using a PCI-6221 DAQ card connected to a BNC-2090A rack mount. The digital I/O sping terminal block on the rack mount is a shown in the image bellow. The PCI-6221 card has 3 ports of digital I/O with 8 lines for each port. I tested which line corresponds to which terminal and came up with the following representation shown in red, where e.g. P2-2 corresponds to Port 2 - Line 2 etc. However, it seems that Port 1 - Line 0 is not represented by any of the sping terminals.
Is there a way to obtain an I/O on the rack mount for this particular line so that I have 24 lines available in total instead of just 23? Any suggestions would be really appreciated.

Hi,
I think you are correct that the PFI0 line is not represented by any of the spring terminals. It looks instead like it's represented by a BNC Connector. You can see that on page 2-1 of the BNC-2090A manual:
