Hi. I'm working on a project where I am going to be using a PXI-2532 and a TB-2641 to set up an 8 x 64 switch matrix. I need an possible solutions for an interface board that will take the signals from the 3 ribbon cables from the TB-2641 and route them to either terminal blocks or some connector that I can then wire my measurment signals into. I was hoping to use a 90 pin femal Elco connector, but right now will look at any options. Please let me know of any interface board solutions that are out there for me to look at.

Are you aware of the SCB-264x. This is the solution National Instruments provides for connecting signals to the PXI-2532 and TB-2641. The ribbon cables from the TB-2641 connect to this terminal block and then there are screw terminals for all of your signals.
The best image of what this connector block looks like is found on page 6 of the NI-264x Installation Instructions (click the Adobe Acrobat icon to view the document).

Thanks Eric. That was exactly what I was looking for. For some reason when I clicked on the PXI-2532 and the TB-2641, the website didn't give the option of this connector block. That is why I couldn't find it!

No problem Doug,
The SCB-264x is just listed as an accessory right underneath all of the terminal blocks and with the cable options. If you contact an NI sales representative when trying to configure a system, they will be able to help you pick all of the correct accessories you need.
I will also recommend you check out our tutorial How to Connect Signals to the PXI/PXIe-2532 that walks through all of the components you'll have and the steps necessary to connect them in your system.
