pin-out

[Jo-Jo]

I have two PXI-2532 matrices that I need to connected toegther to make a single 8x128 matrix.  We will be using a custom connector, so what I need to know is how do I know which pin is which column and which row.

I have the spec, but it isn't very discriptive.  All the columns and rows are preceeded by Bxx, where xx is a number from 0-15.  If I set one of the matrices to be 8x64 1-wire, I assume I need to use pins r0 throuhg r7, but how do I know which r0 through r7 to us, and which columns do I use, and how are they ordered?

Hi BenjaminS,

I believe the resource that will greatly assist you is the NI Switches Help:

http://digital.ni.com/manuals.nsf/websearch/B133DDD29F0DFCC28625746E00564E56

The NI Switches Help is installed with the NI-Switch driver, but I included the link to the compiled help manual (.chm), just in case.  If you download the above and double-click on switch.chm (or if you navigate to All Programs >> National Instruments >> NI-SWITCH >> Documentation >> NI Switches Help), then you will be able to obtain the PXI-2532 pinout information you require.  Refer to the attached pictures.

As an example of how to expand rows, for r0 you will want to short b0r0, b1r0, b2r0, b3r0 of module 1 and b0r0, b1r0, b2r0, b3r0 of module 2.

Hopefully, this will make more sense once you check out the NI Switches Help documentation.  Refer to the PXI-2532's 1-Wire 8x64 Matrix Topology information and the Terminal Block Connections section (outlined in red in 1.JPG).  You'll see how the NI TB-2641 terminal block connects banks of the NI PXI-2532 to create the 1-wire 8×64 matrix topology. There is also a figure provided to illustrate how the native banks of the NI PXI-2532 connect using the NI TB-2641, thus creating the 1-wire 8×64 matrix topology.  You'll want to make these connections yourself.

Then, all you need to do is connect the rows between modules, and you're good to go.  Hope this helps!
