PXI-2531 512 or 256 inputs.

Hello,

 

I have a question for the PXI-2531 and PXI-2532.

It states that it has 512 single point inputs.

Looking at the connector I can only see 256 inputs.

 

Why is this?

 

gr,

Where do you see that it has 512 inputs? It has 512 crosspoints.

What's the difference between cross points and inputs?

Basic topology explained here. This is basic stuff. You really need to understand this in order to use the board. Think in terms of rows and columns. The rows and columns (i.e. 4x128) are inputs/outputs. The crosspoints are the switches that connect a specific row to a specific column.
