Issue Details

I have upgraded from PXIe-2532 and TB-2640 to PXIe-2532B and TB-2640B, but TB-2640B has different connection labels than TB-2640. How do I change my ribbon cable connections for use with the new terminal blocks?

Solution

NI PXI/PXIe-2532B (NI 2532B) is designed as a replacement for PXI/PXIe-2532 (NI 2532). The cables currently used in an existing NI 2532 system with the TB-264x can be swapped directly to plug into a system with the NI 2532B and a TB-264xB.

Refer to the following images to see how current configurations cable connections can be directly swapped from the NI TB-2640 to the NI TB-2640B.
