Incorrect Pin Assignment in PXI-2522 Documentation

Updated Dec 3, 2020

Issue Details

When I configure Normally Open (NO) for both Relay 43 and Relay 44, they are actually configured as Normally Close (NC) and vice versa. All other relays on the same module are working fine.

Does this indicate I have a faulty PXI-2522 module?

Solution

NI's Research and Development (R&D) team has verified this issue is a mistake in NI documentation for the PXI-2522. NC43 should be pin D6, and NO43 should be pin D8 while NC44 should be pin E6, and NO44 should be pin E8.
