Hello, I am new to labview and today I got my first chance to play around with a cRio system with 2 NI 9401 DIO modules installed.
I can communicate with the cRio system without any issues, I can change the FPGA LED and can read back the chassis temperature.
However, I can't seem to get the DIO modules to work at all. First I used a scope to see if I was getting any output and I wasn't. I then decided to jump pins 16 on both modules, still can't see anything.
The pin outs for these modules are located here:

I writed pin 16 on module 2 to pin 16 on module 1 and set the write/read properties accordingly, but again for some reason this doesn't work. Attached is a screenshot of my FPGA program, any help would be appreciated. I'm sure I missed a step somewhere.
