Trouble Using DAQ

[popul]

Hi good day!
Can anybody please help me, i got trouble using crio 9075, ni 9477 and ni 9426..

I uploaded a program (snippet in the attachment) but i cant get any High Signal, I already check the pinouts using VOM..
I cant get any result, i already tried those pin configuration (in the attachment)..

I already tested it on CDAQ 9188XT but i got the same result..

Am I missing something?? Please Help me

The 9426 needs an external power supply to be connected to the Vsup.  So your power supply ground should go to the COM of the 9477 and the output voltage to Vsup of the 9426.  After that, you can just directly connect your channels.
