34980A Relay Card 34939A - Relays not closed using Labview

I had a least one (1) 34939A Relay card that I proved I could manually open and close multiple  relay resources individually in Nov 2015.
I could not close in Labview (2012) using the certified 34980A Switch Control (open/close).   Now a second card is performing is similar fashion.

I am trying to close 2002, 2006, 2007, 2010, 2012, 2014. Resource 2010 is shown as closed under Switch Status VI however, I measure open at the cable end
that attaches to my unit under test. 

Any suggestions?

Thanks,
