I need to use a PXI 4110 power card to generate a 28V 1A voltage source. I read this article http://www.ni.com/example/30356/en/ to find out how to accomplish that by stacking channels on a singular card. My problem is that I have 2 other similar cards that do not stack channels but all cards connect to a circuit board, and they all end up sharing the same ground. Will my stacked card's configuration adversely affect the ability of my other cards to produce their required voltages due to the shared ground?
I also looked at http://digital.ni.com/public.nsf/allkb/F0893906EF4C08EE8625727A006DD89B?OpenDocument but I'm not sure that offers a better option either.
