I am not getting this. I does not help that my Omni VI manual does not 
have pin numbers on the DC Power Input Board schematic. I don't see how 
the power switch on the Omni VI can turn the 9420 on and off. It looks 
like just plugging in Omni VI into the 9420 would turn it on, regardless 
of the power switch postion. I have never tried using the 9420 to power 
the Omni. Never made up a cable to do it. Still I would like to 
understand this circuit, in case I ever want to use it that way. Anybody 
out there who can clarify this?
