Synchronize counter outputs with second one inverter from the first

I am using a NI USB-6363 and need to synchronize counter outputs with second one inverter from the first. This seems like a trivial thing for the powerful DAQMX libraries. I found a help file topic and forum thread content that give some hint it is possible but still the functions to use elude me.  Sorry for the cross post but only discovered this more specific forum after posting in LabVIEW general forum

The DAQ-Mx help under Counter Sychronization say "share the CO Counter Timebase and Start Trigger signal". I can't find an example of how to do this? Also, I need to have the second counter output (PFI1) be the inverse of the first counter output (PFI0). 

I found this forum thread https://forums.ni.com/t5/Counter-Timer/synchronize-two-counter-outputs-on-6071E-card/m-p/2772312#M12030
that says "Trigger one counter with the internal output of the other", but I am not clear on how to do that
