Unipolar X Bipolar X single-ended X diferential

Hello for all,

I'm wondering about the following: in a daq-board, the Unipolar/Bipolar
function determines the arrangement (single-ended / diferential) of the
circuit or not?  Can I do the acquisition in a configuration like this:
Bipolar in single-ended mode in the pcm-3718, for example??? (the board
isn't the problem, the configuration is...)

thanks
