Funtion Usage
A bank consists of 16 main unit channels, allocated to a number of connect DBK cards. DBK cards in a single
bank must be all of the same type. The daqAdcExpSetBank function must be called once for each card in
the bank. For example, if four 4-channel cards (such as a DBK7) are used in the first expansion bank, you
must call daqAdcExpSetBank 4 times with channels 16, 20, 24, and 28.
