The 68-Pin connector provides all I/O signals for the board:
For Singled-Ended analog inputs connect GND to ADC COMMON.
A Note About Unused Analog Inputs:
Any unused analog input should be connected to ground with a
short jumper wire; either in the mating connector cable, or on the
breakout terminal board. This will reduce / eliminate crosstalk
which, if left unchecked, can influence measurements of adjacent
connected
input channels.
