Analog Input Signal Overview
The analog input signals for the NI 6034E/6035E/6036E device are
ACH<0..15>, ASENSE, and AIGND. Connection of these analog input
signals to your device depends on the type of input signal source and the
configuration of the analog input channels you are using. This section
provides an overview of the different types of signal sources and analog
input configuration modes. More specific signal connection information is
provided in the Connecting Your Analog Input Signals section.

AI = Analog Input DIO = Digital Input/Output pu = pullup
AO = Analog Output DO = Digital Output
The tolerance on the 50 kΩ pullup resistors is very large. Actual value may range between 17 and 100 kΩ.
