Analog Input Signal Overview
The AI signals for the NI 6013/6014 are ACH<0..15>, AISENSE, and
AIGND. Connection of these AI signals to the device depends on the type
of input signal source and the configuration of the AI channels you are
using. This section provides an overview of the different types of signal
sources and AI configuration modes. More specific signal connection
informationisprovidedintheConnecting Analog Input Signals section.

pd = pull down
pu = pull up
DO = Digital Output
The tolerance on the 50 kΩ pull-up resistors is very large. Actual value may range between 17 and 100 kΩ.
