You must use 2-wire ferrules to create a secure connection when
connecting more than one wire to a single terminal on the NI-9232 with
screw terminal.
Each channel has a terminal to which you can connect a signal source. The AI+
terminal of the connector provides the DC excitation, when enabled, and the
positive input signal connection. The AI- terminal provides the excitation return
path and the signal ground reference.
