NI 9207E Operating Instructions and Specifications
Connecting Voltage Channels
You can connect differential or single-ended voltage signals to the
NI 9207E voltage channels.
Connecting Differential Voltage Signals to the NI 9207E
You can connect grounded or floating differential signals to the
NI 9207E voltage channels. Connect the positive voltage signal to
AI+ and the negative voltage signal to AI–. To connect grounded
differential signals to the NI 9207E, you must also connect the
signal reference to COM, as shown in Figure 4.
