Making a Connection
During scanning, a typical scan list entry is ch2->com;. This entry routes the signal connected to CH2+ and CH2– to COM+ and COM–, respectively.
You can also route both signals (COM+ and COM–) to the High-Voltage Analog Bus (AB+ and AB–) by using the scan list command com->ab, or by using the niSwitch Connect Channels VI or the niSwitch_Connect function with parameters com and ab.
