Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp

Breaks the connections between channels specified in disconnection list. If no connections exist between channels, NI-SWITCH returns an error. In the event of an error, the VI stops at the point in the list where the error occurred.
