Connection operations are entered in a scan list that is downloaded to the memory of the switch module. The first entry in the scan list is executed when the scan is initiated. The trigger settings determine how the switch advances through subsequent entries in the list. The scan list can be executed once or repeatedly.

Refer to Controlling and Triggering an SCXI Switch for information about controlling and triggering your switch module.

Note Note  Some devices may not support scanning. Refer to your device book for more information about supported features.
