Specifies whether to tristate lines specified with ChangeDetect.DI.RisingEdgePhysicalChans and ChangeDetect.DI.FallingEdgePhysicalChans that are not in a virtual channel in the task. If you set this property to TRUE, NI-DAQmx tristates rising/falling edge lines that are not in a virtual channel in the task. If you set this property to FALSE, NI-DAQmx does not modify the configuration of rising/falling edge lines that are not in a virtual channel in the task, even if the lines were previously tristated. Set this property to FALSE to detect changes on lines in other tasks or to detect changes on output-only lines.
