TimingChangeDetectionDITristate Property
Specifies whether to tristate lines specified with ChangeDetectionDIRisingEdgePhysicalChannels and ChangeDetectionDIFallingEdgePhysicalChannels that are not in a virtual channel in the task. If you set this property to , NI-DAQmx tristates rising/falling edge lines that are not in a virtual channel in the task. If you set this property to , 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 to detect changes on lines in other tasks or to detect changes on output-only lines.
