Trigger Sharing
You can synchronize devices by sharing trigger signals.
For example, if you configure the start trigger of a DAQmx Acquire step with the Trigger type set to Digital, you can select any available trigger signal provided by the other devices currently in the project in the Trigger source pull-down menu. When you select one of these trigger signals, LabVIEW SignalExpress routes the trigger signal between the master and the slave and controls the master and slave execution. LabVIEW SignalExpress initializes the slave device before the master device so the slave device can receive the trigger signal.
