2.5.5. High-Speed Inputs
High-speed inputs 20 and 21 can be used as general purpose inputs or as the trigger signal for high
speed data collection. Refer to the DriveDataCaptureConfigureTrigger() function topic in the Help file
for more information.
You can use the
external PSO synchronization functions
to synchronize waveform generation with
an external synchronization signal. When you activate this feature, the PSO Waveform module will
not generate the configured waveform when an output event is received until the rising edge of the
synchronization signal occurs.
