You can set the Trigger Selector and the Timer Trigger Source parameter value from within your
application software by using the Basler pylon API. The following code snippet illustrates using the
API to set the selector and the parameter value:
camera.TimerSelector.SetValue(TimerSelector_Timer1);
camera.TimerTriggerSource.SetValue(TimerTriggerSource_ExposureStart);
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 43 .

The Exposure Start signal is not available for acA3800-14 and acA4600-10

Section 6.6.2 on
page 132 ) timer 1 will start nonetheless when exposure starts for
the last row of the current ROI. This assumes that Flash Window Start is selected
as the Timer Trigger Source.
