Basler ace USB 3.0 77
The following trigger source events are available:
All cameras except acA3800-14 and acA4600-10 cameras: Exposure Start is currently the
only trigger source event available to start Timer 1.
acA3800-14 and acA4600-10 cameras only: Flash WIndow Start is currently the only trigger
source event available to start Timer 1.
If you require the timer signal to be high when the timer is triggered and to go low when the delay
expires, simply set the output line to invert.
Timer 1 Active can serve as the source signal for output line Line 2 and for the GPIO lines Line 3
and Line 4 if configured for output. For information about selecting the Timer 1 Active as the source
signal for an output line, see Section 5.12.1 on page 69.
5.12.6.1 Setting the Timer Trigger Source
1. Use the Timer Selector to select Timer 1.
2. Set the value of the Timer Trigger Source parameter to Exposure Start. This will set the
selected timer to use the start of exposure to start timer 1.
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 37.
To set the timer trigger source for Timer 1:
The Exposure Start signal is not available for acA3800-14 and acA4600-10
cameras. For these cameras, the Flash Window Start signal is available as the
Timer Trigger Source.
