Flash Window Signal - Basler DART BCON SERIES User Manual

Image Acquisition Control
For example, assume that the camera is mounted on an arm mechanism and that the mechanism
can move the camera to view different portions of a product assembly. Typically, you do not want
the camera to move during exposure. In this case, you can monitor the ExpAc signal to know when
exposure is taking place and thus know when to avoid moving the camera.

Fig. 34: Exposure Active Signal on Cameras with a Global Shutter
When you use the exposure active signal, be aware that there is a delay (in the
range of microseconds) in the rise and the fall of the signal in relation to the start
and the end of exposure.
To select the Exposure Active Signal as the source signal for an output line:
1. Use the LineSelector parameter to select output line Line 1 or Line 2.
2. Set the value of the LineSource parameter to the exposure active output signal.
You can set the LineSelector and the LineSource 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.LineSelector.SetValue(LineSelector_Line1);
camera.LineSource.SetValue(LineSource_ExposureActive);
For more information about changing the selection of an output signal as the source signal for the
output line, see Section 8.2.1 on
9.6.2
