Applying Trigger Signals
The paragraphs above mention "applying a trigger signal". There are two ways to apply an
acquisition start or a frame start trigger signal to the camera: via software or via hardware.
To apply trigger signals via software, you must first select the acquisition start or the frame start
trigger and indicate that software will be used as the source for the selected trigger. At that point,
the Basler pylon API or direct camera register access can be used to apply a software trigger signal
to the camera for the selected trigger.
To apply trigger signals via hardware, you must first select the acquisition start or the frame start
trigger. You then select one of the camera’s physical inputs to be used as the source for the selected
trigger. At that point, each time the proper electrical signal is applied to the selected input, an
occurrence of the selected trigger signal will be recognized by the camera.
