AW00098504000 Image Acquisition Control
Basler ace Camera Link 87
For more information about determining the maximum allowed frame rate with the current camera
settings, see Section 7.8 on page 117.
For more information about setting the camera for hardware triggering and selecting the source to
receive the ExFSTrig signal, see Section 7.3.3.4 on page 91.
For more information about the electrical requirements for the GPIO line when it is set to operate
as an input, see Section 5.7.2 on page 35.
For more information about CC1, CC2, and CC3, see Section 6.1 on page 49.
7.3.3.2 Exposure Modes
If you are triggering the start of frame acquisition with an externally generated frame start trigger
(ExFSTrig) signal, two exposure modes are available: timed and trigger width.
Timed Exposure Mode
When timed mode is selected, the exposure time for each frame acquisition is determined by:
 the value of the camera’s Exposure Time Abs parameter if you are parameterizing the camera
with Basler pylon.
 the value of the Exposure Time Raw register if you are parameterizing the camera via direct
register access.
If you are triggering frame acquisition with an ExFSTrig signal and you attempt to
acquire frames at too high a rate, some of the frame trigger signals that you apply
will be received by the camera when it is not in a "waiting for frame start trigger"
acquisition status. The camera will ignore any frame start trigger signals that it
receives when it is not "waiting for frame start trigger". (This situation is commonly
referred to as "overtriggering" the camera.
To avoid overtriggering, you should not attempt to acquire frames at a rate that
exceeds the maximum allowed with the current camera settings.
