Image Acquisition Control
Basler aviator Camera Link 71
For more information about determining the maximum allowed frame rate with the current camera
settings, see Section 5.7 on page 90.
For more information about setting the camera for hardware triggering and selecting the source to
receive the ExFSTrig signal, see Section 5.3.3.3 on page 73.
For more information about the electrical requirements for line 1 or line 2, see Section 2.8 on
page 26.
5.3.3.2 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 the camera is set for rising edge triggering, the exposure time starts when the ExFSTrig signal
rises. If the camera is set for falling edge triggering, the exposure time starts when the ExFSTrig
signal falls. Figure 21 illustrates timed exposure with the camera set for rising edge triggering.

For more information about setting the exposure time, see Section 5.3.3.3 on page 73.
