Acquisition Control AW00049313000
90 Basler runner
Timed Exposure Control Mode
When the timed exposure control mode is selected, the exposure time for each line acquisition is
determined by the value of the camera’s Exposure Time parameters. If the camera is set for rising
edge triggering, the exposure time starts when the source signal for the line start trigger rises. If the
camera is set for falling edge triggering, the exposure time starts when the source signal falls.
Figure 32 illustrates timed exposure with the camera set for rising edge line start triggering.

For more information about the camera’s exposure time parameters, see Section 8.2.5.2 on
page 94.
Exposure Time Control Mode Off
When the exposure control mode is set to off, each acquired line will be exposed for the full period
of the source signal for the line start trigger. This will be true regardless of whether the camera is
set for rising edge or for falling edge triggering. Figure 33 illustrates exposure with the exposure
mode set to off.
