AW00118508000 Acquisition Control
Basler racer Camera Link 56
Setting the Acquisition Line Rate
The rate at which the line start triggers are generated will be determined by the camera’s
AcquisitionLineRateAbs parameter:
If AcquisitionLineRateAbs is set to a value less than the maximum allowed line acquisition rate,
the parameter limits the line rate to the given value. This is useful if you want to limit the
amount of data to be transferred from the camera to the computer.
If AcquisitionLineRateAbs is set to a value greater than the maximum allowed line acquisition
rate, the camera will generate line start triggers at the maximum allowed line rate.
For more information about setting the parameter, see Section 6.1.3 on page 58.
For more information about the maximum allowed line rate, see Section 6.4 on page 87.
Exposure Time Control with TriggerMode = Off
When the trigger mode is set to Off, the exposure time for each line acquisition is determined by the
value of the camera’s ExposureTime parameter.
The minimum and the maximum allowed exposure time for each acquired line are as shown in
Table 9.
For more information about setting exposure time, see Section 6.1.3 on page 58.

Table 9: Minimum and Maximum Allowed Exposure Times
If you are using a GenICam compliant tool such as the Basler pylon Viewer and
you attempt to set the exposure time to exactly the minimum allowed or to exactly
the maximum allowed, you will see unusual error codes. This is an artifact of a
rounding error in the GenICam interface architecture. As a workaround, you could
set the exposure time slightly above the minimum or below the maximum. Values
between the minimum and the maximum are not affected by the problem.
