AW00118501000 Acquisition Control

Basler racer Camera Link 53

For more information about determining the maximum allowed line rate with the current camera

settings, see Section 6.4 on page 66.

For more information about setting the camera for hardware triggering and selecting the source to

receive the ExLSTrig signal, see Section 6.1.5 on page 52.

For more information about CC1, CC2, CC3, and CC4, see Section 5.6.1 on page 31.

6.1.5.2 Exposure Modes

If you are triggering the start of line acquisition with an externally generated line start trigger

(ExLSTrig) signal, the following exposure modes are available:

 Timed exposure mode

 Trigger width exposure mode

Timed Exposure Mode

When the timed exposure mode is selected, the exposure time for each line 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

The minimum and the maximum allowed exposure time for each acquired line are as shown in

Table 6.

Table 7: 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 work around, 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.
