Programmable Aoi Sequencer - Basler A400K User Manual

3.8.4 Programmable AOI Sequencer

The programmable area of interest sequencer feature lets the camera run a predefined sequence
of two or more areas of interest. The sequence can be triggered by the ExSync signal or the
camera's internal control signal (free-run).
Up to 32 areas of interest can be included in one sequence. Figure 3-12 illustrates a sequence
that includes two areas of interest. The camera repeats the sequence as long as the AOI
sequencer feature is enabled.

Figure 3-12: Area of Interest Sequence
As explained above, the sequencing can be triggered by the ExSync signal. You can trigger each
image capture in the sequence with a separate rising edge of the ExSync signal or you can use a
single rising edge of the signal to trigger the complete sequence. The camera can also run the
complete sequence non-stop (free-run). In free-run, no ExSync signal is required.
Before you can run a predefined sequence of areas of interest, you must first create an AOI list
(Sections 3.8.4.1
will run and some other parameters. When the AOI list is complete, you upload the list to the
camera (Section 3.8.4.3). To actually run the camera according to the defined sequence, you must
finally enable the AOI sequencer feature by enabling one of three trigger modes (Section 3.8.4.4).
