Basic Operation and FeaturesBasler A400k 3-27DRAFT3.8.4 Programmable AOI SequencerThe programmable area of interest sequencer feature lets the camera run a predefined sequenceof two or more areas of interest. The sequence can be triggered by the ExSync signal or thecamera’s internal control signal (free-run).Up to 32 areas of interest can be included in one sequence. Figure 3-12 illustrates a sequencethat includes two areas of interest. The camera repeats the sequence as long as the AOIsequencer feature is enabled.Figure 3-12: Area of Interest SequenceAs explained above, the sequencing can be triggered by the ExSync signal. You can trigger eachimage capture in the sequence with a separate rising edge of the ExSync signal or you can use asingle rising edge of the signal to trigger the complete sequence. The camera can also run thecomplete 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 and 3.8.4.2). The AOI list defines the areas of interest, the order in which theywill run and some other parameters. When the AOI list is complete, you upload the list to thecamera (Section 3.8.4.3). To actually run the camera according to the defined sequence, you mustfinally enable the AOI sequencer feature by enabling one of three trigger modes (Section 3.8.4.4).Line 20Line 19Line 18Line 17Line 16Line 15Line 14Line 13Line 12Line 11Line 10Line 9Line 8Line 7Line 6Line 5Line 4Line 3Line 2Line 11 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32Column 33 34 35 36 37 38Line 29Line 28Line 27Line 26Line 25Line 24Line 23Line 22Line 21Line 32Line 31Line 30
