Creating An Aoi List - Basler A400K User Manual

• Exposure time and delay time settings represent multipliers and the actual exposure time is
equal to the setting x 4.56 µs. The range of possible settings is 1 to 4,194,303 for the expo-
sure time (4.56 µs to 19.12 s) and 2 to 4,194,303 for the delay time (9.12 µs to 19.12 s).
• 0 to 255 runs can be set. If the runs setting is 0, the area of interest will be skipped.
• The flash trigger setting can be 1 or 0 where 1 enables the flash trigger signal and 0 disables
the flash trigger signal (see also Section 2.5.8).
• If the flash trigger setting is 1 and the flash window signal is output via the flash trigger signal
(Sections
than the sum of the height of the area of interest plus the width of the flash window:
where the flash window width is calculated using the formula below:
Flash Window Width = (Exposure Time Setting - AOI Height Setting) * 4.56 µs
• If AOI trigger mode 2 or 3 is selected (see Section 3.8.4.4), the delay time setting must be
equal to or higher than the AOI height setting to avoid overlapping exposures due to subse-
quent overlapping areas of interest:

3.8.4.2 Creating an AOI List

You can create an AOI list by
• setting up a list in hexadecimal format or by
• using the AOI Editor.
By Setting up a List in Hexadecimal Format
If you create the AOI list in the hexadecimal format, you must create a HEX file. To create a HEX
file, you need a hexadecimal editor. If you do not have a hexadecimal editor, you can download a
freeware editor from the web. For example, you can download DF Hex Editor from http://www.del-
net.com/frmDFHEXEditorE.html.
Figure 3-14: AOI List in Hexadecimal Editor
Once you have a hexadecimal editor available, perform the following steps:
1. Open the hexadecimal editor.
2. Enter the settings of the AOI list one after the other in hexadecimal numbers. For example, to
enter the list shown in Figure 3-15, you would enter the hexadecimal numbers as shown in
Figure 3-16.
