Note 2: If the shutter pulse is requested in region 5, it will be fired in region 4. The new exposure time value depends on the AOI size and the frame rate. There are four different cases and are analyzed below (refer to Figure 15): Case A: Not affected by fast dump. The exposure time is set to the requested value. Case B: The exposure time requested requires that the electronic shutter be activated in region 3. The electronic shutter cannot be activated during the fast dump so the integration time will be reduced to the new value = Frame Time – Readout. Case C: The exposure time requested requires that the electronic shutter be activated in region 4. The electronic shutter will be fired in the same region and the exposure time is set to the entered value +/- the uncertainty error. Case D: The exposure time requested requires that the electronic shutter be activated in region 5. The electronic shutter cannot be activated during the fast dump so the integration time will be reduced to the value = Frame Time – Readout + Region 3 + Region 4. DALSA 03-32-10150-01

Pantera SA DS -21-02M30 and DS-22-02M30 User’s Manual 33 Setting the AOI To set the area of interest, use the command: Syntax: Syntax Elements: wse q i x1 y1 x2 y2 q i x1 y1 x2 y2 Window sequence id to use. In the 2M30, the sequence id is always 0. Window to set. In the 2M30, the window id is always 0. The column start identifier with a range of 1 to the number of the horizontal pixels in the camera. Since the 2M30 only allows you to set a vertical area of interest, this value is always 1. The row start identifier with a range of 1 to an integer less than the row end identifier (y2). If you are using the color (DS-22-02M30) 2M30, this value must be odd in order to preserve the color filter array Bayer pattern. Otherwise, the image will be corrupted. The column end identifier with a range of 1 to the number of the horizontal pixels in the camera. Since the 2M30 only allows you to set a vertical area of interest, this value is always 1. The row end identifier with a range greater than the row start identifier (y1) to the number of vertical pixels in the sensor. If you are using the color (DS-22-02M30) 2M30, this value must be even in order to preserve the color filter array Bayer pattern. Otherwise, the image will be corrupted. Notes: Changing the AOI settings while in mode 2 or 6 will also change the set or ssf settings. See Guidelines and Rules for Setting the AOI on page 31 for more details. Also, changing the AOI settings while in modes 2 or 6 may alter camera timing. See Timing Considerations on page 31 for more details. Example wse 0 0 1 301 1 900 DALSA 03-32-10150-01
