Pantera SA DS -21-02M30 and DS-22-02M30 User’s Manual 31 Guidelines and Rules for Setting the AOI When setting the area of interest, be aware that: • Changing the area of interest settings while the camera is operating in mode 2 will also change the set or ssf settings. Always re-enter set and ssf values after changing the AOI while operating in mode 2. To check settings, enter the command gcp. The help screen will display one of the following sets of messages: Condition set and ssf settings are correct and camera is running in exposure mode 2 set and ssf settings are incorrect and camera is running is exposure mode 2 camera is running in exposure mode 3, 4, or 6 Help Screen Message Frame Rate Settings within round off error: YES Exposure Time within round off error: YES Frame Rate Settings within round off error: NO. Re-enter ssf cmd Exposure Time within round off error: NO. Reenter set cmd Frame Rate Settings with round off error: NA Exposure Time within round off error: NA • Changing the AOI while operating the camera in mode 6 can result in an invalid set result. Always re-enter your set value after changing the AOI when operating in mode 6. • The camera will ignore any EXSYNC signals that occur quicker than the readout rate. • The exposure time setting cannot be greater than the frame time. The minimum frame time cannot be less than the readout time. If either of these conditions are violated, the camera will automatically adjust these settings. • If you are using binning, the window start/end values will be rounded using the following equations: Binning Start Value = INT [(Input Value-1)/Binning Factor] x Binning Factor +1 Binning End Value = [INT {(Input Value-1)/Binning Factor} x Binning Factor +1]+ (Binning Factor –1) • If you are using the color (DS-22-02M30) 2M30, the resolution of the color filter array Bayer Pattern (2x2) restricts the size and position of the AOI. You must specify an odd number for the start row and an even number for the end row. If you specify an even number for the start row, the Bayer pattern is reversed and the resulting image is corrupted. Timing Considerations When operating the camera in either exposure mode 2 or exposure mode 6, the camera timing may be altered. The electronic shutter cannot fire while the sensor is dumping unwanted data (regions 3 and 5 in Figure 15). The electronic shutter will fire as soon as the dump is complete and the value set for the exposure time will be altered accordingly. You will not be told explicitly that the exposure time has been altered, but you can obtain the new value by entering the gcp command. DALSA 03-32-10150-01
