Pantera SA 2M30 - Frame Grabbers

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.
