I/O Parameters
Shutter Speed
Unless an application is a static setup, the shutter speed setting should be configured by
the user based on their application. For dynamic applications the user should configure
the shutter speed setting, so the calibration process can optimize the gain for that setting.
The following table illustrates a general guide-line for shutter speed configurations for various
line speeds.
Note: This is a general guide line, and depends on the scanners optical configuration and
symbol element size.
Don't Calibrate
The shutter speed is fixed and is not part of the calibration process.
Calibrate
The shutter speed will be calibrated to provide the best image quality and performance.
Calibrate Fast Shutter
The calibration process will concentrate on achieving the fastest possible shutter setting
that still will still have good performance. The image quality or contrast may not be as
good as what would be achieved with the "Enabled" setting. The calibration process is not
designed to choose the fastest shutter speed that can decode a symbol, but rather to
optimize for the fastest shutter speed that still provides good image quality.
