Note:
If you choose to calibrate the reader by sending a
<@CAL>
command, a decode is also required
for the calibration process to be completed successfully.
Note:
This table shows guidelines for exposure settings based on various line speeds. The settings
shown depend on the reader’s optical configuration and on symbol element size.
When disabled, exposure is fixed and is not part of the calibration process.
When enabled, exposure is calibrated to provide the best image quality and performance for the
symbol present in the field of view. Calibration requires that a decodable symbol be placed in the field of
view, as feedback from the symbol decoding process is used to select the best exposure setting. If a
symbol is not decoded the process will result in a fail condition. Exposure is enabled by default.
Quick Calibrate
uses a basic histogram profile to bring the image into an acceptable dynamic range
that will provide good contrast for decoding symbols in most environments. This routine is optimized for
a fast process to execute in under 1 second.

Exposure
Definition:
Unless the application is static, exposure should be configured based on
the application’s line speed. The table below is a general guideline for
exposure configurations at various line speeds.
