USING POWERSCAN® D8530
undesired effect, the Autoscan Pattern Code is placed in the PowerScan® D8530 reading area which prevents decoding. Using this code as the background, code reading takes place normally by presenting desired codes to be read over the Pattern Code. Between each code read, the Pattern Code must be presented to the reader.
The Pattern Code can be printed from the file of the manual (Appendix D) available on the
In case of low ambient light conditions, PowerScan® D8530 automatically activates the illumination system. If desired, the illumination system can be enabled so that it is always active.
2.5CAMERA CONTROL
Exposure and Calibration
Three automatic control modes are available to get the best tuning of the image to be captured:
-Automatic based on entire image: camera control mode based on the analysis of the whole image. This mode works well in most standard applications. It is the default setting.
-Automatic based on central image: camera control mode based on the analysis of a restricted area positioned in the central zone of the image. This mode is suggested when reading small codes positioned in a dark and extensive background.
-Automatic for highly reflective surfaces: camera control mode allowing to read codes on highly reflective surfaces. This mode is suggested, for example, when reading codes positioned on plastic or metal surfaces.
