2. If necessary, correct these settings:
– The exposure settings
– If you wish to read an EAN13 code instead of a data matrix code, for example, press the button "Recognize code".
The reader starts code type recognition and remembers the code type found for later read processes.
– In order to find the correct image acquisition time for moved objects, correct the trigger settings.
– To rectify strong irregularities through the optics (rarely necessary), correct the distortion.
Note
If exposure = Auto, the code must be completely in the image after the triggering until the automatic exposure is
completed (approximate value: 50 to 100 ms).
3. If you make modifications, save your new settings by clicking the "Apply" button.
Result
You have successfully commissioned the reader. You can now read codes for your application. You can now make specific
