Unwanted or Wrong Character(s) When Reading a Barcode

Keyboard Layout

Problem: mixed up characters like "-" is read as"/".

Solution: change the keyboard layout setting in your keyboard wedge scanner.

These problems can occur with scanners connected to the keyboard cable of your system. The scanner translates the barcode into keystroke sequences - these keystrokes are language dependent. To solve the problem make sure that the "keyboard language" of the scanner matches the language of the used keyboard. Please check out the configuration manual of the scanner - usually the manual contains some configuration bar - codes which must be scanned with the scanner.

Code Page (2D Barcodes)

For encoding characters outside of the standard ASCII table (0-127) you can choose different code pages (with specific 2D bar codes). If you choose a non-standard code page (other than default) you can get mixed up or non readable characters. Whenever possible you should always use the default code page of the respective 2D bar code. If you try to encode special characters (like Ä or Ñ), make sure that the 2D symbology in use is able to encode them with the default code page.

Scanner Configuration

If you get unwanted characters or line feeds, when scanning, this can be introduced by a wrong scanner configuration. To solve this problem refer to the scanner’s manual to verify the so-called prefix, suffix and symbology identifier settings.
