In order to scan programming barcodes in the WDI4500 Users Manual, the scanner must have parameter scanning enabled. Normally, parameter scanning is only disabled to prevent users from modifying saved configurations. These barcodes are also found in Chapter 2 - Interface Setup in the Wasp WDI4500 Users Manual.
