The dBarScanJ Class will behave as a Testware version (returning scrambled barcode scans) unless correctly licensed.
Single computer version of the components are licensed for use only on a single computer. Developer versions permit applications built with the dBarScanJ to be distributed up to a maximum distribution of 10,000 copies.
To activate the class, the product serial number must be supplied as the Serial property before calling any of the scan methods, e.g.
scanner.setSerial("12345")
or
scanner.setParam(“SERIAL”,"12345");
