1.2 Scanning bar codes with the DLL2020-WO
The DLL2020-WO is an omnidirectional scanner featuring a 4-directional
scan field with a 16-lines scan pattern. Bar codes can easily be read by
presenting them to the scanner. The scan volume is illustrated in the
figure above. The optimal reading zone lies between 3 and 15 cm from
the scanner window. However, bar codes can still be read up to 25 cm
(10 inch) from the scanner window.
