1.4 Maintaining the scanner

The DLL2020-WO scanner requires little maintenance. Only occasional

cleaning of the scanner window is necessary in order to remove dirt and

fingerprints. The scanner can be cleaned during operation. To this end use

a non-abrasive glass spray cleaner and a soft lint-free cloth only.

1.5 Controlling the scanner from the pos system

The DLL2020-WO can be controlled from the POS system via the RS232C

interface. Controlling is accomplished by transmitting the following single-

byte commands to the scanner. In the Datalogic default setting the

following commands are available (more details upon request):

When the scanner is disabled, the scanner motor will remain switched-on

until the scanner goes into sleep mode.
