Datalogic Scanning DLL2020-WO - Manual (Page 15)

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.
