SYSTEM
The DLL2020 can be controlled from the POS system via the RS232
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):
Command Description Hex.
Ctrl - E Power-up re-initialization 05 Hex
Ctrl - N Enable decoding 0E Hex
Ctrl - O Disable decoding 0F Hex
Ctrl - R Sleep 12 Hex

When the scanner decoding is disabled, the scanner motor will remain
switched-on until the scanner goes into sleep mode.
