This chapter describes the instructions necessary for installing the 
DLL2020 scanner. 
Due to many POS systems on the market, a large number of 
communication cables is available. Make sure that you have the right 
cable to connect the scanner to your POS or computer. 
NOTE 
The scanner and the host system must be switched off 
before starting the installation of the scanner. By 
following this precaution you prevent any electrical

and convenience for the operator.

computer.
