that scanned information will appear at the PC. A software driver and
correct configuration setting are also required for proper
communication to occur.
Caution

must meet the requirements for SELV (Safety Extra Low Voltage) according to EN/IEC
60950.
To maintain compliance with standard CSA C22.2 No. 60950/UL 60950 and norm
EN/IEC 60950, the power source should meet applicable performance requirements for
a limited power source.
