First connect the barcode scanner to the host and power supply. Sometimes the power supply is provided by the host. Otherwise, the external power supply will be required.
Shut down the host first, and then turn it on after the connection to avoid damage to the machine and interface.
Next, set the communication mode between the barcode scanner and the host, and scan the barcode in the user manual to set it.
After the setting is completed, you can scan and upload the data to the computer.
