Secondly check the USB cable whether it connect properly.

1. Connection check: Please make sure the connection
between the scanner and the terminal is successful. If
successfully, the power-on tone will be heard.
2. Transmission check: Please scan the sample code below. If
the sample code is transmitted, please go to S3. If the
sample code is not transmitted but there is a decoding tone,
go to S4. If the sample code is not transmitted and there is
no decoding tone, please contact technical support.
3. Barcode check: Pease rescan the same type of barcode
without defacement I transmitted it's due to defacement. If
not, please contact technical supporter.
4. Transfer software check: Please open the text file and serial
port transmission tools. If there is output in one of these
tools, please refer to the 3.1 USB connection section in this
manual for the configuration of what you need. If there is no
output, please contact technical supporter.
