Is the host port settings the same as the reader port settings?
Make sure the connection and the communication settings (e.g. Baud rate,
Character format, COM port number for RS232C settings).
The reader port is set by the serial command “COMFROM”. If the port is set to
RS232C (COMFROM=0), both way LAN data communication between the
reader and the host would not work.

Symbol cannot be decoded
Is the symbol-code settings correct?
Make sure that the symbologies and the digit number are set up correctly. If the
settings differ from the input symbologies, the reader would not decode the
image.
Are the reading distance and the print quality suitable?
To ensure the reading distance from the code to the reading window must be
within the specified reading distance.
If the code is damaged or the print quality is low, it may not be decodable even if
the reading depth requirements have been met.
Is the reading window clean?
The quality of captured image is affected by the condition of the reading window.
Dust, dirt, etc. on the reading window may alter the reading performance. Clean
with a lens cleaner or similar non-abrasive method.
