In RS-232C interface, all the communication conditions, such as baud rate must
be consistent.

Is the format of serial command correct?
Serial commands input are effective in stand-by state.
Add a carriage return code [CR] at the end of the serial command.
Push Enter key at the end to input the serial command by typing on Terminal

memory. If the reader is turned off the power without saving settings, the reader
will start up in the previous settings next time.
An interval of 500ms between each command will avoid unwanted error during
