Operation method:
Connect the HWT9053 to the computer through the USB to RS485 module, click
the configuration option, open the configuration bar, and click "Reset".
After restoring the factory settings, power on the module again. (This method
needs to know the baud rate of the module in advance, if the baud rate does not
match the instruction will not take effect.)
