Set Baud Rate
The default baud rate of the reader after power-on is 115200 BPS. At present, only 9600~115200 are applicable. When successful operation is returned after setting, it is better to have a delay of 10MS before sending other operation commands to the reader. The default initial baud rate after the reader is powered on or reset is 115200.
