It uses serial port 9600 & 8N1 to set module working parameters throughspecific instruction format. (Please refer to parameters setting for details)Notes When the mode changes from stand-by mode to others, the module will reset its parameters, during which the AUX keepslow level and then outputs high level after reset completed. It is recommended to check the AUX rising edge for user.7.
