The machine USES the I2C bus control technology and microprocessor IC1213 through the bus system is connected to all the accused of integrated circuit. Microprocessor with the accused is two-way information transmission between integrated circuit, not only the microprocessor to be accused of integrated circuit signal control, is accused of integrated circuit and microprocessor was to send response signal, the microprocessor according to the response signal and the bus communication situation. To test the working state of the rectifier machine. Every time, when the phone is switched on the microprocessor IC1213 to check each serial data line and a serial clock line whether there is open circuit, short circuit fault, the articulated in various total inspection by the accused under the integrated circuit, and the inspection results recorded by bus system memory IC1211. When the I2C bus or some accused the malfunction of the integrated circuit to produce sound, light, fault figure, but does not affect the operation of the I2C bus, the machine can continue to run; If the fault is serious, the microprocessor IC1213 will close the luminance channel protection measures, and provide information of self-check, when serious problems such as over-current, over-voltage, may cause damage of components, microprocessor output from 33 feet standby control voltage, enter standby state protection. dEmservice manual download site
