Wiring based on smart home SMS controller

The COM1 port on the back of the SMS controller is the communication bus interface (8P8C), and the COIV12 is the communication bus expansion interface (8P8C). Insert the bus crystal head into one of them to connect the system bus; on the front there is a standard RS232 serial communication interface through RS232 The cable is connected to the serial port of the computer. The serial port is also the interface for the computer management software to access the home system. On the side is the slot for the mobile phone (SIIVI card). Use a toothpick or pencil to press the small yellow button to pop up the phone card tray. Place the phone card in the tray and push the tray back into the slot.
