SMS controller function and main technical parameters

1. The function of SMS controller

(1) Up to 5 groups of administrator numbers can be stored.

(2) SMS or ringing mode controls the on/off of electrical equipment.

(3) Real-time detection of the change of the switch quantity, reaching the limit value to alarm the administrator. Through various sensors, temperature/humidity, infrared and smoke alarms can be realized.

SMS controller wiring

The COM1 on the back of the SMS controller is the communication bus interface (8P8C), COM2 is the communication bus expansion interface (8P8C). Insert the bus crystal head into one of them to connect the system bus; the front has a standard RS232 serial communication interface through the RS232 cable. The cable is connected to the serial port of the computer. The serial port is also the interface of the computer management software to access the home system. On the other side, there is a SIM card tray slot. 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.
