| Abstract: | The M-BUS is a remote communication bus for various kinds of intelligent instruments and control devices. A dedicated terminal transceiver chip FG722 is designed with M-BUS communication standard. The chip has sevral advantages, such as identifying dynamic voltage to receive, regulating the current to send, the slave power, precision, low power, low-cost and the ability of strong anti-interference. It can be widely used in the meter-reading system of intelligent water meters, gas meters, heat meters, smart grids and intelligent sensor networks, etc. |
