Set the equipment address by software, refer to the communication protocol section. Typical scenarios SM1882B can extend the communication distance to the longest 1200 meters through the network mode of RS485 bus, which can effectively solve the problem of too short connection distance. The following figure is RS485 networking structure chart based on SM1882B sensor typical air pressure monitoring and control. Each SM2181B sensor has a node number, a small system that can place 1-15 SM1882B sensors. Because each SM1882B s
