Working Mode of IOT Cellular Modem
1.HTTP Client
Support serial data transmission to designated server via HTTP.
2. TCP Client
The serial server actively initiates a TCP connection to the server. If it fails, it will continue to reconnect until it succeeds. If the connection is successful, the server and the serial device can perform two-way transparent data transmission.

- IOT Cellular ZHC4941 can be applied to an intelligent remote meter reading system. According to customer needs, the monitoring center can realize remote shutdown of water and electricity to terminal users through the data acquisition control terminal. When the transmission data is abnormal, the monitoring center can alarm and display. Relevant staff can repair the field instruments in a targeted manner. Mainly used in factories, hotels, schools, hospitals and other large users of water consumption and the total amount of water in various regions, and remote meter reading of electricity consumption of large users such as substations, distribution stations, enterprises and institutions, schools, hospitals, etc.
