How DTU works and four core functions of DTU?

How DTU works

The communication between the DTU and the server is initiated by the GPRS DTU (client), and the server responds to the DTU by sending back feedback or accepting communication. The DTU end and the server end together form an application system based on GPRS and INTERNET network communication.

Compared with the DTU side, the server side is equipped with more complex applications, which can accept any communication request initiated by the DTU side and detect the communication status in the link at any time, so as to realize real-time data collection, database services and other applications.

The four core functions of DTU?

1. Support automatic heartbeat and stay online permanently

2. Provide two-way conversion function of serial data

3. Internally integrated TCP/IP protocol stack

4. Support parameter configuration, permanent storage
