Internal integrated TCP/IP protocol stack.
The GPRS DTU encapsulates the PPP dial-up protocol and the TCP/IP protocol stack and has an embedded operating system. From the hardware, it can be regarded as a combination of an embedded PC and a wireless GPRS MODEM; it has GPRS dial-up Internet access and TCP/IP data function of communication.
Provide serial data bidirectional conversion function
GPRS DTU provides serial communication interfaces, including RS232, RS485, RS422, etc., which are commonly used serial communication methods, and GPRS DTUs are mostly designed to use serial data as a "transparent conversion" method.
Support automatic heartbeat, keep online permanently
One of the advantages of GPRS communication network is that it supports GPRS terminal equipment to be permanently online. Therefore, typical GPRS DTUs are designed to support permanent online function. When there is no data communication, the mobile gateway will disconnect the connection between the DTU and the center.
Support parameter configuration and save permanently
As a communication device, GPRS DTU has a wide range of applications. In different applications, the IP address and port number of the data center, and the baud rate of the serial port are all different. Therefore, GPRS DTU should support parameter configuration, and save the configured parameters in the internal permanent storage device.
