DTU communicates with the data center mainly by actively initiating a communication connection with the data center. Because DTU is on the mobile intranet and the IP address is not fixed. Therefore, the DTU can only actively connect to the data center, but the data center cannot actively connect to the DTU. This requires the data center to have a public IP address. With the advent and further development of the Internet era, there are more and more network devices, and IPv4 address resources are about to be exhausted. These addresses may not last long. Although IPv6 is now available, IPv6 has not officially entered the commercial stage. The depletion of IPv4 addresses means that Internet service providers will no longer be able to apply for IP addresses for newly connected devices to the Internet. Many devices in Zhaocheng now use intranet IP addresses. In order to save IPv4 address resources on the public network, many broadband users no longer allocate public IP addresses to their broadband, causing DTU to be unable to connect to the data center.
The Zongheng cloud transparent transmission function of Zongheng Intelligent Control DTU perfectly solves this pain point problem, covering remote configuration, remote control, virtual serial port, support for local servers, and support for use without public network IP, etc. Users do not need to understand the cumbersome process of communication between DTU and data center. They can remotely send DTU data to a local computer through a few simple configurations. It also supports virtual serial ports and can be connected to host computer software such as configuration.
