What is the difference between an industrial router and a DTU?

Industrial routers, like DTUs, implement wireless network data transmission functions, and the difference between the two is mainly distinguished from three aspects: appearance interface, usage method and application environment.

Industrial router and DTU appearance interface

The appearance interface of the 3G/4G industrial router usually has a network port, which provides wireless networking functions for the network port device, and the data transmission can be completed only by the network port device actively accessing the center.

Usually the router will provide a variety of network interface methods such as WAN port, LAN or freely switchable WAN/LAN port. You can customize the matching interface method according to the connection method in the project.

The appearance interface of DTU generally only provides serial interface networking. Mainly used for two-way transparent transmission between serial port data and IP data.

And some projects need to use both a network port and a serial port. What should I do? In the current era of rapid technological development, routers and DTU functions have been integrated, such as the Yuncheng industrial router, which has a WAN port + N LANs It also has RS232/485 serial port equipment, which integrates multiple functions.

How to use industrial routers and DTU

1. Industrial routers can convert Ethernet and fieldbus communication protocols, and only need to set the designated IP address as a gateway in the terminal device. If the designated IP address (or designated IP address segment) is not set, the communication function cannot be realized.

2. The main purpose of DTU is to realize dial-up, not a gateway in the true sense. For example, after 4G DTU is connected to the terminal device to complete the dial-up link, the DTU can be used as a new network device, and the terminal device address can use this DTU binding address.

Industrial router and DTU working environment

1. Industrial routers usually have VPN/APN functions and private network encryption, which is suitable for projects with higher security requirements, such as video surveillance for examinations, street lamp monitoring, oil field and oil well monitoring, financial industry self-service terminals, drone room monitoring Wait.

2. In addition, the industrial 4G router with WIFI function is suitable for outdoor WIFI wireless signal coverage projects and similar bus WIFI, shopping mall WIFI sharing projects.
