The difference between 4g router and 4g DTU device

In the field of the Internet of Things, industrial 4G routers and 4G DTUs are frequently used devices that function as long-distance data transmission. So what are the essential differences between the two when they are used? Now I will take you to understand industrial router Essentially different from DTU.

The difference in usage:

Industrial 4G routers can convert Ethernet and fieldbus communication protocols. You only need to set the IP address designated by the industrial 4G router 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.

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

1. The network interface is different:

Industrial 4G routers usually have a network port, which provides wireless networking functions for network port devices. Data transmission that requires network port devices to actively access the center can be completed. Generally, industrial 4G routers will provide multiple network interface methods such as WAN port, LAN or freely switchable WAN/LAN port. The matching interface method can be customized according to the connection method in the project.

4D TU data access generally also provides a serial port or network interface, but their purpose is for dialing, not a gateway in the true sense, for example, the 4G DTU of the serial interface is dialed in the terminal device. , 4G DTU is regarded as a new network equipment of the terminal equipment, the address of the terminal equipment uses the address bound by the new network equipment; and the 4G DTU of the network interface is similar to the telecommunication ADSL Internet access, and generally requires the equipment to complete a dialing action .

2. The processing of exchange data is different

The communication server is the core of the industrial 4G router, so the central server must be installed with a host for the 4G router to communicate. All data exchanged by the device must be encrypted, decrypted, verified, and routed by it.

Use 4G DTU without other intermediate servers, but directly connect to the central server.

3. The anti-interference of the server network is different:

The use of industrial 4G routers must comply with pre-set regulations during data transmission, otherwise it will not be able to communicate correctly, reducing the possibility of unnecessary network traffic; at the same time, it can be processed according to key processing such as the serial number sent to ensure that server data will not Replayed or retransmitted.
