The difference between the 4g router with ethernet and 4g DTU de
1. Appearance interface The appearance interface of a 4G router with ethernet usually has a network port, which provides wireless networking functions for network port devices. Data transmission that requires network port devices to actively visit the center to complete. Usually 4G router routers will provide multiple 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 4G DTU is generally only provided Serial port interface networking. 4G DTU is mainly used for two-way transparent transmission between serial port data and IP data.
2. How to use The 4G router can convert Ethernet and fieldbus communication protocols. You only need to set the IP address designated by the 4G router as a gateway on 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, after the 4G DTU is connected to the terminal device to complete the dial-up link, the 4G DTU can be used as a new network device, and the terminal device address can use this 4G DTU binding address.
3. Application environment 4G routers usually have VPN/APN functions and private network encryption. In addition, industrial 4G routers with WIFI function are suitable for outdoor WIFI wireless signal coverage projects and similar public bus WIFI, shopping mall WIFI sharing projects. The 4G DTU application in the field terminal has a relatively scattered transmission distance, and the data communication rate is relatively high. Therefore, the 4G DTU real-time performance can meet most industrial fields, and is usually used as a data acquisition and monitoring system. Such as remote monitoring systems for charging piles, environmental monitoring systems, real-time monitoring of energy consumption, and monitoring applications for dam water conservancy projects.
4. 4G DTU data access generally also provides a serial port or network interface, but their purpose is to dial, not to be a gateway in the true sense, for example, the serial interface 4G DTU is used in the access terminal equipment After dialing is completed, the 4G DTU is regarded as a new network device of the terminal device, and the address of the terminal device uses the address bound to the new network device; and the 4G DTU of the network interface is similar to the telecommunications ADSL Internet access, and generally requires equipment to complete A dialing action.
