Ethernet to RS485 Converter and 4G LTE modem (data transfer unit) are both devices for serial communication, but there are some differences:
Function: Ethernet to RS485 Converter is a device that can connect RS485 serial devices to the network, and remotely manage and control these devices through the network to achieve industrial control and monitoring functions. The 4G LTE modem is a communication device whose main function is to transmit and monitor data between devices in different locations.
Communication protocol: Ethernet to RS485 Converter usually supports multiple communication protocols, such as TCP/IP, UDP, HTTP, FTP, etc., while 4G LTE modem usually supports Modbus, Profibus, CAN, etc.
Scope of application: Ethernet to RS485 Converter is mainly used in the field of industrial automation to manage and control the integration of multiple serial devices, while 4G LTE modem is mainly used in remote data transmission, such as machine room monitoring, water, electricity and gas monitoring, smart home and other fields.
When to select Ethernet to RS485 Converter and when to select 4G LTE modem?
RS485 serial devices need to be remotely managed and controlled, such as industrial control and monitoring, production automation and other scenarios;
Integration and debugging of serial devices are required, such as centralized management and analysis of data from multiple serial devices;
Data acquisition, transmission and monitoring of serial devices are needed without debugging and integration of multiple devices.
It is necessary to remotely transmit equipment data at different locations, such as computer room monitoring, water, electricity and gas monitoring, etc.
It is necessary to realize data exchange and sharing through the network, such as smart home, intelligent transportation and other scenarios.
Data transmission and control need to be realized across different network environments, such as mobile networks, wide area networks, etc.
In a word, the choice of Ethernet to RS485 Converter or 4G LTE modem should be judged according to the specific application scenarios and requirements, so as to select a more suitable device.
