Why do 4G industrial routers lose packets
Industrial 4g router that is 4G modem performs data transmission via networking. However, during the data transmission process, if the network is unstable, the packets will lose. The most common reasons are the following four points.
Is serial device server a simple server?
Serial device server is basically a server that converts any serial device into an Ethernet-enabled device that can be used in the network. For example, traditionally, old non-network printers that only work when connected to a COM port on a computer can be converted to networking printers, which are controlled from anywhere by connecting it to a serial server, and the serial server is connected to the network through an Ethernet cable.
Common communication problems with serial device servers used in data loggers
The data logger can record available data, but if you can't retrieve it, then the data won't fully play its role. In order to ensure the data can be retrieved successfully, it is necessary to resolve issues that may arise when communicating from the serial device server to the data logger. The following text summarizes six most common problems and explains how to solve these problems easily.
What is the international name of serial device server?
Serial device server, also known as serial line end server or port redirector internationally, is a device that transfers data between computer serial port (COM port) and Ethernet local area network (LAN). This allows Ethernet to be used to replace serial port devices, reducing workstation clutter to the largest extent, and allows serial devices to be placed far from the computers that use them.
Detailed analysis of the difference between 4G routers and 4G Modems
4G industrial wireless routers and 4G Modems, both two are used for wireless network data transparent transmission of industrial equipment. However, both have obvious differences, the differences between the two are distinguished mainly from the three aspects of appearance interface, usage method and application environment.
What is industrial RTU?
RTU is the basic composition unit of the SCADA system. RTU is an electronic device installed at a remote site to monitor, measure, and collect sensors and equipment installed at remote sites, responsible for monitoring and controlling live signals and industrial equipment. RTU converts the measured status or signal into a data format that can be sent over the communication media, it also converts the data that is sent from the central computer into commands to realize functional control of the device.
