What Are the Transparent Transmission Characteristics of Serial to Ethernet Device Server?

What is a serial to ethernet device server?

The serial to ethernet device server provides the function of converting serial port to network port, which can convert RS232/485/422 serial port to TCP/IP network interface, and maintain bidirectional and transparent transmission of statistical data between RS232/485/422 serial port and TCP/IP network interface. The serial port equipment immediately has the function of a TCP/IP network interface, the network connection carries out data communication, and the communication distance of the serial port equipment is greatly enlarged.

How to make serial to ethernet device servers in the automation technology industry have the ability to connect to the network and connect to the network immediately?

The serial port connection network server allows the traditional RS232/422/485 machine equipment to be immediately connected to the network, and the hardware configuration of the machine equipment which operates the management method through the TCP/IP serial port data flow analysis transmission is a highway bridge dedicated to the connection of the serial port to Ethernet interface design scheme. The serial port device is connected to the network server just like every CPU, the real-time operating system of the microcomputer, and the TCP/IP protocol, which facilitates the transmission of data between the serial port and the computer device.

You can store, manage and equip remotely controlled machines and equipment all over the world via the Internet. The serial server provides the function of converting the serial port to the Internet. The serial server can convert the RS232/485/422 serial port into the TCP/IP network interface, and maintain the bidirectional and transparent transmission of the statistical data of the RS232/485/422 serial port and the TCP/IP network interface. The serial port equipment immediately has the function of a TCP/IP network interface, the network connection carries out data communication, and the communication distance of the serial port equipment is greatly enlarged.

The maximum transmission distance of the RS485 bus used by the serial device is not more than 1200 meters. In order to further transmit the data of these devices, we need to add a serial server, so that the serial devices immediately have the function of TCP/IP network interface, data communication through the Internet, and any place where there is the Internet can access the data of serial devices.

In practical application, the completion of the serial server is to map the Ethernet interface of TCP/IP protocol to the standard serial port under the Windows operating system. The application can receive and control it like a normal serial port. For example, a general computer has two serial ports COM1 and COM2, and the above serial ports can be mapped to COM3, COM4, COM5, etc. Through the serial server.

RS232 and RS422/485 buses are the most common communication interfaces for connecting these devices. Ethernet/Internet and other network architectures have been widely used in the automation industry, replacing traditional serial communication and becoming the mainstream of automation system communication.

Characteristics of Transparent Transmission of Serial Server

The length and content of the sender's and receiver's data are exactly the same, which is equivalent to an invisible transmission line. Transparent transmission technology is used in many fields such as OTN and PTN. PWE3 is one of the key technologies in T-MPLS networks. PWE3(Pseudo Wire Emulation Edge-to-Edge)A service emulation mechanism intended to provide as little functionality as possible to emulate a circuit as required by a given service. This mechanism requires establishing and maintaining a pseudowire (PW) in a tunnel of a packet-switched network (PSN), encapsulating and transmitting service data or clock synchronization information by using the PW and keeping the attributes and characteristics of the service data or the clock synchronization information as true as possible. For the customer equipment, the PW appears as a link or circuit exclusively used by a specific service, which is called a Virtual Circuit (VC).

Advantages of Transparent Transmission Module

The dynamic frequency hopping technology is adopted, which has strong environmental adaptability and effectively avoids interference; Like SKYLAB's WiFi module and Bluetooth module, both support Uart passthrough. A transparent transmission module is often used in remote meter reading, access control systems, wireless data communication, industrial data acquisition, wireless remote control and telemetry, security system, robot control, and other fields.

The role of two-way transparent transmission

The two-way transparent transmission function means that the Tashi wireless communication module sends and receives data through a transparent transmission channel, which can be transmitted back and forth.

Why do you want to pass it on?

Transparent transmission is generally used to read remote serial port data. In the Internet of Things era, if we want to realize the data transmission of intelligent devices, we need to rely on the power of a wireless transmission module, which can realize that the length and content of the sender and receiver data are exactly the same, without any processing of the data, which is equivalent to a data line or serial port line. It can be widely used in energy and power, automatic meter reading, smart cities, industrial automation, vehicle transportation, environmental monitoring, equipment monitoring, modern agriculture, and many other industries.
