Application of TD-2000S in Industrial Ethernet Many existing devices with serial management functions cannot perform networked management and data access. We can use advanced TCP/IP technologies and management methods to transform these devices. This article mainly elaborated on TCP/IP-based serial port data flow, and put forward a system-based total solution for serial port server based on the combination of hardware and software. The overall system, component framework and application architecture of the hardware system are described. With the widespread popularity of the Internet, "letting all devices connect to the Internet" has become the consensus of companies around the world. In order to keep up with the trend of network automation, and not lose the competitive advantage, it is necessary to establish a high-quality networking system for data collection, production monitoring, and instant cost management. The use of TCP/IP-based serial data stream transmission to control the management of the device hardware, without investing a lot of manpower and material resources to manage, replace or upgrade. TD-2000S is an external RS-485/422 to TCP/IP converter (also known as serial server, serial network server, RS-485 network card, RS-485 to network). Shenzhen Tiandi Huajie Technology Co., Ltd. is professionally designed to solve the fast networking of RS-485/422 serial devices. The TD-2000S can use three operating modes: 1. TCP server mode. 2. TCP client mode. 3. Automatic mode. Provide up to 10M network connection, down to provide a RS232 serial port, the parameters can be set through the browser. The TD-2000S supports point-to-point, point-to-multipoint connections and broadcast or multicast support. TD-2000S can convert RS485/422 signals bidirectionally and transparently into network signals, enabling users to connect serial devices to the network without changing the user program without knowing complicated TCP/IP protocols. Valuable time and existing investments. >>Product Features: 1.

The serial port server makes it possible to transmit serial data streams based on TCP/IP. It can connect multiple serial devices and can select and process serial data streams, and convert existing RS 232 interface data into IP ports. Data, then IP-based management, IP-based data access, so that traditional serial data can be sent to popular IP channels, eliminating the need to prematurely eliminate existing equipment, thereby increasing the use of existing equipment. Rate, saving investment, but also simplify the wiring complexity on the basis of the existing network. The serial port server accomplishes the storage control of a connection-oriented RS 232 link and connectionless Ethernet-oriented communication data. The system processes various data, processes the serial port data stream from the serial port device, and performs format conversion. Make it a data frame that can be propagated in Ethernet; judge the data frame from Ethernet and convert it into a serial device that serial data responds to.
