Serial device server is a communication interface converter for data conversion between RS-232/485/422 and TCP/IP. Provide RS-232/485/422 terminal serial port and TCP/IP network bidirectional transparent transmission of data, provide serial to network function, RS-232/485/422 to network solution. Allow serial devices to instantly connect to the network.
With the widespread use of the Internet, "making all devices connected to the network" has become the consensus of enterprises all over 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 networked system for data collection, production monitoring, and instant cost management. Take the advantage of TCP/IP-based serial data stream transmission to control and manage the device hardware, there is no need to invest a lot of manpower, material resources for management, replacement or upgrade.
Serial device server makes TCP/IP-based serial data stream transmission possible. It can connect multiple serial device servers and can select and process the serial data stream, and convert the data of the existing RS 232 interface into the data of the IP port, then make IP management and IP data access, so that traditional serial data can be sent to the popular IP channel without premature elimination of the original device, so as to improve the utilization rate of the existing equipment and save the investment, and simplify the wiring complexity on the basis of the existing network. The serial device server completes storage control for communication data between connection-oriented RS 232 link and connectionless Ethernet. The system processes various data and the serial data stream from the serial device, and performs format conversion to make it a data frame that can be propagated in the Ethernet; judge data frames from Ethernet and convert into a serial device for serial data delivery response.
