Serial device server parses the packets from the TCP/IP protocol into serial data streams; Conversely, the serial data stream can also be converted into a TCP/IP protocol data packet to realize data network transmission.

 

Serial device server can connect multiple serial devices and can select and process the serial data stream, convert existing RS232 interface data to IP port data, this will enable traditional serial data to be sent to popular IP channels, it is not necessary to prematurely eliminate the original CNC system equipment without Ethernet module, so as to improve the utilization rate of existing equipment, save investment and simplify wiring. In the aspect of data processing, the serial server completes storage control of communication data between connection-oriented RS232 link and wireless connection Ethernet. The system processes various data, processes the serial data stream from the serial device, and performs format conversion to make it a data frame that can be transmitted in the Ethernet; Judge the data frame from Ethernet and convert it into a serial data to deliver to the serial device with response. In practical application, what the serial server completes is to map the Ethernet interface of the TCP/IP protocol to a standard serial port under the Windows operating system, the application can send and receive and control like a normal serial port, for example, a general computer has two serial ports COM1 and COM2, and the serial port can be mapped to COM3, COM4, COM5 through the serial port server.
 

Serial network server products provide a solution for accessing industrial equipment directly over the network. Therefore, traditional serial devices can be converted to Ethernet devices that can be monitored and controlled from a local area network or even the Internet.
