What is Serial Device Server?

What is Serial Device Server?

Serial device server provides serial port to network function, which can convert the RS-232/485/422 serial port into TCP/IP network interface, realizing bidirectional transparent transmission of data between RS-232/485/422 serial port and TCP/IP network interface. It enables the serial device to immediately have the TCP/IP network interface function, connect the network for data communication, and greatly expand the communication distance of the serial device.
