How to Switch the RS485 Interface of Multiple Serial Device Server

How to Switch the RS485 Interface of Multiple Serial Device Server

Most of the projects that use Ethernet for networking today use RS232 or RS485 interface, and the usage share of the RS422 interface is relatively small. However, in order to meet the needs of the public, the serial port is usually made into a mode that can switch interfaces freely. For example, USR eight serial device server USR-N668.

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.
