Connect any number of serial devices that do not have a built-in network port via TCP/IP Ethernet.
In the traditional security field, machine room monitoring field, industrial control field, medical equipment field, intelligent building field, there are thousands of sensors, PLCs, controllers, monitors, card readers and other RS-232/485/422 serial devices, are through the RS-232 serial communication or RS-485/42 bus communication and PC for data communication, data exchange and data management. data communication, data exchange and data management. With the development of social needs, thus requiring a larger system, a more stable system, a system with greater data flow. So that the existing RS-232 serial communication, RS-485/422 bus communication can not meet the needs of society. With the rapid popularization of TCP/IP network, thus making the TCP/IP network has been greatly enriched, TCP/IP network has been extended to all corners of society. Compared with RS-32 serial communication and RS-485 bus communication, TCP/IP network has a long communication distance, as long as the connection to the Internet, the communication distance can be extended indefinitely. And RS-232 serial communication distance is only 15M, and RS-485 communication distance is only 1200M (can be extended through the 485 repeater communication distance, but up to 6000M, but also depending on the external environment).TCP / IP network communication quality is stable, because TCP / IP network is based on the design of complex environments, with automatic error correction, so the communication quality is very stable, independent of the external environment. The communication quality is very stable and not disturbed by the external environment. On the other hand, RS-232 serial port communication, RS-485 bus communication is less resistant to interference and prone to errors. With the development of TCP / IP network, its communication flow continues to improve, now TCP / IP network 100M has become the standard configuration, and 1000M data interface is also being popularized. The RS-232 serial communication, RS-485 bus communication rate can only be up to a maximum of 100K or so, and with the rate of increase, its stability, communication distance will be inversely proportional to the corresponding changes.
