Abstract

The invention discloses a terminal type serial port server with serial port isolation protection. According to the terminal type serial port server, a terminal type serial port module and an Ethernetmodule are both connected to a microcontroller for realizing switching and transmission of a serial port signal and a network signal; the terminal type serial port module is provided with four ports,thereby being connected with a serial port device; and a serial port isolation protection module is further arranged between the terminal type serial port module and the microcontroller, thereby performing isolation protection on serial port data through the serial port isolation protection module. The terminal type serial port server with the serial port isolation protection solves the problem that the isolation protection of a terminal type serial port cannot be realized in the prior art.

Description

technical field [0001] The invention relates to the server field, in particular to a terminal type four serial port server with serial port isolation protection. Background technique [0002] The serial port server provides the serial port to network function, which can convert the RS-232 / 485 / 422 serial port into a TCP / IP network interface, and realize the two-way transparent transmission of data between the RS-232 / 485 / 422 serial port and the TCP / IP network interface. The serial device can immediately have the TCP / IP network interface function, connect to the network for data communication, and greatly expand the communication distance of the serial device. [0003] The current serial port server cannot realize the isolation protection of the terminal type serial port, and it is necessary to design a terminal type four serial port server with serial port isolation protection. Contents of the invention [0004] The object of the present invention is to provide a terminal-t...
