Abstract

The invention discloses a terminal type two-serial-port server with serial port isolation protection. The server comprises a terminal type serial port module, a microcontroller and an Ethernet module,wherein the terminal type serial port module and the Ethernet module are both connected to the microcontroller to realize the conversion and the transmission of a serial port signal and a network signal; the terminal type serial port module also comprises a terminal, a contact sensor, a power circuit and a ring light; a terminal is arranged in the serial port interface of the microcontroller; thecontact sensor is arranged in the terminal; the ring light is arranged around the terminal; and under a situation that the contact sensor induces and matches a contact head, the contact sensor outputs a driving level to the power circuit to enable the power circuit and the ring light to form a closed loop. By use of the terminal type two-serial-port server with serial port isolation protection, the problem in the prior art that whether a connection wire is connected or not can not be clearly displayed is solved, and the display of connection wire connection is realized.

Description

technical field [0001] The invention relates to the server field, in particular to a terminal type two 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 server cannot clearly display whether the connection is connected. Based on this, it is necessary to design a server that can clearly display whether the connection is connected. Contents of the invention [0004] The purpose of the present invention is to provide a terminal-type two-serial-p...
