The invention relates to the field of serial servers, and discloses a serial server with optical fiber 32-port isolation. The serial server comprises that an Ethernet MAC (Media Access Controller) isprovided with an optical fiber interface, wherein two ends of a network transformer are connected with multiple pieces of network equipment to isolate levels among the network equipment; the EthernetMAC is connected to the network transformer to control the work of the network transformer; an ARM9 main chip is configured to execute signal conversion between an Ethernet protocol and a serial portprotocol to convert a serial signal from a serial port circuit module into a network signal or convert a network signal from the Ethernet MAC into the serial signal; a serial circuit module comprisesa serial expansion circuit and a serial interface circuit, wherein the serial expansion circuit expands the serial interface of a microprocessor into 32 ports, and the serial expansion circuit is configured to be connected with the serial interface circuit. By use of the serial server with optical fiber 32-port isolation, optical fiber and 32-port isolation of the serial server can be realized.
Description
technical field [0001] The invention relates to the field of serial port servers, in particular to a 32-port isolation serial port server with optical fibers. 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 serial port server at the present stage cannot perform optical fiber transmission, let alone serial port isolation. It is urgent to design a 32-port isolated serial port server with optical fiber. Contents of the invention [0004] The purpose of the present invention is to provide a 32-port isolated serial p...
