     This product is fully designed according to industrial standards, 1.The CUP chip adopts the British original FT232RL chip, which has strong compatibility and the communication speed can reach 3M;2. The RS422/RS485 interface chip chooses TI original industrial-grade chip VP3085, the communication distance can reach 1.2KM, and has anti-interference performance in the industrial field; 3. The RS422/RS485 output interface uses high-speed optocoupler for 1500V photoelectric isolation and 600W lightning protection Protection, which can effectively prevent damage to the computer from static electricity, lightning strikes, surges and ground potential differences from the RS422/RS485 bus; 4.RS232 interface adopts high-speed optocoupler for 1500V photoelectric isolation, and adopts DC-DC power module to convert +5V power of USB port into ±12V power supply to supply power to RS232 port, the port voltage is ±12V, RS232 interface chip The serial port chip GD75232 dedicated to the computer motherboard is used, which has very good drive capability.The operation and electrical performance are exactly the same as the RS232 serial port of the desktop computer, and it can directly perform hardware I/O operations. For application programmers, it is like accessing a physical RS232 port. It supports most of the traditional PLC programming cables, and can be connected to various traditional RS232 interface programming cables to communicate with the PLC. As long as it is a programming cable and equipment supported by the computer serial port, this converter supports it.

  RS232 interface pins are arranged as follows:

             & nbsp;                 1----------DCD(input)
            & nbsp;                  2----------RX(receive)
            & nbsp;                  3----------TX(send)
            & nbsp;                  4----------DTR(output)
            & nbsp;                  5----------GND2
            & nbsp;                  6----------DSR(input)
            & nbsp;                  7-----------RTS(output)
            & nbsp;                  8----------CTS(input)
            & nbsp;                  9----------RI(input)

 RS422/RS485 terminals are arranged as follows:（Product label marked）

            & nbsp;                1----------T+(A) RS422 sending positive end/RS485 D+(A)
            & nbsp;                2----------T-(B) RS422 sending negative terminal/RS485 D-(B)
            & nbsp;                3----------R+    RS422 receiving positive end
            & nbsp;                4----------R-    RS422 receiving negative terminal
            & nbsp;                5----------GND2
