USB-CABLE is a programming cable which uses the USB interface to achieve serial connection and conversion of peripheral port signals. Cable programming is provided through the USB interface connector and serial peripheral signal converter programming. Under the control of computer operation, it simulates the computer's USB interface to a traditional serial port, commonly known as COM port, thus supporting use with current programming software, communication software and monitoring software. The operating power of the cable comes from the USB port and the programming port of the LOGO controller. USB-LOGO CABLE is photoelectrically isolated, and can be applied to industrial fields with greater interference that easily affect communication ports. The circuit is equipped with various protection measures. USB-LOGO cable eliminates the bulky adapter appearance of the 1st generation model and adopts a design with a high-speed communication micro-integrated chip built into the 6pin square port side.
