USB-CABLE is a programming cable that uses the USB interface to achieve serial connection and signal conversion for peripheral ports. Cable programming is provided through the USB interface connector and serial peripherals signal converter, under computer control, simulating the computer's USB interface to serial port (commonly known as COM port), enabling the use of current programming software, communication software, and monitoring software. The working power of the cable comes from the USB port and programming port of the LOGO controller. USB-LOGO CABLE is photoelectric isolated, suitable for LOGO controllers, especially in industrial environments with high interference and risk of communication port damage. Various protection measures in the circuit ensure safe system operation. USB-LOGO cable eliminates the bulky design of the first-generation adapter and features a new design with a high-speed communication integrated chip and built-in 6-pin square port. It is more portable and offers more stable functionality.
