USB-CABLE is a programming cable that uses the USB interface to enable serial connection and peripheral port signal conversion. Programming is conducted through the USB interface connector and serial peripherals signal converter, under computer control, simulating the computer's USB interface as a traditional serial port (commonly known as COM port), allowing compatibility with current programming software, communication software, and monitoring software. The cable is powered by the USB port and the programming port of the LOGO controller. USB-LOGO CABLE features photoelectric isolation and is suitable for use with LOGO Controllers, especially in industrial environments with high interference or risk of communication port damage. Built-in circuit protection measures ensure safe system operation. The USB-LOGO cable eliminates the bulky design of the first-generation adapter and features a new compact design with a built-in high-speed communication micro-integrated chip and a 6-pin square port. It is more portable and offers stable, reliable performance.
