USB-CABLE is a programming cable that uses the USB interface to enable serial connection and signal conversion for peripheral ports. 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 and risk of communication port damage. The circuit includes various protection measures to ensure safe system operation. USB-LOGO cable eliminates the bulky design of the first-generation adapter and features a new design with a built-in high-speed communication micro-integrated chip and a 6-pin square port side. It is more portable and offers more stable and powerful performance.
