USB-CABLE is a programming cable that uses the USB interface to establish serial connection and convert peripheral port signals. 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), enabling the use of 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 LOGO Controllers, especially in industrial environments with high interference and vulnerable communication ports. Built-in circuit protection ensures safe system operation. USB-LOGO cable eliminates the bulky design of the first-generation adapter and features an integrated high-speed communication chip with a 6-pin square port on the side. It is more portable and offers stable, reliable performance.
