USB-CABLE is a programming cable that uses the USB interface to establish serial communication and convert peripheral port signals. Programming is conducted through the USB interface connector and serial peripheral signal converter, controlled by computer operations, simulating the computer's USB interface as a traditional serial port (commonly known as COM port), enabling 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. The 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 support safe system operation. This cable improves upon earlier designs by eliminating bulky adapters and incorporates a high-speed communication integrated chip with a built-in 6-pin square port. It offers enhanced portability, stability, and performance.
