USB-CABLE is a programming cable that uses the USB interface to enable serial connection and peripheral port signal conversion. Cable programming is achieved 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 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 is photoelectric isolated, suitable for LOGO Controllers, especially in industrial environments with high interference and risk of communication port damage. Built-in circuit protection measures ensure safe system operation. USB-LOGO cable features an upgraded design, replacing the bulky first-generation adapter with a compact form factor and integrated high-speed communication microchip, featuring a 6-pin square port. It is more portable and offers stable, reliable performance.
