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 the use of current programming, communication, 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 and vulnerable communication ports. Built-in circuit protection ensures safe system operation. The USB-LOGO cable features a redesigned compact form with a high-speed communication integrated chip and a 6-pin square port, offering improved portability, stability, and performance.
