USB-CABLE is a programming cable that uses the USB interface to achieve serial connection and peripheral port signal conversion. Programming is provided 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 operating power for the cable is supplied 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. Built-in circuit protection measures ensure safe system operation. USB-LOGO cable eliminates the bulky design of the first-generation adapter and features a new compact design with a high-speed communication integrated chip and a built-in 6-pin square port. It is more portable and offers stable, reliable performance.
