USB-CABLE is a programming cable that uses the USB interface to achieve serial connection and peripheral port signal conversion. Cable programming is provided through the USB interface connector and serial peripherals signal converter, under computer control, simulating the computer's USB interface to serial communication (commonly known as COM port), enabling the use of current programming software, communication software, and monitoring software. The working power of 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 LOGO Controllers, especially in industrial environments with high interference and vulnerable communication ports. Built-in circuit protection measures ensure safe system operation. The 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 performance.
