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 working power of the cable is supplied 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 vulnerable communication ports. Comprehensive protection measures in the circuit ensure safe system operation. USB-LOGO cable eliminates the bulky design of the first-generation adapter and features a new design with a built-in high-speed communication micro-integrated chip and a 6-pin square port side. It is more portable and offers more stable and powerful performance.
