USB-CABLE is a programming cable that uses the USB interface to establish a serial connection and convert peripheral port signals. Cable programming is achieved through the USB interface connector and a serial peripherals signal converter, under computer control, simulating the computer’s USB interface to serial port (commonly known as COM port), enabling compatibility with current programming, communication, and monitoring software. The cable draws power from the USB port and the LOGO controller’s programming port. USB-LOGO CABLE features optical isolation, making it suitable Compatible with LOGO controllers—especially in industrial environments with high electromagnetic interference and vulnerable communication ports. Comprehensive circuit protection ensures safe system operation. The USB-LOGO cable replaces the bulky first-generation adapter with a modern design featuring a high-speed communication integrated chip and a built-in 6-pin square port. It offers improved portability and enhanced functional stability.
