USB-CABLE is a programming cable that uses the USB interface to establish serial communication and convert peripheral port signals. The cable enables programming via the USB interface connector and a serial peripherals signal converter, under computer control, simulating the computer’s USB-to-serial (commonly referred to as COM port) functionality. This allows compatibility with standard programming, communication, and monitoring software. Power is supplied through the USB port and the controller’s programming port. The USB-CABLE features optical isolation, making it suitable for use with controllers—especially in industrial environments with high electromagnetic interference or vulnerable communication ports. Built-in circuit protection ensures safe and reliable system operation. This updated design eliminates the bulky first-generation adapter, incorporating a high-speed communication integrated chip and a compact 6-pin square connector. It offers improved portability and enhanced functional stability.
