USB-CABLE is a programming cable that uses the USB interface to establish serial connection and convert peripheral port signals. Programming is conducted 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), enabling compatibility with current programming, communication, and monitoring software. The cable is powered by the USB port and the programming port of the LOGO controller. The USB-LOGO CABLE features photoelectric isolation and is suitable for use with LOGO Controllers, especially in industrial environments with high interference or unstable communication conditions. Built-in circuit protection ensures safe system operation. This cable eliminates the bulky design of first-generation adapters and incorporates a compact, high-speed communication micro-integrated chip with a built-in 6-pin square port. It offers improved portability, stability, and performance.
