USB-CABLE is a programming cable that uses the USB interface to establish a 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 to serial port (commonly known as RS232). This allows compatibility with current programming software, communication software, 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, making it suitable for use with LOGO Controllers, especially in industrial environments with high interference or risk of communication port damage. Built-in circuit protection ensures safe system operation. This cable replaces the bulkier first-generation adapter design, featuring a new compact form with a high-speed communication integrated chip and a built-in 6-pin square port. It offers improved portability and enhanced stability.
