USB-CABLE is a programming cable that uses the USB interface to establish a serial connection and convert peripheral port signals. Programming is achieved through the USB interface connector and serial peripherals signal converter, controlled by computer operations, simulating the computer's USB interface as a traditional serial port (commonly known as COM port). This allows 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 and suitable for use with LOGO Controllers, especially in industrial environments with high interference or where communication ports are prone to damage. Built-in circuit protection measures ensure safe system operation. The USB-LOGO cable features an improved design over the first-generation adapter, incorporating a high-speed communication micro-integrated chip and a 6-pin square-shaped port. It is more compact, portable, and offers stable and reliable performance.
