USB-CABLE is a programming cable that uses the USB interface to enable serial connection and peripheral port signal conversion. Cable programming is achieved 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), allowing 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 photoelectrically isolated and suitable for LOGO Controllers, especially in industrial environments with high interference or risk of communication port damage. Built-in circuit protection measures ensure safe system operation. USB-LOGO cable features an updated design that replaces the bulky first-generation adapter, incorporating a high-speed communication integrated chip with a built-in 6-pin square port. It is more portable and offers stable performance.
