USB-CABLE is a programming cable which uses the USB interface to achieve the serial connection and the conversion of peripheral port signal. Cable programming is provided through the USB interface connector and serial peripherals signal converter programming, under the control of computer operation, simulating the computer's USB interface to traditional serial (commonly known as COM port), thus using the current programming software, communication software and monitoring software. The work power of the cable comes from USB port and programming port of LOGO controller. USB-LOGO CABLE is photoelectric isolated, can be applied to LOGO Controller, especially the industrial fields with greater interference and easily damaged communication port. Various kinds of protection measures in the circuit allow the safe operation of the system. USB-LOGO cable removes the 1st generation heavy adapter appearance and applies the new design with high-speed communication - integrated chip built-in 6pin square shape port side. It is more portable and functions more stable and powerful. Purpose: Suitable for LOGO Series PLC programming cable Length: 3 meters Please check the interface before you order the product: PC-CABLE: PC side is 9pin female plug RS232 port, PLC side 6pin square shape USB-CABLE: USB port connects PC, PLC side 6pin square shape Colour: black Material: PVC + copper wire Package Contents: 1 x PLC programming cable Only the above package content, other products are not included.
