Introduction Usb/ppi+ programming cable simulates usb port as traditional serial port (usually com3), which enables existing programming software(step 7-microwin) to communicate through simulated traditional port and plc devices. The working power supply of this cable is from the usb port and plc programming interface. The two-color led on the converter box indicates datas transceiving status. Usb/ppi+ is optoelectronic isolated, suitable for siemens s7-200 series plc, especially for the strong interfere and easily damaged communication interface industry scene.The safeguard in the circuit guarantees the safely running of the system. Functions Support windows2000/windows xp Support step7 micro/win v3.2 and higher Fully compatible with usb v1.1 and usb cdc v1.1 Power supply by usb bus and plc programming port. Baud rate: 300 bps ~ 1mbps automatically adapt to the standard baud rate. Support uart data format: data bits: 7-8; stop bit: 1, 2; check-bit: odd / even / no parity Support long distance communication up to 2000m(9600 bps).
