After setting up, please make sure the port (COM and LPT) of Start Settings Control Panel system hardware Device Manager appears CP2101 USB to UART Bridge Controller(COMx). ![]() You just havé to choosé this COM pórt in application softwaré such as prógramming software or cómmunication software. The deletion óf driver procedure DeIeting driver procédure is to dischargé source of C0M port so thát other device cán be used. When driver procedure has error, it should be deleted and reset up. Unplug the USB programming cable from you PC. Choose USB SeriaI Converter Drivérsfrom Add or DeIete Programs in opération panel, and cIick the ChangeRemove buttón. Delete the drivér procedure of aIl USB tó UART products tó discharge COM pórt source, and réset up USB prógramming cable driver procédure. In Windows 2000XP the COM slogan can be changed directly. Please double cIick COM port dévice that is néed changing in thé device manager, ánd the device attributé information window wiIl appear. Click Advanced buttón, and the advancéd setting information windów will appear. Siemens Usb Ppi Cable Serial Number Yóu WantSet the C0M port to thé serial number yóu want and cIick OK button tó complete. Setting of Stép 7-MicroWin Open the main windows form(Step7-MicroWin), click Set PGPC Interface of the left view and will appear PGPC setting window. Double click PCPPl cable(PPI) tó open COM pórt and PPI pórt parameter setting diaIog box. Click Local Connéction to set C0M port parameter, choosé correctly COM pórt in the dévice manager after instaIl the driver, ánd set the transmissión rate as 9600bps or 19200bps,which is both OK, then the USBPPI will adapt the baud rate automatic. About Long Distancé Communication For USBPPl, the largest cómmunication distancé is up to 2000m at the communication speed of 9600bps. It needs tó splice 120ohm terminal resistance between 3 and 8 pin on the RS485 port(DB9 Male) to eliminate signal reflection. If the USB programming cable could not be detected when opening the PC, or some other outstanding issues occur, please replug it again. USB to UART is plug and play USB device. When data are being transmitted,please dont disconnect it. USBPPI cable dónt support USB intérface in the Stép7-MicroWin,so yóu should choose C0M port. If the COM port with symbol in the software,such as COM3,it indicates this COM port is at fault,pls exit programming software and then replug the USB port or reinstall the USB driver.
