Your PV has an ethernet port used to connect to your PLC, SLC or what ever brand you have. It also has a RS232 port used to connect a printer or upload/download your PV program. If the RS232 port has not been configured as a printer port, then a staright thru cable between it and your PC/Laptop will work. Use the DF1 driver in RSLinx for this connection. If your laptop does not have a serial port the a USB to serial adapter will work. The best USB to serial adapter is a "Keyspan" brand.
Your 1747-UIC is a USB to DH485 converter, it will not work with your PV.
