634 USB, What else do I need?

I'm going to get that 634USB device, but from the pictures it seems that there only are an RS232 connector at the back of the print. How do I get this thing connected to my USB port?

The 634 USB is a converted Serial Module. The USB model has an added-on riser card attached to the back that will provide support for your USB connection. For all intents and purposes, the Serial Port on the USB model is useless. Make sure while ordering your USB model that you also order up your cable too.
