How do I connect my MSA Professional/MSA 21 to my computer through a USB Port?

IHT recommends that you purchase a USB to serial adapter cable that converts the 9 pin serial port to a USB connection. The adapter connects between an open USB port on the computer, and your existing serial cable. The adapter is not intended to be connected directly between the computer and MSA unit. IHT recommends the I/O Gear USB to Serial Adapter Model GUC232A as it is the only adapter that is compatible with modern Microsoft Windows Operating Systems.  This can be purchased online at a number of websites and it is NOT typically available at retail stores.
