You will need a TTL to USB or TTL to RS-232 converter.  The QCX+ has the CAT interface already  built in.  

You can also use an Arduino Uno as a USB to TTL converter. The Arduino program was posted on another thread. Contact me directly if you need help getting the Arduino going — the Arduino  mainline program is only 5 C++ statements.
