You will need an interface from the computer to the control box. One that uses USB from the computer is the

ERC-M http://schmidt-alba.de/eshop/

It is a simple system and interfaces well with SATPC32 or WxTrack

Another is the: http://store.amsat.org/catalog/index.php?cPath=1_25 LVB tracker sold by AMSAT http://store.amsat.org/catalog/index.php?cPath=1_25

If you have radios with CAT interfaces you can use SATPC32 or WxTrack to run the radios and the rotor tracker.

All have their quirks but keep asking on this list and we will try to help.
