Hi Mario,

As I understand it the driver for both the dongle and the TX modules are part of the Giga-control package, and is down loaded to your PC when you install Giga-control. Attached is the manual on how to install the drivers. The instruction for installing the driver say to browse in the directory of Giga-control, but they do not name the file. If you have Giga-control installed, you should have the drivers. I managed to install them using this manual.

Hope this helps.
