The RC4Magic USB XStick configuration dongle is a simple wireless interface device for connecting a PC to an RC4Magic Series 2 or Series 3 system for the 2.4GHz system.
Together with RC4 Commander Configuration Software, a wide array of features and functions are easily configured with the ease of a PC-based graphical user interface.
RC4 Commander Configuration Software does not require this dongle — an RC4Magic Series 3, together with an RC4 CodeLoader Cable, provides a Dongle Mode that functions exactly like this dedicated USB device. It is up to you which connection hardware you prefer to use. The RC4 USB XStick does allow for easier portability. By getting power directly from your computer there is no need to be tied to a wall outlet.
