This USB adapter cable acts as the administrator key to allow access to certain functions within a Media Controller. This small cable unlocks powerful functions that save time and money. Within administrative mode, users can upload/download new equipment configuration scripts that allow for easy deployment across multiple controllers as room equipment changes. It also allows access to infrared (IR) programming capabilities, making programming via a remote control hassle-free. Firmware updates can also be made across multiple controllers without the need to remove the controller from the wall.
