This USB adapter cable acts as the administrator key to allow access to certain functions within the Trulink 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.
