- AVDECC Entity Controller
The AVDECC Entity Controller can be started from the *Terminal*.
``` $ avbutil avbutil 740.1
avbutil> controller avbutil> ```
Once the controller is started, the AVDECC Entity Controller window should open. This provides general information about the available AVB streams.

To see what streams are patched where, open the AVDECC Connection Matrix from the Window menu (or by typing Cmnd-4). **This tool can be used to patch Talkers and Listeners with each other.** Talkers are listed across the top, and Listeners across the left. In the image below, the one patched connection [X] below reflects that the Avid E3 Engine output stream for channels 1-8 is patched to a MOTU Stage-B16 input stream.
