Activate/Deactivate a Playlist

Playlists may be activated onsite by throwing a user-installed switch, wired to one of the control inputs on the rear of the NX8R. Any of NX8R's eight control inputs as well as its playlist contents may be virtually activated using a remote phone or the control phone. This activation is virtual in that there is no physical closure on the control input's contact. Using the following command causes the playlist associated with the activation control input to run until deactivated. (In this example, use Control Input 5 via the control phone ore remote phone to cause Playlist 5 and its content to run).
  1. Press *92# to begin the "set a virtual control input" command.
  2. Press 5# to select Control Input 5.
  3. Press 3# to activate Control Input 5.
In the following example we will deactivate Control Input 5 to cause the playlist to stop running and the next lowest activated (physical or virtual) control input and its associated playlist to run:
  1. Press *92# to begin the "set a virtual control input" command.
  2. Press 5# to select Control Input 5.
