red light indicator for cdj 2000 nexus

@Akash > @Daniel is correct; the red jog illumination is to indicate that the player is currently "on air" (live to the master ouptut). To enable this functionality, the players and mixer (DJM-2000nexus, DJM-2000, DJM-900SRT, or DJM-900nexus) must all be linked via ethernet, and the audio channels to which the players are connected must match the player number in the display.
