Description
Playing
9,28
Closed when the unit is playing.
Fault
10,29
Closed when the unit detects a fault
condition.
You can also control these outputs with serial “Relay” commands. One practical
application of this is to embed the “Relay” commands in a playlist along with “Play
Sound” commands. This way you can close or open a relay when a sound plays or
stops.
Please refer to the Miscellaneous Commands under Advanced Serial Protocol for
details on how the “Relay” command works, and to the Playlist Section for an
example playlist which demonstrates the use of the “Relay” command.
