Digital Join Numbers
Signals on the left represent data being sent to the Scheduler (input to the
Scheduler); signals on the right represent data coming from the Scheduler
(output from the Scheduler) .
dig o21 – o27
SourceA – SourceF and SourceLocal: The rising edge of the signal indicates
to the Scheduler that the specified source device is being requested for use.
(The Scheduler then checks the validity of the request.)
dig i21 – i27
Feedback for SourceA – SourceF and SourceLocal: If the specified request is
valid, the Scheduler provides feedback that latches high for the duration of
the event, then clears when the event is over.
Note: The switching logic for a local source must be included in the
Classroom program. For example, a "Main" feed from the head end might go
into one input of a TV, while that of the local source would go on another
input of the TV. If any of the SourceA – SourceF feedback signals goes high,
the room's control program should then select the "head end" input; if the
Local Source feedback signal goes high, the local input should be selected.
