Synchronizing scene changes for multiple Exterior
200s
In situations where you are running multiple fixtures on a data link it is
possible to synchronize scene changes (for fixtures that support this
functionality - see “Introduction” on page 6). Read this section if this applies
in your case.
One controlling fixture triggers simultaneous program start and scene
changes in the other fixtures. Each fixture stores its own program, and the
controlling fixture triggers simultaneous program start and scene changes,
in a cycle, based on its own program.
Each fixture will run its program repeatedly, changing scene when prompted
to by the controlling fixture, or until the controlling fixture finishes its own
program and signals that all fixtures should start from the first scene once
again.
It is important to note that each individual fixture must be programmed with
a show and that the only commands that are passed are scene change
commands. No data about the look of the scene is passed between fixtures.
Automatically triggering stand-alone operation
Stand-alone operation can be set for one or two periods during a 24 hour
period, or for a light level.
Setting a light-level trigger
The option Lightlevel sensor trigger must be set to On .
Stand-alone operation can be set for a specific light level using the Trigger
level spin button, or captured using the built-in light sensor (press Capture
current sensor value to do this). If the light levels fall below the specified
level then operation starts.
If both the timer and the light-level trigger are used, operation starts
whenever it is darker than the light-level setting, and within the times set.
To avoid false triggering by sudden light changes, for example from
automobile headlights, the light level must remain above or below the trigger
threshold for 5 minutes.
Setting a timer trigger
Stand-alone operation can be set for one, or two, periods, during a 24 hour
period, using the built-in clock.
