If you are programming a group of fixtures
to perform the same scenes with
synchronized master/slave triggering, we
recommend that you:
1. Use MUM to program a show on one
slave fixture
2. Download and save this fixture's
program and settings to your PC using
MUM's Files menu (see Figure 16),
and then
3. Upload the program and settings to
each subsequent fixture that you
connect to.
For a more detailed explanation of
synchronized operation and how
advanced effects can be created by
programming fixtures with a different
number of scenes, see the next section.
Synchronized stand-alone operation: detailed description
Note: This section gives advanced information about stand-alone synchronized operation. You only need
to read it if you require help with problem diagnosis or if you want to program advanced
synchronized light shows.
The principles in stand-alone synchronized operation are as follows:
1. A scene contains a fade section, followed by a wait section
2. Each fixture can be individually programmed with up to 20 scenes, and each scene can have its own
individual fade and wait times.
3. Scenes are numbered from 0 to 19.
4. In synchronized operation, one master fixture issues commands to the other slave fixtures to "go to
scene xx", where xx is the scene number that the master will execute next.
5. If a slave has fewer scenes than the master, it will derive which scene to go to by dividing the number of
the scene it has been commanded to go to (scene 5, for example) by the total number of scenes that the
slave fixture has (4, for example) in whole numbers (no decimal places). In this example 5 divided by 4
results in 1, with 1 remainder. This remainder will be the number of the scene that the slave fixture starts
- scene 1. Generally though, when a Slave fixture reaches its own last scene before the Master fixture, a
"go to scene xx" message will result in the first scene being played.
6. If a slave has more scenes than the master calls, the last scenes in the slave will never be executed, as
is the case with scene S4 in the following example.
F=fade, W=wait
Programmed in Master
Programmed in Slave
Result
7. In synchronized operation, the wait time is determined by the master. Every slave fixture fades and waits
at its own rate and then remains in the "wait" state until it receives a "start scene xx" command from the
master.
8. A slave fixture will not listen for the next message from the master fixture before it has finished its current
scene. This may result in a slave skipping a scene if the slave has a longer scene time than the master.
