Synchronous Triggering During Stand-Alone Operation - Martin Inground 200 Single Color User Manual

8. Synchronous triggering
during Stand-Alone
operation
Note: This chapter details the rules that are used in Stand-Alone
synchronous triggering. It is not necessary to read this chapter unless
you require help with problem diagnosis or unless you otherwise need
a detailed understanding of the algorithm used for synchronous
triggering.
The rules are as follows:
1. Every fixture can have up to 20 on-board scenes with individual fade and
wait times.
2. Scenes are numbered from 0 to 19.
3. A scene contains a fade-section, followed by a wait-section.
4. When running "synchronous triggering" one master Inground 200 CMY
issues commands to the other slave Inground 200 CMYs 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
