The next rate down is that on every other DMX cycle a new step is output,
and the next speed down from this is that on every third cycle a step is
output. This is how BPM’s of 2400, 1200, 800, 600 etc. are computed.
It also follows that at 2400 there can be no fade time (not that this could be
seen anyway) and any fade at 1200 will only have one step in it. Actually the
full 16 bit fade resolution that the desk produces cannot be output on DMX
until the fade duration is above 27 seconds. This is a limitation of DMX, not
the desk. For 8 bit Channels a fade duration of just over 6 seconds is
required.
8. Preset Focuses
8.1 FOCUSES - some definitions
The word FOCUS tends to crop up a lot in Lighting. For the purposed of this
Manual, have defined the term Focus very clearly to avoid confusion.
“Focus” used to describe the direction in which Fixtures are pointed to
illuminate a space or object will be called a Positional Focus.
“Focus” referring to the sharpness or fuzziness of a projected image will be
called Sharpness.
“Focus” meaning a stored reference for a Fixture Attribute will be called a
Preset Focus.
8.2 What is a Preset Focus?
You can consider Preset Focuses as building blocks which are then used to
build Memories or Chase Steps.
⇒ Preset Focuses can contain any or all of the Attributes of a Fixture.
eg. You can have a Colour Preset Focus that contains all your Fixtures of
whatever flavour in the colour red. This may mean that completely different
values have been stored for your colour changers than for your Intellabeams,
but the result is that you can Select your entire rig of Intelligent Fixtures,
recall this Preset Focus and they will all go red.
When you use a Preset Focus to build a cue, you store a reference to the
Preset Focus, not the absolute Channel levels the Fixture is currently
outputting. The Fixture retrieves the values from the Preset Focus.
Therefore you can change a Preset Focus and have the revised information
replayed in Memories and Chases that use it.
This is very handy!!
eg. If you are touring a show, the truss height and position relative to the
stage may be very different from one day to another. You can store
Positional Preset Focuses to enable you to light the same stage positions
every day without having to edit every cue. Checking and setting Preset
Focuses is far easier than editing each Memory.
