Zone types and patching
When a zone is patched and its type is changed, the change is allowed only if the new type 'fits' in the
patch for the original type. As when patching DMX channels, the new type is allowed to patch over
not-patched and single-patched DMX channels. If many zone type changes are to be made after
patching has been done, it may be easier to first clear the patch, then change the zone types and re-
patch them.
2.4.2 Zones table
A zone is shown for each zone in the area. The number of zones in an area is set in the Area table.
•
zone number: The zone number in this area.
•
zone name: 1 to 7 characters.
• zone type: see section 2.4.1
•
patched to DMX: this is first DMX channel that a zone is patched to, if it is patched at all. This
is shown for convenience – the patch cannot be changed here. Change patch information in the
DMX patch table.
•
master enabled: Determines if a zone's intensity is affected by changes from the master
up/down buttons. Master up/down changes only affect intensity, of white lights and color
lights. Colors will be brighter or dimmer but the hue will not change. By default, all zones
controlling intensity are master-enabled. Mastering should be disabled for zones controlling
things not related to intensity (e.g., strobe, effects) or whenever any light needs to be
independent from master up/down changes.
• high trim and low trim: 'Trim' refers to minimum and maximum non-zero output intensity
levels for a zone. These levels correspond to the low and high ends of the zone's slider. For
example, if the high trim is set for 90%, when the zone's level is set to 100% it will actually be
outputting at 90%. The bottom of the slider (the solid gray textured area) will always be the
'off' setting, the low end trim begins just above 'off'. 'Trim' only affects intensity, of white
lights and color lights. A trimmed color light will not change hue, only intensity.
• emerg: If checked, the zone will be at 100% when Emergency is activated. If unchecked, the
zone will not be affected by Emergency.
2.4.3 DMX Layout table
DMX parameters should be set up initially, before DMX channels are patched. Read about zone types
(section 2.4.1) to determine how many DMX channels you will need.
•
DMX channels: the number of DMX channels for this area.
•
first DMX channel: the first DMX channel that this area can assign a zone to. Zones can only
be patched to DMX channels between the first and last, inclusive.
•
last DMX channel: shown only for convenience, determined by the number of DMX channels
and the first DMX channel.
The first and last DMX channels define the range of channels that this area will output DMX to.
Patched channels inside this range are output according to the zones they are patched to. Not-patched
channels inside the range output zero.
