The global patch dialog
Click Previous or Next to locate the previous or next channel cintaining any patch settings. To clear
all settings for one or more output channels, highlight the relevant lines and click Clear. To clear all
patch settings, select New Global Patch from the File Menu. To 'synchronize' all settings for
multiple channels, highlight the relevant lines, change settings if necessary, then click <-Set Values.
Setting the minimum and maximum output value of a DMX channel.
To set the minimum and/or maximum value of one or more channels, highlight the corresponding lines
in the patch list. Set the minimum and or maximum values in the Min and Max fields respectively.
Alternatively, highlight, right-click and select Clear -> Min or Clear -> Max from the popup menu. A
minimum value of 0 and the minimum value of 255 are default and will not be displayed in the patch-
list. When the patch is applied, minimum and maximum limits are applied to the DMX output values
before the values are transmitted to the fixtures and do not affect the programmed data. For example,
if an output channel is programmed to a value of 5 and a minimum value of 10 is set, the DMX output
will never go below 10. If the minimum value is removed or lowered below 5, the channel will output 5
as programmed.
Tip:Applying a minimum output level for par cans for similar fixtures using halogen lamps can
drastically shorten the time it takes the lamp to 'go on' (pre-heat).
Inverting the DMX output value
Setting the invert flag inverts the output value of the channel, e.g. a programmed value of 0 is inverted
to the value of 255, or a value of 100 is output as 155. The operation performed is analog to inverting
the output of a fader on a normal console so that the fader has maximum output when all down and
minimum output when pushed to the top. The inverting of the value is performed before any min/max
constraints are applied so the inverted output values will still be inside the min/max interval.
Modifying the source of output values
Modifying the DMX Output source
Changing the DMX output source means changing the source of the DMX output value transmitted to
the channel. The source of the DMX output value can be another DMX output channel or a DMX input
channel. Patching several output channels to the same source may be useful when there is a need to
control multiple channels from one source (e.g. a generic DMX fixture profile fader) or, using DMX in,
from a console fader. Often, when using generic DMX fixtures such as Par 64 or pin spots, it is
practical to control the fixtures in groups, even if each fixture has an individual DMX address on the
dimmer rack (see HTP groups below). Unless the dimmer/switch packs supplying the fixtures has the
capability of patching and it is necessary to allocate an individual channel to each of the fixtures
(which may use up a lot of generic controls/channels). Using the patch tool it is possible to reduce
the number of 'control channels' needed to control the number of groups that are used.
Setting the source to a DMX output channel
To patch one or more channels so that they take their output value from another output channel,
