Presets: Defined vs. Undefined Levels
Understanding the meaning of the terms "defined" and "undefined", as used in the context of levels in a
Radia lighting system, is necessary for properly setting up presets for multiple lighting zones. Each
dimmer on the Radia has a TRUE/FALSE status associated with it that is referred to as "defined". The
state of the defined status is used when saving presets so that the Radia knows which dimmers are to be
affected when the preset is recalled. Upon power-up, all the dimmers are in the undefined state. As soon
as any of the dimmers changes state (i.e. the level changes), the dimmer automatically becomes defined.
Upon recording a preset, the Radia will save all of the dimmer levels that are defined at that time and
only affect those when the preset is recalled.
For example, if all the dimmers are undefined and dimmers 1 and 3 get their levels changed, the Radia
will save the levels of 1 and 3 only when told to record preset 7. When preset 7 is recalled, only dimmers
1 and 3 will be adjusted. The other dimmers (2, 4, 5 and 6) are said to be undefined for that preset.
Preset Status
Channels 1-128 reflect the current status of active presets. A preset is "active" for as long as its
associated dimmers (circuits) remain at the levels associated with the preset. For example, assume the
following presets exist in the Radia:
Preset #
