Dmx And Real Time Events; Control Trigger Rules - Christie M Series User Manual

Appendix C: DMX / ArtNet
C.1 DMX and Real Time Events
There are Real Time Events trigger types that allow RTEs to be triggered via DMX channels. An RTE event
may be linked to DMX channels 55-64. These controls have the same behavior as toggle/checkbox controls,
with 25%-75% hysteresis built in. When a control is moved above 75%, the linked RTE will be triggered.
When any of the RTE linked controls are moved below 25%, any RTE that is currently running will be told to
stop (user abort), regardless of which RTE or where it was executed from.
C.1.1 Control Trigger Rules
1. Projector control values are not mapped to slider values in a 1-to-1 mapping (where possible). i.e. when a
control value has a range from 0 to 1, it is not expected that the slider will only be moved from 0 to 1. A
greater range of movement is allowed for on the slider.
2. Toggle Controls - Due to possible "dithering" between two values, the DMX control values accommodate
a hysteresis (i.e. must move slider above 75% to turn on and below 25% to turn off).
3. Slider Lock - This is used to lock out all controls if it is in the enabled state. If the slider lock is unlocked,
all channel changes that have occurred since the lock was enabled will then be applied.
4. Apply All Channels will force the set of all values on the board in an effort to synchronize control values
with the slider values currently set. (subject to slider lock restrictions above)
5. Lens Controls - Values are split between 2 channels to give the full 4100 (or 2100) values of resolution.
The coarse control represents the first 8 bits and the fine control the remaining 4 bits.
6. Power Control has a built-in timer: the control must remain in the "on" range (75%-100%) or in the "off"
range (0%-25%) for 5 seconds before it takes effect.
7. Lamp Operation only allows for the selection of 2 items, either Auto-Select Single lamp or Dual lamp.
8. Static Lists Channel and Signal Input lists are dynamic by nature, expanding and decreasing as the valid
data changes. However, they are statically defined for DMX. All 24 inputs and 20 channels are selectable
at any given time through DMX.
Lens Control Limitiations
WARNING: Normal ILS control of the lens horizontal and vertical positions by the projector respects the
boundaries of the lens keepout area. This area is necessary to prevent damage to components within the
projector. When the DMX controls are used to set the absolute position of the lens, setting values in these keep
out areas may result in an unwanted final lens position. The user must ensure that any interim or final lens
positions, at any time during the lens movement, do not enter the keep out area.
