5 Programing Notes

The IMPRESSION X4 Bar's unique layer effect system allows for a wide array of
dynamic pattern effects using a minimum of DMX Channels. The example below
demonstrates how to program Set Layers in Normal Mode to show how the layer
system works.

5.1 Guide to the Set Layers

A "Set Layer" is a group of control parameters such as color, intensity, and pattern.
A lower layer is revealed when a pattern is applied to the layer above it. Applying a
pattern to layer 1 reveals layer 2. Applying a pattern to layer 2 reveals layer 3. In other
words, Set Layer 1 is on top and has the highest priority. Set Layer 2 is in the middle
and has priority over Set Layer 3. Set Layer 3 is on the bottom and has the lowest
priority.
Set Layer 1 and Set Layer 2 provide control of Color Wheel, Red, Green, Blue, White,
Intensity, Pattern Select, and Pattern Movement. Set Layer 3 provides control of Color
Wheel, Red, Green, Blue, White, and Intensity.
The Shutter and Master Intensity channels control all three Set Layers. Crossfade
allows for fade instead of snap in Set Layer Movement Effects. The Star Effect
randomly strobes all pixels.
Pixel Select 1-8, Pixel Select 9-16, Pixel Select 17-20 are for custom patterns. They
apply only to Set Layer 1 when Pattern Select is at DMX value 255.

5.2 Example of Set Layer Programing

Example notes:
 Fixture libraries from different console manufacturers vary on how channels are
patched to attributes. Some console libraries require that the fixture be a multi-part
fixture. Please check with the console manufacture or console fixture library editor
to verify the correct channel patch and layout.
 The channel numbers in parentheses apply to the Normal Mode DMX chart. All
values are in 8-bit DMX.
 In this example, Set Layer 1 is red, Set Layer 2 is green, and Set Layer 3 is blue.
For an example of Set Layer programming, proceed as follows:
1. Patch the fixture to a Normal Mode library and verify that the fixture is set to
Normal Mode. Select the fixture.
2. Choose the Shutter Channel (11) and take to value 255.
3. Choose the Master Intensity Channel (12) and take to value 255.
4. Choose Set 1 Red (6) and take to value 255.
5. Choose Set 1 Intensity (10) and take to value 255. All the pixels should be red.
6. Choose Set 1 Pattern Select (28) and take to value 8. This pattern reveals Set
Layer 2 on Pixels 6-20. Pixels 1-5 should be red and pixels 6-20 should be
blacked out:
7. Choose Set 2 Green (16) and take to value 255.
