Constructs
Features of the fixture (such as color mixing, lithos, rotating lithos, color wheel, iris, frost and
shutter). Constructs can be used by a controller to program your overall show.
Dichroic
A dichroic (from Greek, meaning “two-color”) filter achieves a richly-saturated color without
using any pigmented (colored) materials. In simple terms, it achieves this effect by either
reflecting or “cancelling out” through destructive interference all but a narrow range of the
light spectrum.
The “dichroic” name refers to the fact that one color (or set of colors) is reflected or cancelled
out, and one color is allowed to be transmitted through the dichroic filter.
The dichroics used in Cyberlight are all manufactured at the High End Systems Optical
Coating and Assembly Laboratory in Austin, Texas. They are made from a base of Pyrex
®
-
like glass material coated with multiple, microscopic layers of specialized materials separated
by junctions that either transmit or reflect certain wavelengths of light, accounting for the
resulting color.
Dichroic filters offer a number of advantages over traditional gel filters: since they are made of
Pyrex-like glass and absorb almost no heat themselves, they theoretically have no failure
mechanism; they transmit more light than gels; and their resultant colors are more richly-
saturated than is possible with a gel.
Dichroics are currently used for all Cyberlight colored lithos, color mixing flags,
effects and of course the color wheel dichroic filters.
Before installing a dichroic or litho
in Cyberlight, make sure you read the section titled “Removing and Installing Rotating Lithos”
on page 3-19 and the section titled “Replacing Dichroics/Lithos in the Color Wheel or the
Static Litho Wheel” on page 3-22.

DMX 512 control protocol
DMX 512 is a standard method of controlling lighting fixtures and other devices (such as
lasers and hazers). Developed by the United States Institute of Theatre Technology (USITT),
DMX 512 is supported by leading entertainment industry equipment manufacturers, such as
High End Systems.
DMX 512 (D for digital, MX for multiplex and 512 is the number of channels per link) is a
reliable, efficient and well-understood method of controlling lighting devices. Its strength lies
in the ability to control a large number of different types of devices made by various vendors
on the same link using any DMX-compatible controller.
See also “LWR control protocol”.
DMX address
The DMX 512 protocol allows a total of 512 addresses to be used on a particular link. (A link
is a group of devices connected on a daisy-chain of XLR cabling.) You need to assign a unique
fixture number to each Cyberlight you wish to respond independently to control commands.
