DMX512 is the communication standard used to control stage lighting systems. Each universe of DMX has 512 channels of control. These channels are used to control attributes of a device (intensity, pan, strobe, haze, etc... ) by sending a value between 0 and 255. A device can use one or more DMX channels however all a device’s channels must be on one universe. The first channel of a device is the starting address, and must be set on the device (see your devices manual).
History of DMX512: DMX was created in 1986 for lighting control in show and stage use and combined the wishes of different manufacturers and users. DMX spread quickly and is now used all over the world.
What is universe? The DMX protocol defines 512 channels per universe of DMX. In order to control many devices, especially if each have a lot of channels, you need more universes.
It is standard professional practice to group devices by type and/or location cross the DMX universes. This makes it possible to add a couple of devices, without repatching your entire theatre. Some rules of thumb are:
The dimmer should be patched to DMX address 1
Hazer / Smoke machine should be at the end of the universe (512)
Start each new block of devices at each 50th or 100th address

Which kind of devices are on the market and what is possible?
A Device is a lightsource whose light beam is formed by a reflector or a lens.
There are a lot of different types of devices. Here we introduce the most important ones: Dimmer, Color Changer, Flower, Scanner, Moving Head
There are devices with one channel or multichannel devices.
One channel devices can be set as Generic Dimmer 1ch. So every device is on one fader. Please make sure, that the DMX-Address is set correctly at the device.
A simple example of multichannel is e.g. a RGBW-Device. You can handle this like above, or choose the right device in the device library. Please be aware that the device template library may contains mistakes. These are templates build with the device manufacturers datasheets and manuals.
