What is DMX-512?
• A standard protocol for digital communication
• Commonly used to control stage lighting and theatrical effects (ex: moving lights, color
changing lights, fog machines, etc.)
• Also commonly used for color changing LED • Also commonly used for color changing LED

DMX-512 Standard
• DMX512-A is the current standard and is maintained by ESTA (Entertainment Services and Technology Association)
• The DMX 512 signal is a set of 512 separate intensity levels (channels) that are constantly being updated
• One DMX link of 512 channels is defined as a Universe •
One DMX link of 512 channels is defined as a Universe
– Typical theatrical consoles have multiple Universeoutputs
• Each level has 256 steps divided over a range of 0 to 100 percent.
• The DMX signal repeats all 512 intensities as fast as 44 times per second
DMX Wiring
• The DMX512 wiring follows the RS-485 standard (similar to QS digital link)
• Digital cable is run in a daisy-chain to each DMX device
• Each device is addressed to specific DMX channels

DMX Addressing
• 512 individual device addresses available per universe
• Device address is stored inside and set at the device
• Various methods used to assign an address
– DIP switch, LED display, Rotary Dial, Software

DMX Future
• RDM (Remote Device Management)
– Two way communication between controller and DMX device
• ACN (Architecture for Control Networks)
– Primarily designed for use on Ethernet networks
– Aimed primarily at theatrical applications
• Lutron DMX interfaces do not currently support RDM and ACN but can be connected to RDM compatible equipment
Output vs. Input
We define DMX signals as Output or Input
– DMX Output – signals sent from a control system
– DMX Input - signals received by a lighting instrument or control system

Combining and Splitting DMX
• Isolation Interfaces are required to combine or split DMX Signals

DMX Solutions
Basic Applications – DMX Output
• One or more zones of DMX devices
• Need static preset levels or scenes (called cues)

Basic Applications – DMX Output
• Applications with simple three color mixing of
– RGB (red, green, blue)
– CMY (cyan, magenta, yellow)
Basic Applications – DMX Output
• Simple three color mixing
• A zone is assigned to each of the three RGB colors
– The zone intensity of the RGB colors is adjusted
so when blended together they produce a new
color
– The resulting color is fixed in a scene
– Scenes of different colors can be selected manually (keypad) or automatically (timeclock or
sequencing functions)

DMX Solutions
Basic Applications – Sequencing
• Automated selection of multiple scenes
• A repeating pattern of changing color or functions over a period of time
• Simple sequences (4 -16 scenes) that are “stepped” in timed intervals (1
second - 10 minutes)
Complex Applications – Output or Input
– Require many channels (zones) of control
• Color changing applications
– Require a large number of scenes (cues)
• Sequencing of colors and levels • Sequencing of colors and levels
• Rapidly changing scenes
