Channels and Fixture Control
Each DMX channel carries a control value from 0 to 255. Fixtures use one or more channels for attributes such as intensity, color, position, or effects.
OLIDMX
Control hardware for DMX and ODX systems.
Signal Distribution
Route DMX data to separate branches where the system layout requires it.
Control and Gateways
Connect compatible control environments through dedicated system devices.
Lighting Signal Conversion
Use DMX decoder devices for compatible PWM and SPI lighting outputs.

Understanding DMX
The essentials behind a reliable lighting control path
DMX gives a lighting system a shared language: the control source sends values, and each addressed device responds to the part of the data stream assigned to it.
Addresses and Universes
A start address tells a fixture where to read from the stream. One DMX universe carries up to 512 control channels, so a clear address plan keeps devices independently controllable.
Signal Path and Distribution
Control data travels from the source through the installation. Repeaters can create practical branches, and the final device on a line is normally terminated to help maintain signal integrity.
DMX Beyond One Cable
Art-Net and sACN transport DMX-style data over Ethernet networks. RDM can add two-way device communication in compatible systems; not every installation uses these protocols.

Frequently Asked Questions About DMX Systems
Learn about the core layers of a DMX system and the DMX Series that suits your system needs.
What are the core device layers of a DMX system?
A typical DMX system uses control devices, repeaters, decoders and RF PWM dimmers to manage compatible lighting control workflows. Read the guide to DMX system planning.
How do I choose the right OLIDMX series for my needs?
Choose the DMX Series that matches the required system role, then review its listed devices for confirmed information. Learn more about the fundamentals of DMX.
