Frequently Asked Questions
Find answers about device roles, DMX system planning and technical information.
Device Roles
Understand how the main DMX Series fit into a lighting system.
Which DMX Series are available?
OLIDMX devices are organized into DMX Control Series, DMX Repeater Series, DMX Decoder Series and RF PWM Dimmer Series.
What does a DMX decoder do?
A DMX decoder converts incoming DMX control data for a compatible PWM or SPI lighting output. Read the guide to DMX decoders.
What does a DMX data repeater do?
A DMX data repeater routes an incoming DMX data path to separate system branches. Learn more about DMX signal distribution.
Installation and Technical Information
Use verified information when planning and installing a lighting system.
Why are cabling and termination important?
Correct DMX cabling and suitable termination at the final device on a line support stable operation of the control chain. Read the guide to DMX cabling and termination.
Where can I find technical specifications?
Technical details are added to each device page after they have been verified. Contact OLIDMX for information not yet listed.
How can I request help?
Use the Contact page for device selection or technical support requests.
DMX System Planning
Plan the signal path, addresses, and control approach before commissioning.
What is the difference between a DMX controller and a DMX decoder?
A controller provides the control data for a lighting system. A decoder converts assigned DMX data into the output-control method required by compatible lighting. Read the guide to DMX decoders.
What is a DMX universe?
A DMX universe carries up to 512 control channels. Larger systems can use more than one universe, so records should identify both the universe and the start address. Learn more about DMX addressing and universes.
How should I plan DMX addresses before commissioning?
Document each device location, universe, start address, and intended mode before testing the system. A clear address schedule makes commissioning and future changes easier to manage. Read the guide to DMX system planning.
What is the difference between DMX, Art-Net, and sACN?
DMX carries lighting-control data along a lighting control path. Art-Net and sACN are network protocols that can transport lighting-control data over Ethernet or IP infrastructure; support must be confirmed for each project. Learn more about Art-Net and sACN.
