Max DMX external for Windows

novasnoa's icon

Hello dear people,

i recently bought some DMX lights and want to control them from my Windows Tablet and Max.

I have quiet a lot of experience with creating midi and osc sequencers in Max but i need a little start help for dmx.

  1. Is there an interface that is recommendable and has a working external?

  2. Is my Idea, that i can just send values between 0-255 on many of the 512 channels and create nice evolving light-scenarios possible or will there be issues (like performance etc)?

  3. are there maybe even finished patches to check out?

I am grateful for any answer!

Hi Robert,

to send DMX data from Max you will need an DMX adapter. The technical details how to send DMX data is unfortunately hardware (adapter) specific - it differs from device to device. That's why there is no external ready for that.
A popular here and reliable interface is the Enttec USB DMX Pro. It's easy communicate with via the [serial] object and you will find example patches here in the forum.

Hey Jan,

thanks alot for that inside.

You use "adapter" and "interface"... I guess they are the same or is there a difference? Do i need an adapter and an interface?

I did not think it would be possible to address an usb interface directly. I will read about the [serial] object.

The Enttec USB DMX Pro was already on my list.

Well yes, I should have used "interface" only. That'll be the correct term.

For the ENTTEC DMX USB PRO, I'd say it's the one you will find most support and example in this forum.
It shows up as a normal serial device, so it can be addressed directly out of Max.

Jut be aware: the cheaper version OPEN DMX USB is more complicated to handle. AFAIK you would have to send every DMX frame separately, with correct timing. The Pro handles that for you, you just need to tell it which DMX channel you want to set to which value once. It'll take care of the rest.
