Open Dmx-Interface implementation - how to?

Hi,

I am trying to create a program that will be connected to a DMX-Light-device. To connect that device to the pc i got the Enttec-Open-DMX-USB-Interface.

They have an C#-Class on their website (https://www.enttec.co.uk/product/lighting-communication-protocols/dmx512/open-dmx-usb/)
but now I am just struggeling to get a seperate script to send a signal to that device and I have no clue what I am doing wrong/ where I have to look to do it right.

So you'd be a great help, if you know how to send a dmx-signal to a channel

(I added the C#-class to the thread and my last small attemp to just get the lamp to go on)

 

did you solve your problem? I'm kind of trying the same thing atm

 

Please don't necro post to old threads. Odds are this person is long gone and in any case, necro-posting is against forum rules.

When you post vague questions, remember that we cannot read your mind.

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- links to documentation you used to cross-check your work (CRITICAL!!!)
- what actually happened, especially any errors you see

If you post a code snippet, ALWAYS USE CODE TAGS:

Well I wasn't aware, that responding to a post from Dec 21 is considered necro-posting. I just had the same problem as op, but I will provide more information next time.

 

Hi there, I don't think you were wrong to ask that question. It was merely a not super timely follow-up to a niche question with the slim chance for a solution.

I actually faced the same problem op was struggling with in February, and found a workaround/solution. As it stands, there is no way I know of to get the C# Open DMX protocol running from within a Unity application, or a dot net core application for that matter. (Missing libraries)

However, you can create a separate Windows Forms C# application that implements the Open DMX protocol. Now you just need to find a way to get the DMX512 byte[ ] from your Unity application to your Open DMX application.

If you want a quick and beginner-friendly solution, simply write to a file from Unity and read that file from the Open DMX program. The next best method is to turn your Open DMX program into a TCP server, and send messages to it from the Unity application.
A lightweight alternative to that, is to turn it into an HTTP PUT server instead, and send Unity Web requests. This is less performant (slightly more garbage generation) but supports most platforms with the least amount of hassle. And yes, a nice bonus is that you can control the lights from your phone as well

I ended up polishing my implementation and created a Unity plugin from it, which you can check out here: https://neoludic-games.itch.io/u-dmx, if you want to save a bit of time.

Let me know if you have any questions. I am happy to see more Unity devs explore DMX tech, cause frankly it is super cool what you can do with it!
