Could Pixelmad control up to 60 Universes of DMX?

[OlliR]

It will be an area of around 400 square meters lit by LED tiles 20 cm by 20 cm.
That makes 25 fixture per square meter and a total of 10000 fixtures - if you consider each tiles as a single RGB fixture - would be 2000 fixtures of you consider a row of five tiles as a fixture. Anyway it results in 30,000 channels of DMX that would be about 60 universes...

The pixel array size is still important as it will not be compact like a square but the fixture will be more distributed... My guess right now is an image size of 200 x 200 would be fine...

For now I will pass on the info that 60 universes are possible - that sure is a winning point :-)

I will get back to you as soon as I know some more...

Thanks so far,

Olli

I can do a demo build for you -and we can see what problems emerge.

show i just did works fine at 25fps with around 28 universes - in one continuous viewable image.

Olli.

I just posted a version with 30 universes.

I have another one ready with 60 universes?
Would you like to test it?

Has anyone already used that many universes in real situation?
Will the ArtNet nodes be able to cope with all the broadcast data?
If been doing test with our units up to 30 universes running fine without hickups. But actualy I did not had a good opportunity yet to test it with much more universe at high refresh rates. I did with 60 universes (8 x Ethernet-DMX8 boxes) but only at a refresh rate of 18 FPS. The software and system I was using at the time could not do more.
I can imagine that some uProc devices won't be able to read all broadcast data.
I would advise to check this when going for that many universes. I'll see if I can do some more decent test on our Luminex boxes.

i added a routable data - rather than broadcast - option to the current version in january - so you can use a switch to route the data to to each box individually.

Which g5 where you using - what speed?

[bswinnen]

Great. So you actualy can talk to individual IP addresses?
That's good to know. At least this will not overload the nodes, however with 300Mhz processing power in our boxes we do have some margin
About G5: I do not have a PixelMad. We did some test with a PixelDrive and that one only broadcast data. We only use it to test our nodes to real live situations.
