Thread: Could Pixelmad control up to 60 Universes of DMX?

  1. #21

    Tested 240 Universes Pixelmapping...

    Yesterday I tested a 240 universe Pixelmad patch. (1600 Fixtures)

    For starters I just tested on my MacBook Pro - and it did not run stable...
    Application freezes after a few seconds - even faster if you have the Pixelmixes window open.

    Seems to be to too much work for the MBP - I will try it on my 8xCore as soon as possible.

    yes i think so. way too much for a poor little laptop.

    ..But the poor little laptop managed to drive 120 universes of ArtNet (all in Broadcast with 100bT-nodes)...

    Parts of the HUD GUI do not work with the Pixelmix window open - so I believe these 120 Universes are close to the edge...

    I might have an installation coming up were I will need 200 Universes - but this will have to run on an 8xCore Macpro and for sure not on a laptop...

    its this 'broadcast mode' that totally overwhelms your artnet boxes.
    ( then people blame me... )

    people trying this - must route the data to individual addresses. really or it wont work well at all.
    Especially as many of the artnet boxes only do 10BT.

  5. That is right. Unicast is much better than broadcast.
    However it depends who's ArtNet boxes you're using. Our Ethernet-DMX8 can cope with up to 100 universes in broadcast (actually never done a test above).
    But as unicast is possible, it is always better, because many devices don't have that processing power to process all the data, to check if it is a universe they have to output.

    i dont think some of the artnet boxes can even run 10 universes @ 25fps without halting. let alone 100!.
    They just dont seem to expect this amount of data.

    Indeed, that is where we make the difference ;-)
    A lot of processing power on board to handle a large amount of broadcast data.
