EOS and other console – Output Merging


Hello,

This month I will present ETC EOS and lighting fixtures Set (6-10 DMX universes). Also MA will be present to playback already programmed show. How to do LPT merge from both consoles? How/What same protocol they can “speak” to each other (network (artnet?), …)?. What kind of a device to do LTP merge do You recommend?

Greetings,

Adam

  • We've done something similar to this in that we've merged Art-Net from Eos with Art-Net from PixelMAD to drive 6 universes of Color Web. The Art-Net merge was provided by Artistic Licence Art-Net to DMX nodes - these boxes will detect two streams of Art-DMX on the Ethernet input and automatically merge them. For our show we merged on a HTP basis rather than LTP. I'm not sure if the Artistic Licence nodes can be set to LTP merge, but I'll see what I can find out.

    This worked out well for our show, and the hardware involved was very simple in that the PixelMAD and Artistic License nodes just plugged into the Eos network, and the DMX output from the nodes was a merge of PixelMAD and Eos.

    If you do this there are some things to be aware of - if Net 2, Net 3 and Art-Net are enabled on the Eos then it will be broadcasting each universe three times on the network, which can cause unnecessary loading - so it is worth disabling those protocols you don't need - also on the MA if it is also broadcasting other DMX over ethernet protocols other than Art-Net. In Eos 1.4.2 this should be a lot easier to manage as the enabling / disabling of protocols should be available through the shell.

    There aren't actually any devices that can do an LTP merge between disparate consoles.

    In ETCNet2 and ETCNet3/Streaming ACN, we have the concept of "Priority" - this is where you can decide which source is the most important.

    Unfortunately MA Lighting havent yet implemented Streaming ACN into their products, so you'll have to use Art-Net.

    Art-Net only supports an HTP merge between two sources - it doesn't do priority or handle more than two sources.
