Multiple output protocols - tricks?

Does anyone have any tricks for patching using multiple protocols?

As it stands, my house has Universe 1 going to the house dimmers via sACN

Universe 2 is a DMX dry line.

and I've just acquired a 4-port art-net node that I'm going to throw into Universes 6-9.

Is there an easy way to assign a protocol per universe? or do I have to assign the protocol for each channel as I patch?

Ideally, I'd love to be able to assign a universe a default output protocol in settings instead of one global output protocol.

Other than outputting every protocol to every Universe, does anyone have any tricks?

Thanks!

  • Sorry yes actually it would be the same bandwidth for both so that was not a valid scenario, was momentarily thinking unicast. 

    My point was the actual bandwidth used is neither significant given modern connectivity nor really different.  The only difference is the receiving device in the broadcast artnet scenario has to look at  the UDP packet to see whether its for its universe, whereas for sACN multicast the IP address in the packet is inspected by the ethernet hardware to see if its for a universe the node is wanting.

    However given the processing speed of whatever is doing this in node and the fact its not got anything else to do anyway, its does really make much practical difference.   The only argument for why it would matter is if the network was also being used for other purposes and you didn't want the broadcast traffic to putting a load on that. 

  • There is no real difference in processing speed of ethernet hardware. Try program a node with an Arduino and Ethernet Shield. Yes the sACN packet is a little bit longer and you have to check some parameters more, but you have a clean network which is not flooded with bullshit data.
    And you forgot the node ethernet hardware must proceed every packet completely which comes in. 
    Unicast is an option that only works if all components support ArtNet4, did all your ArtNet hardware do this?

    Very good point, completely forgot about that class of device which is somewhat ironic as I actually write code for them!!
