ArtNet I and ArtNet II

[mrgoose]

Hi all, a quick post to see if someone can explain me a point about ArtNet I and ArtNet II. I'm using very oftenly DMXworkshop with a Ethernet-DMX 2 from Luminex. Everything works perfectly fine as soon as I use ArtNet I mode.
But I would like to understand why my streamed universe is blocked when I use ArtNet II mode (unicast). I've checked with Wireshark software if there was a difference, but to be honnest I don't see any difference? Artpoll et Artpollreply packets looks quite the same. I 've also checked the latest ArtNet II specification, but I don't see which of the improvment you've done could blocked the streaming. ArtNet II is given to be fully compliant with ArtNet I. I see in the DMXWorkshop menu "Artnet Routing" that my universe is blocked. Can somebody explain me why ?
Many thanks

Hi,

Two answers:

1) Art-Net I had a limit of around 40 universes because it was Broadcast. Art-Net II removes that limit by using Unicast. Art-Net I and Art-Net II are compatible on all Artistic Licence products.

2) The 'Blocked' message you see is because of the configuration you have set in DMX-Workshop's preferences screen. There is an option which allows broadcast Art-Net I to be blocked if no data is being sent on a given universe. To resolve this, simply untick the option in preferences which will allow full Art-Net I Broadcast operation.
