send to artnet universe 2?

[stanelie]

Hello.

Could someone tell me how I can send channel 1 to artnet universe 2 channel 1?
I see a "separator" character config option set to a dot, but no idea how or where to use it.

Thanks!

I was unable to search the forum, the search appears to be broken, I always get a "The following words in your search query were ignored because they are too common words:" error, regardless of my search keyword or keywords

In the patch, enter address 2.1 for universe two, first address. Numbers without the universe portion are assumed to be the first universe. eg. 1.1 is the same as 1.

The preference setting you saw changes the notation. For example you can set that to "/" and have the universes appear as 2/1 instead of 2.1.

Thanks for this info.

Now, I'm using LxConsole to help me create an Artnet device. I've noticed that LxConsole will stop sending ArtDmx frames when I switch my device to Universe 2 (instead of the default Universe 1), unless I set the output to broadcast.

Is this expected behavior? How does LxConsole decide to send packets or not?

Also, what do the 3 fields 00-0-0 -> mean in the Art-Net Nodes window?

When using the Art-Net polling mechanism, LXConsole will unicast to nodes that have been detected and that match the output universe. If a node does not send an ArtPoll reply that indicates that it is outputting a specific universe from the network, you can still send to that node by sending to a broadcast IP address, bypassing the ArtNet detection mechanism.

In the settings->DMX Out window there are two buttons that pertain to this. One is "Art-Net Nodes..." which shows the results of ArtPollReply messages received by LXConsole. The other is "Configure Universes..." which patches local universes to output universes. The PortAddress settings are Net+Sub-Net+Universe as defined in the Art-Net specification: https://art-net.org.uk/downloads/art-net.pdf

Ok, thanks for this info.
The part with the net-sub-net-universe is still unclear to me, but I will try to figure it out.

There's a section on page 9 of the Art-Net specification (linked previously) that covers addressing.

The following is from the terminology section on page 10:

Port-Address: one of the 32,768 possible addresses to which a DMX frame can be
directed. The Port-Address is a 15-bit number composed of Net+Sub-Net+Universe.

Net: A group of 16 consecutive Sub-Nets or 256 consecutive Universes is referred to as a
net. There are 128 Nets in total.

Sub-Net: A group of 16 consecutive universes is referred to as a sub-net. (Not to be
confused with the subnet mask).

Universe: A single DMX512 frame of 512 channels is referred to as a Universe.

So, in the nodes view, those 3 digits groups under an artnet device are the net, sub-net and universe, in that order?

[admin]

Yes, that is correct.

Thanks a lot, this was a great help!
