I'm have to use an Art-Net system with Ma NSP.

I'm not quite sure to understand the dmx settings voice "System" of Avo in the configuration of Art-Net Node.

And just to be sure, I can set the same IP to 2 different Line but I have to set different Universe. And the Universe must be the same of the NSP output line (e.g. NSP output line A -> Universe=1)

I've alwas been as confused about the 'Art-net system' thing as you are now. I haven't found it in the Art-net spec, but I tend to remember someone telling me (years ago) that this might be for future Art-net versions. I might be wrong, maybe someone else has more insight. In general, just leave 'system' at 0 (zero).

I have a bunch of several Art-Net sinks, but no NSP. The IP address (of the Art-Net module) must be that of the 'target' ArtNet node - in your case the NSP. (It's possible to use broadcast, depending from the network mask this is an address like 2.255.255.255 - but I always recommend to use unicast, i.e. the direct ip address of the target node).

Then, since it's possible to have >1 nodes in one Art-Net network, of course you can assign several Art-Net targets (and thus several target IP addresses) to one line.

Furthermore, it's possible to send several DMX universes via ArtNet, and thus, you need to assign the DMX lines (of ArtNet) which the signal should be sent on. In turn, usually you can do the same assignment on the node side, telling the node which ArtNet universe to output on which DMX 5pin connector.

In total, you can make this easy, or complicated.

An easy setup might be:

- console IP: 2.0.0.1
- ArtNet node IP: 2.0.0.10
- in the desk, assign ArtNet with IP 2.0.0.10 to line 1, and select ArtNet universe 1
- in the node, assign ArtNet universe 1 to be output at DMX-connector 1
As a result, everything patched on the desk's line 1 will be output at the node's DMX output 1.

A more complicated:

- console IP 2.167.48.12
- node #1 IP: 2.77.189.224
- node #2 IP: 2.10.84.193
- in the desk, assign ArtNet with IP 2.77.189.224 to line 7, and select ArtNet universe 3
- also in the desk, assign ArtNet with IP 2.10.84.193 to line 7, and select ArtNet universe 4
- in node #1, assign ArtNet universe 3 to be output at DMX-connector 5
- in node #2, assign ArtNet universe 4 to be output at DMX-connector 2
As a result, everything patched on the desk's line 7 will be output at node #1's DMX output 5, and at node #2's output 2

And finally:
- not every node is as configurable
- not every node reacts to the desk's ArtNet poll (and then shows up in the node list automatically)

Please feel free to go on asking, or send me a mail or PM in case of problems.
