The reason the node is invisible is that it does not properly support the full Art-net protocol. Eurolite is a budget brand, and like most budget hardware, you end up paying in time what you’ve saved in money.
First, ensure that the Mac and the Eurolite node are both physically connected to the same network and are both successfully communicating with that network. It’s much easier to do that for the Mac; I don’t know what kind of configuration or troubleshooting tools are available for the Eurolite node.
Next, make sure the Mac and the Eurolite node are both using IP addresses which are compatible with each other and with the network. For example, if the network has a router with an IP address of 192.168.1.1, your Mac and the node could be addressed as 192.168.1.2 and 192.168.1.3, both with subnet masks of 255.255.255.0.
If you think this is all correct, you should be able to open Terminal and ping the node by typing:
ping 192.168.1.2
(replace that address with the actual address of your node.)
If you see something like “Request timeout for icmp_seq” then the Mac is not able to contact the node, and you have a network problem.
If you see something like "64 bytes from
192.168.1.1: icmp_seq=0 ttl=64 time=0.807 ms” then your Mac is successfully contacting the node, and you have either a QLab patching problem or a node configuration problem.
I’d try these things and see what they yield.
Good luck!
