A DMX line has a topology
ETC recommends daisy-chaining devices and a 120 Ω end termination. Passive Y-splitting reduces reliability. Use a suitable active splitter when branches are needed.
A network carries multiple universes
Art-Net transports DMX512 and RDM data over Ethernet. sACN is another network protocol for lighting data. A node converts supported network data into a physical DMX output.
Diagnose one layer at a time
If a fixture does not respond, check power, mode, address and universe. Then check protocol and network configuration. A short known-good connection helps separate a device fault from an installation issue.

Is Art-Net the same as the internet?
No. It is a lighting protocol that can run on a local network.
Can a network switch replace a DMX splitter?
Not on a physical DMX line. They handle different connection types.
