Can you expand on this? Does the in/out just turn into a coupler if power is removed? If so, is there a delay when power is applied before the "switch" is active? Am I misunderstanding what you're saying?Hi Mike,
If you're going fixture to fixture with sACN, you likely won't have an issue. sACN is used on a lot of major tours and festival rigs. And, Elation has gear on a lot of those rigs.
That said, it's probably best to use a quality switch to distribute out to each Truss (or position, or whatever). Most of our fixtures have relays on the Ethernet ports, so that they can pass data even if they lose power. I am not certain if other manufacturers are doing the same.
