If I was to purchase some generic strips of fairly inexpensive LED to test this out;
I'm assuming you're interested in testing pixel tape of RGB Individually controllable pixels, correct? Also there is a lot of different brands out there and most have proprietary hardware but since you mentioned Enttec, I'll use that as an example.
- To get the signal out of Resolume, and turned into ethernet signal (do I need Enttec USB? - ethernet? Wifi?)
You'll need connect into your pixel hardware which could be DMX (XLR3 or 5), USB or ethernet (RJ45). For instance Enttec Pixie Driver takes DMX or USB (Artnet) and the Enttec Pixelator takes ethernet (Artnet)
- To get the signal from my booth to the stage (ethernet? wifi?)
WIFI will work when you're in tech but the moment you put the audience in there it becomes unpredictable and unreliable so definitely ethernet! Most theatres out there have ethernet running from the booth to at least one side of the stage.
- To connect the ethernet / wifi to the actual LED strips (another converter? wifi receiver?)
Once you've connected your computer to the pixel hardware, you'll need a way to send power and data to your strips.
So for instance the Pixie Driver comes in 6 different versions (5V, 12V and 24V both with 1 or 2 power supplies) and all you need is to connect your pixel tape to the adapter (data, VCC and Ground). If you want to driver pixel tape that's far from the Pixie Driver, it will require the PixieLinker to get the data out, a CAT6 ethernet cable and a PLink Injector to get the data in and add power (5V, 12V or 24V using appropriate DC PSUs).
The pixelator has 24 PLink ethernet output ports so all you need is ethernet cables and Pixie Injectors with appropriate DC PSUs to get the data in and add power or use Pixie Drivers with Ethernet to DMX cables.
As a note, the PLink system pairs two universes to give you control of 340 RGB pixels (since it requires 1020 DXM/Artnet channels). That means the Pixelator can drive up to 8160 (24x320) RGB pixels.
I hope this helps!
