In LSP have you configured your controllers to output E 1.31? Yes using "Configure Outputs"
Secondly, once you get the E 1.31 set, you have to go to "Configure Controller Output Plugin." In that process you select "Multicast (Lynx Express ...)" It will set up a bunch of channels and universes for you to use. I went to "Configure Controller Output Plugin" but not sure if I did everything properly
From there you should be golden to output to the LEs. Still no output
My assumption is that you have flashed the EtD with DMX - if it is flashed for Pixelnet, you have to go through an SS Active Hub and set the controllers(LEs) up differently. Yes, I did flash with the DMX firmware.
