System is off lineb

What sort of device is your 1 port DMX? Is it USB based or network based? If you are using ArtNet as the network protocol to the DMX output device, then there is some additional settings in EOS that need to be made, because after the update it defaults to sACN and disabled ArtNet.

Thanks I have ArtNet connection to DMX port, Where would I find the sACN to change setting , where in the shell?
