Hi Claudio,
The settings for Art-net input and output, as well as many other input and output settings are on the SETTINGS page. Once set up, you can feed the Art-net to the ELC Node through the SHOWCONTROL page. Easy start is to click the template 'Receiving Art-Net'
Now you should output the Art-Net received, following the input and output settings for Art-Net on the settings page.
For the recording you need to be on the TRACK page. Please note that the memory is divided between the tracks, so every track always takes the same amount of memory as the other tracks. You can change the amount of tracks in the settings page, 8 tracks are twice as long as having 16 tracks.
(Changing the amount of tracks will empty the tracks, so choose first. If you want long tracks with a lot of lights choose a low setting like 4 or
The tracks can be used as cues in the playback page.
To enable the emergency mode you can use the B-Station to send OSC in showcontrol. Use the source "OSC" and have a look at the task type "Actionlist"
You can use this to enable or disable the art-net feed from the lighting desks to the DMX node and lights.
You can also use OSC and Showcontrol to start the playbacks you want to be active during the emergency.
I hope this will help you on your way, if you have more questions please feel free to ask!
