The DVC4 Gold does not have Art-Net.
The only product with Art-Net out of the box is the DVC4 Gold ZM.
You would be able to see the Art-Net node in Daslight, however you would need an Art-Net licence to allow access to it.
To purchase a licence you would need a Nicolaudie SUT device to synchronise with the purchase at https://store.dmxsoft.com/
Unfortunately the DVC4 Gold is not a SUT device. The DVC FUN is a SUT device however, as is the Sushi-DS.
If you wanted to upgrade your DVC4 Gold to a DVC4 Gold ZM or a DVC FUN, please contact our support team for more information on this. https://store.daslight.com/contact
