Double check the patch window and ensure that your fixtures are patched to the correct DP and the correct dmx universes. This sounds like a simple thing to check but in some cases output is failing only due to a mis-patch. If you are still not seeing ArtNet output from the console proceed to step 2.
Open the network window (setup, network) and make sure the internal DP8000 is reporting "Outputs Active". It the DP8000 is being reported as "offline" then log off the show and click on the settings button in the start window. Ensure that "run internal DP" is turned on and set to the appropriate net number. Log back onto the show and check output again. If console is still not ouputting Art-Net the proceed to step 3 and continue troubleshooting.
Open the network window (setup, network) and click on the internal DP8000 to which the fixtures are patched. Click on the settings button. In the node settings window navigate to the "FixtureNet" tab. Ensure that the FixtureNet IP address and subnet are set appropriately for the network. Note: If you make any changes to the FixtureNet IP address or subnet, you must log off and log back onto the show for those new IP address settings to take effect.
Open the network window (setup, network) and click on the internal DP8000 to which the fixtures are patched. Click on the settings button. In the node settings window navigate to the "ArtNet" tab. Ensure that the artnet outputs are set correctly for both subnet and universe.
Connect a windows computer to the network and run a software application tool such as DMX Workshop. These kinds of software applications allow you to see artnet streams on the network and can be used to further help in detecting where the problems might be occurring.
