What is the maximum number of patched sACN (streaming ACN) universes supported by one CEM3 (Sensor3) controller?
If more than eight universes are present in your configuration, then the rack will refuse to load the configuration file.
Airflow modules are provided with an sACN address in the background, which you can see via an ODS export of the rack configuration from Net3 Concert. This addresses allows the Airflow Modules to stil be seen by the rack, which allows you to change to another module type if needed. These addresses DO count against the universe count in your rack. If these addresses are in universes you are already using, or set to 0/0, then they should not have any impact on the count.
