Issue
My system is setup with a console sending sACN data to a Paradigm processor (P-ACP), which then gateways the sACN to DMX for communication to the rest of the system. I have my console's sACN priority set higher than Paradigm's, and when the source goes away Paradigm is having trouble taking over.
Explanation of Issue
This is most likely due to the sACN Data Loss Behavior of sACN on the P-ACP. The default behavior is "Wait and Fade" after 3 minutes. The P-ACP will hang onto the last look from the sACN source, before turning it off after the designated time. It's also possible the behavior was changed to a longer interval of time, or could be set to "Hold Last Look", which hangs onto the last look forever, or until the source returns, or the P-ACP is rebooted.
