As a tool to assist technicians working in networked systems using Streaming ACN, I have been working on a program to allow levels on a Streaming ACN network to be viewed, and levels to be controlled.
Streaming ACN is the protocol used to transport levels in a Net3 system, similar to EDMX in a Net2 system.
This tool is not affiliated with ETC, but may be helpful in diagnosing problems in ETC systems. It will monitor the levels output to Streaming ACN on Net3 network capable products including Congo, Eos, Ion, and Paradigm.
