AOC SubsystemΒΆ
This section describes how to communicate with and command the AOC from IDL. More importantly, it discusses how to get the system aligned and running to best performance.
In the case of a total loss of AOC configuration files, you should be able to follow this guide and recreate all the files from scratch.
Most content in this section is by Lisa Poyneer. Contact her if you have concerns or questions.
