Have you checked out the "How To" Videos at the
CQC site? They are located under the "Support" tab. That is probably the best place to start.
Unfortunately there are no "out of the box" guis with CQC. Because it is so flexible, it is basically impossible to create even a simpe gui because they are all so system dependant.
That being said, there are a lot of resources (including guis that users will share) on the C
QC user form.
You can also use the Administrative Interface to control any driver that you have loaded into the system. So while it isn't a nice GUI, you can manually play with things to make sure the lights turn on as expected and you can arm/disarm the alarm, etc, etc, etc.
