At the time of this post, there are two primary places to get your hands on Event Source Configuration Documentation for ones that are supported:
1) The enVision application Help system - one of the first items in the table of contents is Supported Devices. Under that heading, click on the Configure Devices topic. Click on the Supported Devices link on the page that appears, and you will find links to the configuration documents in the Configuration column.
2) In Secure Care OnLine (SCOL) - Please note that these may be more up to date than what is in the enVision help file (especially true if you are running an older version), but access to SCOL requires a valid maintenance agreement.
