Abstract
An independent back memory module is disclosed that is permanently installed at a security gate installation. The memory module has a nonvolatile memory and it is positioned within the system so that it automatically has a communication link with any gate controller installed. The memory module records a history of the operation of the system. The memory module retains operational information regarding the system and information identifying the gate controller, gate controller board and the setup of the particular installation. The memory module also retains information regarding changes made in the setup of the system. Whenever a new gate controller board is installed information in the memory module is transmitted to the new controller board.
