Apparatus and Method for Controlling Access to Remotely Located Equipment

摘要

An apparatus and method for controlling access to remotely located equipment are disclosed. The method includes receiving a request at an access control module (ACM) from a host controller to provide a serial number associated with the ACM and communicating the serial number to the host controller. In response to communicating the serial number to the host controller, the ACM receives a calculated unique key from the host controller and compares the calculated unique key with a unique key stored in a microprocessor associated with the ACM. If the calculated unique key matches the stored unique key, the ACM generates an actuation signal and communicates the actuation signal to a fail-safe switch assembly in order to activate at least one component of an electronic locking structure.
