Abstract:

A self-contained, portable memory module for transferring configuration data from one programmable panel controller to another. An internal replaceable lithium battery is provided for powering the memory integrated circuit chip when the module is not connected to a powered controller. The battery and module are interconnected by a three wire battery lead that can be plugged into the module in either direction. The module also has a hinged case with molded feet allowing the module to be stored upright on a flat surface to prevent damage to the internal lithium battery. The module further comprises a connector, recessed for protection from static electrical discharges, for interfacing the module to the controller, and a special battery connector which allows battery replacement without loss of the stored data.
