Programmer for contact readable electronic control system and programming method therefor

摘要

Programmers for an entry control system, which operates to automatically control access to an area upon contact of an electronic key with a data port, employ data carriers housing ROM chips. The chips have a unique data code which corresponds to an elemental key or a code. In one form of the programmer, a membrane keypad addresses the ROM chips for inputting commands to program a controller. In other embodiments, the programming chips are mounted to a flexible board and are positionable to directly contact a receptacle port for the controller.
