ABSTRACT:
A memory programmer interface for an electronic demand register includes conductive pads on a circuit board within a housing of the electronic demand register and spring-pin connectors which fit through slots in the housing of the electronic demand register into resiliently urged contact with the conductive pads. In the preferred embodiment, the conductive pads are enlarged solder pads associated with a non-volatile memory in the electronic demand register. A pair of alignment pins on the memory programmer guidingly enter alignment holes in the housing and/or the circuit board of the electronic demand register to provide alignment between corresponding ones of the conductive pads and the spring-pin connectors. The memory programmer includes a power source sufficient to energize at least selected portions of the electronic demand register and a control signal generator for generating control signals including a signal for maintaining a microprocessor in the electronic demand register in the reset condition. The electronic demand register includes a circuit for permitting a microprocessor therein to be held in a reset condition while the non-volatile memory therein is being read from or written to.
