ABSTRACT:
A computation and control module suitable for use in a variety of postal scales as well as other types of mailroom equipment is disclosed. The module includes a microprocessor and associated circuitry; connectors for connecting ROM, which store firmware for controlling the microprocessor, and PROM, which store postal rate charts; an input/output connector; a serial interface for communications with postage meters; a non-volatile memory for storing parameters specific to particular units; and an auxiliary input/output connector. The auxiliary input/output connector is driven by selected, memory mapped interface circuitry mounted on the PROM card. The module also includes a load cell interface and a power supply. In one embodiment switches, responsive to the microprocessor, are provided for sequentially energizing various connectors and interfaces, so as to reduce power requirements. Systems comprising a plurality of computation and control modules are disclosed. Other systems including battery powered modules mechanically and electrically interconnected by a power distribution bus are also disclosed, as a modular power bus.
