AUTONOMOUS SMS REMOTE MANAGEMENT DEVICE FOR PRINTERS, COPIERS AND FAX MACHINES

摘要

The present invention consists of an electronic device which allows remote management of printers, copiers and/or fax machines (henceforth remote units), that is, without requiring connection to a computer. It consists of three main modules: an SMS terminal; a controlling card; and the case. The controlling card consists of a digital system comprising a central processing unit such as a microcontroller, and a set of peripheral integrated circuits which define the following functions for the system: 1) the series connection of the SMS terminal, such as by a UART 2) connection to the remote unit by a port extension chip, such as integrated 8255. 3) Storage of the program and data in a local memory. 4) Management of the error protection and power system.
