  • Patent number: 5335267
    Abstract: A monitoring apparatus includes a conversion module having firmware embedded therein for converting text data in a first code such as ASCII to binary text data in a second code such as facsimile scan line code. A memory module is connected to the conversion module for facilitating communication of text data in a first code between the conversion module and such memory module. An analog module is connected to the conversion module for interfacing the modem with the telephone line. The apparatus is arranged to monitor a parameter of a controlled process variable, e.g., temperature, signal strength, humidity or the like and responsively generate text data in a first code. The apparatus converts such text data in first code to binary text data in a second code and transmits such converted text data directly to a facsimile machine. Such operation is accomplished without the use of a PC or floppy or hard discs, program cards or other PC-like devices.
