1. A method for transmitting a report in text data from a monitoring apparatus to a facsimile machine, the apparatus being connected directly to process equipment by electrical leads for monitoring at least one separately-controlled process variable, the method including the steps of:

  • providing a conversion module within the apparatus and having firmware embedded in at least one semiconductor chip therein for converting a first code to a second code;

    transmitting a command set to the conversion module for selecting a facsimile mode of operation;

    implementing transmission of text data to the conversion module in a first code, the text data relating to at least one process variable;

    initiating a converting step upon the occurrence of at least one of a predetermined plurality of events including (a) receipt at the conversion module of a signal indicating the end of the text data and (b) the absence of text data transmission over a time in excess of a predetermined time;

    converting such text data to a second code using only firmware, thereby providing converted binary text data; and

    ,transmitting such converted binary text data from the apparatus directly to the facsimile machine, such converted binary text data being in the form of a report transmitted over a telephone line.
