ABSTRACT:
In a microprocessor-operated system controller having a light source operated by the microprocessor for indicating the general operating status of the system controller, an apparatus and method for providing ground isolated system diagnostics of data transmitted from the system controller. The apparatus and method is comprised of means for superimposing a bit rate data transmission upon the light source when in a visual ON condition and a ground isolated optical receiver for receiving the superimposed bit rate data transmission, decoding and converting the data transmission to a corresponding electrical signal, and transmitting the bit rate data for interpretation in a monitor device such as a computer and printer.
