An apparatus for communicating a vehicle parameter to a location remote and apart from where the vehicle parameter is measured is disclosed. The apparatus comprises a sensor responsive to the parameter being measured, with the sensor producing an output analog signal proportional to the vehicle parameter being measured. The output analog signal is subsequently converted into a digital signal whereby the vehicle parameter being measured is represented by an N-bit digital code. The N-bit digital code is subsequently transmitted to a location remote and apart from where the vehicle parameter is being measured, and is converted into a continuous analog signal representing the vehicle parameter being measured. The analog signal is subsequently displayed in a viewer usable form. The disclosed apparatus also includes a calibration means which simulates the sensor output analog signal and is switchable therewith to enable end-to-end calibration of the disclosed apparatus.

An apparatus for communicating a vehicle parameter to another location on the vehicle remote and apart from where the vehicle parameter is measured comprising: (a) sensor means responsive to the vehicle parameter being measured and producing an output analog signal proportional to the vehicle parameter; (b) means periodically converting said output analog signal into a digital signal whereby the vehicle parameter being measured is represented by an N-bit digital code; (c) calibration means simulating said sensor means output analog signal and switchable to said means periodically converting said analog signal into a digital signal thereby providing calibration for the apparatus; (d) a transmitter in communication with a demodulator by means of a hardwire link constituting a portion of the vehicle\s existing wiring, said transmitter transmitting said N-bit ditital code from means for periodically converting said analog signal into a digital signal through said existing vehicle wiring to said demodulator which receives said digital code; (e) means periodically converting said N-bit digital code representative of the vehicle parameter received by said demodulator into a continuous analog signal representative of the vehicle parameter; and, (f) visual display means whereby the continuous signal representative of the vehicle parameter is displayed in a user viewable form.
