ABSTRACT:
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.
