Abstract
An automatic sensing and programming circuit for optical scanners which produces a diffuse volume of light substantially encompassing the scan volume of the scanner. A method for programming one optical scanner from another uses the circuit to emit a plurality of pulse trains which in combination represent a predetermined function or set of functions, each pulse train representing predetermined hexadecimal digit, and each pulse train including a predetermined number of binary pulses. A method of programming an optical scanner employs a plurality of tags which in combination represent a predetermined function or set of functions, each tag representing a predetermined hexadecimal digit encoded as bar code labels.
