ABSTRACT:
A hardware identification system is provided in a bar code reading arrangement including a main body and a plurality of modular detachable scanning heads connectable to the main body dependent on the application desired for the reader. Each of the heads includes a voltage divider dividing identification voltage and the main body includes a microprocessor including an analog to digital converter which reads the identification voltage, converts it to a digital signal and compares the identification voltage against a look-up table of identification voltages and their associated hardware element to identify the module type. Alternatively, or in addition, the module may be similarly configured to identify the main body by virtue of an identification voltage defined by a voltage divider in the main body. Alternatively the hardware identification system includes an electronic subassembly such as a PC board used for example in computer systems for automatic identification of hardware.
