Abstract:
An option-identifying system for identifying locations of a plurality of options that are electrically connected in cascade and mounted to a main body such that the options are attachable to and detachable from the main body:wherein the main body comprises a signal generating section that outputs a location-assigning signal having a plurality of bits to a first one of the plurality of options; wherein each of the plurality of options comprises: a data-storing section that stores the locations of the plurality of options and corresponding location data that describe the locations; and a location-identifying section that receives the location-assigning signal and compares the received location-assigning signal with the location data to identify a location of a corresponding option; wherein the location-identifying section inverts one of the plurality of bits of the received location-assigning signal, then rotates the plurality of bits of the location-assigning signal after inversion of the most significant bit, and finally outputs the location-assigning signal after rotation to a following option.
