A scanner for reading two-dimensional optical information sets is described which includes a housing for supporting a photosensitive array associated with an optical string adapted to focus optical information on the array. Also provided are array and optical string controls for controlling the array and optical string such that the output of selected images on the array are processed via pattern recognition means. Images recognized to contain decodable optical information are displayed and highlighted by a display. In addition, the scanner provides autodetect circuitry for determining the type of terminal to which it is attached and automatically converts the two-dimensional code information into an appropriate one dimensional format, as needed, for communication to an attached terminal.
