Abstract: A data processing system includes a scanning head for electro-optically reading bar code symbols and decoding such symbols into digital decoded signals; a host device having a predetermined data exchange format for exchanging data and control signals with peripheral equipment; an interface arrangement for interconnecting the host device and the scanning head, including a first connector for direct connection to the host device, a second connector for direct connection to a head cable connected to the scanning head; and a conversion circuit for converting the digital decoded signals from the scanning head into digital data signals having a format compatible with the predetermined data exchange format of the host device.

Abstract: A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edge of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
