A universal interface driver application specific integrated circuit (UIDA) for a data reading device which supports multiple host interface configurations through the use of shared communications lines. In one application, the UIDA is a 32 or 44-pin TQFP chip located in a bar code scanner, or other data reader, connected to a host processing device such as a computer terminal. The scanner reads and decodes bar codes, transmitting the information to the host processing device through an interconnect cable using a host specific input/output interface protocol. The UIDA contains circuitry to support numerous different host interface protocols, such as RS-232C, IBM46XX, or Keyboard Wedge interface, in order to allow a single data reader to operate with a wide variety of host processing devices. The desired host interface for the data reader is communicated to the device through any one of various methods, such as by signals initiated from the interconnect cable itself or by scanning the information from a configuration bar code. The UIDA then selects the appropriate host interface protocol and configures the scanner for operation with the host processing device.

Universal interface driver system for data reader

An interface selection and configuration system for a computer peripheral in which configuration for the peripheral and/or the host interface is at least in part accomplished by the interface connector cable. In a preferred embodiment, the computer peripheral is equipped with one or more hardware interfaces. The interface connector cable has a first end connector for attaching to the computer peripheral. The first end connector of the interface connector cable is typically a multiple pin connector constructed and arranged to be properly physically and electrically connectable only to a specific computer peripheral or class of computer peripherals, the first end connector including at least one electrical connection between two pins for completing a circuit within the computer peripheral thereby enabling the computer peripheral. Where the peripheral is a data reading device such as a laser scanner or RFID reader, alternate or additional configuration may be obtained, with data reading device, from the label on the interconnect cable. The label, which may for example be a bar code or RFID tag, contains information or instructions by which the data reading device (and/or the host) is configured.
