Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
