A universal interface system for use with a data acquisition system including a data acquisition device such as a bar code scanner or scanner integrated terminal for providing digital data signals indicative of acquired data for transmission to a host device such as a computer, and a host device having host-specific input/output data format requirements. The universal interface system comprises universal data exchange means located in the data acquisition device for providing digital data signals in a universal data exchange format independent of the data format requirements of the host device; and a host interface cable coupled to the data acquisition device and to said host device, for transmitting acquired digital data from the data acquisition device to the host device, the interface cable comprising means for translating digital data from the universal data exchange format to the host-specific input/output data format requirements. The interface cable comprises a buffer for storing a host parameter data word used in communications with the host device. The universal data exchange means comprises a memory for storing a plurality of host parameter data words, each of the host parameter data words being associated with one of a plurality of different host interface modules; and means for reading from the memory and transmitting to the host interface module the host parameter data word associated with the particular host interface module operatively connected thereto.

An arrangement for decoding a bar code symbol in which the data resulting from scanning a bar code symbol with a bar code scanner is evaluated to determine if the scanned bar code symbol is within the working range of the scanner. The data acquired by the bar code scanner is evaluated to determine if the detected widths of the bars and spaces of the scanned bar code symbol are too small, less than a threshold value, which indicates that the bar code symbol is too far and outside of the working range of the scanner. Moreover, the working range of the bar code scanner can be selectively changed by changing the threshold value, which can be easily implemented by having the bar code scanner scan a menu bar code which instructs the decoder to change the threshold value to a selected new value which may be pre-established for the particular operation. The arrangement preferably includes software to process the data acquired by the bar code scanner, and if the data indicates that the scanning distance to the bar code is too far, a flag is set in the software which prevents a new decode result from being recorded. However, the intermediate decode result is retained in memory to indicate that the bar code symbol is still in the scanner's field of view. A second evaluation validation to determine if the detected bar code symbol is valid may also be performed.
