Multiple-interface selection system for computer peripherals

Abstract

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.

1 . A method for setting a function of a data reader comprising the steps of 
 selecting an interconnect cable corresponding to the data reader and a particular host device, the interconnect cable having a label thereon containing data which may be obtained by the data reader;    connecting a first end of the interconnect cable to the data reader a second end to the host device;    activating the data reader and the host;    obtaining the data from the label on the interconnect cable;    setting the function of the data reader on the basis of the data obtained from the label.    
     
     
         2 . A method for setting a function of a data reader according to  claim 1  wherein the data reader comprises a handheld laser scanner.  
     
     
         3 . A method for setting a function of a data reader according to  claim 1  further comprising the step of ensuring a correct interconnect cable is selected for the given host device and the data reader.  
     
     
         4 . A method for setting a function of a data reader according to  claim 1  wherein the label comprises a bar code label and the data reader comprises a handheld bar code reader.  
     
     
         5 . A method for setting a function of a data reader according to  claim 1  wherein the label comprises a radio frequency identification tag and the data reader comprises a radio frequency identification reader.  
     
     
         6 . A handheld data reading device comprising a housing and a connector cable detachably connectable to the housing, the connector cable being changeable by connecting to and being disconnected from the body portion wherein an internal parameter of the scanner may be changed by changing the connector cable.
