this decoder build-in scanner comes in one model and supports interfaces such as keyboard wedge, rs232 serial wedge, wand emulation, and the latest usb interface. in most of the cases, simply selecting an appropriate cable with a device code will work for a specific interface.

    interface selection: you can change factory interface default for other type interface. by plugging different cables, setting right interface, then the scanner will be changed to another interface. however, you must make sure which cable you need.

    keyboard/rs232/ubs auto detection: by setting this function, it will automatically select the keyboard wedge or rs-232 or ubs interface for user.
