Always keep this manual nearby for speedy reference. Strict observance of these warnings and cautions is a MUST for preventing accidents that could result in bodily injury and substantial property damage.
  • Page 8 To System Designers: • When introducing the QK20 series of scanners in those systems that could affect human lives (e.g., medicines management system), develop applications carefully through redundancy and safety design which avoids the feasibility of affecting human lives even if a data error occurs. Wrong handling of the scanner could result in a heat, smoke, or scanner failure.
  • Page 9 Wrong handling of the scanner could result in a heat, smoke, or scanner failure. Be sure to observe the following. • Never disassemble or modify the scanner. Doing so could result in a fire or electrical shock. Never disassemble • Do not put the scanner on an unstable or inclined plane. The scanner may drop, creating injuries.
  • Page 10 Wrong handling of the scanner could result in a heat, smoke, or scanner failure.

  • Page 15: Qk20-U

    QK20-U The QK20-U receives and sends data from/to the host computer through the USB-COM interface or USB keyboard interface. You need to set up the device driver designed for the interface to be used. Notes for connecting the USB interface cable To use the USB-COM interface, you need to install the serial port driver to the host computer before connection of the USB interface cable.

  • Page 16: Setting Up The Usb-Com Interface

    The driver always serves as a virtual serial port even if a USB device is unplugged, so the driver always occupies a COM port number. The driver cannot coexist with conventional Denso USB-COM device drivers in a host computer. In the installation procedure, the Active USB-COM port driver requires uninstalling the conventional ones.
  • Page 17 (3) Check that the USB device (scanner) to be connected is not plugged in the computer, and then click OK. Note: When installing the serial port driver for the 2nd or the following USB devices on the same computer, check that none of those USB devices is plugged in the computer, and then click OK.
  • Page 18 (5) Wait for the caution message for driver's digital signature to appear, then click Continue Anyway to proceed. (6) After completion of installation of the driver files, click Finish. Windows 7 (1) Run the Setup.exe. (2) Wait for the user account control massage window to appear, then click Yes. (3) Wait for the InstallShield Wizard screen to appear and then click Next.
  • Page 19 (5) Wait for installation of the driver files to proceed. (6) After completion of installation of the driver files, click Finish. • To use two or more USB ports To use two or more USB ports, run the Setup.exe by the same number of times as the number of USB ports to be used. Running the Setup.exe once adds one COM port.

    Appendix 2 Control Commands Control commands refer to commands that are exchanged between the host computer and the scanner via the communications line. Some of the control commands that the host computer issues are functionally equivalent to some parameters that can be set with the QR-coded parameter menu (refer to Chapter 11).
