 QK11-U USB Driver Installation

This scanner can communicate with PC via the USB-COM interface.
Install the USB device driver contained in the provided CD-ROM for communications via
USB-COM interface: You can also download the newest version of this driver from
DENSO WAVE website:

http://www.denso-wave.com/

The downloaded, compressed file contains the driver and uninstaller. Store the file in the
desired folder, and double-click the file icon: The file can then be self-extracted.
Connect the scanner interface cable to the USB port of PC: “Add New Hardware
Wizard” will automatically start. Set up the USB device driver according to the wizard
screen.
The next and subsequent pages will show the procedures for setting up the driver on
each OS: Windows 98SE, Me, 2000 or XP.

 Cautions when connecting USB cable

• It will take five to ten seconds for PC to recognize USB-COM device:

Therefore, wait for ten seconds or more to disconnect or connect USB-COM
connector again after the connector is connected or disconnected.

• USB connector can be connected or disconnected even when the power of PC is ON.

However, do not connect or disconnect USB connector when PC is in the standby
(suspended) mode.

• Do not connect or disconnect any other USB devices while processing connection of

our USB device.

• If USB cable is disconnected during communication, not only will data be lost but the

system may be affected. Therefore, do not disconnect USB cable during
communication.

• Directly connect QK11-U to USB port of PC or self-power hub. If it cannot be

connected to hub (depending on type of hub) and operation is not stable, connect it
directly to USB port of PC.

 Cautions when installing USB device driver

• If the DENSO WAVE USB-COM driver has not yet been installed, do not connect

QK11-U to USB port of PC when turning PC on: Since installation of USB driver starts
during startup of Windows, the installation will not proceed properly.

• If you are already using our USB-COM products with our USB-COM driver, the

USB-COM driver installed can be used for QK11-U, and new installation is not
necessary.
If you want to install a new driver, use the designated uninstaller to uninstall the
previously installed driver.

Chapter 2. How to read

 Scanning Codes

Turn power on: The QK11-U will be ready for scanning. In this status, bring the LCD of a
mobile phone near the scanning window as shown in the figure below. The QK11-U will
read codes, output the data, sound buzzer and cause the OK LED to light.

• Reading may be impossible depending on the mobile phone model, setting status of

contrast and backlight, or the condition of LCD surface (pasting of seal, scratches,
etc.).

By command control, QK11-U is ready for scanning, it can change into a standby state
or a reading code can be set up.
Please refer to 3. Communications about the method of command control.

Re-read prevention

The QK11-U supports the re-read prevention function, so that if a code fits on the
scanning window, it will not read the same code multiple times in succession. Therefore,
if you want the QK11-U to read the same code again, separate the code from the
scanning window for at least one second to release the re-read prevention function.
However, if you fit a low-quality code that cannot be read for more than one second on
the window, the QK11-U can re-read the code at an interval of one second or more.

15

Chapter 3 Communications

QK11-U employs USB1.1 standard to integrate virtual COM port driver special for
computers. All communication software based on serial port formerly could use this
product. You may set various communications conditions by scanning QR-coded

Chapter 5 QR-coded Parameter Menu

The QR-coded parameter menu allows you to change a variety of functions built in the
QK11-U according to the procedure below.

Parameter change procedure

(1) Make the QK11-U ready for scan.
(2) Scan the "Start setting" code in the menu control shown on the next page.
(3) Scan a QR code(s) of the parameter(s) you want to set.
(4) Scan the "End setting" code in the menu control.

This stores new settings in the memory and completes the parameter change
procedure. The QK11-U will become ready to scan. If you turn off the power, those
new settings will be retained.

NOTE: If you turn off the power without scanning the "End setting" code, new

settings you made will be canceled.

To restore factory defaults, scan the "Defaults" code in the menu control.

To cancel the parameter change procedure, scan the "Cancel" code.
