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.
