Chapter 2 Preparation
2.1 Operating Environment for the Use of USB Interface
Using the scanner via the USB interface requires a host computer equipped with a USB port. The operating environment
differs depending upon whether you use the USB-COM interface or USB keyboard interface as listed below. (Plugging the
USB interface cable in the scanner automatically switches to the USB-COM interface by default.)
USB-COM interface:
(Default Setting)
To use this interface, you need to install the dedicated Active USB-COM port driver (virtual
COM port driver) to the host computer. This interface allows you to use the scanner in
applications using the conventional serial port. For instructions on how to set up the driver, refer
to Section 3.2.1. For the interface specifications, refer to Section 9.2.
USB keyboard interface:
No dedicated USB device driver is required. Via this interface, data scanned by the scanner can
be entered to the cursor position in your application. For instructions on how to set up the driver,
refer to Section 3.2.2. For the interface specifications, refer to Section 9.3.
To use the USB-COM interface (factory
default): To use the USB keyboard interface:
Host computer Windows machine
USB driver Active USB-COM port driver provided by
DENSO WAVE OS-supplied device driver
Note: For the compatible operating systems, see QBdirect.
The interface can be switched between the USB-COM interface and USB keyboard interface by using either the:
- Using QR-coded parameter menu (provided in Chapter 12),
- Using the configuration software (ScannerSetting_2D)*
If the Active USB-COM port driver is not installed in the computer, (1) connect the scanner’s USB interface cable to the
computer or its USB hub, and (2) press the trigger switch for more than two seconds.
However, this applies only when the USB-COM interface is set up, in which case the interface can be switched from the
USB-COM interface to the USB keyboard interface. Switching the interface vice versa is not supported.
The interface setting will be retained even if the scanner is turned off.
Note: For approx. 20 seconds after switching from the USB-COM interface to the USB keyboard interface, the
scanner cannot accept data entry.
*Registered users can download the configuration software (ScannerSetting_2D) from QBNet, their customer support section on the
Denso Wave website at no extra charge.

3.2 Using the USB Interface
The scanner 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 (see 3.2.1 and 3.2.2).
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.
When plugging and unplugging the USB connector, put an interval of at least 10 seconds between those actions since
Windows may take several to 10 seconds to add or delete the USB device.
Hot plugging/unplugging is allowed for USB devices. However, do not plug or unplug the USB connector when:
- The computer is on standby (in Suspend mode) or
When the host computer is processing the scanner connection, do not plug or unplug any other USB device cables.
Directly connect the scanner to the USB port on the host computer or to the self-powered hub. The scanner may not be
connected to some types of hubs. If the operation of the hub-connected scanner is unstable, connect it directly to any USB
port on the host computer.
Do not use any extension cord.

3.2.1 Setting up the USB-COM interface
Using the USB-COM interface requires installing the Active USB-COM port driver provided by DENSO WAVE to the host
computer. The driver does not come with the scanner in a CD-ROM. It can be downloaded for free from our website at:
http://www.qbdirect.net
The file downloaded contains the Active USB-COM port driver and uninstaller which are compressed. It is a self-extracting
file. Store the file into a folder and then double-click its icon to extract it.
For the latest information, refer to the manual that comes with the driver.
Notes for installing and using the Active USB-COM port driver
The driver should be installed with administrative permission (Administrator Login).
The driver does not contain a Microsoft digital signature. Therefore, do not block installation of drivers containing no
signature with the driver’s signature option or local policy’s security option.
The driver allows hot plugging or unplugging of a USB device even during communication (when the COM port is being
opened); however, the communications data when the USB device is disconnected will be lost.
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.
Installing the driver on a single host computer more than one time enables more than one USB device to be used. However,
the uninstaller of the Active USB-COM port driver uninstalls previously installed drivers, not individually but all at once.
Installation procedure
Refer to the installation procedure for “Active USB-COM Port Driver Installation Guide.”

7
3.2.2 Setting Up the USB Keyboard Interface
A USB class driver “HID (Human Interface Devices)”is used to communicate using the USB keyboard interface. This driver
is included in the Windows system files.
Note: If the scanner is set to the USB-COM interface, follow the procedures in Section 2.1 to switch to the USB keyboard
interface. (Factory settings: Set to USB-COM interface)
Connect the scanner USB interface cable to the USB port of the computer itself or USB hub.
For the following we will explain using examples from Windows 7, Windows 8, and Windows Vista procedures.
Windows 7, Windows 8, Windows Vista
(1) Turn on the computer and activate Windows 7, Windows 8 or Windows Vista, and log in as a user with administrator
privileges.
(2) Connect the USB interface cable of the scanner to the computer or USB hub.
(3) The message, “Installing device driver software” is displayed on
the taskbar at the lower right of the screen.
Scanner recognition will be automatic. Once the scanner has
been recognized the message will disappear.
(4) To check whether the USB device has been installed correctly,
go to the “Device Manager” screen.
If “USB input device” has been added under the “Human
Interface Devices” menu item, the scanner has been connected
correctly.
Reconnect the scanner if this item has not been added, or if a
or mark is displayed.

Chapter 4 Scanning Codes
(1) Bring the reading window to the target code and press the trigger switch. The marker indicating the approximate center
of the reading area irradiated by the illumination LEDs lights up for reading.
(This step is not required for the Continuous reading modes 1, 2, Auto sensing mode and Auto stand mode.)
(2) Wait for the indicator LED to turn blue and the beeper to sound, indicating a successfully read.
Note: The reading area is narrower than the irradiation area of the illumination light.
When the scanning distance is 9 cm, the reading area is approx. 9 x 6 cm.
Note: Note: Allow only a single code to come within the field of view except when the multi-line code scanning is
allowed. Having more than one code within the field of view either causes the read to fail or produces multiple
input.
Note: Note: The double-read prevention enabled time can be specified with the configuration software
(ScannerSetting_2D).
Note: The scanner can read codes omnidirectionally. Note that a target code plus its margin should lie within the
reading area.
Note: If the scanner fails to read due to specular effects or other factors, change the scanning angle of the reading
window or the distance from the codes, and repeat the process. (Specular effects occur when the reflection of the
light from the label surface is too strong, such as when the reflecting surface is polished or covered with vinyl.)
Scanning mode
Normal scanning mode This mode transfers the code data when the scanner has read the code successfully.
Data verification mode This mode verifies the code data against the master data stored in the scanner.

Chapter 5 Customizing the Scanner
You can customize the scanner by modifying communications, code type, and other scanner parameters with the QR-coded
parameter menu or the configuration software ScannerSetting_2D*. These parameters retain their settings even when the
power is off.
(1) Scanning parameter setting QR Codes from the QR-coded parameter menu by pressing the trigger switch.
(The QR-coded parameter menu is given in Chapter 12.)
(2) Using the configuration software (ScannerSetting_2D)*in your computer.
The configuration software is available via the RS-232C interface or USB-COM interface; it is not via the USB keyboard
interface. If the USB keyboard interface is set, the interface needs to be changed to the USB-COM interface. (In this case,
there is a need to change the interface to the USB-COM interface using the QR code menu and install the Active
USB-COM port driver provided by us. See Section 3.2.1.)
(The configuration software also offers batch-process QR code symbols for read by scanners in the field. Those symbols
printed can be scanned by the scanner via any of the RS-232C interface, USB-COM interface and USB keyboard
interface.
Note: The configuration software is not available via the USB keyboard interface.
*Registered users can download the configuration software (ScannerSetting_2D) from QBNet, their customer support section on the
Denso Wave website at no extra charge.

Chapter 6 Scanning Control
Two types of scanning controls are available--Trigger switch control and Software control. Trigger switch control: Pressing
the trigger switch readies the scanner for reading. (Refer to Section 6.1.)
Software control: Instead of pressing the trigger switch, you send control commands from the host computer via the RS-232C
or USB-COM interface to ready the scanner for reading or put the scanner on standby. (Refer to Section 6.2.)
In addition, the auto sensing mode and auto stand mode are also available. (Refer to Sections 6.3)
6.1 Trigger Switch Control
Pressing the trigger switch turns on the illumination LEDs and readies the scanner for reading. The scanner supports the
following six trigger switch operating modes. Select the one that best meets your needs using the QR-coded parameter menu
or the configuration software (ScannerSetting_2D).
(1) Auto off mode
When the trigger switch is pressed, the scanner is brought to the Active state for approximately 5 seconds.
The scanner automatically returns to the Ready state when reading is successfully completed, or after approximately five
seconds elapsed with the trigger switch pressed.
The scanner goes to the Ready state if the trigger switch is released before five seconds elapses.(in the case of normal mode)
When One Shot is set to the Auto off mode, you can set the duration of the Active state after the trigger switch is pressed.
(2) Momentary switching mode
The scanner is brought to the Active state only when the trigger switch is pressed, and returns to the Ready state when the
trigger switch is released.
(3) Momentary switching mode (Reverse type)
The scanner is brought to the Ready state only when the trigger switch is pressed, and returns to the Active state when the
trigger switch is released.
(4) Alternate switching mode
The scanner alternates between the Active state and the Ready state every time the trigger switch is pressed.
(5) Continuous reading mode 1
When you turn the scanner on, the scanner lights the illumination LEDs and becomes ready to scan. The scanner ignores all
trigger switch input. If the scanner receives the Z, READOFF or LOFF command, it switches to standby; if it receives the R,
READON or LON command, it becomes ready to scan.
You can select whether or not the scanner transmits the ERROR command when the scanner cannot complete reading and
switches to standby, using the configuration software (ScannerSetting_2D).
(6) Continuous reading mode 2
This mode is functionally equivalent to the Continuous Reading mode 1, except that the scanner waits for a command upon
completion of reading. To become ready to scan, the scanner should receive the Z, READOFF or LOFF command to switch
to standby and then receive the R, READON or LON command.
You can select whether or not the scanner transmits the ERROR command when the scanner cannot complete reading and
switches to standby, using the configuration software (ScannerSetting_2D).
Note: When you are setting parameters using the QR-coded parameter menu, the scanner is always in the Auto-off
mode regardless of the trigger switch operating mode selected.
