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.

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 Chapter 3,

Section 3.2.2. For the interface specifications, refer to Chapter 9, Section 9.3.

This interface is selected by default.

USB-COM interface:

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 Chapter 3, Section 3.2.1. For

the interface specifications, refer to Chapter 9, Section 9.2.

To use the USB-COM interface: To use the USB keyboard interface

(factory default):

PC/AT or AT/AT compatible PC equipped with a USB port

Operating System (OS) Windows XP, x32 Edition

OS-supplied device driver

Note: The scanner cannot be used on Windows NT that does not support any USB device.

Switching between the USB-COM interface and USB keyboard interface is possible by:

- Using bar coded parameter menu (provided in Chapter 11),

- Using the configuration software (Scanner Setting),* or

- Connecting the scanner’s USB interface cable to the host computer or USB hub with the trigger switch

being held down. (If the USB-COM interface has been set up, doing so switches to the USB keyboard

interface, and vice versa.) (Interface switching when power turned ON is disable by default)

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 (Scanner Setting) from QBdirect, their customer

support section on the Denso Wave website at no extra charge.
