Operating Environment for Use of the QK31-U

Using the QK31-U 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. The default interface is the
USB-COM interface.
USB-COM interface (factory default):
To use this interface, you need to install the dedicated Active USB-COM 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 device driver, refer to Chapter 3, Section 3.2.1. For the interface specifications, refer
to Chapter 9, 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 device driver, refer to Chapter 3, Section
3.2.2. For the interface specifications, refer to Chapter 9, Section 9.3.

Switching between the USB-COM interface and USB keyboard interface is possible by:
- Using QR-coded parameter menu (see Chapter 11),
- Using the configuration software (ScannerSetting_2D), or
- Using the Magic key (see Chapter 8.2).
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 our website QBdirect at no
extra charge.
