Setting Up The Usb-Com Interface - Denso QB30-SR User Manual

4.2.1

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.
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
Follow the procedure shown below to install the Active USB-COM port driver.
The driver installation procedure consists of two processes: installation of the serial port driver to be performed before
connection of the USB device (scanner) and installation of the USB driver to be performed following connection of the USB
device.
The driver installation procedure is required every time a USB device is to be connected to a difference USB port.
To use a new USB port for which the driver has not been installed, be sure to perform the driver installation procedure.
Installing the serial port driver before connection of the USB device
[Windows XP]
(1) Run the Setup.exe.
2) Wait for the InstallShield Wizard screen to appear and then click Next.
