Setting Up The Usb-Com Interface - Denso AT20B-SM User Manual

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."
