9.2 USB-COM Interface

This scanner is compliant with USB 1.1 (Universal Serial Bus Specification Revision 1.1).

Installing the dedicated Active USB-COM port driver to the host computer allows the USB-COM interface to

operate in communications applications using the conventional serial port.

Note: Entering data transferred from the scanner via the USB-COM interface directly to application (e.g., Access,

Excel, and Internet Explorer) running on the host computer requires the keyboard interface software(QR_kbif)*.

As shown below, the QR_kbif converts the data read into the keying format and passes it to applications in the

manner as if it is coming from the keyboard. It is, therefore, possible for applications capable of accepting keyed

data to handle the data read by the scanner.

* Registered users can download the keyboard interface software (QR_kbif) from QBdirect, their customer support section

on the Denso Wave website at no extra charge. For further details on QBdirect or to register, visit the following URL.

 Notes for use

• If you connect the scanner to your computer first time or have changed the COM port for the scanner or hub,

then confirm the COM port number on the Windows Device Manager or the like before use.

• If you want to use two or more communications processors (software) or scanners concurrently on your

computer, be sure to assign a unique COM port number to each of them.

• If the host computer switches to the suspend mode when any communications software is running and

recovers from that suspend mode, the software may freeze in some computers. Quit and restart the software.

• It is not necessary to make settings such as transmission speed, data bits, parity, and stop bits (which are

required for communications software using a conventional serial port) since the USB interface ignores those

settings. The flow control should be set to “Hardware (RTS/CTS)” or “None.”

• The virtual COM port on the computer and the scanner are connected with each other as shown below.
