2. Introduction
• One USB port is required for each installed device.
The USB port can be native to the PC or it can be a
USB port from an installed USB hub to the PC.
NOTE: The devices work with USB 1.1 or 2.0 ports,
but have a maximum USB data rate
of 12 Mbps.
• Surrounding Air Ambient Temperature: 32 to 158° F
(0 to 70° C).
3. Installation
• Insert the driver CD into your CD-ROM before
plugging the hardware into the PC.
• If you inserted the hardware first and the Found
New Hardware Wizard launched, click “Cancel” to
exit the wizard.
• After inserting the CD, the Black Box USB Driver
Installation wizard should launch automatically. The
following screen will appear for Windows 7 or 8.
A similar screen appears for other versions of
Windows.
If the installation wizard does not start automatically,
navigate to the CD-ROM drive. To find your CD-ROM
drive, double-click “Computer” or “My Computer” on
your desktop, then double-click on your CD-ROM
drive (usually D:). From the CD:
• On 32-bit Windows®, run D:\Windows\dpinst32.exe.
• On 64-bit Windows, run D:\Windows\dpinst64.exe.
• When the Black Box USB Driver Installation Wizard
appears, follow the wizard to complete the
installation.
• When the Black Box USB Driver Installation Wizard is
done installing the driver, use the included USB cable
to plug the USB hardware into an available USB port
on the PC.
4. Verify Installation
To verify that the installation was successful, open the
Windows Device Manager.
• Scroll down to Ports.
• Expand the ports by clicking on the plus sign (+).
This shows if the ports now exist on the PC.
• If there are no exclamation points or other indicators
of a problem, the ports should be installed correctly
and ready for use.
Verify with a loopback test.
• For RS-232, loopback pins 2 and 3. Use the pinout
chart for the location of each pin.
• Using Hyperterminal or a similar program, connect to
the appropriate COM port. Set the desired baud
rate. Make sure Hyperterminal local echo is OFF.
NOTE: Hyperterminal is not provided with Windows
Vista or 2003 Server.
