INFORMATION FOR THE USER
This device complies with part
15 of FCC rules. Operation is subject to the following
two conditions: (
1) This device may not cause harmful interference, and (2) This device
must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a CLASS B
digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions contained in this data sheet, may
cause harmful interference to radio and television communications. However, there is
no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
* reorient or relocate the receiving antenna
* increase the separation between the equipment and the receiver
* connect the equipment into an outlet on a circuit different from that of the receiver
* consult the dealer or an experienced audio television technician.
Note: Connecting this device to peripheral devices that do not comply with CLASS B
requirements or using an unshielded peripheral data cable could also result in
harmful interference to radio or television reception. The user is cautioned
that any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment. To ensure
that the use of this product does not contribute to interference, it is necessary to use
shielded I/O cables.
Warning:
Electrostatic discharge (ESD) can damage several
components on the board. To avoid such damage in
handling the board, take the following precautions:
Bring the card and everything that contacts it to ground
potential by providing a conductive surface and
discharge paths. As a minimum, observe these
precautions:
• Disconnect all power and signal sources.
• Place the card on a grounded conductive work surface.
• Ground yourself via a grounding wrist strap or by holding a
grounded object.
• Ground any tool that will contact the card.

HARDWARE INSTALLATION
Note: The card has to be installed in the computer prior to installing its
driver.
Installing the card
Gently plug the card in a free PCI slot and press it down to position it firmly.
Tighten the screw.
Interrupt and memory address
Hardware interrupt and addresses are automatically set up at start-up by the
PCI PnP BIOS.
WARNING
This card includes a microphone pre-amplifier, which is sensitive to electro-
magnetic perturbations.
In order to avoid spurious noise when using the microphone input, we
recommend not to install the VX222-Mic next to another card that has a fan
(video card for instance). If this cannot be avoided, try to have some free slots
between the two cards.

SOFTWARE INSTALLATION
Please visit the Digigram web site at www.digigram.com for the most recent
driver.
In case you run a specific application developed or installed by a Digigram
Partner, this application might require the use of a specific driver version. In
this case, make sure that the updated driver has been approved by your
supplier.
The default driver is DirectSound.
In addition, a Wave driver is available, its installation is optional.
Installation under Windows 2000, XP, and
Windows Server 2003
• First insert the card in the computer.
• Restart the computer. Windows Plug and Play wizard will detect it and
request a driver.
• Click on Cancel to close the Windows Plug and Play Wizard.
• If you have downloaded the driver package from the web site, run the
self-extractible file. Select the temporary location where Setup will
expand the files, and click on Start. Click on Ok in the 'Finished'
window. The installation program is then automatically started.
• Otherwise browse to the installation folder and double-click on
'setup.exe'.
• Click on Next.
• Read the License agreement and click on Yes to confirm.
• Select the components to install. Select Wave if you want to install the
Wave driver in addition to the DirectSound driver. Click on Next.
• Under XP, select Continue anyway when the following message is
displayed:
”The software has not passed Windows Logo testing”.
If you have chosen to install the Wave driver, this message will appear a
second time. Select again Continue anyway.
• Click on Finish.
Removing the VX driver under Windows 2000, XP,
and Windows Server 2003
• Go to <Start> <Settings> <Control panel> <Add/Remove Programs>.
• Select the ‘Digigram VX Kit …’ and remove it.
• Follow the instructions of the InstallShield wizard.

Updating the VX driver under Windows 2000, XP, and
Windows Server 2003
• Remove the driver as described above.
• Run the installation program of the new driver, as described above.
Note: If you have done an installation without selecting the Wave driver,
and want to install it now, it is necessary to remove the installed
(DirectSound) driver, and then re-install it.
HOW TO CHECK THE INSTALLATION
Once the driver and the cards are installed according to the procedure
described in this manual, you can verify that the card is properly installed and
works fine as follows:
Go to <Start> <Programs> <Digigram> and select Digigram
Control Center.
In the Digigram drivers window, select the General Information
tab.
In the Modules Information window the installed VX Kit modules
are displayed along with their versions.
In the Digigram drivers window, select the VX Setup tab for a list
oft he installed cards. Each card is represented by an icon.
Click on the Windows Multimedia properties button to open the
'Sound & Multimedia properties' window. Select the Audio tab.
The card devices are listed:
VX222-Mic Out #1 in Sound playback, preferred device.
This is a Wave device.
VX222-Mic In #1 in Sound recording, preferred device.
This is a Wave device.
VX222-Mic Audio Card (WDM) in both playback and recording,
preferred device. This is a DirectSound device.
In case the card is not displayed:
make sure that the card is correctly inserted in the PCI slot, and
screwed on the PC chassis.
if necessary, uninstall the VX Kit package as described above and re-
install it.
