indicate the type of processor used in the NI PXI-8102 controller,
the speed of the processor, and the number of processor cores.
Video Configuration Submenu
Use this submenu to apply alternate settings to the video configuration.
Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration possible.
•
Primary Display
—This setting specifies which video adapter the
BIOS should use as the primary adapter if more than one is present. To
use an external video adapter as the primary graphics adapter, choose
Add-in PCI Video
. The default value is
Onboard Video
.

system memory to allocate as graphics memory for use by the onboard
video device. The default value is

DDC Routing
—This setting determines how the monitor DDC is
routed. Use this setting to select whether or not the DDC is routed for
an analog monitor or a DVI monitor. In order to use a DVI monitor, this
setting must be set to
DVI
. An analog monitor, however, will function
with this option set to either
Analog
or
DVI
. The DDC communication
path is only enabled when set to
Analog
for an analog monitor, so
certain advanced features of your analog monitor may only be enabled
when routing DDC to
Analog
. The default setting is
DVI
.
USB Configuration Submenu

operating system such as DOS. The default value is
Enabled

Note
Certain real-time applications may require you to disable this setting to reduce loop
time jitter. When the controller is configured to boot LabVIEW RT, legacy USB support is
automatically disabled.
