Appendix F Common Questions
VXIpc 800 Series User Manual F-2 © National Instruments Corporation
If I boot the computer without video, and then plug in the video,
why is it in black and white?
When the computer first boots, the video chips try to synchronize with
the monitor. If the monitor is not there, the video chips cannot
synchronize and establish color. You need to have the monitor attached
at boot time to get color.
I’ve installed the SCSI software. Why doesn’t the VXIpc 800 Series
recognize my SCSI device?
This problem usually occurs when SCSI has not been enabled in the
BIOS. Enter your BIOS by pressing <DEL> at boot time. In the Setup
window, click on the Chipset icon. Select the On Board PCI SCSI
option and enable it.
What type of video interface is onboard the VXIpc 800? What video
drivers are included with the VXIpc 800? Can I use Super VGA
with my VXIpc 800? If my application requires a special type of
video display, how do I configure my VXIpc 800?
The VXIpc 800 uses the Trident Microsystems TGUI96
xx
chip family,
a combination graphics accelerator and RAMDAC. The TGUI9660 is
the first chip used from this family. Subsequent pin-compatible chips
will follow. The chips in this family are compatible with the Standard
VGA video output MS Windows video driver, as well as the Trident
Microsystems video driver. For more information on the video driver,
refer to the
c:\images\manuals directory.
If your application requires a special type of video display, you can
remove the PCI video card included with your VXIpc 800 Series.
Contact National Instruments for information on how to do this.
What kind of monitor can I use with the VXIpc 800?
VXIpc 800 computers that use Super VGA video output will work only
with monitors having a horizontal scan rate of at least 50 kHz and a
vertical scan rate of 60 Hz.
Caution: Make sure that your monitor meets this specification. Enabling the Super
VGA option on a monitor that does not meet this specification will cause
damage to your monitor.
