Common Questions
This appendix answers common questions you may have when using
the PXI-8150 Series embedded computer.
What do the LEDs on the front of the PXI-8150 mean?
Refer to Appendix C, LED Indicators, for a description of the front
panel LEDs.
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.
What type of video interface is onboard the PXI-8150? What video
drivers are included with the PXI-8150? Can I use Super VGA with
my PXI-8150? If my application requires a special type of video
display, how do I configure my PXI-8150?
The PXI-8150 uses the Cirrus Logic 5446 Series chip family, a
combination graphics accelerator and RAMDAC. The chips in this
family are compatible with the Standard VGA video output MS
Windows video driver, as well as the Cirrus Logic video driver.
For more information on the video driver, refer to the
c:\images\manuals
directory.
What kind of monitor can I use with the PXI-8150?
PXI-8150 computers that use Super VGA video output 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 damage
your monitor.
