Common Questions
© National Instruments Corporation
This appendix answers common questions you may have when using the
VXIpc 700 Series.
What do the LEDs on the front of the VXIpc-700 mean?
Refer to Appendix C,
LEDs.
Is something wrong with the VXIpc-700 if the red SYSFAIL and
FAILED LEDs stay lit after booting the VXIpc-700?
If either the SYSFAIL or FAILED LED remains lit, refer to Appendix C,
LED Indicators, for troubleshooting steps.
Can I access 32-bit registers in my VXIbus system from the
VXIpc-700?
Yes. The VXIpc-700 uses the 32-bit PCI bus to interface to the VXIbus. In
fact, the VXIbus circuitry on the VXIpc-700 also supports the new VME64
standard for D64 accesses. Refer to your VXI software manual for more
information.
What is the accuracy of the CLK10 signal?
The CLK10 signal generated by the VXIpc-700 is ±100 ppm (0.01%) as per
the VXIbus specification.
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.
