message, most likely it means that you failed to configure your VXI
controller correctly.
If you added additional memory to your VXI controller without
reconfiguring your controller, you may receive this error. See the
sections, Configuring VXIpc-860, VXIpc-850, and VXIpc-740
Embedded Controllers and Configuring PCI-MXI-2 Controllers,
earlier in this document for the steps to configure your controller
when adding additional memory.
4. When I attempt to save my configuration in the NI-DAQ
Configuration Utility, I receive a dialog box that says The device
did not pass the test. What does this mean?
If you followed the steps in the Software Installation and
Configuration sections of these release notes and you get this
message, most likely it means that you failed to configure your VXI
controller correctly.
5. How do I know my VXI-DAQ module is installed and working?
After following the installation and configuration steps, run the
NI-DAQ Configuration Utility. After opening the program, click on
the entry for your VXI-DAQ module. When the second window
appears, click on the Test Resources button. If the device passes the
test, a message box will appear that states The device has passed the
test. The tests are interactive and test the A/D converter, the D/A
converter, the digital I/O lines, and the counter/timers. Additionally,
if you installed the VXIplug&play instrument driver, the soft front
panels included with the instrument driver are also useful in
verifying that your module is working.
6. What is meant by kernel mode access and what do I need to know
about it?
NI-DAQ handles all interrupts in kernel mode. However, old
versions of NI-VXI or NI-VISA can prevent NI-DAQ from
communicating with your VXI-DAQ module in kernel mode.
Furthermore, certain controllers do not provide all of the necessary
hardware support for kernel mode access. The following controllers
do NOT provide the necessary hardware support: AT-MXI-1,
AT-MXI-2, VXIpc-486 Model, 500 Series Embedded, GPIB-VXI,
and third-party controllers.
When NI-DAQ is denied kernel mode access, it is unable to perform
some buffered operations, such as waveform capture. It can still
perform immediate operations, such as
AI_VRead in
LabWindows/CVI, or AI Single Scan and timed, nonbuffered
