11. How do I use SCXI with my VXI-MIO module?
Simply follow the procedures outlined in your NI-DAQ
documentation for MIO E Series devices. Using SCXI with your
VXI-MIO module is no different than using SCXI with any other
MIO E Series device.
12. Are there any module features described in my VXI-DAQ user
manuals that may not be supported in NI-DAQ?
For the VXI-DIO-128 and the VXI-AO-48XDC modules,
NI-DAQ 5.1 does not support Serial Number EPROM or
Temperature Sensor features.
13. When I attempt to use the regeneration modes for waveform
generation, why do I receive the -10004 (valueConflictError)
error?
Waveform regeneration modes (regeneration mode values 2 and 3
in the AO Buffer Write VI in LabVIEW and oldDataStop value 1
and partialTransferStop value 1 in
WFM_DB_Config) are supported
on the VXI-MIO modules only when you use interrupts to send the
waveform data to the module. Since the default transfer mode for
waveform generation uses DMA, use the Set DAQ Device
Information VI in LabVIEW or the
Set_DAQ_Device_Info
function in the C language interface to switch to using interrupts.
Also notice that if kernel mode access is denied, the regeneration
modes will never be available, since you can only use DMA in this
case.
14. I am using an embedded controller and when I attempt to test
the resources, the NI-DAQ Configuration Utility stops
responding. What is wrong?
The address map for your controller might be incorrect. Run
RESMAN
and note the amount of memory requested by your controller. If the
amount of memory requested does not match the actual amount of
memory in the embedded controller, you need to reconfigure your
controller.
a. Launch
VXIEDIT.
b. Choose VXIpc Configuration Editor.
c. Choose Logical Address Configuration Editor.
d. Change the VXI Shared Ram Size to the amount of RAM in
the controller.
e. Click on OK.
