PCI-MIO-16XE-50 and Real-Time Windows Target


I am trying to get the PCI-MIO-16XE-50 card to work
with Real-Time Windows Target 2.1.

There are no problems the first 5-6 times when I
compile my Simlink model and execute the Real-Time
application. But then the Real-Time kernel seams to
have problems to connect to the PCI card as Windows NT
crashes with error code 0x0000001e which means that the
system couldn't read from the device.

Does anyone have any experience with this card and
various BIOS settings for the PCI bus. I think that
the problem has something to do with the PCI bus.

My system is:
Asus A7V133-c (BIOS 1007-001-G) Motherboard
Athlon Thunderbird 1200MHZ
512 MByte Infinion CL2
National-Instruments PCI-MIO-16XE-50

I've have a
clean Windows NT4 instalation with SP 6a.
I tried to compile the Real-Time application with
Visual C++ 6.0 and with Watcom 11.0c but there wasn't
any difference.

I would appreciate any hints and tips.

What driver are you using for the data acquisition board? Are you using an NI-DAQ driver from National Instruments, or are you using a driver from MathWorks?

If you are using an NI-DAQ driver from National Instruments, then visit for troubleshooting information. Even if you are not using the NI-DAQ driver, you may want to install it and use it at least to test the card.

If you are using a driver provided by Mathworks, please contact them for support.

Thank you very much for your answer. I installed
the NI-DAQ 6.9.1 driver from National-Instruments to
test the card. It was recognized and the ressource test
was ok. As I had only problems running it under
Real-Time Windows Target for a longer period I thought
there might be some problems with some PCI settings
in the BIOS.

A few hours ago I found out that the problem lies
in the driver supplied with Matlabs. The card works
without any problems under Matlab 5.3.1 (Real-Time
Windows Target 1.5) and Windows 98SE. I was running
it for some hours without a crash. For some
reason the newer driver supplied with Matlab 6.1
is making problems, as it is not possible to aquire
data from more than one chanel at the same time.

Anyway, I'm glad that th
e card is working without
problems and thanks again for your fast answer.
