Is there a bug in RTWT driver for NI PCI-6052E?
Jim Forrest
Workshop 4.1 and Real Time Windows Target 2.1.
I build a simple model which includes an analog input block and a
scope. I installed PCI 6052E, set Input range as -10 to 10V, Block
output as Volts. Then I run it in real time. The outcome of Real Time
Window Target(uses the driver from mathworks) is twice of that from
Labview or from board driver test panel provided by National
instrument. Is there anyone know the causes or is there a bug in PCI
6052E driver from mathworks?
Your reply will be greatly appreciated.

We had a similar problem with our PCI 6071E card. The default driver
included within matlab did not allow us to read all I/O channels
(Most probably the mdlSizes definitions within the mex file were not
correct). We wrote to Matlab Support and they sent us the correct
driver. So, try to get a new driver from matlab.

There of course may be a bug, as in any piece of software. What about
the other I/O ranges, e.g. -5 to 5V? Do they work properly or is there
also a problem? What about the Normalized bipolar mode? Does this work
as expected?
If Normalized bipolar works as expected, you may use that and multiply
the output by 10, at least for the meantime before we find out if it's a
bug in the driver or not.

Normalized bipolar and normalized unipolar work fine.
if I set the range as 0 to 10V, that also works fine.
any other settings (so far I tried) got twice results as they should
be.
Could you test it if you have PCI-6052E board. thanks
