Hi,
I am trying to change some parameters of my Simulink model with
Simulation Interface Toolkit. The problem is that I cant acced to all
of them. For example, I want to change a cut-off frequency. When I
enter the SIT Connection manager, a path is given so that I can
change that parameter. But
Dear LVers,
This is probably an easy one but password discussion on the list made
me wonder how to change my passwords for RT targets from LabVIEW 7.0

should. At least there is no danger in forgetting it this way tough.
Does anybody have experience on data acquisition using ADLink DAQ2204
card under LabVIEW 7.0 environment. It would be very grateful if you
can direct me to some example programs.Thanks a lot!

I am considering porting my VIs to Linux (RedHat 7.3).

Linux version to yield similar performances?
Thanks
The base version is just as the name implies. You would be better off
if you chose the full developemet edition of labview 7.1(current
version) This will give you all the functionality of the base version
plus a lot more features. Some you may not need NOW but will become

LabVIEW 7.0 does not work for Linux kernel 2.6.
Linux kernel 2.6 is now supported, using LabVIEW 7.1 for Linux.
