Dear Reader,

The accompanying CD has three folders. The “VisSimComm” folder contains
the setup file for installing the simulation software VisSim/Comm 7.0 and the
setup file for installing the viewer-only version of the software. The “DAT”
folder contains files which are necessary for some simulations to run. The
folder “Simulations” contains all the simulation files used throughout the book.
It is further divided into eight sub-folders, each of them associated to one
chapter of the book. To use the supplied files, follow the instructions below.

The simulation software VisSim/Comm 7.0 can be installed by running the file
“setupVisSimCommWeb70.exe” inside the “VisSimComm” folder and following the
instructions during the installation process.

After installation VisSim/Comm will run in demo mode and will not let you save
your work. However, you can request license keys to enable a 60 day trial that
will let you save your work. A trial license can be obtained via e-mail by running
the VisSim license manager which is automatically installed when you install
VisSim, and clicking the “Email License Codes...” button. After receiving the
reply with the trial license keys, you must run the License Manager once more
and insert the trial license keys. Your trial will run 60 days before requiring
a permanent license. To purchase a permanent license, send an e-mail to
sales@vissol.com. For technical aspects, please write to support@vissol.com.

The simulation files supplied in the accompanying CD were implemented in a way that
you do not need a permanent license to run them. In fact, whether in demo mode or
running VisSim Viewer you will not miss any simulation detail explored throughout
the book.

After any of the working options of VisSim/Comm is enabled, create the folder “C:\DAT”
in your hard drive “C”. Copy the content of the DAT folder supplied in the CD to the DAT
folder you have just created. These DAT files are necessary for some experiments to run
and must not be created in another path different from C:\DAT, unless you modify all the
corresponding file paths in the simulation files. To do this, however, you will need a
full operating version of VisSim/Comm that lets you save your modifications.

Before you start running the simulations, it is strongly recommended that you become
familiar with the VisSim/Comm user interface. This can be easily accomplished through
the VisSim/Comm documentation installed in you computer with the software. Hint: The
zoom-in and zoom-out buttons located at the VisSim/Comm toolbars are of special value
when you open a simulation file so that it fits the screen of your computer if desired.

Now you are ready to run the experiments located in the CD, in the folder
“Simulations”, according to the guidelines given throughout the book. Each guideline
is identified by the word “Simulation” followed by its identification number according
to the chapter it refers to. As an example, Simulation 4.3 contains the guidelines of
the third simulation of the fourth chapter.

Good reading, good interaction with the simulation files, and good learning.
