\section{Importing Data from a TI-82 Graphing Calculator}

You can import data to \textsl{Scientific Notebook }from your TI-82\
graphing calculator. Once you've imported the lists, vectors, matrices or
numbers from your calculator, you can use them in computations just like any
other \textsl{Scientific Notebook }data.

You can also import data from these models of TI graphing calculators:

\begin{itemize}
\item  \hyperref{TI-83}{}{}{TI83_calculators.tex}

\item  \hyperref{TI-85}{}{}{TI85_calculators.tex}

\item  \hyperref{TI-92}{}{}{TI92_calculators.tex}\medskip 
\end{itemize}

\subsection{\ What You Need}

To import data from your calculator, you need TI-GRAPH LINK$^{\text{TM}}$
for Windows$^{\text{TM}}$ software for TI-82 calculators, as well as certain
other \hyperref{computer hardware and software}{}{}{TI_calculators.tex#What
you need}.\medskip

\subsection{\ How to Import Data}

After you've installed the TI-GRAPH LINK$^{\text{TM}}$ software on your
computer, you can import data by following the instructions in the three
major steps below:

\begin{enumerate}
\item  Use the communications software to move the data from your calculator
to your computer.

\item  Use the communications software to export the data to an ASCII text
file.

\item  Use \textsl{Scientific Notebook }to read the ASCII text file into a
document.\medskip 
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To move the data to your computer}

\begin{enumerate}
\item  Connect your TI-82 calculator to your computer with the TI-GRAPH LINK$%
^{\text{TM}}$ cable.

\item  Turn on your calculator.

\item  On your computer, start TI-GRAPH LINK$^{\text{TM}}.$

\begin{enumerate}
\item  Open the Link menu.

\item  Open the Receive menu.

\item  Select Individual Files.

\item  When the Receive window opens, choose Directory and select the
directory where you want to save the TI files.

\item  Choose OK.
\end{enumerate}

\item  On your calculator, press \lbrack 2nd\rbrack\ \lbrack LINK\rbrack .

\begin{enumerate}
\item  Select \TEXTsymbol{<}SelectAll-\TEXTsymbol{>} to display all TI-82
items.

\item  Use the up and down arrows to move from item to item, and press
\lbrack ENTER\rbrack\ to mark each item you want to send to the computer.

\item  Select \TEXTsymbol{<}TRANSMIT\TEXTsymbol{>}.
\end{enumerate}

\item  In the Received window displayed on your computer screen, click Save
to save the files to the selected directory, or click Cancel to exit without
saving.

\item  If an incoming item has the same name as an existing computer file, a
Warning! window opens with four choices. Choose one:

\begin{itemize}
\item  overwrite the existing file

\item  rename the incoming item

\item  skip to the next item

\item  quit (cancel) without receiving any more items.\medskip
\end{itemize}
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To export the data to an ASCII\
text file}

You must export program files one at a time.\vspace*{1pt}

\begin{enumerate}
\item  In TI-GRAPH LINK$^{\text{TM}}$, open the File menu, open the File
Utilities submenu and select Export Program.

The Export Program window opens.

\item  Select the program file that you want to export and choose OK.

The Save As dialog box opens and shows the original filename with the
extension .txt appended.

\item  Specify the directory and path for the exported file.

For example, type \textbf{\TEXTsymbol{\backslash}scinotebook\TEXTsymbol{%
\backslash}docs\TEXTsymbol{\backslash}mydata.txt}.

\item  Choose OK.

\item  Repeat steps 2--4 for all the files you want to export.

\item  When you have exported all the files, press Esc to return to the main
menu.\medskip
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To read the ASCII\ text file into
a Scientific Notebook document}

\begin{enumerate}
\item  In \textsl{Scientific Notebook,} place the insertion point at the
place in your document where you want to import the data.

\item  From the File menu, choose \hyperref{Import Contents}{}{}{%
Import_contents.tex}.

\item  In the Files of type box, select TI Files.

\item  Specify the location of your exported file and select the file

\item  Choose OK.

The \textsl{Scientific Notebook }import filter reads the ASCII data file and
converts it to a value, list or matrix. The program imports the data at the
insertion point.\medskip
\end{enumerate}

\subsection{\ Troubleshooting}

You can obtain troubleshooting \hyperref{assistance}{}{}{%
TI_calculators.tex#Troubleshooting} if you experience problems importing
data from your calculator.\medskip
