TI Connect Software for the TI-84 Plus

You need two things to enable your TI-84 Plus calculator to communicate with your computer: TI Connect (software) and a TI-Graph Link cable. TI Connect is free; the TI-Graph Link cable came bundled with your calculator. If you are no longer in possession of the link cable, you can purchase one at the Texas Instruments online store.

How to download TI Connect

The TI Connect software is on the TI Resource CD that most likely came with your calculator. However, the version on this CD may not be current. The following steps tell you how to download the current version of TI Connect from the Texas Instruments website:

  1. Go to the Texas Instruments website.

  2. In the Know What You’re Looking For? drop-down list, select TI Connect.

  3. Click the Downloads link in the column to the left of the page.

  4. Click either the Download TI Connect for Windows link or the Download TI Connect for Macintosh link (depending on the type of computer you use, Windows or Macintosh).

  5. If you haven’t already logged onto the TI website, the Sign In page appears. If you’re already a member, enter your e-mail address and password; if you’re not a member, sign up — it’s free.

  6. Click the appropriate language.

  7. Follow the directions given during the downloading process. Make a note of the directory in which you save the download file.

How to install and run TI Connect

After you’ve downloaded TI Connect, you install it by double-clicking the downloaded TI Connect file you saved in your computer. Then follow the directions given by the installation program you just launched.

When you start the TI Connect program, you see the many subprograms it contains. To see what these subprograms are used for, click the HELP button in the lower-right corner of the screen.

Each of the subprograms housed in TI Connect have excellent Help menus that tell you exactly how to use the program.

How to connect the TI-84 Plus calculator and PC

You use the TI-Graph Link cable that came with your calculator to connect your calculator to your computer. If you don’t already have a TI-Graph Link cable, you can purchase one at the Texas Instruments online store.

The TI-84 Link cable that came with your calculator is a USB-to-USB cable. Because the ends of this cable are of different sizes, it’s easy to figure out how to connect your calculator to your computer; the small end fits in the right slot on the top of your calculator and the other end plugs into one of your computer’s USB ports.

The TI-83 I/O-to-USB can be used to connect your calculator to your computer. The plug end of this cable fits into the top left slot on your calculator.
