## Connecting and disconnecting TI graphing calculators

You can connect your TI graphing calculators to your computer using either of the following TI Connectivity Cables:

| • | USB Silver Edition cable

| • | USB computer cable (TI‑84 Plus Family and TI‑89 Titanium devices only)

You should connect your devices each time you start the TI Connect™ software, and then disconnect them when you finish. This helps the software to recognize which devices you are using.
