The USB cable connector for your TI calculator enables you to add programs and tools to your computer's hard drive. You can also save formulas, problems and other data on your computer's hard drive for safekeeping.
Locate the USB port on your TI calculator. It is a small, rectangular hole found on the side of the calculator's body. Insert one end of the cable into the calculator's USB port.
Take the other end of the TI USB cable and insert it into one of the open USB ports on the side of your computer. Wait a few moments for your computer to recognize the calculator.
