Vernier EasyLink EZ-LINK Quick Start Manual

Vernier EasyLink
(Order Code EZ-LINK)
EasyLink is a single channel interface that plugs into the USB port of the TI-84 Plus
or TI-84 Plus Silver Edition calculator. EasyLink's flexibility and ease of use make
it perfect for a variety of activities in science and math. It supports over 30 analog
sensors, including Gas Pressure, pH, and Dual-Range Force, among others. (A
complete list of compatible sensors appears on the next page.)
Using the Vernier EasyLink with TI-84 Plus and TI-84 Plus Silver
Edition Graphing Calculators
Follow this general procedure when using the EasyLink with the TI-84 Plus family
of calculators.
1. Confirm that the EasyData application is installed on the calculator. Do that by
pressing the button and scrolling through the alphabetical list of
applications. When you know that EasyData is there, press
return to the home screen. If EasyData is not installed, refer to the Obtaining
EasyData section.
2. Connect one of the compatible sensors (listed in the chart) to EasyLink.
3. Connect EasyLink to the USB port on the calculator. The calculator will
automatically launch EasyData and detect the sensor.
4. You are now ready to collect data.
Data collection with EasyLink and the EasyData application is simple, yet powerful.
EasyData supports numerous data-collection modes, and EasyData version 2.0 or
newer has built-in analysis tools, such as linear regression, and statistical analysis.

Power Considerations

EasyLink draws its power and the power for the sensor from the calculator battery.
Both of these power draws will affect the calculator battery lifetime. With average
use of most sensors, your calculator batteries should last a semester. Of course
battery life will be determined by the amount of use and the type of sensor.

Obtaining EasyData

If EasyData is not installed on your TI-84 Plus calculator, you will need to install the
application onto your calculator. EasyData can be downloaded free from our web
site (www.vernier.com/easy/easydata.html). Download the application to your
computer and then use a
TI-Connectivity™
the application from the computer to the calculator. Your calculator will also need
operating system version 2.30 or newer. If necessary, download the operating system
from the TI web site (education.ti.com) and install it on your calculator.
