Vernier EasyLink®
(Order Code EZ-LINK)
Vernier EasyLink is a single channel interface that plugs into the USB port of the TI-84 Plus, TI-84 Plus Silver Edition, TI-Nspire, or TI-Nspire CAS calculator. Vernier EasyLink’s flexibility and ease of use make it perfect for a variety of activities in science and math. It supports over 45 analog sensors, including Gas Pressure, pH, and Dual-Range Force, among others.
Using the Vernier EasyLink with TI-84 Plus and TI-84 Plus Silver Edition Graphing Calculators
Follow this general procedure when using Vernier EasyLink with the TI-84 Plus family of calculators.
1. Confirm that the EasyData pressing the applications. When you know that EasyData is there, press return to the home screen. If EasyData is not installed, see below.
2. Connect one of the compatible sensors (listed in the chart) to Vernier EasyLink.
3. Connect Vernier 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 Vernier 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. For more information about EasyData, visit our web site at www.vernier.com/easydata
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/easydata). Download the application to your computer and then use a 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.

Wide-Range Temperature Probe
This interface is equipped with circuitry that supports auto-ID. When used with the TI-84 Plus calculators or TI-Nspire handhelds or TI-Nspire, Logger Pro, or Logger Lite software on a computer*, the data-collection software identifies the interface and uses pre-defined parameters to configure an experiment appropriate to the recognized sensor. This greatly simplifies the setup procedure for many experiments.
Power Considerations
Vernier 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.

Troubleshooting Tips
LED remains red
When the software communicates with Vernier EasyLink, the LED on the Vernier EasyLink shows the status of the communications. Initially as they communicate, the LED is red, and then it turns to green when the communications have been established. If the status remains red, contact Vernier for additional help.
*
With the appropriate adapter (order code MINI-USB), Vernier EasyLink can also connect to
the USB port of a computer or LabQuest.
Vernier EasyLink not identified/LED remains off
If the LED is off while the data-collection software is running and your Vernier EasyLink is attached but not identified, select New from the File menu in the software. If this fails to resolve the problem, a fresh set of calculator batteries will probably solve the problem. If the problem persists, contact Vernier for additional support.
EasyData does not auto-launch
If your calculator contains the EasyData app and you have the calculator on the main screen, plugging Vernier EasyLink into the USB port on a TI-84 Plus calculator will cause the EasyData app to launch. This assumes that the calculator’s batteries are in good condition. If they are weak, you may see a message about a low-battery condition. If EasyData does not auto-launch, leave Vernier EasyLink attached to the calculator and start the EasyData app by choosing it from the Apps menu. If an error message appears, your batteries are probably too low. Using a fresh set of batteries will probably solve the problem.
Warranty
Vernier warrants this product to be free from defects in materials and workmanship for a period of five years from the date of shipment to the customer. This warranty does not cover damage to the product caused by abuse or improper use.
