Vernier EasyLink User Manual

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.

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.
