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.
