Check 1

First make sure that the Eye tracker is not connected through a USB extension cable, these can slow down data rate and cause connectivity issues, if your Tobii Eye Tracker is connected through an extension cable, please remove the extension and connect the Eye Tracker directly to the computer.


If you have an X2-60 please ensure that the Eye Tracker is directly plugged into the “External Processing Unit” directly through USB, that the “External Processing Unit” is powered and the Ethernet cable is connected to the “External Processing Unit” at one end and the computer at the other.

You may be using a Trendnet LAN to USB adapter supplied by Tobii to connect your Eye Tracker, although Tobii supplies these adaoters, we would prefer that you try not to use adapters at all and use the original cable type where possible. If you do need to use a LAN to USB adapter, we recommend that you plug your internet into the adapter and plug the eye tracker into the ethernet port, if you are using an adapter, please remove it and connect the eye tracker using the original cable types to check if there is an issue.
