Installation Instructions
To update the EyeLink3 Host software, please choose one of the two options below:
- Option 1: If you have a Display PC connected to the Host PC then the easiest way to update the software is on the Display PC side. Please follow the instructions below:
- Download the file called el3-7.50.68167-26-03-18-EyeLink3-x86_64.el3 that is attached to this post. If your Display PC is not connected to the internet then download the file on another computer, save the .el3 file on a USB memory device, and use the USB memory device to copy the file to the Display PC.
- Start up the Host PC. From the Host PC Application, press Ctrl-Alt-Q to exit the Host PC to the File Manager.
- Then, from your Display PC open a web browser (e.g., Chrome, Firefox, Internet Explorer, Safari, etc.). Type http://100.1.1.1 in the address bar and press Enter. This should allow you access to the Host PC's File Manager through your Display PC's browser.
- From your browser window on the Display PC that is showing the File Manager, click on the Configuration icon on the File Manager toolbar, and then select "System Update". Now choose the "Update" tab and click on the "Choose Files" button to locate the "el3-7.50.59361-24-11-13-EyeLink3-x86_64.el3" file and then click "Update".
- Wait until the host software is updated - please be patient as this process may take a few minutes to complete.
- Download the file called el3-7.50.68167-26-03-18-EyeLink3-x86_64.el3 that is attached to this post. If your Display PC is not connected to the internet then download the file on another computer, save the .el3 file on a USB memory device, and use the USB memory device to copy the file to the Display PC.
- Option 2: If you are using a stand-alone Host PC (i.e., your Host PC is not connected to a Display PC):
Please follow the instructions in the pdf attached below. If you are not using a stand-alone Host PC, then please follow the steps in Option 1 above -- the instructions below will work fine, but the process is simpler if following Option 1 above.
