EyeLink 1000 Host Software v 4.594

Host software for the EyeLink 1000. This version is compatible with the following mounts (using either a Standard or Fiber Optic camera):
  • Desktop (including Remote setup)
  • Tower
  • LCD Arm
  • Long Range Fiber Optic
  • Primate


⚠️ Important: Before You Begin
  • Be sure to back up your existing host elcl directory before proceeding.
  • Make note of any custom changes you have made to your .INI files. You may need to re-apply them after the update.


  1. Download and Preparation
    • On a separate, internet-connected computer, download the correct software version.
      • Choosing the Correct Version:
        • Desktop Mount:
          • If the illuminator is on the right side of the camera (when facing it), download the Right version.
          • If the illuminator is on the left side of the camera, download the Left version.
        • Arm Mount:
          • Download the Right version.
        • Tower / Primate / Long Range Mount:
          • You may download either the Left or Right version.
      • Download Links:
    • Save the downloaded .zip file (e.g., elcl_4.594_right.zip) to a USB drive.
  2. Installation Steps
    • Reboot the EyeLink Host PC. When prompted, select Windows (not EyeLink).
    • In Windows, navigate to the EYELINK partition (this is usually the D: or E: drive).
    • Find the existing ELCL folder and rename it to elcl_old and . (This is your backup).
    • Plug in the USB drive containing the new software.
    • Copy the .zip file from the USB drive to the Host PC's desktop.
    • Extract the zipped file. This will create a new ELCL folder.
    • Move this new ELCL folder to the root of the EYELINK partition (E: ).
    • Verify that your E: drive now contains both the new ELCL folder and your backup, elcl_old.
  3. Restore Previous Configuration
    • Navigate to your backup folder: E:\elcl_old\EXE.
    • Find and copy the file with the .scd extension.
    • Paste this .scd file into the new folder: E:\ELCL\EXE.
    • Go back to the E:\elcl_old\EXE folder.
    • Copy the files PHYSICAL.INI and FINAL.INI.
      • (Optional) If you use a USB keyboard:
      • Go to the new E:\ELCL\EXE folder.
      • Find the file elcl.usb and rename it to ELCL.INI.
    • Paste these two files into the new E:\ELCL\EXE folder. If Windows asks, choose to Replace the existing files.
    • Cut and paste E:\elcl_old\ from the EyeLink partition to your Windows desktop to free up space.
  4. Finalize
    • Unplug the USB drive. (This is important, as it can interfere with the host software).
    • Shut down Windows and reboot the Host PC.
Notes:
In general, USB keyboards or mice should not be used with recent Host PC models (Dell Optiplex 755 / 760, Precision 390 / 490 / T4300, or the custom-made Host PC) due to potential interference with tracker performance.
