===== General Setup =====

After the initial [[hardware:eyetracking:eyelink:install]], a Ethernet ((>=CAT5e, [[hardware:eyetracking:eyelink:connection]])) patch cable connects the Eye tracking PC to the "Eprime" Task computer. <wrap tip>See [[hardware:eyetracking:eyelink:taskpc_setup]] for details.</wrap>

  * Eye Tracking (Host) PC records eye data and <wrap alert>does **not** project to the participant facing projector</wrap>
  * EPrime (Display) PC controls everything and manages all participant facing displays
    * Connected to Host by blue ethernet/network/cat6 cable
    * displays calibration screen, talks to Host PC
    * sends triggers/messages to host pc during task (and potentially receives eye events from Host PC). See [[:hardware:eyetracking:eyelink:task_integration]].
  * Collected ''.edf'' files (gaze, pupil diameter, saccades, blinks) are saved from the Host PC and can be analysed offline. See [[:hardware:eyetracking:eyelink:analysis|EyeLink Analysis]].
