If an experiment is open on the Display PC (like TRACK.EXE) then pressing the
ENTER key from the Setup screen (or click on the “Image to Display” button)
will start displaying an image of the selected camera view on the Display PC’s
monitor. In the Setup screen, you can select one of the camera views to be
active (and transferred to the Display PC, if an image is currently being
transferred) by pressing the

3.2 Participant Setup
To practice setting up the camera, you will need a participant. If none is
available, you can practice this part of the procedure on yourself. It may be
easier to practice on yourself first, but be sure to repeat with several
participants later. Because all keys on the Display PC keyboard are sent to the
EyeLink software by TRACK, you can practice calibration and observe your
tracked eye-position too. Since no menus appear on the Display PC, you will
need to be able to see the Host PC display as well.
NOTE: It is recommended that the Host PC be switched on, and software
started, at least 10 minutes before tests or operation as a diagnostic system. It
is likely that the illuminator brightness and camera image quality may change
slightly during the warm-up period.
The EyeLink Portable Duo supports two operational modes – head-stabilized
mode, and remote mode.
