then tighten the knob. Click on the “Camera Position Detect” button on the

Camera Setup screen to check whether the correct eye is highlighted. If the eye

highlighted on the Camera Setup screen does not match the eye selection knob

position on the tracker device, you should ensure that the two illuminator

cables that come out of the left side of the Tower are connected properly to the

left side of the EyeLink 1000 high-speed camera: the cable marked with “R”

should be plugged to the port marked with an ‘R’ and the one with “L” to the

remaining port.

NOTE: Please check the height of the EyeLink 1000 Tower before having a

subject seated - ideally this should have the top of the display at about the

same height as the forehead rest. The Tower height adjustment should only

need to be done during initial system setup and not on a participant-to-

participant basis.

Before adjusting the camera image, check the mirror angle of the system. If the

subject does not wear glasses, set the mirror angle to the lowest position (i.e.,

loosen and move the mirror-angle adjusting knobs to a position away from the

subject and then tighten the knobs). This mirror angle will be compatible with

most of the subjects. On the Camera Setup screen, also uncheck the “Use

search limits” button. This allows the tracker to search for pupil position across

the whole camera image in case the pupil position is lost.
