Head – note one of the power connectors is unused. Connect the fiber optic cable from the

that was provided with your system to the power connector on the Camera Base Box.

Adjusting the Desktop Mount (Monocular, Binocular and Remote
Recording)
Place the Desktop Mount on the table at a distance between 40 and 70 cm from where the
participant’s eyes will typically be, with the illuminator and eye camera facing the participant.
The recommended tracking distance is 50 to 55 cm. The camera screw of the Desktop Mount
should be aligned to the center of the display PC monitor and the top of the illuminator should
be as close to the lower edge of the visible part of the monitor to maximize the eye tracking
range.
If you are using the chin rest supplied by SR Research Ltd., please check whether the table is
suitable for mounting the chin rest – the table used should have a minimum thickness of 1.8
cm and a maximum thickness of 8.0 cm. Loosen the table clamp by turning the knob
counterclockwise, place the table clamp fully onto the table, and then tighten it clockwise.
Check that it is firmly secured by gently attempting to rock the table clamp base free. If the
table clamp base wobbles, tighten it further. Next, place the forehead rest over the chinrest
poles and tighten the knobs at the desired height.
Please check that the chinrest is horizontally centered with the monitor. Adjust the tilt of the
monitor so that the display is tilted up slightly. The tilt can be changed if there are any
reflection issues. Please follow “Section 8.4 Customizing Your PHYSICAL.INI Settings” to modify
the PHYSICAL.INI file settings.
