Analog Card Wiring
2.4.5.2
The analog card allows position information and pupil size to be output as analog voltages. The
card connects to a breakout board using a thick cable, and the breakout board in turn has a
number of BNC connectors attached to it. Each BNC connector has a label. See Table 1 for
details of the information carried on each line.
To reduce noise it is recommended that the breakout board be encased in an RF shielded and
insulated box.
For detailed information regarding configuration and use of the analog card please see
Appendix A of the EyeLink 1000 User Manual.

2.4.6 Camera Lens Selection

The EyeLink 1000 Mounts come with a number of different lenses to be used for unique eye
tracking situations. Table 2 lists recommended lenses for a range of eye-to-camera distances as
a function of the type of mount being used.
In all cases, eye-to-camera distance is listed in cm and measured from the surface that the lens
screws into (on the Standard Camera or the Fiber Optic Camera Head) to the bridge of the
participant's nose.
