6.2.4 Power Supply Replacement:
WARNING: See the Specifications section for information on the power supply
requirements. Use of a power supply with incorrect polarity, voltage, or other
ratings may cause safety hazards, void the user’s warranty or damage system
components.
The EyeLink CL camera requires a power supply that is rated for 12V and
2A or higher. This supply must have a 2.5mm coaxial (“barrel”) power connector
(5.5 × 2.5 × 9.5mm). For safety reasons, the power supply must have EN 60950,
UL 1950, CSA 22.2 No. 950, or other equivalent safety approval. The power
supply should also be labeled “Class 2” or “LPS” for compatibility with the latest
safety requirements. SR Research can provide replacements if required, or a list
of approved power supplies.
It is important to ensure that the power supply has a ferrite (the black ring
on the cable near the connector) in order to prevent electronic interference
being generated. If the new power supply does not have such a ferrite, this
should be moved from the old to the new cable, and clamped to the cable within
10 cm of the camera.
