3.5 mm captive screw connectors. If the USB port of a connected PC or laptop is capable
of providing USB power, an external supply for the transmitter is not required.
ATTENTIONS: • Always use a power supply supplied by or specified by Extron for use
with the FOX USB Extender Series. Use of an unauthorized power
supply voids all regulatory compliance certification and may cause
damage to the supply and the FOX USB Extenders.
• Unless otherwise stated, the AC/DC adapters are not suitable for
use in air handling spaces or in wall cavities. The power supply is
to be located within the same vicinity as the Extron AV processing
equipment in an ordinary location, Pollution Degree 2, secured to
the equipment rack within the dedicated closet, podium or desk.
• The installation must always be in accordance with applicable
provisions of National Electrical Code ANSI/NFPA 70, article 75
and the Canadian Electrical Code part 1, section 16. The power
supply shall not be permanently fixed to building structure or similar
structure.

may be harmful to the eyes; use with caution. For
additional safety, plug the attached dust caps into
the optical transceivers when the fiber cable is
unplugged.
NOTE: Use the proper fiber cable for your transmitter and
receiver pair. Typically, singlemode fiber has a yellow jacket
and multimode cable has an orange or aqua jacket.
