The U3CAT6 is an extender system composed of two units – U3CAT6-L and
U3CAT6-R – used to extend USB 3.1 Gen 1 and Gigabit LAN at a distance of up to
100m on a single CAT6a or CAT7 cable. This allows users to extend high speed
USB peripherals far beyond the 3m cable limit specification for USB 3.1.

•The U3CAT6 requires a minimum grade of Category 6a cabling to be used
in order to reach 100m (328 ft) of extension distance. This also includes
the length of patch cable, should it be required. Up to 10m of patch cable
can be used, although the remaining 90m distance must consist of solid
core cabling.
•Unshielded (UTP) cabling may be used if the cable run installation meets
the following requirements:
o The cable is not bundled with other cables
o The cable is run loosely with other Category cables
o The cable is not placed close to sources of interference such as
power lines and radios
o The cable is not looped or coiled
•Foiled (FTP) or Shielded (STP) cabling must be used if the cable run
installation requires the following:
o The cable is bundled with other cables
o The cable is run tights against other Category cables
o The cable is placed near sources of interference like power lines
and radios
o The cable is looped or coiled
Installation
• Connect the U3CAT6-L to the PC using the supplied USB 3.1 cable.
• Optionally, connect the U3CAT6-L to a network switch using a CAT5e or
better patch cord
•Connect the U3CAT6-L and U3CAT6-R together using CAT6a/7 cable, up
to 100m
• Connect USB peripherals to the U3CAT6-R.
• Optionally, connect the U3CAT6-R to a remote network-enabled device
using a CAT5e or better patch cord
• Connect the 24V 1A power supply to the U3CAT6-L Local unit.
• Connect the 24V 2.71A power supply to the U3CAT6-R Remote unit.
