USB over Twisted Pair Extender
1
The Crestron®USB over Twisted Pair Extender (USB-EXT) delivers
reliable USB signal extension for use in a boardroom, classroom,
auditorium, command center, or residence. Without any special setup
or configuration, the USB-EXT enables wire runs up to 100 meters
(~330 feet) over a single, low-cost twisted-pair cable.
The USB-EXT is compatible with USB 1.1 and High-Speed USB 2.0,
supporting virtually any USB device such as keyboards and mice,
game controllers, cameras, mobile devices, printers, hubs, and
memory devices. It is compatible with Windows®and Mac®
computers without requiring any additional drivers.
The USB-EXT is composed of two extender components. The “local”
extender connects to your computer or other USB host, while the
“remote” extender provides connections for your USB devices at
some remote location. Linking the two extender components requires
just one run of inexpensive CAT5 (or better) twisted-pair cable.
The USB-EXT contains a local extender, remote extender, power
supply and a USB cable.
Introduction
NOTE: Crestron does not guarantee that all USB devices are
compatible with the USB-EXT.
On the local and remote units, check that the Power, Host and Link LEDs are on and that the Activity LED for the connected
USB port is blinking. If any LED is permanently off, then the cabling between the local and remote units is not properly installed
or is defective.
Verify device is properly installed on computer:
For Windows Users:
Open Device Manager to confirm that that USB-EXT has been installed correctly. Expand the entry for Universal Serial Bus
controllers by clicking the + sign. If the USB-EXT has been installed correctly, you should find it listed as a “Generic USB
Hub”.
For Mac OS X Users:
Open the System Profiler to confirm that the USB-EXT has been installed correctly. In the left hand column under Hardware,
select “USB” and inspect the right hand panel. If the USB-EXT has been installed correctly you should find it listed as a
“Hub” under the USB High-Speed Bus/USB Bus.
If the unit is not detected correctly or fails to detect, please consult the Troubleshooting section on the following page.

device does not operate properly, consult the user documentation for the device for further troubleshooting.
•If the device operates properly when directly connected to the computer, connect another device (of a
different type) to the USB-EXT. If the second device does operate properly, the first device may not be
compatible with the USB-EXT.
If the steps above do not solve the issue, update your system BIOS, chipset or USB host controller drivers from
your System/Mother board manufacturer’s Web site.
USB device is attached to either of the
remote USB ports but the associated
