Network Cabling
The Local Unit and Remote Unit are interconnected by up to 100
meters of Category 5 Unshielded Twisted Pair (UTP) cabling. The
UTP cabling must have a straight-through conductor configuration,
with no crossovers, and must be terminated with 8-conductor RJ45
connectors at both ends.

Power Handling
Some USB devices are powered directly from the USB and do not require
individual power supplies. These devices are called bus-powered devices.
The Ulinx Extender can provide power to these devices so they can be
operated remotely.
Bus-powered devices are further divided into low-power and high-power
categories. Low-power devices are allowed to draw up to 100 mA from the
USB. Typical examples include mice, joysticks, and keyboards without
hubs. High-power devices are allowed to draw up to 500 mA from the
USB. Typical examples include cameras and keyboards with hubs. To
determine if a device is high-power or low-power, consult the user
documentation for the device.
The Ulinx Extender UEC100M/4 can supply power to both low-power and
high-power devices when configured as follows:
•
To operate up to four low-power devices, connect the
power adapter to the Local Unit or the Remote Unit, as
convenient.
•
To operate up to four high-power devices, connect the
power adapter to the Remote Unit.
NOTE: Devices with their own power source are usually considered to be
low-power devices from a USB perspective.
Compatibility
The Ulinx Extender complies with USB 1.1 specifications governing the
design of full speed USB devices. However, B&B Electronics does not
guarantee that all full speed USB devices are compatible with the Ulinx
Extender UEC100M/4.
