FCC Radio Frequency Interference Statement Warning
The USB Link II has been tested and found compliant with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when installed and operated in a commercial environment. The USB
Link II generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with this user guide, may cause harmful interference to radio communications.
Operation of the USB Link II in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.
CE Statement
We, Magenta Research, declare under our sole responsibility that the USB Link II, to which this
declaration relates, is in conformity with European Standard EN 55022/A1 Class A, and
EN 50082-1 (IEC 801-2, IEC 801-3, IEC 801-4)
SAFETY WARNING
Installation • This equipment is to be installed in a restricted access location.
Connection • Not for direct connection to Telecommunication Network Circuitry (TNV)
Power sources • This equipment should be operated only from the power source indicated on
the product. This equipment is intended to be used with a main power system with a grounded
(neutral) conductor. The third (grounding) pin is a safety feature, do not attempt to bypass or
disable it. This equipment can be powered from redundant power sources. Disconnect all power
sources before servicing.
Power disconnection • To remove power from the equipment safely, remove all power cords
from the rear of the equipment, or from the power source receptacle (wall plug).
Power cord protection • Power cords should be routed so that they are not likely to be stepped
on or pinched by items placed upon or against them.
Servicing • Refer all servicing to qualified service personnel. There are no user-serviceable parts
inside. To prevent the risk of shock, do not attempt to service this equipment yourself because
opening or removing covers may expose you to dangerous voltage or other hazards.
Slots and openings • If the equipment has slots or holes in the enclosure, these are provided to
prevent overheating of sensitive components inside. These openings must never be blocked by
other objects.

Network Cabling
The transmitter and receiver units are interconnected by up to 150 meters of
Category 5/6 Unshielded Twisted Pair (UTP) cabling. The UTP cabling must
have a straight-through conductor configuration, with no crossovers, and must
be terminated with T568B specified RJ45 connectors at both ends.
NOTE:Category 5/6 UTP cabling is the standard data
communications cable installed in most commercial and
some residential buildings.
USB Cables
USB cables have two distinct connectors. The Type A connector is used to
connect the cable from a USB device to the Type A port on a computer or
hub. The Type B connector is used to attach the USB cable to a USB device.

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 USB Link II can provide power to these devices so they can be operated
remotely.
Bus-powered devices are further divided into low-power and high-power cate-
gories. 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 550 mA from the USB. Typical ex-
amples include cameras and keyboards with hubs. To determine if a device is
high-power or low-power, consult the user documentation for the device.
NOTE: Devices with their own power source are usually considered to be
low-power devices from a USB perspective.
Compatibility
The USB Link II complies with USB 2.0 and 1.1 specifications governing the
design of full speed USB devices. However Magenta Research does not
guarantee that all full speed USB devices are compatible with the USB Link II.

Before You Begin
Before You Begin
Before you can install the USB Link II, you need to prepare your site:
1. Determine where the host computer is to be located and set up the
computer.
2. Determine where you want to locate the USB device(s).
3. Ensure you have enough Category 5/6 UTP cabling to connect the
two locations. (Maximum 492 ft or 150 m)
Installing the TRANSMITTER Unit
1. Place the TRANSMITTER unit near the host computer.
2. Plug the Type B connector on the USB cable (included) into the
Host port on the TRANSMITTER.
3. Plug the Type A connector on the USB cable into the USB port on
the computer.
NOTE:There is no separate power supply required for the
Transmitter unit.
Installing the RECEIVER Unit
1. Place the RECEIVER unit near the USB device(s).
2. Plug the power adapter into a suitable AC outlet.
3. Connect the power adapter to the RECEIVER unit.

Connecting the Transmitter and Receiver
Connecting the TRANSMITTER Unit to the RECEIVER Unit
NOTE:To ensure proper operation, we recommend that only
Category 5 or better, Unshielded Twisted Pair (UTP) cabling be used to
connect the TRANSMITTER unit to the RECEIVER unit. The UTP cabling
must have a straight-through conductor configuration with no crossovers, and
must be terminated with T568B specified RJ45 connectors at both ends.
1. Plug one end of the Category 5/6 UTP cabling (not included) into
the Link port on the TRANSMITTER unit.
2. Plug the other end of the Category 5/6 UTP cabling into the Link
port on the RECEIVER unit.
MAGENTA USB LINK II

Checking the Installation
1. Check that the Power LEDs on the TRANSMITTER and
RECEIVER units are both on.
2. Check that the Link LEDs on the TRANSMITTER and RECEIVER
units are both on.
3. On the host PC, open the Device Manager applet. Expand the
entry for Universal Serial Bus controllers by clicking the “+” sign. If the USB
Link II has been installed correctly you should find it listed as a Generic USB
Hub.
Connecting a USB Device
1. Install any software required to operate the USB device(s). Refer
to the documentation for the device(s), as required.
2. Connect the USB device(s) to the device port on the RECEIVER
unit.

MITTER and RECEIVER
are off.
Cause:
There is no connection
between the TRANSMIT-
TER and RECEIVER
units.
1. Ensure that a Category 5 UTP cable with straight-
through conductors is connected between the
TRANSMITTER and RECEIVER units.
2. Connect a short Category 5 patch cord between the
TRANSMITTER and RECEIVER units. Recheck
the operation of the system.
