2.2 About the USB-CAT5 Extender  
The USB-CAT5 Extender breaks the five-meter distance barrier for the  
connection of USB devices and allows users to enjoy the benefits of USB  
technology beyond the desktop. With the USB-CAT5 Extender, USB  
devices can be located up to 50 meters from the host computer. In addition,  
the USB-CAT5 Extender can supply power to remote low-power and some  
high-power USB devices.  
The product is composed of two individual units, the Local Unit and the  
Remote Unit.  
2.2.1 The Local Unit  
The Local Unit connects to the host computer using a conventional  
USB cable.

CHAPTER 2: Introduction  
2.2.2 The Remote Unit  
The Remote Unit connects to the USB device using a conventional  
USB cable. The Remote Unit of the USB-CAT5 Extender IC244A  
enables you to connect one full-speed or low-speed USB device. The  
Remote Unit of the USB-CAT5 Extender IC246A enables you to  
connect two full-speed or low-speed USB devices.

2.2.3 Network Cabling  
The Local Unit and Remote Unit are interconnected by up to 50  
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.

2.2.4 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.

2.2.5 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-CAT5 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 USB-CAT5 Extender can supply sufficient power to support all low-  
power devices and most high-power devices. Devices that place a very heavy  
power drain on USB (>300 mA) are not supported. Most USB devices  
operate well within this power budget.  
NOTE  
Devices with their own power source are usually considered to be low-power devices from a USB  
perspective and are thereby compatible with the USB-CAT5 Extender.  
2.2.6 Compatibility  
The USB-CAT5 Extender complies with USB 1.1 specifications governing  
the design of full-speed and low-speed USB devices. However, Black Box  
does not guarantee that all USB 1.1 devices are compatible with the USB-  
CAT5 Extender.

CHAPTER 3: Installation  
3.Installation  
3.1 Before You Begin  
Before you can install the USB-CAT5 Extender, 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.  
3. If you are using surface cabling, ensure you have enough Category 5  
UTP cabling to connect the two locations.  
OR  
If you are using premise cabling, ensure Category 5 UTP cabling is  
installed between the two locations, with Category 5 information  
outlets located near both the computer and the USB device.  
3.2 Installing the Local Unit  
1. Place the Local Unit near the host computer.  
2. Plug the Type B connector on the USB cable (included) into the Host  
port on the Local Unit.  
3. Plug the Type A connector on the USB cable into the USB port on  
the computer.  
3.3 Installing the Remote Unit  
1. Place the Remote Unit near the USB device.  
3.4 Connecting the Local Unit to the Remote Unit  
NOTE  
To ensure proper operation, we recommend that only Category 5, or better, Unshielded Twisted Pair  
(UTP) cabling be used to connect the Local Unit to the Remote Unit. 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.  
3.4.1 With Surface Cabling  
1. Plug one end of the Category 5 UTP cabling (not included) into the  
Link port on the Local Unit.
