INTRODUCTION
TheEZConnect USB/ETH cable modem is based on the Broadcom 3350 chipset and is
DOCSIS 1.0 certified. This cable modem provides high speed access to the Internet
through a coaxial cable with a cable service provider. It also utilizes the cable television
network to transmit high-speed data to your PC.
This user’s guide describes how to set up and use theEZConnect USB/ETH cable
modem. Before installing the cable modem, you should read this installation guide
thoroughly to ensure proper operation.
ACRONYMS
CM Cable Modem. A device that converts the data collected from the Internet
and sent to a home through a cable TV company's line into data that a PC
can understand. The modem lets you to connect to the Internet without a
telephone line. Cable modems can ferry data up to 38 mbps downstream
and from 200 kbps to 10 mbps upstream. The transmission rate will depend
on your service provider.
CMTS Cable Modem Termination System. A data-switching system that routes
data between cable modem users and the Internet.
DOCSIS Data Over Cable Service Interface Specifications. A cable TV industry
standard set by CableLabs for cable modems. This standard ensures that
certified modems can be used by all U.S. cable systems that market
broadband connections.
RF Radio Frequency.
TCP/IP Transmission Control Protocol/Internet Protocol. The primary protocol
used on the Internet, TCP/IP supports data communication across
interconnected networks and applications. All PCs connected to the
Internet use TCP/IP to communicate with each other.
USB Universal Serial Bus. A port that connects up to 127 peripheral devices —
including modems, printers, scanners, keyboards and PC mice —to a
single PC in a networking arrangement.

INSTALLATION PROCEDURE
The installation procedure is separated into fivesteps. Please take note of them before
proceeding with the installation. The installation checklist below will help you verify
each process.
Installation Check List
Item Task Checked off
1Ensure the selected location is free of dust and meets all the
following requirements:
lNear the cable drop connection and power source.
lInstall cable modem on a stable and flat surface.
Cables can reach all devices that need to be connected.
Ensure the bottom, sides, and rear of the cable modem
are clear of obstructions.
2Check your PC environment:
lVerify PC to be connected to the cable modem has an
Ethernet Network Interface Card (NIC) with TCP/IP
networking enabled or a USB port is available.
lThe cable modem does not support the USB and
Ethernet Port at the same time. Please choose one
connection type.
lThe cable modem supports Ethernet NIC in all
Microsoft Windows operation systems.
lThe cable modem supports USB in Microsoft
Windows 98, Windows 2000, or Windows Me.
3Connect the cable modem’s F-connector to the cable TV
coaxial drop cable. (If you also subscribe to cable TV
services, install a cable splitter/directional coupler when
applicable.)
4Attach the end of the power adapter cord into the cable
modem’s power connector and connect the other end to the
power plug. Plug the cable modem’s power adapter into the
wall outlet. Check if the cable modem’s power LED is on
and initialized.
5Power on all other devices: PCs, Ethernet hub and all other
equipment when applicable.

Physical Placement
Place the cable modem on a stable, flat surface such as a desktop, close to the CATV
cable drop connection and all devices to be connected. The surrounding areas of the
cable modem must remain unobstructed to ensure adequate airflow and to prevent the
unit from overheating.
Caution: Do not place the cable modem on an uneven or soft surface.
Connecting to the Cable System
ØVerify that the cable modem is not connected to the power source. It will generate
installation difficulty if you power on the cable modem before connect RF coaxial
cable.
ØLocate the RF coaxial cable from the CATV wall outlet.
ØInstall a cable splitter/directional coupler if it is needed to separate signals for TV
and PC usage.
ØConnect the RF coaxial cable to the cable modem’s F-connector. Hand-tighten the
connector, making sure it is finger-tight.
Caution: Do not over-tighten the connector because doing so can break off the
connector.
ØMake sure all other coaxial cable connectors and all intermediate splitters,
couplers, or ground blocks are securely tightened from the distribution tap to the
cable modem.
Note: Loose connectors inside the building or residence can cause intermittent
cable modem operation.
Caution:To ensure compliance with FCC limits, connection to the cable system
must be made with a high-quality, shielded cable. If the quality or general
condition of the coaxial cable is in question, it is recommended that you replace
the coaxial cable.
