Introduction

The EZ Connect Cable Modem provides high-speed Internet access over the the same
cable network system that brings cable TV service to the home. The data
transmission rate on the cable connection is asymmetric, in that it provides a higher
data rate in the downstream (receive) direction than in the upstream (transmit)
direction. Asymmetric operation is ideal for typical home and small office use where
files and information are downloaded more frequently than uploaded. This modem
has a USB connection which provides plug and play installation, and an Ethernet
connection that allows you to connect up to 16 computers with the use of an
Ethernet hub.

Key Features

• High-speed Internet access over a cable network system

• Data rate of up to 10 Mbps upstream and 40 Mbps downstream

• Always-on digital connection eliminates dial-up delays, and provides transparent
reconnection when initiating any network request

• Operation with cable suppliers is ensured by DOCSIS compliance

• Enhances security with DES data encryption

• Supports Windows 98, Windows 98 Second Edition, Windows 95, Windows NT

4.0, Windows Me and Windows 2000

• Supports up to 16 users through Ethernet connection

• Delivers USB plug-and-play installation and configuration

• For USB connection:

- A PC equipped with a USB port

- Windows 98, Windows 98 SE, Windows Me or Windows 2000

• For Ethernet Connection:

- A PC with a 10/100 Mbps Ethernet adapter card installed

- Windows 95 or later, Windows NT 4.0 or later

Installing the Modem

Connecting the Modem

Before connecting the EZ Connect Cable Modem, contact your cable service provider
and check the following points:

• Be sure that your service provider supplies a two-way data link.

• Check that they have set up an Internet Access Account. To do this you will need
to provide information that may include the product number and the modem MAC
address. You will find this information on the label on the base of the modem.

The modem must be correctly connected to the service provider’s cable jack. If you
are connecting both a TV and the modem to this outlet, you will need to use a
splitter. The splitter duplicates the signal onto a second wire.

1. Connect a 75-ohm coaxial TV cable between the splitter and the cable

connector at the back of the modem. Ensure that you do not bend the center
wire of the connector. Tighten both connectors by hand.

2. Connect the modem to a surge-protected power source.

3. Connect the modem:

- to a computer using the USB connection. (See “USB Installation for
Windows 98, Window 2000 and Windows Me” on page 6.)

or

- to a computer or Ethernet hub/switch using the Ethernet connection. ( See
“Making a Connection to the Ethernet Port” on page 7.)

Ethernet port on the modem to a PC.

1. Make sure you have installed a
10/100Mbps network adapter card in
the PC.

2. Prepare straight-through shielded
or unshielded twisted-pair cables
with RJ-45 plugs at both ends. Use

3. Connect one end of the cable to the
RJ-45 port of the network interface card, and the other end to the Ethernet port
on the modem. When inserting an RJ-45 plug, be sure the tab on the plug clicks
into position to ensure that it is properly seated.

Caution: Do not plug a phone jack connector into any RJ-45 port. Use only twisted-pair

cables with RJ-45 connectors that conform with FCC standards.

Notes: 1.

When connecting to a hub or switch use crossover cabling. (Refer to “Port
and Cable Assignments” on page 10 for a description of crossover cable.)

2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

Port and Cable Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only

twisted-pair cables with RJ-45 connectors that conform with FCC
standards.

An Ethernet twisted-pair link segment requires two pairs of wires. Each wire pair is
identified by two different colors. Each wire pair must be attached to the RJ-45
connector in a specific orientation detailed below.

The Ethernet port on the modem is an MDI-X port, which allows straight-through
cable connections to PCs, and to hubs and switches with MDI ports. In
straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected
straight through to pins 1,2, 3 and 6 at the other end of the cable. For connection to
hubs or switches which have MDI-X ports, a cross-over cable must be used.

Port and Cable Assignments

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal

crossover (MDI-X), the two pairs of wires must be straight-through.

If the twisted-pair cable is to join two ports and either both ports are labeled with an
“X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be
implemented in the wiring.
