Introduction
The EZ Connect CableModemprovides high-speed Internetaccess 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 16computers withthe use ofan
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 16users through Ethernet connection
• Delivers USB plug-and-play installation and configuration

Connecting the Modem
Before connecting the EZ Connect Cable Modem,contactyour 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.)

Making a Connection to the Ethernet Port
You can use straight-through
twisted-pair cable to connect the
Ethernet port on the modem to a PC.
1. Make sure you have installed a
10/100Mbps networkadaptercardin
the PC.
2. Prepare straight-through shielded
or unshielded twisted-pair cables
with RJ-45 plugs at both ends. Use
100-ohm Category 3, 4 or 5 cable
for this 10 Mbps Ethernet
connection.
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).

Troubleshooting
Cannot Connect to the Internet
• Confirm that you have established an account with your service provider and that
a two-way cable service is provided.
• Check that all cables are connected to the modem and PC. Verify
that the proper
cable type is used and its length does not exceed specified
limits. Check the cable
connections
for possible defects. Replace the defective cable if necessary.
• Verify that the modem and computer are powered on.
• If the power source has a switch, ensure that it is switched on.
• Check the power outlet by plugging in another device that is functioning properly.
• Check the power cord with another device.
• Power off the modem, wait for 20 seconds and then power back on.
• Close down your computer, power off, wait for 20 seconds, power back on, and
then re-boot.
• For USB connection:
- Check that the USB driver is correctly installed see “USB Installation for
Windows 98, Window 2000 and Windows Me” on page 6.
• For Ethernet connection:
If the Link LED on the network adapter’s bracket does not light, check the
following items..
- Check that your computer is properly configured for TCP/IP see “Ethernet
Installation for Windows” on page 6.
- Make sure the UTP cable type complies with IEEE 802.3 Ethernet, or IEEE
802.3u standards for the type of network you are using. Also, make sure
cable lengths are within the requirements specified. (See “Making a
Connection to the Ethernet Port” on page 7.)
- Inspect all network cables and connections. Make sure the network cable
is securely attached to the network adapter’s connector.
- Make sure the correct network card driver is installed for your operating
system. If necessary, try reinstalling the driver.
- Make sure the computer and other network devices are receiving power. If
you suspect a power outlet to be faulty, plug another device into it to verify
that it is working.
- If the the network adapter’s speed or duplex mode has been configured
manually, check that it matches that of the attached network device port.
Note that it is recommended to set the adapter to auto-negotiation when
installing the network driver.

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.
Pin MDI-X Signal Name MDI Signal Name
1 Receive Data plus (RD+) Transmit Data plus (TD+)
2 Receive Data minus (RD-) Transmit Data minus (TD-)
3Transmit Data plus (TD+) Receive Data plus (RD+)
6Transmit Data minus (TD-) Receive Data minus (RD-)
4,5,7,8 Not used at 10 Mbps Not used at 10 Mbps

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.
Crossover Wiring
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.
