Getting Started
Your Zoom® 10BaseT (Ethernet) Cable Modem is designed to
connect your personal computer to the Internet through the
same cable that you use for television reception.
A cable modem provides several advantages over traditional dialup analog modems:
• Transmission speeds are much faster. Because of the increased
speed of a cable modem, you can enjoy faster, more
productive Internet sessions.
• A cable modem frees up your phone line, so you don’t miss
phone calls or have to obtain a dedicated telephone line for
Internet access.
• The cable connection can be “always-on,” so Internet access is
fast and easy.
Cable Modem Service
Your local television cable company provides cable modem service,
also known as cable data service or broadband Internet. The cable
that supplies television service to your home or office is connected
to the modem in the same way that it is connected to your
television set or cable box. You can then get the benefit of highspeed access to the Internet through the local cable company’s
service. The cable connection to the Internet does not interfere
with your regular cable television signals because the modem
service is provided on different channels than television
programming.
Getting Started 1
System Requirements
• Windows® 95/98/Me, Windows NT®, Windows 2000, or
®
OS 7.53 or later.
Mac
• A 10BaseT (Ethernet) port on your computer. If you do not
have one, you will need to install a Network Interface Card
(NIC). Some cable companies will provide the card and install
it for you.
What You Will Need For Installation
In addition to this manual, check to see that your package includes
the following. If you are missing any item, contact your vendor.
•
Zoom Cable Modem
•
6-foot 10BaseT (Ethernet) cable
•
Power adapter
Some models may also include a mounting stand.
2 Zoom 10BaseT Cable Modem User’s Manual
In addition to the items packaged with your modem, you will need
the following items to complete your installation.
• Cable modem service provided by your cable company. The
service must be DOCSIS (Data Over Cable Service Interface
Specification) compatible.
• A power outlet.
• A cable TV outlet.
• The proper length of 75-ohm coaxial cable to reach between
your cable modem and the cable outlet
Note:
Because there is great variety in the way cable is installed,
Zoom does not provide a coaxial cable to connect to your
cable system. If your cable service company does not
provide one, you should purchase a coaxial cable with an
RG-59 or RG-61U rating (75 ohm) and industry-standard
F connectors. For best performance, do not use “pushon” F connectors; use only “screw-on” F connectors.

company.
Requesting Cable Modem Service
Before you install the Zoom Cable Modem, contact your cable
company to arrange for cable modem service and to establish a
cable modem account.
A cable company representative may take care of the entire
installation for you, or you may get an installation CD from the
company and complete the procedure yourself. If you are doing it
yourself, you will need to provide the following information to the
cable company before you make the connections:
The Cable Modem MAC (Media Access Control) Address,

Making the Connections
Typical connections are illustrated below.
The first diagram shows an installation with modem and cable TV.
The modem should be placed on a port of the first splitter inside
your home or office, and should be kept on a separate circuit from
your cable television service.
It is possible that the signal going from the cable modem back to
the cable provider’s central office may interfere with signals from
the TV set-top box for Pay Per View or Video on Demand
services. If this happens, a high-pass filter should be installed at the
input of the 2:1 splitter going to the TV sets, as shown above.

CAUTION
• Locate the modem so that there is one inch of
free space between its top and sides and any
other device or the wall. This free space will
ensure proper air circulation. Do not block
the vents in any way. Failure to allow proper
air circulation can result in serious damage to
the cable modem.
• Do not place any items on top of the modem
while it is powered up.
• Do not place the modem near a heating or air
conditioning duct, in direct sunlight, or in a
location susceptible to drastic temperature
changes.

After you have completed your Internet session, just close your
browser. The Zoom Cable Modem remains connected with the
cable system and stays ready to open another session.
Unplugging the Modem
If the Zoom Cable Modem is unplugged or if power is lost for any
other reason, all communication between the modem and the cable
system is terminated. When the power is restored, the cable
modem must go through the full synchronization process before
you can connect to the Internet. This process is performed
automatically when the modem is powered up.

• Check all physical connections. The READY, 10BT,
and SYNC lights on the modem’s front panel must all
be a steady green before your cable modem will work.
• Check to see that your cable TV service is working. If
not, call your cable service provider.
• Verify that the MAC and Ethernet Adapter addresses
you gave to your service provider are correct, and that
they are entered into their system. See page 5.
• Make sure your Network Interface Card is functioning
correctly. Refer to the documentation if necessary.
• Check that TCP/IP is configured correctly. Refer to
the section of this manual entitled Configuring Your
Computer’s Network Settings on page 8. Verify
that the TCP/IP parameters supplied by your cable
company are correct and up-to-date.

Solution: Check that you are using the adapter that came with
your cable modem.
Problem: I receive the message “Unknown Network
Adapter.”
Solution: This problem can occur if a Network Interface Card is
physically present and was recognized by Plug-andPlay, but was not installed correctly. Reinstall it.
Problem: I receive the message “Undetected Network
Adapter.”
Solution: The Network Interface Card is missing or incorrectly
installed. Reinstall it.
Problem: I receive the message “Missing Internet
Protocol.”
Solution: Refer to Configuring Your Computer’s Network
Settings on page 8.
Problem: I receive the message “Cannot Find Files; Insert
Operating System Disk.”
Solution: Your computer is looking for the files included on the
original operating system CD or diskettes that came
with your computer. Remove your modem CD or
diskette (if any) and insert your operating system CD
or disk. Be sure to remove the operating system CD
when you’re done and reinsert your modem CD or
diskette if applicable.
Appendix B: Troubleshooting 33
Problem: The Cable Modem’s SYNC light blinks for 5
minutes, goes off, comes on again and repeats.
Solution:
• Make sure the connection is secure.
• Check with your cable service provider to make sure
that high speed access is available and running.
• In rare instances, the cable signal may be low. Be sure
the modem is attached to one of the ports on the first
splitter after the cable enters your home or office (see
page 21).
• Make sure there is no video amplifier on the same line
with the cable modem. (A video amplifier prevents
data from returning to the cable provider’s central
office.)
Tip:
When your cable modem service is restored after a
disruption, if you are having difficulty communicating,
disconnect and then reconnect the power, and let the
modem go through the synchronization process again.
