Getting Started
Your Zoom®USB (Universal Serial Bus) 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 dial-
up 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 high-
speed 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.

System Requirements
•A computer running Windows®98, Windows Me (Millennium
Edition), or Windows 2000.
•A USB port on your computer. If you do not have one, you
will need to acquire a USB expansion card and install it in an
available PCI slot.
What You Will Need For Installation
In addition to this manual, check to see that your package includes
the following items. If you are missing any item, contact your
dealer.
•Zoom Cable Modem
•6-foot USB cable
•Power adapter
•CD-ROM or floppy diskette.
Some models may also include a mounting stand.

Getting Started 3
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 “push-
on” F connectors; use only “screw-on” F connectors.

Installing Your Cable Modem
Note: If your cable company provides you with an installation
procedure, follow it instead of the procedure described in
this chapter.
This chapter illustrates a typical cable installation in your home
or office and describes how to connect the Zoom Cable
Modem to your computer.
Installation consists of a few simple steps:
1. Requesting cable modem service from your local cable
company.
2. Connecting the modem and installing the USB driver.
3. Configuring your computer’s network settings.
Contacting your Cable Company
Before you install the Zoom Cable Modem, contact your cable
company to arrange for cable modem service and to establish a
cable modem account. You should have the following information
at hand before you contact your cable company:
1. The Cable Media Access Control (C-MAC) address of the
modem, located on the modem’s bottom case label.
2. The USB Media Access Control (U-MAC) address, also
located on the modem’s bottom case label.
We advise that you record all MAC addresses in the Reference
Information section at the end of this manual.

6 Zoom USB Cable Modem User’s Manual
The diagram below shows a typical cable modem installation. The
cable 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 coming 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, install a high-pass filter at the input of the
2:1 splitter going to the TV sets (see the preceding diagram).
