Getting Started
Your Zoom™ cable modem is designed to connect your
personal computer to the Internet through the same cable that
you use for television reception. You can connect your external
cable modem to a computer in one of two ways: You can use
its Ethernet (10/100BaseT) interface or its USB (Universal
Serial Bus) interface.
Contacting Your Cable Company
Please fill out the information in the following table before you
begin installing your Zoom cable modem. Your cable service pro-
vider needs this information to ensure that your modem connects
to the Internet successfully. Note: This manual assumes that you
have already arranged for cable modem service and established a
cable modem account with your cable company.
Important Installation Information
The following information is located on the label on the back of your
modem. You will be asked to provide it when you call for installation.

You Will Also Need
To complete your installation, you must have these items:
•Cable modem service provided by your cable company. The
service must be DOCSIS- (Data Over Cable Service Interface
Specification) or EuroDOCSIS-compatible, where applicable.
•A power outlet.
•A 75-ohm coaxial cable that will connect to the cable TV sys-
tem and that can reach to where you intend to place your cable
modem.
Note: Because there is great variety in the way cable is installed,
Zoom does not provide a coaxial cable to connect your
modem to your cable system. Your cable company may
provide the appropriate length cable for your use. If the
company doesn’t supply the cable, you should buy a coax-
ial cable with an RG-59 or RG-61U rating (75 ohm) and
industry-standard F connectors.
Tip: For best performance, do not use “push-on” F con-
nectors; use only “screw-on” F connectors.
To Use the Ethernet Option
If you want to use your cable modem’s Ethernet interface option,
make sure you have
•A computer running the Windows®95, 98, NT 4.0, 2000, Mil-
lennium (Me), XP, or Linux operating system, or a Macintosh®
running System 7.5 or later.
•An Ethernet (10BaseT or 100BaseT) port in the computer you
want connected to your cable modem. If your computer
doesn’t have an Ethernet port, you will need to buy a Network
Interface Card (NIC) and install it before completing the cable
modem setup. Some cable operators offer the option of pro-
viding and installing the NIC card.
6 Zoom Cable Modem User’s Manual
To Use the USB Option
If you want to use your cable modem’s USB interface option, make
sure you have
•A computer running the Windows 98, 2000, Millennium (Me),
or XP operating system.
•An available USB port on your computer. If your computer
doesn’t have a USB port, we recommend that you use the ca-
ble modem’s Ethernet option.
IMPORTANT
You can use either the Ethernet or the USB option but not both
simultaneously. If you change interface options while the cable
modem is connected, the modem will resynchronize with the cable
company. You must restart your computer. You may also have to
install software from your CD.
Familiarizing Yourself with Your Cable
Modem
Your Zoom cable modem has several LED light indicators on its
front panel, so you can monitor its operation and perform trouble-
shooting if necessary.
The following table defines these lights and explains how to inter-
pret them. This table is for reference only and is not required for
cable modem installation.
