introduction
Accessing the Diagnostics Display through the CD-ROM
A button on the CD-ROM menu called “Look at Diagnostics”(found under the
“About My Cable Modem”menu), launches your browser and displays status and
diagnostic information stored within the modem in HTML format.
Please note that before this page can be displayed, your PC must receive an IP
address assignment from the Cable company’s server, over the cable network.
After the diagnostics page is displayed, you may want to “bookmark”this IP
address in your browser.
What’s on the CD-ROM
Insert the Cable Modem CD-ROM into your CD-ROM drive to view troubleshooting tips,
the internal diagnostics, and other valuable information.
NOTE: You will need to use the CD-ROM to install the USB driver if you are connecting
via the USB port.
CD-ROM Contents:

introduction
Computer Requirements
•Personal computer with the following minimum system requirements (note that the
minimum requirements may vary by cable company):
An Ethernet card makes it possible for your computer to pass data to
and from the internet. You must have an Ethernet card and software
drivers installed in your computer. You will also need a standard
Ethernet cable to connect the Ethernet card to your cable modem.
USB Port USB (Windows 98SE/2000 only) N/A†
The Universal Serial Bus is a high speed bus that enables your
computer to communicate simultaneously with a variety of
peripherals. However, if you have other peripherals that send and
receive a lot of information, such as speakers, printers or scanners,
we recommend using an Ethernet card to support this modem.
†Mac Users: Mac OS or any other OS other than Windows 98SE or 2000 are not currently
supported for USB installation. Please use the Ethernet connection.
Placing the Rubber Feet on
the Cable Modem
A set of rubber pads have been packaged with your
modem. These pads (or "feet") can be attached to keep
the modem from sliding around on your desktop.
You have 2 options for placing the pads:
Option 1: Attach the pads to the four slight
indentations on the back of the modem.
Option 2: Attach the pads to the “rudders”on the
bottom of the cable modem. Be sure to
equally space the pads for best results. Option 2:
Equally space the feet on
the bottom of the unit

What The Modem Does
The RCA Digital Cable Modem serves as a two-way high-speed bridge between your
personal computer and a cable Internet Service Provider (ISP). It converts information
that originates from the Internet or your computer into electronic messages that can be
transported over the same wires your cable company uses to transport video signals.
What The Modem Needs To Do Its Job
The Right Cable Company
Make sure your local cable company provides data services that use cable TV industry-
standard DOCSIS (EuroDOCSIS for model DCM28x and DCM29x) technology.
The Internet Service Provider (ISP)
Your cable company provides you access to an Internet Service Provider (ISP). The ISP is
your gateway to the Internet. It provides you with a pipeline to access Internet content
on the World Wide Web (WWW).
Check with your cable company to make sure you have everything you need to begin;
they’ll know if you need to install special software or re-configure your computer to
make your cable internet service work for you.

before you begin
Contact Your Local Cable Company
You will need to contact your cable company to establish an internet account before you
can use your modem. You should have the following information (which you will find on
the sticker on the modem) ready:
•The serial number
•The model number of the modem
•The Media Access Control (MAC) address
CAUTION
Your cable company should always be consulted before
installing a new cable outlet. Do not attempt any rewiring
without contacting your cable company first.
Please verify the following with the cable
company:
•The cable service to your home supports DOCSIS-compliant (EuroDOCSIS-compliant
for model DCM28x and DCM29x) two-way modem access.
•Your internet account has been set up.
•You have a cable outlet near your PC and it is ready for cable modem service.
Record your information here:
Serial Number: _________________________
Model Number: _________________________
MAC Address: __________________________

NOTE: It is important to supply power to the modem at all times. Keeping
your modem plugged in will keep it connected to the Internet. This means
that it will always be ready when you are. To disconnect just your computer
from the Internet, use the ON/OFF button to put the modem in standby
mode.
