below followed by a description of each panel feature. The indicator panel is described in detail in the next

chapter.

Front Panel

The figure below shows the front panel of the device.

DCM-100

♦ LED Indicator Panel - Refer to the next chapter, “Understanding Indicators,” for detailed information

about each of the DCM-100’s LED indicators.

Rear Panel

The figure below shows the rear panel of the device.

♦ AC Power Connector - For the included power adapter, if you use a power adapter other than the one

included with the product, please make sure it has a DC output of 12V/1A.

♦ Ethernet 10BASE-T Port - The 10BASE-T Ethernet port accepts Category 5 or better UTP cabling with

an RJ-45 connector used to connect the DCM-100 to a LAN device (hub, switch, PC, etc.).

♦ Cable In - This jack is used to connect the DCM-100 to the splitter. This connection uses a standard coax

cable which is the same cable used by your cable TV company.

Connection Architecture

In order for you to enjoy the benefits of your Cable Modem, your PC and TV must be properly connected to the

cable TV wire. The following diagram illustrates a typical PC/TV installation.

♦ Cable TV Wall Outlet - This is the normal cable TV wall outlet installed by your cable company. If you

plan to connect both your TV and your computer to the cable TV wire, the cable TV wall outlet should be

connected to a splitter.

♦ Splitter - This unit, usually provided by your cable TV company during installation, splits the signal onto

a second wire. The two wires coming out of the splitter can be connected to your TV (or set-top box), and

the cable modem.

NOTE: 1. If your cable TV company does not provide a splitter or you chose to buy your own, make sure

you get one with sufficient frequency range (the range should be printed on the splitter). A

range of 5 to 1000 MHz should be adequate. The splitter should provide EMI isolation.

2. Only one splitter should be placed between the point where the cable TV line enters the house

and the Cable Modem/PC (see figure above). If you have multiple TVs, split the line between

the first splitter and the TV, not the line between the splitter and the Cable Modem.

3. WARNING: Do not use amplifiers in the line leading to your Cable Modem. Not only do most

amplifiers only amplify incoming signals, while your Cable Modem receives and sends signals,

but they are also likely to distort cable modem signals.

Understanding Your LED Indicators

Before setting up your Ethernet Cable Modem for the first time, take a few minutes to look over this section and

familiarize yourself with the front panel LED indicators depicted below.

DCM

100

♦ Power - This LED is lit red when the device is receiving power; otherwise, it is unlit.

♦ Link - This LED is lit green to indicate that a valid connection exists between the Ethernet port on the

Cable Modem and your PC. If it is unlit, there is no valid connection.

♦ Act - A blinking green LED indicates that traffic activity is passing through your cable modem port.

♦ Status - This LED is lit green when the Ethernet cable is properly connected to your PC and a traditional

coaxial cable is connected to your Cable Modem tuner. This indicates a successful connection with CMTS.

The LED will now start quickly blinking as the DCM-100 attempts to lock a downstream frequency. If this

is successful, the LED will begin to blink slowly. This indicates the modem is waiting for authentication.

When the blinking stops and the LED remains steady, the Cable Modem is ready to transmit data through

the CATV network.

NOTE:If no lights come, check all of your connection to see if they are properly inserted.

Powering Up For the First Time

You must allow at least 1 to 3 minutes to power up the first time because the DCM-100 must find and secure a

connection.

Setting Up the Device

Before You Start

Local Cable Service

You will need to establish an account with your local cable operator in order to access the Internet with this

modem. They will assist you in setting up the modem to operate on their network.

Then for your modem to communicate with the cable service, you will first need to be able to identify the cable

modem. The Cable Media Access Control (CMAC) address is a unique number that is used for the purpose of

identifying the modem on the network. The CMAC address is found on the rear panel of the modem. You may be

required to provide this information to your cable service operator. For convenient reference you can write the

CMAC address in the space provided below.

CMAC address ______________________________________

System Requirements

The capabilities and limitations of your computer equipment and configuration can affect the overall performance

of your Internet connection.

The DCM-100 Ethernet Cable Modem is designed to work with the following operating systems:

♦ Windows 98/98 SE (Second Edition)

♦ Windows NT 4.0

♦ Windows 2000

♦ Windows ME (Millennium Edition)

♦ Active Ethernet Port or Nic Installed

♦ TCP/IP installed on all devices

All computers interface that are connected to the modem must have either an active Ethernet interface or

network interface card (NIC) installed. You will need to enable TCP/IP protocol on each computer. TCP/IP should

already be installed in any computer with an active Ethernet interface. The instructions for installing TCP/IP

vary depending on the type of system used. These instructions will be included with the NIC or discussed in the

computer’s manual if your PC comes equipped with an Ethernet port. Your cable operator may have additional

instructions for TCP/IP configuration that must be followed.

Installation

The installation of the DCM-100 Ethernet Cable Modem can be completed in a matter of minutes. Be careful to

insure the cables are properly locked into position. Follow these steps (see the figure of the rear panel in Chapter

Two):

1. Connect the coaxial TV cable to the DCM-100 jack labeled “CABLE IN.”

2. Connect the external power adapter into the connector labeled “POWER” and the other end to the

electrical outlet.

3. Connect one end of the 10BASE-T Ethernet cable (Category 5 or better) to one of your PC’s Ethernet ports

and the other end into the DCM-200 connector labeled “ETHERNET.”

Your setup should look something like this:

Important Notice:

♦ The DCM-100 Ethernet Cable Modem will work with the Ethernet port connected directly to a PC, hub,

switch, or a Broadband Router ( i.e. DI-704,DI-713P)

♦ If you shift the Ethernet cable from one PC to another PC, the second PC will not be able to link onto the

Internet until you reboot the DCM-100 by unplugging the power cord and then reinserting it into the

DCM-100.

Troubleshooting

If the Ethernet Cable Modem has been properly set up it is unlikely that you should experience any problems

with it under normal circumstances. However, we list here some possible solutions to problems that you might

experience.

Problem Possible Solution

Cannot access the

Internet or e-mail

service.

Check all connections.

• Make sure the cable TV line and the Ethernet (RJ-45) cable

is securely connected at all points.

• Make sure the AC power adapter is plugged into the device

and the power source. Check the LED indicators to see that

the Power, Link and Status indicators are steadily lit for

an Ethernet-connected device.

Contact your cable service operator to verify that your account is up

to date and that you have two-way service.

There may be a problem with your NIC. Refer to the literature for

the NIC to find a possible solution.

The TCP/IP configuration for the computer may be incorrect.

Double-check to see that these network settings comply with the

instructions given by the cable service operator. Call your cable

company to make sure they have given you the proper settings.

Check your web browser configuration per ISP instruction.

Status LED

indicator blinks

continuously.

Check the cable line connection. If this is secure then there may be a

weak signal coming from the central office. Report the problem to

your cable operator if the cable connection appears to be OK.

LED indicators

appear to be

normal but

Internet access

cannot be

established

Try to establish a new communication with your cable operator’s

central office. This can be accomplished by powering off the

computer and turning it back on.

The TCP/IP configuration for the computer may be incorrect.

The PC Link light

is not green. The

light is off.

The modem is not detecting the Network Interface Card. Make sure

the cables are firmly attached to the network card in the back of

your computer and the modem as well.

Try replacing the Ethernet cable or the network card with known

working components.

Run diagnostic program that came with your network card.

If this is a card that we support, troubleshoot the NIC. Otherwise,

contact the organization that installed or manufacturers the card.

The power light is

not on

Check to make sure the power cable is firmly plugged into the cable

modem. Also, make sure that the power converter is plugged into a

functional socket.

Change outlets with one you know to have power.

Replace Cable Modem.
