2.2 Safety Precautions
For your protection, observe the following safety precautions when setting up and using your equipment. Failure to observe these precautions
may results in serious personal injury and damage to your equipment.
• Make sure the voltages and frequency of the power outlet matches the electrical rating labels on the AC Adapter.
• Do not place any object on top of the device or force it into a confined space.
• Never push objects of any kind through openings in the casing. Dangerous voltages may be present. Conductive foreign objects could produce
a short circuit that could cause fire, electrical shock, or damage to the equipment.
• When installing the Smart One CMX300, be sure to observe the anti-static caution in the installation section of this user’s guide. This will
prevent damage to the board and other components.

DOCSIS1.0CableModemUserGuideRev.3.0 3
• Whenever there is danger of lightning, disconnect the power cable and the coaxial cable from the cable modem to prevent damage to the unit.
The use of an AC protection device will not completely protect the cable modem product from damage caused from the transmission across
the cable TV network.

Chapter 3 Hardware Installation
This chapter describes the proper steps for connecting your new Cable Modem. Please be sure to follow the steps in the sequence outlined below.
Failure to do so could result in improper operation or failure of your Cable Modem.
Step 1:
Connect a DOCSIS 1.0 cable feed to the F-connector on the back of the cable modem as illustrated in Figure 1. Ensure that the center conductor
of the 75 ohm coaxial cable is inserted directly into the center of the F-connector. Secure the coaxial cable by carefully threading the outer shell
of the coaxial cable connector onto the F-connector in a clockwise direction until tight. Be careful not to over-tighten the connector or you may
damage either the connector or the cable modem.
NOTE:
To speed up the initial cable modem registration process, the coaxial cable should be connected to the modem prior to the power connector.
Figure 1. Connecting the Coaxial Cable
Cable Feed (F Connector)

DOCSIS1.0CableModemUserGuideRev.3.0 5
Step 2:
Connect the AC Adapter to the Cable Modem by inserting the barrel-shaped connector into the mating power connector on the back of the Cable
Modem as illustrated in Figure 2. Exercise carefully to ensure the connectors are properly aligned prior to insertion and ensure the two
connectors engage completely. The cable modem is shipped with an AC adapter. Remember to use only power adapter that came with the
cable modem. Other power adapters might have voltages that are not correct for your particular cable modem. Using a power adapter with
the wrong voltage can damage the cable modem. The cable modem power input requires 12 VDC input with minimum 1000 mA current. The
+12 V is on the center connector, and ground is on the outer connector.

Step 3:
Connect the Cable Modem to an IEEE 802.3 10BaseT / 802.3u 100Base-TX Network using a RJ-45 male-terminated CAT-5 cable as illustrated
in Figure 3a.
Figure 3a. Connecting to a Network Interface Card
Connect the USB cable to the Cable Modem by inserting the rectangular end of an USB cable into the USB port of the Cable Modem as
illustrated in Figure 3b. Ensure the connectors lock together by listening for a snap.
CAUTION 1:
Deciding Which Installation Process to Use on Your Computer:
You are strongly recommended to connect to the Internet using either the Ethernet port or the USB port only. You should not have the USB
cable and the Ethernet cable plugged into the cable modem to the computer at the same time. In most cases CATV ISPs provide one IP address
only, having the USB and Ethernet cables plugged into the cable modem at the same time might cause you to access the Internet improperly.
CAUTION 2:
Connecting to More Than one Computer Devices:
10/100Mbps
Ethernet

DOCSIS1.0CableModemUserGuideRev.3.0 7
This cable modem provides you the feature for Ethernet and USB interfaces to operate on 2 different computer devices simultaneously. However,
you have to obtain additional IP addresses from your cable service provider.

Chapter 4 Ethernet Installation
Setting Up the Computer to Use an Ethernet Connection
If your computer is already equipped with a functional Ethernet Network Adapter (NIC card), you can use the Ethernet port to connect to the
cable modem through a RJ45 cable.
Before you connect your cable modem to your PC LAN port, please set the IP address to "Obtain an IP address automatically" as below, and
ensure the TCP/IP protocol is installed on your system and configured correctly in your PC.

DOCSIS1.0CableModemUserGuideRev.3.0 9
Following is an example of configuring the TCP/IP Protocol on Windows 98 Operating Systems,
1. Click on the "Start" button; choose "Settings, and then "Control Panel", Double click on the "Network" icon click "'Properties".
2. A list of installed network components appears. Look for an entry named TCP/IP. This entry may be followed by an arrow and a
description of the NIC hardware device installed in the computer. If you don't see "TCP/IP" listed anywhere in "The following network
components are installed" dialog box, click on "Add" button, choose "Protocol", and click "Add" button again. Select "Microsoft" as the
manufacturer and then scroll down in the list on the right to find "TCP/IP".
If you see "TCP/IP" listed, proceed to step 4
3. Click the OK button. You will be prompted to insert the Windows 98 installation/upgrade CD.
4. Scroll down in the box until you find a line that says "TCP/IP" followed by the name of your Ethernet adapter. Click on "Properties" and
choose "Obtain an address automatically" which means that your PC has been configured to use DHCP (Dynamic Host Configuration
Protocol).
5. Click OK.
Congratulations! You have successfully set up your new cable modem.
CAUTION:
Using the Ethernet port allows you to use a hub, switch or a router to share your cable modem between multiple computers in your network. To
do this, you may need to obtain additional IP addresses from your cable service provider.

Chapter 5 USB Installation
Using the USB port to install the CMX300 is simpler and quicker
than selecting the Ethernet port, since you do not need to install a
network interface card (NIC).
5.1 Using USB with the Windows 98 or Windows Me Operating
System
To use the USB port with Windows 98/Me:
1. Connect USB cable from PC to CMX300
2. Connect RF cable and power on cable modem. Wait until cable
modem registers and LINK LED lights steadily, it will take from
40 sec to 4 min depending on network traffic.
3. Cable modem may reboot if you have previously connected it
through the Ethernet port
4. Windows will prompt for new hardware found
5. Insert the Driver CD-ROM
Click “Automatic search for….” then “Next”
