Introduction 1
Introduction
Your DOXport 1110 Cable Modem
Your DOXport 1110 cable modem gives you high-speed, always on access to the Internet
through your cable TV (CATV) network. The DOXport 1110 works on any cable system that
complies with the Data Over Cable Services Interface Specifications (DOCSIS).
Package Contents
Check the contents of the package. It should contain the items shown in Figure 1.
Please contact the place of purchase if any of the above listed items are missing or damaged. If
your cable modem was obtained directly from your cable operator, it may have been bulk
packaged without the cables, setup sheet, and user’s guide.
Before You Start
Before you install your DOXport 1110, you need the following items. These items are not
supplied with the DOXport 1110.
1. DOCSIS cable modem service from your local service provider
2. CATV (cable TV) outlet
3. Two-way CATV splitter
4. Two RG6 coaxial cables; one cable connects the CATV outlet to the 2-way
splitter and the other cable connects one output of the splitter to your cable
modem
5. Computer with 10 Base-T Ethernet LAN port OR computer with functional
USB port running Windows 98/Me/2000
6. TCP/IP protocol stack

Installing the Cable Modem
Place your DOXport 1110 cable modem in an area that will not block any of its ventilation
holes. In order to hold the modem in an upright position (as shown below), use the included
stand.
Figure 3 shows the rear panel ports for Ethernet, USB, Power, and RF (cable).

Installing the Cable Modem 3
The setup sheet provided in your package and/or on the CD provides an illustrated step-by-
step procedure for setting up your modem. To summarize:
1. Make sure all “Before you start” requirements are met.
2. Look at the label on the bottom of the cable modem. This label shows the serial
number, the MAC (Media Access Control) address of your cable modem, and
the MAC address of the USB port. These numbers are unique to your modem.
Write them in the spaces below; you may need them for installation and future
reference. The CATV network uses the MAC addresses to communicate with
your modem.
Serial number _________________________
Modem MAC address___________________
USB MAC address _____________________
3. Connect the cable TV outlet to the input connector of a two-way CATV splitter
using an RG6 coaxial cable.
4. Connect a coaxial cable from one of the output connectors of the splitter to the
CATV port on the cable modem rear panel. The other output connector on the
splitter may be connected to other devices, such as your television or VCR.
5. Connect your computer to the cable modem using the Ethernet or USB port.
If you use your computer’s Ethernet port:
a. Connect one end of the Ethernet cable to your computer’s Ethernet port.
b. Connect the other end of the Ethernet cable to the Ethernet port on the
modem (labeled “10/100”).
c. Connect the 15VDC power adapter to the power port on the cable modem
rear panel (labeled “DC”). Plug the adapter into a power outlet.
d. Your configuration should look like Figure 4.

TCP/IP and check your IP address in Windows.
Configuring TCP/IP
With the modem connected, make sure that you have your computer configured for TCP/IP
and check for an IP address. The following instructions are for Windows 98 using Ethernet. If
you are using a different operating system, or computer interface, refer to that system’s user’s
guide.
Perform the following steps:
1. On the Windows desktop, click Start.
2. Select Settings and then Control Panel from the pop-up menu. Double-click
the Network icon on the Control Panel window. The Network window
