However, before getting started, it is important for you to read the following information. 4.1.1 Before Installing 4.1.2 Building Requirements This unit will only operate in buildings utilizing coaXmedia Internet Access Solutions. 4.1.3 PC Requirements The SD220 / SD221 Access Appliance requires the use of a Network Interface Card installed in your PC; if you PC does not have a Network Interface Card, one must be installed before you can use the Access Appliance. Many computer retail stores and service centers can perform this task, if you require assistance. 4.1.4 Review the Safety Recommendations It is important to review the Safety Recommendations to insure the proper installation and operation of your Access Appliance. See the Safety Recommendations Section of this Users Guide. 4.1.5 Gather Tools Although most installations do not require any special tools, it may be necessary to use a 7/16 wrench or pliers to loosen an existing coax cable connection on a TV or CATV wall outlet. It is also desirable to lightly tighten all coax cable connections associated with installing the Access Appliance to insure solid, reliable connections; this can be done with a wrench, with pliers or by hand. Users Guide 9 SD220 / SD221 Access Appliance Select Location The first aspect of installing your new Appliance will be selecting a CATV outlet that is located near your computer. When making your selection, consider where you use your PC/laptop and the distance between that location and the CATV outlet. Although coaxial cables are provided with your Appliance, they may not be long enough for your installation;

if this is the case, longer cables can be obtained at a local store (RG-6 or RG-59 with F-type connectors). 10 Users Guide SD220 / SD221 Access Appliance 4.2 Connecting the Access Appliance This illustration diagrams the series of steps involved in connecting the parts together. Many parts have labeled connectors; those labels are in bold type. Two pieces of cable come packaged with the appliance; they are referred to as the provided cables.

Plug it into the diplex-filters TV connector

Use the 8 ft coaxial cable

(provided) to connect from the diplex-filters X connector to the Access Appliances RF port

Unplug the TV (VCR) cable from the rooms cable outlet

Use the 2 ft. coaxial cable (provided) to connect from the diplex-filters IN connector to the wall outlet

Plug the transformer cord into the Access Appliance s PWR connector

With all other connections secure, plug the transformer into the wall power outlet

Use the provided PC cable to connect from the Access Appliance connector labeled ETHERNET to the appropriate connector at the back of the computer Note: To ensure proper operation and UL compliance of product in the USA, use only the approved power supply included. Users Guide 11

Connect telephone to line 1 or line 2. SD220 / SD221 Access Appliance Turn off power to the computer and TV (or VCR) before connecting up the cables as a precaution. It is recommended to disconnect them from the wall power outlets. 4.3 Step by Step 1 Disconnect the TV from the CATV Outlet Locate the cable connecting your TV (or VCR) to the wall cable TV/CATV outlet. Unscrew the end from the wall connector. Leave the other end connected to the TV/VCR. If you arent using a TV in the room, just skip this step. 2 Connect the TV to the Diplex-Filter Connect the end of the coaxial cable that was unscrewed from the TV/CATV outlet to TV port of the included diplex-filter. If a TV or other device is not being used, leave the TV port unconnected. Do not substitute a generic cable splitter for the provided diplex-filter; although doing so will not damage the TV or Access Appliance, the diplex-filter improves the Appliances operational reliability If you are not connecting to a TV in the room, you should use the provided diplex-filter, leaving the TV connector unconnected. If you use one or more cable splitters in the room, you may continue to use them; however, you should install the diplex-filter so that it is the first device connected to the TV/CATV outlet. 3 Connect the Diplex-Filter to the CATV Outlet a) Locate the shortest coaxial cable included with the Access Appliance and connect one end to the IN port of the diplex-filter. b) Connect the loose end of that coaxial cable to the CATV wall Outlet. 4 Connect the Access Appliance to the Diplexer a) Locate the remaining coaxial cable included with the Access Appliance and connect one end to the X port of the diplex-filter. 12 Users Guide SD220 / SD221 Access Appliance b) Connect the loose end of that coaxial cable to the RF port of the Access Appliance. Make sure are all connections are secure; if necessary, use a wrench or pliers to lightly tighten the connections. 5 Connect analog telephone set a) Connect the cord from the analog telephone set to either RJ-11 connector on the back of the SD220 access appliance. Do not attempt to insert the supplied phone cable into a dial-up modem or into the RJ-11 jack in your wall. Doing so could damage your modem port and/or the SD220 / SD221 SandDollar. 6 Connect PC Cable a) Locate the Ethernet PC cable included with the Access Appliance and connect it to the Access Appliances Ethernet port. b) Connect the loose end of that cable into an active Ethernet port on your PC. If you PC does not have a Network Interface Card, one must be installed before you can use the Access Appliance. Many computer retail stores and service centers can perform this task, if you require assistance. PC Ethernet Port Do not attempt to insert the supplied Ethernet cable into a dial-up modem. Doing so could damage your modem port and/or the Ethernet cable. 7 Connect the Power Adapter to the Appliance Locate the included power adapter and connect the appropriate end to the PWR port on the Access Appliance. Users Guide 13 SD220 / SD221 Access Appliance 8 Apply Power to the Access Appliance Before plugging the adapter into the power outlet, consult these important notes:

Please check the voltage requirements printed on the power adapter before plugging it into an AC power outlet. If the power adapters input voltage specification does not match what is being provided at your AC outlet, contact your service provider or coaXmedia for a replacement. Power can now be applied to the Appliance by plugging the power adapter into a unused AC power outlet (on a wall, power strip, surge protector, or UPS). The P indicator on the Appliance front panel should light up when power is applied. (See also a description of the front panel lights on page 17.) Now that the Access Appliance setup has been completed, you can set up your computer to use the connection. 5 Configuring Your PC Now that all the necessary hardware connections have been made, your computers network configuration may need to be adjusted. Often when using the Ethernet connection, Internet Service Providers require your Ethernet card to be configured to obtain an IP address automatically (DHCP). Instructions for making the necessary adjustment can be found below, however your Internet service provider may supply you with additional instructions that should take precedence. Please refer to these instructions if supplied. 5.1 How to Configure your PC for DHCP The following DHCP configuration procedure applies to the following Operating Systems:
