Easy III communicates with the PC over an Ethernet link. A dedicated Ethernet network card must be installed in the PC, and the card must be configured to a specific IP address (192.168.113.66) to communicate correctly. Connecting to a local area network will require a second network card. To configure the IP address in a Windows 7 or Windows XP operating system:

Configure the Network Card for Windows 7:

1. Click the Start Orb.
2. Click on the Control Panel.
3. Change the “View:” to “Large Icons” or “Small Icons.” Do not use “Category View.”
4. Click on “Network and Sharing Center.”
5. Then click on “Change Adapter Settings” in the left-hand task pane. This will show all the network connections available on the computer.
6. Right-click on the LAN or High-Speed Internet connection that will be used to communicate to the base unit and select “Properties.”
7. Uncheck all the protocols in the list except for the Internet Protocol Version 4 (TCP/IPv4).
8. Then double-click on that protocol and change the radial button from “Obtain an IP address automatically” to “Use the following address.”
9. Input the default Cadwell® IP address. It is 192.168.113.66. The default Subnet Mask can be used of 255.255.255.0.
10. Once those addresses are added click on the Advanced button in the bottom right-hand corner of the screen. Click on the WINS tab and uncheck the “Enable LMHOSTS lookup” check box and change the NetBIOS setting from Default to “Disable NetBIOS over TCP/IP.”
11. Click OK three times to get back to the network connections page.
12. Once again, right-click on the LAN or High-Speed Internet connection that will be used to communicate to the base unit and click on “Properties.
13. Click on the Configure button in the upper left corner.
14. Click on the Advanced Tab then select the “Speed and Duplex” listing. It might also be displayed as “Media Type, Connection Type or Link Speed & Duplex.” Some Windows 7 systems will have a Link Speed tab.
15. Click the drop down list on the value right and select 10 Mbps Full Duplex.
16. Click on the Power Management tab. Deselect the “Allow the computer to turn off this device to save power” check box and then click OK. Note not all network cards will have a power management tab.
17. Right-click on the LAN or High-Speed Internet connection that will be used to communicate to the base unit and click on “Rename.”Type in Easy III Amplifier and press Enter.

Configure the Network Card for Windows XP:

1. If necessary, install a network card in the computer. Follow the network card’s manufacturer’s instructions.
2. Log in as a user with administrative rights.
3. From the Windows desktop, open the Start menu.
   1. Open the Control Panel and open Network and Internet Connections.
   2. Click on Network Connections. A separate icon for each network card installed will be displayed. By default, each is named “Local Area Connection.”
   3. Rename the network card used to connect to the Easy III hardware. Do so by right-clicking on the icon and select Rename, then typing a new name, such as “Easy III.”
4. Right-click over the renamed network connection icon.
   1. Select Properties
   2. Remove checkmarks next to everything except Internet Protocol (TCP/IP).

5. Click the Configure button.
   1. Under the Advanced tab, select your link speed or media type, and change the value to 10 Mbps Full Duplex.
   2. Under the Power Management tab, remove the checkmark next to “Allow computer to turn off this device to save power.”
   3. Click the OK button.
