  1. To begin, ensure that your sign is plugged in the same network switch as the computer.

  2. Also, confirm that the computer has a static address that is not on the sign's default IP range.
  3. Navigate to the internet protocol TCP/IP properties section of your network adapter.
    1. Open "START" Menu.
    2. In Windows XP click on "RUN" and type "ncpa.cpl" (this is not case sensitive).  If using Windows Vista or 7 after hitting the "START" icon, type "ncpa.cpl" into the search bar above the "START" icon.
    3. Find the "Local Area Connection" then "right-click" on it. 
    4. Click on "Properties".
    5. In Windows XP you will double click on "Internet Protocol (TCP/IP)".  However, with Windows Vista and Windows 7 you will need to double click "Internet Protocol Version 4 (TCP/IPv4)".
  4. Verify that the radial next to "use the following IP address" is selected and that a static IP is entered.
    • If there is no static IP, set the static IP, subnet, gateway and DNS information according to what is found from double-clicking the network connection of concern (e.g. "Local Area Connection"), and click on the "Details" button (in Windows XP, the "Details" button is located on the Support tab).
  5. Click on "Advanced" near the bottom of the "Internet Protocol (TCP/IP) Properties" window.
  6. Click on "Add" under the IP addresses section at the top of the window.
  7. Enter an IP address and subnet mask that is on the secondary network you wish to communicate with.
  8. Click "add" on the "TCP/IP Address" window.
  9. Return to desktop.
  10. Click "OK" at the bottom of the "Advanced TCP/IP Settings" window.
  11. Click "OK" at the bottom of the Internet Protocol or Internet Protocol Version 4 Properties window.
  12. Click "OK" at the bottom of the Local Area Connections Window.
  13. Close the Network Connection window.
