If the main page does not launch the IP Address is most likely incorrect Correct the IP Address and try
again If you do not know the IP Address use the following procedure:
1) Open an MS-DOS Command Prompt
2) Type ipconfig and press Enter
3) Note the IP Address (The previous example was 192 168 0 100)
4) To test the communication between the PC and the unit type ping (###.###.#.###) in the
prompt and press Enter The (###.###.#.###) is the IP Address of the unit you used in step 5 of
network configuration, which is 192.168.0.100 by default If the device is connected to the network
the ping will show a response If you get no response check the crossover cable
