IP Connection Testing
To check that the IP configuration is correct and both the PC and the Opera 4 IP are on the
same network -
At the PC, from Windows -
• Go to <Start>
• Select <Run>
A window prompting the user to open a program will appear -
• Type "command" (or "cmd" in some cases for Windows 2000) in the white field. The
MS-DOS window opens with the following prompt - C:\_
• Type "ipconfig" at the cursor.
The details of the IP configuration of the PC will appear on the window - e.g.
Windows IP Configuration -
IP Address ......................... 192.168.1.251
Subnet Mask ....................... 255.255.255.0
Default Gateway ................ 192.168.1.254
Make sure that the configuration that appears on your PC is correct.
In order to test the IP connection between the PC and the Opera 4 IP, type "ping", followed by
the IP address of the Opera 4 IP. To test for the example shown above, type -
Ping 192.168.1.250
The PC will ping the system with 32 bytes of data and report the results. If the IP connection is
correct, the results should state -
Packets: Sent=4, Received=4, Lost=0 (0% Lost).
If the IP connection is incorrect, check again that the system and the PC are in the same IP
address range and that the cabling connections are correct.
