Symptom

Cannot connect the system to a network. (Continued from the preceding page)

Corrective action

Checking for presence in a LAN

<Using a command from PC to search for the DS-L1 in a LAN> Check network connections by using the “ping” command.

For Windows, select [Start] - [Programs] - [Accessories] - [MS-DOS Prompt] in that order, and enter the command from the prompt given below.

BrowserCannot access the camera from a browser.

Windows 95/98:

PC MS-DOS prompt

Windows NT/2000/XP:

Command prompt

Mac OS X, select [Macintosh HD] - [Applications] - [Utilities] - [Terminal], and enter the command from the TERMINAL screen.

Example: If the IP address of the DS-L1 is 192.168.10.2

Enter the command “ping 192.168.10.2” and hit the return key.

If a message such as “Reply from 192.168.10.2: bytes=32 time…” is returned, it means that the presence of the DS-L1 in a LAN is recognized. The problem thus lies in the settings of the DS-L1 or PC. If a “Request timed out” message is returned, the presence of the DS-L1 is not recognized. Check the cables, hub connections, and the network settings of the PC (e.g., the IP address). Also check that the PC is connected to a LAN (by using a browser or the ping command).
