 Network and Alert Mail Settings by Using an HTTP Browser
Overv ew
Connecting the projector to a network allows the projector to send an alert mail that informs the user that the lamp 
has reached the end of its life or an error has occurred.
The IP address and subnet mask of the projector can be set on the Network Setting screen of the web browser 
by using an HTTP server function. Please be sure to use “Microsoft Internet Explorer 6.0” or a higher version for 
the web browser. (This device uses “JavaScript” and “Cookies” and the browser should be set to accept these 
functions. The setting method will vary depending on the version of browser. Please refer to the help files and the 
other information provided in your software.)
Access is gained to the HTTP server function by starting the Web browser on the computer via the network con-
nected to the projector and enter the following URL.
•
  Network Setting
 
http:///index.html
•
  Alert Mail Setting
 
http:///lanconfig.html
Example :
  Network Setting
 
http://192.168.0.10/index.html
 Alert Mail Setting
 
http://192.168.0.10/lanconfig.html
TIP: The default IP address is “192.168.0.10”.
NOTE: 
•
  If the PROJECTOR NETWORK SETTINGS screen does not appear in the web brow\
ser, press the Ctrl+F5 keys to refresh your 
web browser (or clear the cache).
•
 
The display’s or button’s response can be slowed down or operation may not be accepted depending\
 the settings of your 
network. Should this happen, consult your network administrator.
 
The projector may not respond if its buttons are repeatedly pressed in r\
apid intervals. Should this happen, wait a moment and 
repeat. If you still can’t get any response, turn off and back on the\
 projector.
Preparat  on Before Use
Connect the projector to a commercially available LAN cable before engaging in browser operations. See page 22.
Operation with a browser that uses a proxy server may not be possible depending on the type of proxy server and 
the setting method. Although the type of proxy server will be a factor, it is possible that items that have actually 
been set will not be displayed depending on the effectiveness of the cache, and the contents set from the browser 
may not be reflected in operation. It is recommended that a proxy server not be used unless it is unavoidable.
