L Operation Using an HTTP Browser
Overview
The  use  of  HTTP  server  functions  will  allow  control  of  the  projector  from  a  web  browser  without  the  installation  of 
special software. Please be sure to use “Microsoft Internet Explorer 6.x” 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 meth-
od 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 functions by specifying
    http://  /index.html
in the entry column of the URL.
NOTE:
When a password is set for [HTTP SERVER] from [SECURITY], the log-on screen will be displayed. Enter a user name and your 
password. 
• A user name must be between 1 and 16 alphanumeric characters.
• Password is the one assigned in [HTTP SERVER] of [SECURITY SETTINGS].
NOTE:
• The  display’s  or  button’s  response  can  be  slowed  down  or  operation  may  not  be  accepted  depending  the  settings  of  your  net-
work. Should this happen, consult your network administrator.
 The projector may not respond if its buttons are repeatedly pressed in rapid intervals. Should this happen, wait a moment and 
repeat. If you still can’t get any response, turn off and back on the\
 projector.
• Do not use the HTTP Server functions and PC Control Utility 3.0 included on the supplied CD-ROM. Using both at the same time 
may result in a connection failure or slow response.
Preparation Before Use
Make network connections and set up the projector and confirm that it is complete before engaging in browser op-
erations. (→ [NETWORK SETTINGS] on page 19)
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.
Handling of the Address for Operation via a Browser
Regarding  the  actual  address  that  is  entered  for  the  address  or  entered  to  the  URL  column  when  operation  of  the 
projector is via a browser, the host name can be used as it is when the host name corresponding to the IP address 
of  the  projector  has  been  registered  to  the  domain  name  server  by  a  network  administrator,  or  the  host  name  cor-
responding to the IP address of the projector has been set in the “HOSTS” file of the computer being used.
Example 1:  When the host name of the projector has been set to “pj.nec.co.jp”,
  http://pj.nec.co.jp/index.html
 is specified for the address or the entry column of the URL.
Example 2: When the IP address of the projector is “192.168.73.1”, access is gained to the 
  HTTP server functions by specifying
 http://192.168.73.1/index.html
 for the address or the entry column of the URL.
