t Operation Using 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. Pl ease be sure to use “Microsoft Internet Ex-
plorer 4.x” or a higher version for the web  browser. (This device uses “JavaScript” and 
“Cookies” and the browser should be set to a ccept 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 functions by specifying the following address in the 
entry column of the URL: 
http://  /index.html 
http://  /lanconf.html 
Note: 
The display or button responses can be sl owed down or operation may not be ac-
cepted 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 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. 
Preparation Before Use 
Make network connections, set up the projecto r and confirm that it is complete before 
engaging in browser operations (see 
LAN Settings on page 91  for more information). 
Operation with a browser that uses a proxy server may not be possible depending on 
the type of proxy server and the setting met hod. Although the type of proxy server will be 
a factor, it is possible that items that  have actually been set will not be displayed de-
pending on the effectiveness of the cache, an d the contents set from the browser may 
not be reflected in operation. It is recommend ed 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 enter ed for the address or entered to the URL col-
umn 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 regis-
tered to the domain name server by a  network administrator, or the host name 
corresponding to the IP address of the projec tor 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:
