 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 4.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 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
    http://  /index.html
in the entry column of the URL.
NOTE:
•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 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 opera-
tions. (→ [LAN Mode] on page 89)
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 corre-
sponding 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.
