    s Screen Trigger 
    When the projector is powered ON the screen  trigger output sends a low voltage trigger to 
    the screen controller and the screen will go down . When the projector is powered OFF the 
    screen trigger stops sending a low voltage tri gger to the screen controller and the screen will 
    go up. 
    Note: 
    To use this feature, you must turn  on the Screen Trigger function. See Screen 
    Trigger on page 94 for more information.  
     
    Note: 
    Screen controllers are supplied and  supported by screen manufacturers.  
     
    Note: 
    Do not use this jack for anything other  than intended use. Connecting the wired 
    remote control to the SC. TRIGGER Mini  Jack causes damage to the remote con-
    trol.

    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:

    server functions by specifying  http://192.168.73.1/index.html  for the address or the en-
    try column of the URL.
