The Embedded HTML Page
The embedded Web page stored on the MultiConnect IP consists of normal ASCII text HTML
code, which can be generated using any HTML editing tool. The page can include scripts, links to
remote Web sites, graphic images, text files, etc.
A maximum 30 KB (uncompressed) of flash space for the OEM's Home Page and an additional
10 KB maximum memory is reserved for the device parameter list.
The OEM Web page must contain the Parameter Tags, which are the placeholders in HTML
files. These tags are replaced on the fly with real-time values when the page is sent to the
browser. The value of the parameter tags also can be changed through the browser in order to
configure the host through the MultiConnect IP.
The developer should ensure that the parameter values, which are to be replaced, are qualified
with %P<n>%.
Example:
<HTML>
--
--
--
--
Efficiency <input type="text" name = "P1" value = "%P1%">
--
--
</HTML>
In the above sample code segment, when the browser requests a page, the
with Parameter P1's value. This value is extracted from the serial device parameter file.

Post-Query is a built-in CGI script that will parse the new values set by the browser and
replace them in the http-host-param file. See the section entitled Parameters Manipulation
from the Browser for more technical information about the Post-Query CGI script.

The MultiConnect IP supports a user-defined CGI script, which performs host-specific
processing to the parameters configured by the remote Web browser.
