Command Line Interface and Application Examples for Multi-Tech Systems, Inc. IP Modules (S000368F) 102

Monitoring and Configuring the Host

through a Browser

If you have successfully completed the preceding configuration sections and completed the uploading, you are now

ready to View, Monitor, and Configure the Host through the Web browser.

In order to view the device home page, enter the IP Address of the IP module into the URL Address bar.

Example: http://192.168.2.1

The IP address 192.168.2.1 corresponds to the IP address of the IP module.

Depending upon the configuration selected under set ip http-page <default/serial>, the appropriate page is

displayed.

• If the http-page is set to default, the index.HTML page displays or

• If the http-page is set to serial, the OEM’s customized Web page http-s0.HTML displays.

Technical Information

This section describes additional details and implementation suggestions related to the IP module.

Parameter Value Display on the Fly

The HTML file can be any valid HTML file. However, it should be ensured 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 code segment, when the browser requests a page, the %P1% is replaced with Parameter P1's

value. This value is extracted from the serial device parameter file (http-host-param).

Parameter Value Manipulation from the Browser

To update a parameter from the browser, key in the new values and click the Submit button.

The Submit button in turn invokes the POST command as shown below.

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.

Should you need to update the newly set parameters in the http-host-param file, include the /cgi-bin/post-

query path in the ACTION field of your HTML file. The rest is set by the Post-Query script.

Serial Device Parameter Updating Process

The serial device probes/polls the IP module for newly configured parameter values from the browser.
