Customization
In the IPL T S interface series of products, varying degrees of customization are possible.
Custom web pages allow you to create customized web pages to control your AV devices.
Server Side Includes (SSI) makes it possible to obtain information from the unit and to display
it on web pages. URL encoding allows you to send information and commands to the unit to
change its configuration or to receive feedback.
Custom web Pages
These pages can be either modified versions of the existing default web pages on the web
server, or new web pages developed in the field.
web page development can be done with a web site development tool such as FrontPage
or Dreamweaver
Management page.
Server Side Includes (SSI)
SSIs are HTML commands that direct the web server to dynamically generate data for a
web page whenever requested. SSIs typically use the Extron Simple Instruction Set (SIS) to
communicate commands to the products or to attached control devices. Using SSIs, you
can design and display custom pages with the
IPL T S information provided by the SIS commands.
The basic format for an Extron SSI command is:
<!—#echo var="x"—>
Where x is the SIS command to be executed.
The SIS instructions sent to IP Link-enabled products fall into two categories: host or
remote.

When a web page is requested, the web server removes the SSI and replaces it with the
answer to the SIS command within quotes.

Host commands instruct the IP Link product to act or respond.
Remote commands instruct an AV product (for example, a switcher or projector) to act
or respond through an IPL T S unit.
