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 A/V 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®. Custom Web pages can be loaded through the Web server File 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
•Host commands instruct the IP Link product to act or respond.
•Remote commands instruct an A/V product (for example, a switcher or projector) to act or respond through an IPL T S unit.
When a Web page is requested, the Web server removes the SSI and replaces it with the answer to the SIS command within quotes.
