Device Control
Control of AV devices can be accomplished in several ways once the IPL T CR48 has been
connected and configured. These include web pages, Telnet, and direct port access.
Custom Web Pages
These pages can either be modified versions of the existing web pages or new web pages
developed in the field.
Web page development can be done with a website development tool such as Frontpage or
Dreamweaver. Custom web pages can be loaded with the web server
File Manager
(see Managing files on page 22).
Telnet (Port 23)
Telnet, short for Telecommunications Network, provides a way for you to connect to a
computer or server (in this case the IPL T CR48) on a network. Once connected via Telnet,
you can send ASCII serial commands (see
Programmer Guide for the Telnet and Web
Browser on page 23) to control devices connected to the IPL T CR48.
