Extron Electronics IPL T CR48 - Manual (Page 39)

Device Control
Control of A/V 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 Web site development tool such as Frontpage
or Dreamweaver. Custom Web pages can be loaded with the Web server File Manager
(see
Managing files earlier in this section).
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’s Guide for the Telnet and Web
Browser earlier in this section) to control devices connected to the IPL T CR48.
Accessing and using Telnet
1. From the Windows desktop, click Start, then Run.
2. In the Run dialog box, type Telnet.
3. Click OK. The Telnet program starts ( figure 22 ).

4. At the command prompt, type open and press Enter on the keyboard.
5. At the <to> prompt, type the IP address of the IPL T CR48. (The default IP address is
192.168.254.254, but it may have been changed in the setup or configuration process.
If it was changed, use the new address.) Telnet defaults to port 23.
