IPL T SF Series • Communication and Control
A/V Device Control
Control of A/V devices may be accomplished in any of several
ways once the IPL T SF interface 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 are loadable with the Web server File Manager (see
“Managing files” earlier in this chapter).
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 SF interface) on a network. Once connected via Telnet,
you can send ASCII serial commands (see the “Programmer’s
Guide for the Telnet and Web Browser” earlier in this chapter)
to control devices connected to the interface through both serial
ports. Telnet only works in RS-232 mode.
Accessing and using Telnet
1. Click Start, then Run and type “Telnet”. Click OK. The
Telnet program starts (see figure 4-31).
2. At the command prompt, type “open” and press Enter.
3. At the < to > prompt, type the IP address of the IPL T SF
unit. (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.
