IPL T CR48 • Communication and Control
Communication and Control, cont’d
Device Control
Control of devices may be accomplished in any of several ways
once the IPL T interface has been connected and congured.
These include Web pages, Telnet, and direct port access.
Custom Web pages
These pages can either be modied versions of the existing Web
pages, or new Web pages developed in the eld.
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 les” 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 interface) on a network. Once connected via Telnet, you can
send ASCII serial commands (see “Command/Response Table”
in this chapter) to control devices connected to the interface.
Accessing and using Telnet

Click Start, then Run, then type in “telnet” and click OK.
The Telnet program starts (see gure 4-11)
2. At the command prompt, type “open” and press Enter.

(The default IP address is 192.168.254.254, but it may have
been changed in the setup or conguration process. If it
was changed, use the new address.) Telnet defaults to port
