Device Control

Control of devices may be accomplished in any of several ways once the IPL T 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 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

1.Click Start, then Run, then type in “telnet” and click OK. The Telnet program starts (see figure 4-11)

2.At the command prompt, type “open” and press Enter.

3.At the <to> prompt, type the IP address of the IPL T 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.
