Communication and Control, cont'd
Pacing and handshaking are not supported on captive
screw connectors.
All of the bidirectional serial ports are completely software
configurable. Baud rates can be set up to 115Kbs. Using the
Simple Instruction Set (SIS) commands found in the Command/
Response Table for Simple Instruction Set later in this chapter, these
ports can be configured to control most serial devices. Once a
port is configured and properly cabled to the controlled device,
serial commands can be issued to the port from a Web page,
Telnet connection, or by using the advanced scripting capability
built into the IP Link product family.
Communication with the Interface
Web server
The on-board Web server is displayed as a set of default Web
pages which can be accessed via a Web browser. These pages
are the primary means of communication with, and control
through, the IPL T interface. Web browsers such as Netscape
Navigator (version 6.0 or higher), or Internet Explorer (version
5.5 or higher) can be used, but if using Internet Explorer, you
must also have Microsoft Script (version 5.6 or higher).
The PC used to access the Web server must have a connection in
common with the IPL T interface. In other words, both the unit
and the PC should be connected to your local intranet or the
Internet.
If you have established passwords for the interface, you will be
shown a Password window when your browser accesses the IPL
T unit (but not when you initially access the Web server, since
no passwords have been established). Your level of control over
the interface will depend on the password you enter in this
password screen. If you enter the administrator's password, you
will have control of all matters of configuration. If you enter a
user password, you will be restricted to control of A/V devices
and viewing status.

Establishing or changing system or port settings
The System Settings screen is used to initially configure or

required to change system settings if your network changes, or
if port settings change as you add or change display devices or
switchers.
To configure system or port settings:

screen (figure 4-10) is displayed.
