Glossary
10/100Base-T is Ethernet that uses Unshielded Twisted Pair (UTP - CAT 5, etc.)
cable, on which the amount of data transmitted between two points in a given
amount of time is equal to either 10 Mbps or 100 Mbps.
Address Resolution Protocol (ARP)
is a protocol that assigns an IP address to a
device based on the device’s MAC or physical machine address.
Custom Web page
is any file that can be loaded into an IPL T S interface and
served by the unit’s internal Web server. A custom Web page can provide control
of devices attached to the unit without use of Global Configurator (GC) or
GlobalViewer ® (GV). This is true with or without an accompanying event script.
Any number and size of graphics can be used, but if they are too large to fit on the
IPL T S interface, you can write your Web page so that they can be served from
another Web server. If you install Microsoft ® Internet Information Services (IIS) on
your desktop, you can serve any page on its hard disk. The IPL T S unit functions
like a little computer with a Web server—you can use it for various Web tasks.
DataViewer
allows you to send ASCII or hexadecimal commands to an Extron
IPL T S interface and view the device’s responses. You can configure the data
display in several ways, including selecting the text color, text font, and whether to
view commands and responses in separate panes within the DataViewer window.
The software can save the command/response data as a text file (.txt) or as an
HTML file that preserves some of the display formatting.
Default Web pages
are a set of preloaded Web pages that can be accessed via
a standard Web browser. These pages are a primary means of initial setup for
IP Link ® products and a way to change their settings. 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).
DHCP
is the Dynamic Host Configuration Protocol (DHCP), which is a
standardized communications protocol that enables network administrators
to locally and automatically manage the assignment of IP addresses in an
organization’s network.
Driver
is a GC compatible package. It includes the event script that controls
devices.
Ethernet
is a network protocol that uses MAC addresses instead of IP addresses
to exchange data between computers. Using ARP (see Address Resolution
Protocol), with TCP/IP support, Ethernet devices can be connected to the Internet.
An Ethernet LAN typically uses unshielded twisted pair (UTP) wires. Ethernet
systems currently provide transmission speeds of 10 Mbps or 100 Mbps.
Event script
is a program that runs on an IPL T S interface, and issues queries and
commands to the attached devices. Event scripts are written in the “Extron C”
language (as .sc files), and are compiled into event scripts using GC. The results are
compiled as .evt files and loaded onto the IPL T S device. The Extron C language
is similar to ANSI C, with some differences. As long as event scripts are turned on,
they run on the device continuously.
Global Configurator (GC)
is a Windows ® program that, based on user input,
creates the GlobalViewer pages. Global Configurator requests system information
such as which devices you have and your current list of IP addresses. With this
information, GC creates a GV page for your specific devices. GC also compiles
the event scripts and loads the GV pages and event scripts onto the device. When
using GC, the user must specify the port number for each device (for attached
devices to be controlled, they must be on that port). In order for multiple IP Link ®
devices to appear in the same GV page, all devices must be configured at the same
time using GC.
