Glossary
10/100Base-T is Ethernet which uses unshielded twisted pair (UTP - Cat 5, etc.)
cable, where the amount of data transmitted between two points in a given
amount of time is equal to either 10 Mbps or 100 Mbps.
ARP (Address Resolution Protocol) is a protocol which assigns an IP address to a
device based on the device’s MAC or physical machine address.
Custom Web page is any fi le that can be loaded into an MLC 226 IP and served
by the MLC’s internal Web server. The Web page provides a way to control
the MLC and other devices attached to it without use of the software. 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 fi t in the MLC 226 IP’s
nonvolatile memory, you can create Web pages 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
MLC 226 IP functions like a little computer with a Web server—you can use it
for various Web-based tasks.
DHCP (Dynamic Host Confi guration Protocol) 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 software package that controls the interface between the controller and
peripheral devices.
Ethernet is a network protocol that uses MAC addresses instead of IP addresses
to exchange data between computers. Using ARP (see above) 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 controls an MLC 226 IP. Event scripts are written in
the “Extron C” language (.sc), and compiled into an event script (.evt). The
Global Confi gurator program performs this compilation and uploads the
compiled event fi le onto the MLC 226 IP. The Extron C language is similar to
ANSI C, with some differences. As long as event scripts are turned on, they
run continuously on the unit.
HTTP (HyperText Transfer Protocol) is a Web protocol based on TCP/IP that is
used to fetch HyperText objects from remote Web pages.
IP (Internet Protocol) is the protocol or standard used to send information from one
computer to another on the Internet.
IP address is a unique, 32-bit, binary number (12 digit decimal number, xxx.xxx.
xxx.xxx) that identifi es each device or device port (an information sender
and/or receiver) that is connected to a LAN, WAN, or the Internet. IP
addresses can be static (see static IP) or dynamic (see DHCP).
IP net mask/subnet mask is a 32-bit binary number (12 digit decimal number,
xxx.xxx.xxx.xxx) used on subnets (smaller, local networks) to help routers
determine which network traffi c gets routed internally (within the
subnetwork) to local computers and which network traffi c goes out to the rest
of the network or the Internet.
MAC (Media Access Control) Address is a unique hardware number given to
devices that connect to a network such as the Internet. When your computer
or networking device (router, hub, interface, etc.) is connected to a LAN or the
Internet, a table (see ARP) relates the device’s IP address to its corresponding
physical (MAC) address on the LAN.
