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.
Address Resolution Protocol (ARP) 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 file that can be loaded into a System 5 IP switcher and
served by the switcher's internal Web server. The Web page provides a way
to control the switcher 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 fit in the
System 5 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 System 5 IP functions like a little computer with a Web
server—you can use it for various Web-based tasks.
DHCP is the Dynamic Host Configuration Protocol (DHCP), 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 package of commands that generates or is 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 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 runs on a System 5 IP and issues queries and
commands to the attached devices. Event scripts are written in the
"Extron C" language (.sc), and compiled into an event script (.evt). The
Windows-based System 5 IP control program performs this compilation. The
compiled result (.evt) is loaded onto the System 5 IP. The Extron C language
is similar to ANSI C, with some differences. As long as event scripts are
turned on, event scripts run continuously on the box.
HTTP is an acronym for the HyperText Transfer Protocol (HTTP), 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 identifies 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 traffic gets routed internally (within the
subnetwork) to local computers and which network traffic goes out to the rest
of the network or the Internet.
Media Access Control (MAC) 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
