A-5 IPL 250 • Reference Material
Cables
Use the cables listed below for connecting an IPL 250 to accessories such as relay
switches or communications ports:
CTL Series (Comm-Link) cables Part number
CTLP/1000 plenum (1000 feet/300 meters) 22-119-03
CTL/1000 non-plenum (1000 feet/300 meters) 22-148-03
N These cables are also available in 500 foot (150 m) lengths.
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 file that can be loaded into an IPL 250 and served by
the MLC’s internal Web server. The IPL 250 can be used for various Web-
based tasks. The Web page provides a way to control the IPL and other
devices attached to it without use of the software, and with or without an
accompanying event script. Any number and size of graphics can be used. If
they are too large to fit in the IPL 250’s nonvolatile memory, Web pages can be
created so that they can be served from another Web server using Microsoft
Internet Information Services (IIS).
DHCP (Dynamic Host Configuration 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 IP Link product. Event scripts are written
in the “Extron C” language (.sc), and compiled into a machine-readable event
script file (.evt). The Global Configurator program performs this compilation
and uploads the compiled event file onto the IPL 250. 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 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 — See subnet mask.
