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) 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 an IPL T SF
box and served by the IPL T SF’s internal Web server. A custom
Web page can provide control of devices attached to the IPL T SF
without use of the GlobalViewer
®
(GV) or Global Configurator
(GC). 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 SF, 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 SF
functions like a little computer with a Web server—you can use
it for various Web tasks.
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 and 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 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 an IPL T SF box,
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). GC performs this
compilation. The compiled result (.evt) is loaded onto the IPL T
SF box. 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 unit.
Floating is the condition of a device or circuit that is not
grounded and not tied to any established potential.
