Y
Full reference threshold
is the point at which a device starts to operate at full
power.
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.
IEC power receptacle
is a standard power connector. The
IPL T PCS4i rear panel has four female IEC receptacles into
which devices are plugged in order to be monitored,
scheduled, and powered on and off by the PCS4i.
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 the Internet, a table (see ARP) relates the device’s IP address to its
corresponding physical (MAC) address on the LAN.
Ping
is a utility/diagnostic tool that tests network connections. It is used to
determine if the host has an operating connection and is able to exchange
information with another host.
Port number
is a preassigned address within a server that provides a direct
route from the application to the transport layer or from the transport layer
to the application of a TCP/IP system. The standard ports used are 23 for
Telnet and 80 for Ethernet.
Power level reference threshold.
(See
Reference threshold
.)
Reference threshold
is the point at which the power level (full or standby) at
which a device is operating changes. This threshold is recognized by the
IPL T PCS4, which can be configured to sound an alarm whenever a
connected device passes this threshold.
Receptacle
is a fitting connected to a power supply and equipped to receive a
plug. The IPL T PCS4 has four receptacles into which devices can be
plugged, enabling the PCS4 to monitor and schedule power for the
connected devices.
SIS (Simple Instruction Set)
commands are a set of commands developed by
Extron that allow control of the PCS4 via the keyboard of a PC with an
Ethernet connection. A minimal number of characters are used in these
commands and responses.
