IP address is a unique, 32-bit, binary number (up to a 12 digit decimal number,
xxx.xxx.xxx.xxx) that identifies each sender and each receiver of information
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.
MAC (Media Access Control) Address is a unique hardware number given to
devices that connect to the Internet. When your computer or networking
device (router, hub, interface, etc.) is connected to a LAN or the Internet, a
table (see ARP) associates the device’s IP address with its corresponding
physical (MAC) address on the LAN.
Pass-through allows control systems to work with the IPL T PC1 interface, and
provides a link between two ports.
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.
Receptacle is a fitting connected to a power supply and equipped to receive a
plug. The IPL T PC1 has one receptacle into which a device can be plugged,
enabling the PC1 to power the connected device on and off.
SIS (Simple Instruction Set) commands are a set of commands developed by
Extron that allow control of the PC1 via the keyboard of a PC with an
Ethernet connection. A minimal number of characters are used in these
commands and responses.
SMTP (Simple Mail Transfer Protocol) is an Internet standard for e-mail exchange
across systems/networks on the Internet.
Standby reference threshold is the point at which a device starts to operate at
standby power.
Static IP refers to an IP address that has been specifically (instead of dynamically—
see DHCP, on page A-5) assigned to a device or system in a network
configuration. This type of address requires manual configuration of the
actual network device or system and can be changed only manually or by
enabling DHCP.
Subnet. See Subnetwork.
Subnet address is the portion of an IP address that is specifically identified by the
subnet mask as the subnetwork.
Subnet mask is a 32-bit address mask used in IP to identify the bits of an IP address
that are used for the subnet address. Using a mask, the router does not need
to examine all 32 bits, only those selected by the mask.
Subnetwork is a network that is part of a larger IP network and is identified by a
subnet address. Networks can be segmented into subnetworks to provide a
hierarchical, multilevel routing structure.
