Extron electronic IPL T PC1i manual H, I, M, P, R

GlobalViewer (GV) A set of web pages (HTML, XML, JS) and graphics that are loaded into the memory of an IPL T PC1 interface. These pages provide an interface for control of devices attached to the IPL T PC1 interface. They communicate with the event scripts running on the device, and the event scripts issue the commands and queries. This communication between the web pages and the event scripts occurs through predetermined memory locations in the IPL interface. GV is initially created by Global Configurator (GC); however, it is possible to edit the GV HTML, XML, and JavaScript files outside of GC. This edited GV is called “hard-coded” or manually generated GlobalViewer.

H, I, M

HTTP	(HyperText Transfer Protocol) A web protocol, based on TCP/IP, that is used to fetch
	HyperText objects from remote web pages

IEC power receptacle

A standard power connector. The IPL T PC1i rear panel has a female IEC receptacle into which a device is plugged in order to be powered on and off by the PC1i.

IP	(Internet Protocol) The protocol or standard used to send information from one computer
	to another on the Internet
IP address	A unique, 32-bit, binary number (up to a 12 digit decimal number, nnn.nnn.nnn.nnn) 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

A 32-bit binary number (12 digit decimal number, nnn.nnn.nnn.nnn) 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 Code) A unique hardware number given to devices that connect to the
	Internet. When your computer or networking device (router, hub, interface, and so forth) is
	connected to a LAN or the Internet, a table (see ARP) associates the device IP address with
	its corresponding physical (MAC) address on the LAN.
P, R
Pass-through	Allows control systems to work with the IPL T PC1 interface, and provides a link between
	two ports.
Ping	A utility and 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	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	A connector on a power supply that is 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.
