Global Configurator (GC) is a windows program that, based
on user input, creates a GlobalViewer (GV). GC requests
system information such as which devices you have and your
current list of IP addresses. With this information, GC creates
a GlobalViewer for your specific devices. GC also compiles the
event scripts and loads the GV and event scripts onto the box.
When using GC, the user must specify the port number for each
device (for attached devices to be controlled, they must be on
that port). In order for multiple IP-Link
®
boxes to appear in the
same GV, all the boxes must be configured at the same time,
using GC.
GlobalViewer (GV) is a set of Web pages (HTML, XML, JS)
and graphics that are loaded into the memory of an IPL T SF
unit. These pages provide an interface for control of devices
attached to the IPL T SF unit. They communicate with the
event scripts running on the box, 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 T SF box. GV is initially created
by GC; however, it is possible to edit the GV HTML, XML, and
JavaScript files outside of Global Configurator. This edited GV
is called “hard-coded” or manually generated GV.
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.
Hysteresis (deadband) is the lag that exists between the
responding parameter and the changing parameter.
Internet Protocol (IP) 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 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 Netmask is a 32-bit binary number (12 digit decimal number,
xxx.xxx.xxx.xxx) used on subnets (smaller, local networks) to
help the router determine which network traffic gets routed
internally to local computers and which network traffic goes out
on the Internet.
Media Access Control (MAC) 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 the Internet, a table (see ARP) relates the device’s
IP address to its corresponding physical (MAC) address on the
LAN.
