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 specic devices. GC also compiles the
event scripts and loads the GlobalViewer 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 GlobalViewer, all the boxes must be congured at
the same time, using Global Congurator.
GlobalViewer (GV) is a set of Web pages (HTML, XML, JS) and
graphics that are loaded into the memory of an IPL box. These
pages provide an interface for control of devices attached to the
IPL. 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 box.
GlobalViewer is initially created by Global Congurator (GC);
however, it is possible to edit the GlobalViewer HTML, XML,
and JavaScript les outside of GC. 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.
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 identies 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 trafc gets routed
internally to local computers and which network trafc 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.
Pass-through allows control systems to work with the IPL and
provides a link between two ports.
