Glossary

This section provides definitions of terms related to the IPL T CR48.

10/100Base-T — Ethernet that uses Unshielded Twisted Pair (such as UTP - CAT 5) cable, where the amount of data transmitted between two points in a given amount of time is equal to either 10 Mbps or 100 Mbps.

Address Resolution Protocol (ARP) — ARP is a protocol which assigns an IP address to a device based on the MAC or physical machine address of the device.

Contact Closure — An encapsulated switch containing two metal wires that serve as the contact points. When these contact points meet, it creates a complete circuit (for example, ports 1 through 4 to ground on the IPL T CR48).

Custom Web page — Any file that can be loaded into an IPL T CR48 and served by the unit’s internal Web server. A custom Web page can provide control of devices attached to the IPL T CR48 without use of the GlobalViewer® (GV) or Global Configurator (GC). This is true with or without an accompanying event script. Any number and size of graphics can be used, but if they are too large to fit on the IPL T CR48, you can write your Web page so that they can be served from another Web server. If you install Microsoft® Internet Information Services (IIS) on your desktop, you can serve any page on its hard disk. The IPL T CR48 functions like a small computer with a Web server — you can use it for various Web tasks.

DHCP — Dynamic Host Configuration Protocol (DHCP), which is a standardized communications protocol that enables network administrators to locally and automatically manage the assignment of IP addresses in a network for an organization.

Driver — A GC compatible package. It includes the event script that controls devices.

Ethernet — A network protocol that uses MAC addresses instead of IP addresses to exchange data between computers. Using ARP (see above), with TCP/IP support, Ethernet devices can be connected to the Internet. An Ethernet LAN typically uses unshielded twisted pair (UTP) wires. Ethernet systems currently provide transmission speeds of

10 Mbps or 100 Mbps.

Event script — A program that runs on an IPL T CR48 controller, and issues queries and commands to the attached devices. Event scripts are written in the “Extron C” language (*.sc), and compiled into an event script (*.evt). GC performs this compilation. The compiled result is loaded onto the IPL T CR48. The Extron C language is similar to ANSI C, with some differences. As long as event scripts are turned on, event scripts run continuously on the unit.

Global Configurator (GC) — 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, you 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® units to appear in the same GV, all the units must be configured at the same time, using GC.
