Glossary, cont’d Glossary 10/100Base-T is Ethernet which uses Unshielded Twisted Pair (UTP - CAT 5, etc.) 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 device’s MAC or physical machine address. Custom Web page is any file that can be loaded into an IPL T SF box and served by the IPL T SF’s internal Web server.
-
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).
-
Glossary, cont’d Pass-through allows control systems to work with the IPL T SF unit and provides a link between two ports. Ping is a utility 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.
