Word	Description
Adapter	An accessory used for interconnecting non-mating devices or converting an existing device for modified use.
Airgap	Airgap is a feature that all UL Listed Dimmers must contain. It is a method for disconnecting all power to a load: Lightolier, PCS and OnQ ALC: Push Hard on the bottom of the dimmer paddle until it clicks Leviton HC series dimmers: Pull on the plunger in the lower left corner X10 and X10 Pro: there is a horizontal slide under the paddle / button
Ballast	A transformer that steps down AC line voltage to voltage that can be used by fluorescent or other types of lighting. Ballasts may be electromagnetic or electronic.
CFL	Compact Fluorescent Lighting
Contactor	High capacity relay.
Cord Connector	A portable receptacle designed for attachment to or provided with flexible cord, not intended for fixed mounting.
Dips	Small switches for changing settings on a ciruit board.
Ethernet to Wireless Bridge	A device that connects to an Ethernet port on another device and converts wired Ethernet into wireless Ethernet (802.11b or 802.11g).
Flanged Inlet	A plug intended for flush mounting on appliances or equipment to provide a means for power connection via a cord connector.
Flanged Outlet	A receptacle intended for flush mounting on appliances or equipment to provide a means for power connection via an inserted plug.
Floating Extension	Virtual extension numbers can be assigned to resources to make them as easily accessible as extensions. These numbers are referred to as "floating extension numbers". Examples: Extension Groups, Voice Mail, External Paging, Etc.
Fluorescent Starter	A device with a voltage-sensitive switch and a capacitor that provides a high-voltage pulse to start a fluorescent lamp. Rated in watts.
GFCI	Ground Fault Circuit Interupter. A system that shuts down the protected electric circuit -- opens it -- when it senses an unexpected loss of power, presumably to ground. GFCI protection devices constantly monitor and compare the amount of power flowing from the panel on the hot or phase wire and the amount returning on the neutral wire. Any time the returning power drops even slightly below the amount being supplied, the protection device will trip and open the circuit
Hook/Flash	The hook/flash button is a momentary "hang up" of the phone receiver
Lampholder	A device with contacts that establishes mechanical and electrical connection to an inserted lamp.
Low Voltage	Any voltage that is below 48 volts.
Network	A system of connected devices such as computers
P.D.A.	(Personal Digital Assistant) A handheld computer that serves as an organizer for personal information. It generally includes at least a name and address database, to-do list and note taker. PDAs are pen based and use a stylus to tap selections on menus and to enter printed characters. The unit may also include a small on-screen keyboard which is tapped with the pen. Data are synchronized between the PDA and desktop computer via cable or wireless transmission.
PCMCIA	Also known as "PC Cards," PCMCIA Cards are used to attach modems, network adapters, sound cards, radio transceivers, solid state disks and hard disks to a portable computer. Early laptop computers were more limited than their desktop counterparts, and the first PCMCIA Cards provided necessary expansion. Today, PCMCIA Cards still serve the same purpose, adding new or missing functionality to existing machines.
Plug	A device with male contacts intended for insertion into a receptacle to establish electrical connection between the attached flexible cord and the conductors connected to the receptacle.
Portable Station	A wireless phone from Panasonic. These phones are used with Panasonic's Cell Stations (CS) that are compatible with the KX-TAW848 and the KX-TDA series systems.
R-Net	The Russound CAV6.6 controller uses a comprehensive communications protocol to interface with the various devices in the system, that is extended to the RS232 ports on its front and rear panels. Through these ports, virtually all aspects of the system operation can be performed. Multiple CAV6.6 units can be stacked and "addressed" using R-Net.
Receptacle	A device with female contacts designed for fixed installation in a structure or piece of equipment and which is intended to establish electrical connection with an inserted plug.
Source	1. Any device that has a composite video and/or left and right audio outs that can be used as inputs. 2. Any device that has an output that can be used as an input.
Switch	1. Technically speaking a switch is an on/off device and a dimmer alters the average voltage output to brighten/dim a load. Often the term 'switch' is used interchangeably with a dimmer when discussing a control point on the wall. 2. An Ethernet connection module for tying together multiple PCs
USB	(Universal Serial Bus) A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, scanner, printer and telephony devices. It also supports MPEG-1 and MPEG-2 digital video. USB has a maximum bandwidth of 12 Mbits/sec (equivalent to 1.5 Mbytes/sec), and up to 127 devices can be attached. Fast devices can use the full bandwidth, while lower-speed ones can transfer data using a 1.5 Mbits/sec subchannel. USB's hot swap capability allows everything to be plugged in and unplugged without turning the system off. USB ports began to appear on PCs in 1997, and Windows 98 was the first Windows to support it natively. USB 2.0, widely known as Hi-Speed USB, dramatically increases capacity to 480 Mbits/sec.
Wallplate	A plate designed to enclose an electrical box, with or without a device installed within the box.
