Bootstrap loader; a small software program, stored in internal flash memory, that is responsible for loading the firmware or operating system.

A lighting fixture containing more than one controllable element, for example an LED batten consisting of a number of identical elements or pixels.

"Digital Addressable Lighting Interface"; an industry standard digital lighting control protocol.

"Dynamic Host Configuration Protocol"; a method of automatically assigning IP addresses.

USITT DMX512; an industry standard digital lighting control protocol.

The embedded operating system, stored in internal flash memory (not the Compact Flash Card).

Lighting instrument or luminaire.

A collection of fixtures or elements (pixels) within a fixture that provide a very useful shortcut for selecting and programming them together as one.

"Internet Protocol" address, in the form xxx.xxx.xxx.xxx, which specifies the unique address for networked equipment.

A two-dimensional array of fixtures such that each fixture, or element within a compound fixture, is mapped to a pixel of the array.

"Musical Instrument Digital Interface"; an industry standard communications protocol for musical instruments.

Any fixture that has control parameters beyond colour mixing (RGB, CMY etc) and intensity, typically an automated light.

Any networked device that can receive and transmit data, typically the Pharos LPC 1 or LPC 2, with more in development.

"Network Time Protocol"; a means of transmitting time signals over a computer network, used to set realtime clocks automatically to the correct time.

The Pharos of Alexandria was a lighthouse built in the 3rd century BC on the island of Pharos in Alexandria, Egypt to serve as that port's landmark, and later, as a lighthouse. With a height variously estimated at between 115 and 135 metres (383 - 440 ft) it was among the tallest man-made structures on Earth for many centuries, and was identified as one of the Seven Wonders of the World by Antipater of Sidon.

The basic building block that is placed on a timeline to define what a fixture, or group of fixtures, is to do. Roughly analogous to a cue.

"Remote Device Management"; a proposed extension to the USITT DMX512 protocol that allows for bi-directional communication with the fixture for remote configuration and diagnostics purposes.

EIA-232; an industry standard communications protocol for computing and telecommunications equipment.

EIA-485; an industry standard communications protocol for computing and industrial equipment.

The framework used to determine which presets are appiled to which fixtures, when and for how long. Roughly analogous to a cuelist.

A value that can be captured from an input string that is used to determine the outcome of an action.

A hardware device that monitors a microprocessor and automatically forces a reset in the event that the microprocessor has stopped responding.

A method of specifying which character(s) of an input string should be ignored as padding. Wildcards are also captured as variables and can be considered such if used to determine the outcome of an action.
