 NOTE: The lamp life rating for any projector is a measure of brightness 
degradation only, and is not a specification for the time it takes a lamp to fail 
and cease light output. Lamp life is defined as the time it takes for more than 50 
percent of a lamp sample population to have brightness decrease by 
approximately 50 percent of the rated lumens for the specified lamp. The lamp 
life rating is not guaranteed in any way. The actual operating life span of a 
projector lamp will vary according to operating conditions and usage patterns. 
Usage of a projector in stressful conditions which may include dusty 
environments, under high temperatures, many hours per day and abrupt 
powering-off will most likely result in a lamp’s shortened operating life span or 
possible lamp failure.USB port: One USB slave for remote support.
RS232 port: One mini-DIN 6-pins for RS232 
communication. 
RJ45 port: One RJ45 connector for control of 
projector through network.
12V output: One 12V DC / 200mA max. relay 
output for driving automatic screen.
Lamp Philips 280W user-replaceable lamp (up to 2500 
hours in eco mode)

							76Glossary
Appendix: Glossary
ANSI LUMENS — A standard for measuring the brightness. It is calculated by 
dividing a square meter image into nine equal rectangles, measuring the lux (or 
brightness) reading at the center of each rectangle, and averaging these nine 
points.
A
SPECT RATIO — The most popular aspect ratio is 4:3 (4 by 3). Early television and 
computer video formats are in a 4:3 aspect ratio, which means that the width of 
the image is 4/3 times the height.
Brightness — The amount of light emitting from a display or projection display 
or projection device. The brightness of projector is measured by ANSI lumens.
Color Temperature — The color appearance of white light. Low color 
temperature implies warmer (more yellow/red) light while high color temperature 
implies a colder (more blue) light. The standard unit for color temperature is 
Kelvin (K).
Component Video — A method of delivering quality video in a format that 
consists of the luminance signal and two separate chrominance signals and are 
defined as YPbPr for analog component and YCbCr for digital component. 
Component video is available on DVD players.
Composite Video — A video signal that combines the luma (brightness), chroma 
(color), burst (color reference), and sync (horizontal and vertical synchronizing 
signals) into a signal waveform carried on a single wire pair. There are three kind of 
formats, namely, NTSC, PAL and SECAM.
Compressed Resolution — If the input images are of higher resolution than the 
native resolution of the projector, the resulting image will be scaled to fit the 
native resolution of the projector. The nature of compression in a digital device 
means that some image content is lost.
Contrast Ratio — Range of light and dark values in a picture, or the ratio between 
their maximum and minimum values. There are two methods used by the 
projection industry to measure the ratio:
1Full  On/Off — measures the ratio of the light output of an all white image (full 
on) and the light output of an all black (full off) image. 
2ANSI — measures a pattern of 16 alternating black and white rectangles. The 
average light output from the white rectangles is divided by the average light 
output of the black rectangles to determine the 
ANSI contrast ratio. 
Full On/Off contrast is always a larger number than ANSI contrast for the same 
projector. 
						

							Glossary77
dB — decibel — A unit used to express relative difference in power or intensity, 
usually between two acoustic or electric signals, equal to ten times the common 
logarithm of the ratio of the two levels. 
Diagonal Screen — A method of measuring the size of a screen or a projected 
image. It measures from one corner to the opposite corner. A 9FT high, 12FT 
wide, screen has a diagonal of 15FT. This document assumes that the diagonal 
dimensions are for the traditional 4:3 ratio of a computer image as per the example 
above. 
DHCP — Dynamic Host Configuration Protocol — A network protocol that 
enables a server to automatically assign a TCP/IP address to a device.
DLP
® — Digital Light Processing™ — Reflective display technology developed by 
Texas Instruments, using small manipulated mirrors. Light passes through a color 
filter is sent to the DLP mirrors which arrange the RGB colors into a picture 
projected onto screen, also known as DMD.
DMD — Digital Micro-Mirror Device — Each DMD consists of thousands of 
tilting, microscopic aluminum alloy mirrors mounted on a hidden yoke.
DNS — Domain Name System — An internet service that translates domain 
names into IP addresses.
Focal Length — The distance from the surface of a lens to its focal point.
Frequency — It is the rate of repetition in cycles per seconds of electrical signals. 
Measured in Hz (Hertz).
HDCP — High-Bandwidth Digital-Content Protection — A specification 
developed by Intel™ Corporation to protect digital entertainment across digital 
interface, such as DVI, HDMI.
HDMI — High-Definition Multimedia Interface — HDMI carries both 
uncompressed high definition video along with digital audio and device control 
data in a single connector.
Hz (Hertz) — Unit of frequency.
Keystone Correction — Device that will correct an image of the distortion 
(usually a wide-top narrow-bottom effect) of a projected image caused by 
improper projector to screen angle.
Maximum Distance — The distance from a screen the projector can be to cast an 
image that is usable (bright enough) in a fully darkened room. 
Maximum Image Size — The largest image a projector can throw in a darkened 
room. This is usually limited by focal range of the optics. 
Minimum Distance — The closest position that a projector can focus an image 
onto a screen.

NTSC — National Television Standards Committee. North American standard for 
video and broadcasting, with a video format of 525 lines at 30 frames per second.
PAL — Phase Alternating Line. A European broadcast standard for video and 
broadcasting, with a video format of 625 lines at 25 frames per second.
Reverse Image — Feature that allows you to flip the image horizontally. When 
used in a normal forward projection environment text, graphics, etc. are 
backwards. Reverse image is used for rear projection.
RGB — Red, Green, Blue — typically used to describe a monitor that requires 
separate signals for each of the three colors.
S-Video — A video transmission standard that uses a 4-pin mini-DIN connector 
to send video information on two signal wires called luminance (brightness, Y) and 
chrominance (color, C). S-Video is also referred to as Y/C.
SECAM — A French and international broadcast standard for video and 
broadcasting, closely related to PAL but with a different method of sending color 
information.
SVGA — Super Video Graphics Array — 800 x 600 pixels count.
SXGA — Super Extended Graphics Array, — 1280 x 1024 pixels count.
UXGA — Ultra Extended Graphics Array — 1600 x 1200 pixels count.
VGA — Video Graphics Array — 640 x 480 pixels count.
 XGA — Extended Video Graphics Array — 1024 x 768 pixels count.
Zoom Lens — Lens with a variable focal length that allows operator to move the 
view in or out making the image smaller or larger. 
Zoom Lens Ratio — Is the ratio between the smallest and largest image a lens can 
projector from a fixed distance. For example, a 1.4:1 zoom lens ratio means that a 
10 foot image without zoom would be a 14 foot image with full zoom.
