INTRODUCTION  
The Knöll HD282 Introduction  
Congratulations and thank you for your choice of a superior digital image projection device. Your  
new Knöll HD282 is specifically designed for home cinema applications. The HD282 sets new  
standards for high-definition digital perfection, featuring true High Definition 1280x720 resolution  
using the latest DLP™ technology and new DCDi video processing from Faroudja™. Calibrated  
to D65 color mastering standards, the HD282 reproduces colors and details the way the director  
intended. Whether you are watching movies or High Definition broadcasts or playing the latest  
video game, you will enjoy breathtaking image quality.  
Usage Guidelines  
1. Do not look directly into the projection lens when the lamp is turned on. The bright light may  
harm your eyes.  
2. Do not block the grills on the projector. Restricting the airflow can cause it to overheat and turn  
off. If this happens, you must wait a minute before turning it back on.  
3. Handle the projector as you would any product with glass components. Be especially careful  
not to drop it.  
4. Avoid leaving the projector in direct sunlight or extreme cold for extended periods of time. If  
this happens, allow it to reach room temperature before use.  
5. Transport the  
projector in a  
vendor-approved  
hard or soft case.  
6. Do not subject  
projector to  
prolonged  
exposure to  
smoke. Smoke  
may cause  
damage to the  
projector.

SETTING UP THE PROJECTOR  
There are a number of factors to consider when determining where to set up the projector,  
including the size and shape of your screen, the location of your power outlets, and the distance  
between the projector and the rest of your equipment. But here are some general guidelines.  
NOTE: To ensure adequate cable access, do not place the  
projector within 6 inches (.15m) of a wall or other object.  
Position the projector on a flat surface at a right angle to the screen.  
The projector should be within 10 feet (3 m) of your power source and within 6 feet (1.8 m) of  
your video source(s), unless good quality extension cables are to be used.  
When installing the projector on the ceiling, refer to the installation guide that comes with the  
Ceiling Mount Kit for more information. Knöll recommends use of an authorized Knöll CM25  
ceiling mount. The addition of a CM20+6 extension bar lowers the projector 6” per bar as  
required. The ceiling mount kit may be sold separately.  
Position the projector the desired distance from the screen.  
NOTE: The projector must be at least 5.6 feet (1.7 m) from the projection screen.  
The distance from the lens of the projector to the screen, the zoom setting, and the video format  
determine the size of the  
projected image.  
Projector Positioning  
The projected image becomes  
larger as the distance between  
the unit and screen increases.  
The HD282 manual zoom allows  
the distance from the screen to  
be within a minimum and  
maximum range. See the chart  
on the next page for details. The  
example on the right shows a  
very large image 10’ high by  
17.8’ wide. Note the bottom of  
the image starts about 1.6’ above  
the lens center with a horizontally  
or flat mounted projector.

Rear Connector Panel  
The projector provides eight discreet video connectors:  
two component RCA, two S-video, one composite RCA, one M1-DA (HD, DVI, and computer),  
one VESA (HD, HD component, and computer) and one component D5.  
It also has a mini-jack input for a Knöll, Niles or Xantech-compatible IR repeater and an RS-232 connector  
for serial control. The Command Line Interface (CLI) specifications and commands are listed in the  
Appendix.  
Two 3.5 mm mini-  
jack triggers  
provide 12-volt  
current. Trigger 1  
provides a con-  
stant output while  
the projector is on.  
If you connect your  
projection screen  
to Trigger 1, when  
you turn on the  
projector the  
screen will move  
down; when you  
turn the projector  
off, the screen will  
return to the  
storage position.  
Trigger 2 provides  
a 4:3 aspect  
trigger. When you  
select 4:3 in the  
Aspect Ratio menu  
or from the Resize  
button on the  
remote, a 12v  
signal will be sent  
after a five second  
delay. Use this  
trigger for screens  
with 4:3 aspect  
curtains. When  
you switch back to  
16:9 format, the  
curtains open to  
reveal the entire screen.

Video Connections  
1. Place the projector on a flat surface or using a ceiling mount kit, on the ceiling.  
If you want to project from behind a rear projection screen, set up the projector behind  
your screen.  
2. Position the projector the desired distance from the screen.  
The distance from the lens of the projector to the screen and the zoom setting determine  
the size of the projected image. See the table on page 7 for maximum and minimum  
distances for a given screen size.  
3. Make sure the projector and source equipment and/or computer are turned off.  
Make sure the projector is unplugged and your equipment is turned off.  
WARNING: Do not place the projector on a tablecloth or other soft covering that may block the vents.  
Do not use a non-Knöll ceiling mount. In the unlikely event of the bulb rupturing, thoroughly clean the  
area in front of the projector and discard any edible items placed in that area.  
Connecting a Video Device  
You can connect VCRs, DVD players, camcorders, digital cameras, video games, HDTV receivers, and TV  
tuners to the projector. (You cannot directly connect the coaxial cable that enters your house from a cable or  
satellite company; the signal must pass through a tuner first. Examples of tuners are digital cable boxes,  
VCRs, digital video recorders, and satellite TV boxes. Basically, any device that can change channels is  
considered a tuner.) Audio must be provided by your own speakers, as the projector has no separate audio  
controls. If  
there is more  
than one  
output, select  
the highest  
quality one.  
DVI  
Component  
video and  
RGB (M1,  
HD15) have  
the best  
quality,  
followed by S-  
video, and  
then  
composite  
video.

The menus are grouped by usage:  
The Picture menu provides image adjustments.  
The Settings menu provides set-up type adjustments that are not changed often.  
The About menu provides a read-  
only display of information about  
the projector and source.  
Certain menu items may be hidden  
until a particular source is  
connected. For example, Tint is  
only available for NTSC video  
sources and will be hidden when  
other sources are active. Other  
menu items may be grayed out when they are not available. For example, Brightness is grayed out until an  
image is active.  
Picture menu  
To adjust the following five settings, highlight the setting,  
press Select, use the up and down arrows to adjust the  
values, then press select to confirm the changes.  
Keystone: adjusts the image vertically and makes a  
squarer image. You can also adjust keystone from the  
keypad.  
Contrast: controls the degree of difference  
between the lightest and darkest parts of the picture and changes the amount of black and white in the  
image.  
Brightness: changes the intensity of the image. You can also adjust brightness from the keypad.  
Color: (video sources only) adjusts a video image from black and white to fully saturated color.  
Tint: (NTSC video sources only) adjusts the red-green color balance in the image.  
Aspect Ratio: Aspect ratio is the ratio of the image width to  
image height. TV screens are usually 1.33:1, also known as  
4:3. HDTV and most DVDs are 1.78:1, or 16:9. You can  
choose Native, 4:3, 16:9, Letterbox, or Natural Wide. The  
default is 16:9. The goal is to show the most detail on the  
screen while preserving the ratio of width to height. The native  
resolution of the projector is 1280x720. Use Native, 4:3 or  
Natural Wide for 4:3 input sources; use Native, 16:9 or  
Letterbox for 16:9 input. Pressing the Resize button on the  
remote cycles through these options.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
19  
Native: this mode bypasses the internal scaler, displaying the image with no resizing.  
Since the native resolution is 1280x720 and 4x3 video images are approximately  
640x480, 4x3 images will always be smaller than the display and will be centered in the  
display. Computer images 1024x768 or smaller will also be centered in the display. If a  
16x9 video source or a 1280x1024 or larger computer source is viewed, it will display up  
to 1280 pixels and 720 lines from the center of the input.  
16:9: the default is 16:9, which preserves the 16:9 aspect ratio and is designed to be  
used with content that is Enhanced for Widescreen TVs.  
4:3: resizes the image from its original version to fit a standard 4:3 aspect ratio screen. If  
you have a 4:3 source on a 16:9 screen, the image is placed in a 16:9 space, so black  
bars appear at the sides of the image.  
Letterbox: preserves the 16:9 aspect ratio. If you have a 16:9 source and screen, the  
image fills the screen. If your source is letterboxed, the image expanded to fill the  
screen.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
20  
Natural Wide: this mode stretches a 4:3 image to fill the entire 16:9 screen. The center  
two-thirds of the image is unchanged; the edges of the image are stretched.  
Presets: This allows you to customize settings and save the settings to be restored later. To restore the  
factory default settings, choose Factory Reset in the Settings>Service menu.  
To set a preset for the current source, adjust the image, select Save Settings in the Presets menu, then  
choose Save User 1, 2, or 3. You can recall these settings in the future by selecting the appropriate user  
presets.

Advanced settings  
TrueLife: This option refers to Faroudja’s  
TrueLife processing of the image. All standard  
definition interlaced video signals (composite,  
S-video and component) are routed through  
this processor. Extended and High Definition  
progressive component sources are not  
routed though this processor by default. You  
can turn TrueLife on to route these signals  
through the processor and then adjust the  
following 2 options:  
Chroma Detail: This adjusts the color  
sharpness.  
Luma Detail: This adjusts the sharpness.  
Noise Reduction: adjusts signal noise  
reduction. Choose Off to have no noise  
reduction, choose Auto to have the software  
determine the amount of noise reduction, or  
choose Manual and adjust the Level.  
Skintone Bypass prevents the noise reduction processing from being applied to skin tones. Images of  
people often look better with less processing. Available when Auto or Manual are selected.  
CCS: (Cross Color Suppression) processes the signal to remove any color information from the luma portion  
of the signal. It is On for all composite signals, Off for all component signals, and can be turned on or off for  
all S-video signals.  
NTSC 2:2 Pulldown: Turn this feature on to correctly display NTSC signals created from 30-frames/second-  
source material (instead of the film standard 24 frames/ second).  
2:2/3:2 Off: Turn this feature on to turn off film mode detection. Some video material (especially film  
animation) is difficult to distinguish from film.  
Color Space: This option applies to computer and HDTV  
sources (it won’t appear in the menu for video sources). It  
allows you to select a color space that has been specifically  
tuned for the video input. When Auto is selected, the  
projector automatically determines the standard. To choose  
a different setting, turn off Auto, then choose RGB for  
computer sources, choose REC709 for component 1080i or  
720p sources, or choose REC601 for component 480p or  
576p sources.  
Color Temperature: changes the intensity of the colors. Select  
a listed value.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
22  
Color Control: allows you to individually adjust the gain  
(relative warmth of the color) and the offset (the amount of black  
in the color) of the red, green, and blue colors.  
Gamma: Gamma tables contain preset intensity configurations  
optimized for the input source. You can select a gamma table  
that has been specifically tuned for either film, video, Bright  
Room, or PC input. (Film input is material originally captured on  
a film camera, like a movie; video input is material originally  
captured on a video camera, like a TV show or sporting event.)  
NOTE: Your viewing preferences may vary. Cycle through  
the gamma options and pick the one you like the best.  
Video Standard: When it is set to Auto, the projector  
attempts to pick the video standard automatically based on  
the input signal it receives. (The video standard options may  
vary depending on your region of the world.) If the projector is  
unable to detect the correct standard, the colors may not look  
right or the image may appear “torn.” If this happens,  
manually select a video standard by selecting NTSC, PAL, or  
SECAM from the Video Standard menu.  
Overscan: (video sources only) removes noise around the video image.  
The following options are for computer or HDTV sources only  
Phase: adjusts the phase of the video signal’s digital conversion.  
Tracking: adjusts the frequency of the video signal’s digital conversion.  
Horizontal/Vertical Position: adjusts the position of the source.  
Settings menu  
Sources: allows you to assign a particular  
input to a specific source key on the remote  
and enables or disables Autosource. When  
Autosource is not checked, the projector  
defaults to the last-used source. If no source is  
found, a blank screen displays. When  
Autosource is checked, the projector checks  
the last-used source first at power up. If no signal is  
present, the projector checks the sources in order  
until a source is found or until power down.

23  
The Source Enable feature is used to eliminate  
certain sources from this search, which will speed the  
search. By default, the check boxes for all sources  
are checked. Uncheck a source’s box to eliminate it  
from the search.  
System  
All options in this menu toggle between on and off.  
Rear: reverses the image so you can project from  
behind a translucent screen.  
Ceiling: turns the image upside down for ceiling-  
mounted projection.  
NOTE: It is recommended that all final image adjustments in Ceiling mode are made once the unit has fully  
warmed up (approximately 20 minutes).  
Auto Power: When Auto Power is checked, the projector automatically goes into the startup state after the  
projector receives power. This allows control of ceiling mounted projectors with a wall power switch.  
Display Messages: displays status messages (such as “Searching”) in the lower-left corner of the screen.  
High Power: Turn this on to increase the light output of the lamp. This also shortens lamp life and increases  
fan noise.  
Translucent OSD: makes the menus translucent. This prevents the image from being completely covered  
by the menus while you are making image adjustments.  
Chime: turn this on to hear a sound when the Power button is pressed.  
Power Save: when On, the lamp is automatically turned off after no signals are detected for 20 minutes.  
After 10 additional minutes with no signal, the projector powers down. If an active signal is received before  
the projector powers down, the image will be displayed.  
Startup Logo: allows you to display a blank Black, White, or Blue screen  
instead of the default screen at startup and when no source is detected.

Factory Reset: restores all settings (except Lamp Hours, Ceiling, and Rear) to their default after displaying  
a confirmation dialog box.

patterns, use the up/down arrows on the remote or keypad.  
Service Code: only used by authorized service personnel.  
Maintenance  
Cleaning the lens  
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.  
Avoid using an excessive amount of cleaner, and  
don’t apply the cleaner directly to the lens.  
Abrasive cleaners, solvents or other harsh  
chemicals might scratch the lens.  
Lightly wipe the cleaning cloth over the lens in a  
circular motion. If you don’t intend to use the  
projector immediately, replace the lens cap.

Replacing the projection lamp  
The lamp hour timer in the About menu counts the number of hours the lamp has been in use. After 1980  
hours, the message “Change lamp” briefly appears on the screen at each startup. To maintain optimal video  
performance, we recommend changing the lamp after 2000 hours, depending on usage. You can order new  
lamp modules from your dealer.  
.
1. Turn off the projector and unplug the power cable.  
2. Wait 60 minutes to allow the projector to cool thoroughly.  
3. Turn the projector upside down and remove the lamp door by  
removing the two screws and sliding the lamp door tabs out of  
the three tab bays.  
CAUTION: Never operate the projector with the lamp door  
removed. This disrupts the airflow and causes the projector to  
overheat.  
4. Loosen the captive screw on the lamp module.  
WARNINGS:  
To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp.  
Do not drop the lamp module. The glass may shatter and cause injury.  
Do not touch the glass lamp screen. Fingerprints can obscure projection sharpness.  
Be extremely careful when removing the lamp module. In the unlikely event that the lamp ruptures, small  
glass fragments may be generated. The lamp module is designed to contain most of these fragments, but  
use caution when removing it.  
5. Carefully remove the lamp module by grasping and lifting the metal bail wire. Dispose of the lamp in an  
environmentally proper manner.  
6. Install the new lamp module. Make sure that it is properly seated.

8. Replace the lamp door by sliding the tabs into the tab bays and tightening the two screws.  
9. Plug in the power cable, then press the Power button to turn the projector back on.  
10. Reset the lamp hour timer.  
Resetting the lamp timer  
To reset the lamp age, simultaneously holding down the two Brightness buttons on the projector’s keypad  
for 10 seconds.  
Using the security lock

RS232 Terminal Specifications and Commands  
To control the projector from an LCD control panel, connect an RS-232 cable to the serial control  
connec8tor on the projector and set your computer’s serial port settings to match this communication  
configuration:  
Command format  
All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. The request  
can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4 ASCII digits).  
A read request format: (AAA?) where  
(
starts the command  
AAA denotes the command  
?
)
denotes the read request  
ends the command  
A read command returns  
the range and the current  
setting, for example:  
A write request example: (AAA####) where  
(
starts the command  
AAA denotes the command  
#### denotes the value to be written  
(leading zeros not necessary)  
)
ends the command  
Some commands have ranges, while others are absolute. If a number greater than the maximum range is  
received, it is automatically set to the maximum number for that function. If a command is received that is  
not understood, a “?” is  
returned. With absolute  
settings, “0” is off, 1-9999  
is on.  
The one exception is the  
Power command, where 0  
is off and 1 is on.
