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 HD272 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

18
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
Naural 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.

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.

Blank Screen: determines what color displays when you press
the Blank button on the remote or when no source is active.
Language: allows you to select a language for the onscreen
display of menus and messages.
Service Menu
Use these features, highlight them and press Select.
Factory Reset: restores all settings (except Lamp Hours, Ceiling, and Rear) to their default after displaying
a confirmation dialog box.
Test Pattern: displays a test pattern when the Blank button on the remote is pressed. To select the
patterns, use the up/down arrows on the remote or keypad.
Service Code: only used by authorized service personnel.

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 air flow 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, making sure that it is properly seated.

RS232 Terminal Specifications and Commands
To control the projector from an LCD control panel, connect an RS-232 cable to the serial control
connector 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.
