Important Operating Considerations for Safety  
Place the projector in a horizontal position no greater than 15 degrees off axis.  
Locate the projector in a well-ventilated area without any obstructions to intake or  
exhaust vents.  
Do not place the projector on a tablecloth or other soft covering that may block the vents.  
Locate the projector at least 4' (1.2 m) away from any heating or cooling vents.  
Use only Knoll-approved ceiling mounts.  
Use only the power cord provided. A surge-protected power strip is recommended.  
Refer to this manual for proper startup and shutdown procedures.  
In the unlikely event of the lamp rupturing, discard any edible items placed in the  
surrounding area and thoroughly clean the area along all sides of the projector.  
Wash hands after cleaning the area and handling the ruptured lamp. This product has a  
lamp, which contains a very small amount of mercury. Dispose of it as required by local,  
state or federal ordinances and regulations. For more information see www.eiae.org.  
Follow these instructions to help ensure image quality and lamp life over the life of the projector.  
Failure to follow these instructions may affect the warranty. For complete details of the warranty,  
see the Warranty section at the end of this User's Guide.

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 (0.15 m) 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. Knoll recommends use of the mount shipped with the  
projector or the deluxe swivel Knoll CM26 ceiling mount. The addition of a CM20+6 extension bar  
lowers the projector 6” per bar as required. The CM25EX is an adjustable extender that can lower  
the projector 6.75” to 11” (17-28 cm). The ceiling mount kit may be sold separately.  
Position the projector the desired distance from the 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 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 below defines the screen height,  
width, diagonal, offset, etc. Note the bottom of the image starts about below the lens center with a  
horizontally or flat mounted projector.

Video Connectors  
Component RCA  
S-Video  
12-volt DC output  
HDMI  
M1/DA/DVI  
Composite RCA  
RS-232 (not on HD108)  
The first step for connecting video is determining what type of output connectors your video  
Component RCA device has. If there is more than one output, select the one with the highest  
quality. The best quality ranking, with 1 being the highest, is:  
1. M1-DA/DVI or HDMI (both are digital inputs)  
2. Component /SCART RGB video (RCAs)  
3. S-video  
4. Composite Video (RCA)  
If your device has a VGA connector, you can use the M1-DA/DVI connector for a high-quality  
image. Many PC game systems have VGA connectors.  
Connecting a video device  
You can connect video devices such as VCRs, DVD players, camcorders, digital cameras, video  
game consoles, HDTV receivers, and TV tuners to the projector. Connect the audio from your  
video device to your stereo system to get sound. You can connect the projector to most video  
devices that can output video.  
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.  
A composite video cable is provided with your projector so you can quickly and easily connect a  
video source to the projector and see the amazing image that is displayed. Once you have  
determined a more permanent location for your projector, we recommend purchasing higher  
quality cables in the proper length to get the best image from your particular video equipment.  
10  
Composite (RCA) video connection  
Plug the composite video cable’s yellow connector into the video-out connector on the video  
device. Plug the other yellow connector into the yellow Composite connector on the projector.  
S-video connection  
If your video device uses a round, four-prong S-video connector, plug the S-video cable into the  
S-video connector on your video device and into the S-video connector on the projector.  
Component (RCA) connection  
If your device uses component connectors, plug a component video cable with red, green, and  
blue RCA connectors into the source device’s component connectors and the Component  
connectors on the projector.  
SCART RGB connection  
SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a  
French-originated standard and connector for connecting audio and video equipment to display  
devices. The video signal is separated into its primary components for brighter, more accurate  
colors and sharper detail. You must enable this connector in the Source Enable menu to use it,  
see page 20. You will also need a SCART to 4-RCA adapter to connect to your SCART device.  
Digital connections  
The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) connectors are digital and yield  
the highest quality image. It is common for these signals to be encrypted with HDCP (high-band  
width digital-content protection). Your new projector ships standard with decryption codes so you  
can enjoy these high quality, all digital images.  
This projector uses the M1-DA connector, which has the following advantages:  
• allows connection to a digital DVI source  
• allows connection to a component source  
• allows connection to an analog computer source  
• carries a USB control signal, which allows you to easily update your projector’s software as  
enhancements become available.  
• has output pins that can power accessories.  
The HD290 is a HDTV (High Definition Television) monitor, meaning it has vertical scanning lines  
of 720 progressive, 1080 interlaced or higher. The HD108 and HD178 are EDTV (Enhanced  
Definition Television) monitors, meaning they have vertical scanning lines of 480 progressive or  
higher. EDTV monitors can display HD content, but the resolution is less than that of HDTV.  
DVI connection  
If your video device uses a DVI connector, plug the DVI end of an M1-DA cable into the video-out  
connector on the video device. This connector may be labeled “To Monitor” on the video device.  
Plug the M1-DA end of the cable into the M1-DA/DVI connector on the projector.  
HDMI connection  
HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI provides an interface  
between sources, such as set-top boxes, DVD players, and receivers and your projector. Plug an  
HDMI cable into the video-out connector on the video device and into the HDMI connector on  
the projector.  
Note that the projector has no audio capabilities, so audio signals transferred through HDMI  
will not be audible.  
11  
Computer connections  
You can connect a computer’s VGA connector to the M1-DA/DVI input on the projector using an  
M1-A cable.  
RS-232 connections (HD178 and HD290 only)  
You can control the projector from an LCD control panel or computer by connecting an RS-232  
cable to the projector’s Serial control connector.

Color Control  
Color Control: allows you to individually adjust the  
gain and offset of the red, green, and blue colors.  
These advanced controls have the same effect as  
contrast and brightness, but each controls a single color only.  
Video Standard: when it is set to Auto, the projector  
attempts to automatically pick the video standard 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

Overscan: removes noise around the edges of the video  
image. Select Zoom to remove the outer 3 percent of the  
image and scale the image back up to its original  
size. Select Crop to remove the outer 3 percent of the  
image without rescaling the image.  
Overscan  
Noise Reduction: adjusts signal noise reduction.  
Choose Enable then adjust the level. The software  
determines the differences between successive image  
frames and averages the changes out to reduce the noise.  
Noise reduction  
Settings menu  
Sources: allows programming of source buttons,  
enables autosource, and enables the SCART RGB  
source. When Autosource is selected, the Source  
Enable feature indicates which sources the projector  
attempts to lock onto. You can use the Source Enable  
feature to eliminate certain sources from this  
search, which will speed the search. By default,  
the check boxes for all sources are checked except  
SCART RGB. Uncheck a source box to eliminate  
it from the search.  
Settings  
20  
When Autosource is not checked, the projector defaults to Component initially, then defaults to  
whatever the last active source was when the projector was powered down. To display another  
source, you must manually select one by pressing the Source button on the remote or keypad.  
This cycles through all the sources that are selected in the Source Enable menu.  
The Source 1, 2, and 3 menus in the Sources menu allow  
you to assign a source to the Source 1, 2, and 3 buttons  
on the remote. The Source 4 menu selection would  
apply to the Custom key if that option is chosen in the  
Custom key menu, see page 21.  
Sources  
Source Enable  
To use the SCART RGB source, you must first select  
it in the Source Enable menu (the projector cannot  
automatically detect this source). Enabling  
SCART will disable Component and Composite  
sources.  
System>Rear: reverses the image so you  
can project from behind a translucent screen.  
Ceiling: turns the image upside down for  
ceiling-mounted projection. Auto Ceiling:  
uses an internal sensor to automatically turn  
on ceiling mount mode if the projector  
System menu  
is inverted. High Power: maximizes the light  
output of the lamp. 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.  
Translucent OSD: makes the menus translucent. This prevents the image from being completely  
covered by the menus while you are making image adjustments. Sleep Timer: automatically  
turns off the projector after 4 hours. Power Save: automatically turns the lamp 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 is displayed.  
Startup Logo: allows you to display a blank screen or  
a custom captured image (HD108 only) instead of the  
default screen at startup.  
To capture a new image, display the image and select  
Capture New. A message appears. Select Captured in  
the Startup Logo menu to display your new image.  
Note that this feature will not work on interlaced signals.  
Startup logo  
Blank Screen  
Blank Screen: determines what color is displayed when  
you select Blank Screen in the Startup Logo menu  
and when no source is displayed.  
Language: allows you to select a language for the  
onscreen display.

Custom key: allows you to assign a different function  
to the Custom key on the remote, allowing you to  
quickly and easily use the effect. Highlight an

Source Info: the default effect. It opens a window with projector and source information.  
Service Info: opens the Service info window.  
Source 4: selects source 4 (by default, Source 4 is the Composite input). This gives you four  
direct source options on the remote. See page 20.  
Service: To use these features, highlight them and press Select.  
Factory Reset: restores all settings to their default.  
Service menu  
Reset Lamp Hours: resets the lamp hours used  
counter in the Service Info menu to zero. Do this  
only after changing the lamp.  
Test Pattern: displays a test pattern. To display  
test patterns, first you must assign Blank  
Screen to the Custom key (page 21), then click the  
Test pattern check box in the Service menu to  
turn the option on, exit the menus, then press the  
Custom button on the remote. To select the  
patterns, use the up/down arrows on the remote  
or keypad. To exit the test patterns, press  
the Custom button.  
Service info  
Blue Only: turns off the Red and Green  
portions of the input, allowing you to properly  
adjust the color balance with a SMPTE color  
bar pattern.

Some graphic cards cannot recognize the  
projector’s EDID. Uncheck this box if you  
have trouble using HDMI or DVI sources.

been in use. Twenty hours before the lamp life  
expires, a message appears on the screen  
at startup indicating that you should change the  
lamp. The LED on top of the projector also blinks  
red twice to indicate that the lamp should be  
changed. Use only a replacement lamp with the  
same type and rating as the original lamp.

RS232 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  
denotes the command  
denotes the read request  
ends the command  
AAA  
?
)
A read command returns the range and the current setting, for example:  
Function  
Command  
Response  
Brightness  
Lamp hours  
(BRT?)  
(LMP?)  
(0-22,10)  
0-9999,421)  
A write request example: (AAA####) where  
(
starts the command  
denotes the command  
AAA  
#### denotes the value to be written (leading in 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, 1-999 is on.  
The one exception is the Power command, where 0 is off and 1 is on.
