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.

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.

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.
