users or installers should always consult their dealer when deciding on screen
type. The following guidelines explain the differences between screen types.
Front Screen Installations
There are two basic screen types: flat and curved. The choice between a flat
screen or a curved screen is dependent on audience viewing angle and screen
gain. There is always a trade-off between viewing angle and gain. Viewing
angles for both screen types are illustrated in Figures 2-1 and 2-2 (plan views).
Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all directions so the audience can see the display
from various angles. Because of the lower gain, flat screens are more effective
when ambient lighting is reduced.
DLV 1280
User's Manual
2-3
INSTALLATION & SETUP
Figure 2-1. Audience Coverage with Flat Screen
Figure 2-2. Audience Coverage with Curved Screen
Curved screens have gains larger than 1 (due in part to the screen material) and
viewing angles much less than 180°. Most curved screens have different
horizontal and vertical viewing angles. Incident light does not reflect equally in
all directions. The reflected light concentrates in a conical volume or "viewing
cone". Audiences within the viewing cone see a brighter image than that from an
equal area on a flat screen. Audiences outside the viewing cone see a dimmer
image.
NOTE: While DLV 1280 lenses are designed primarily for use with flat screens,
the depth-of-field range for these lenses allows focusing on curved screens as
well. Focus remains sharp, however there may be significant pincushion
distortion, primarily at the top of the screen..
Rear Screen Installations
There are two basic types of rear screens: diffused and optical. A diffused screen
has a surface which spreads the light striking it. Purely diffused screens have a
gain of less than 1. The main advantage of the diffused screen is its wide viewing
angle, similar to that of a flat screen for front screen projection. Optical screens
take light from the projector and redirect it to increase the light intensity at the
front of the screen. This reduces it in other areas. A viewing cone, similar to that
of a curved front screen installation, is created.
2-4
DLV 1280
To summarize, optical screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone. Diffused screens are best suited
when a wide viewing angle is required but there is low ambient room lighting.

Note: Stated screen sizes refer to the diagonal size of a 5:4 screen.
Screen Aspect Ratio
Choose a screen
'
aspect ratio
which is most appropriate for your application.
Aspect ratio describes the proportion of the screen and is expressed as a ratio of
width to height, such as “4:3” or “5:4”. Ideally, to exactly fill a screen with an
image, the aspect ratio of the screen should correspond to the aspect ratio of the
image, which depends
on the source in use.
For example, standard
video from a VCR has
a 4:3 aspect ratio,
whereas a high
resolution SXGA
signal (1280 x 1024)
has a 5:4 aspect ratio.
Figure 2-3. Aspect Ratios
See Figure 2-3.
NOTE: With a few exceptions, sources with
than 1280 x 1024 resolution
less
have a 4:3 aspect ratio. The correct aspect ratio for 1280 x 1024 sources is 5:4.
Using a 5:4 Screen
If you use a mix of sources—i.e., those with the rectangular 4:3 aspect ratio as
well as those with the slightly more square 5:4 aspect ratio—a 5:4 screen will
likely provide the most flexibility. With a 5:4 screen, a 5:4 source image
naturally fills the screen at an established
throw distance. Filling the same screen
with a 4:3 source image requires only a
simple software adjustment to slightly
expand the image to the top and bottom
edges of the screen (Figure 2-4). See 3.6,
Adjusting the Image.
Figure 2-4. Adjusting a 4:3 Image
Using a 4:3 Screen
With a 4:3 screen, 4:3 sources will naturally fill the screen at an established
throw distance. Filling the same screen with a 5:4 source image (one from a 1280
x 1024 source) requires a reduction in this throw distance so that the “too tall”
5:4 image no longer spills over the top or bottom of the screen. Once set up in
this manner, all images will then have side borders (Figure 2-5), with most 4:3
images changing aspect ratio as well.
NOTE: For existing installations having multiple 4:3 screens, you can use
Electrohome’s EX-1200 or EX-2000 Display Wall controller to fill each screen.

Room Lightin
While it is always preferable to operate the projector in an ideal projection room
'
environment, the high brightness output of DLV 1280 is well suited for locations
where ambient lighting may be less than optimum for projection. For temporary
installations where the room may not be designed for projection, there are many
simple things which can be done to avoid problems caused by unwanted light.
Visiting a movie theater can give you an idea of what makes a good projection
environment. Walls, floors and furnishings are dark and matte finished. A
projection room should not have reflective white ceilings or non-directional
lighting such as fluorescent lights. The white ceiling spreads light, making the
room appear brighter. Keep lighting and reflections to a minimum.
If it is not possible to eliminate fluorescent lights, consider using parabolic
reflectors ("egg crates") to direct light down to the floor. Incandescent spot
lighting is a better way to obtain illumination. Light dimmers or rheostats allow
you to further control the lighting.
Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have
windows, make sure that window coverings are opaque and overlapping — some
window coverings are designed to provide up to 100 percent blockage of outside
light. Ideally, the material should have a matte finish.
2-6
DLV 1280
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2-6 shows an
installation where poor screen placement allows too much unwanted light to
enter the screen. In Figure 2-7, the screen and the projector are positioned to
minimize the effect of unwanted light.
Figure 2-6. Poor Screen Placement
User's Manual
Other Considerations
INSTALLATION & SETUP
Figure 2-7. Better Screen Placement
Even with all lighting removed it is still possible that room reflections within the
room can degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to
the screen. Again, reflective surfaces should be kept to a minimum.
Here are some other considerations and tips which can help you improve your
'
installation:
• Ventilation is an important factor when preparing a projection room. The
ambient temperature should be kept constant and below 35°C (95°F). Keep
the projector away from heating and/or air conditioning vents. Changes in
temperature can cause drifts in the projector circuitry which may affect
performance.
• Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide
projectors, speakers, power amplifiers, elevators, etc.
• For rear screen applications, less space is required if a mirror is used to fold
the optical path.
• Choose the right screen size for the application:
◊ As screen size increases, magnification increases which reduces
brightness. Select a screen size which is appropriate for the venue,
but not larger than that required.
◊ Installing a large screen in a small room is similar to watching
television close up; too large a screen can overpower a room. A good
rule of thumb is to be no closer than 1.5 times the width of the
screen.
◊ Larger screens require greater attention to lighting conditions.
• When laying out the projection room, consider positioning the projector and
screen in a manner which will achieve maximum audience coverage and
space efficiency. For example, placing the screen along the larger wall in a
rectangular room will reduce audience coverage. Figure 2-8 shows two
examples of how audience coverage is maximized.
• Keep in mind that for good display of text information, the image size must
allow the audience to distinguish all text clearly. In general, the eye can
DLV 1280
User's Manual

INSTALLATION & SETUP
recognize a letter if eye-to-text distance is less than 150 times the height of
the letter. Text will normally become illegible at a greater distance despite
the sharpest and clearest of images.
Figure 2-8. Screen Locations for Maximum Audience Coverage
2.3 Projector
Position and

Throw Distance
As mentioned, installation type, screen type, and lighting all affect where the
projector is positioned. In addition, both throw distance (the distance between
the projector and screen) and horizontal/vertical position must be determined for
every new installation. Both depend on screen size and projector lens type. Make
sure that the room can accommodate the required position of the projector for the
chosen screen size.
Throw distance is the distance between the projector's front feet and the screen
'
(measured perpendicular to the screen and projector, not necessarily parallel to
floor). As the distance between the projector and the screen increases, image size
also increases.
Throw distance is roughly equal to the horizontal width of the screen multiplied
by the type of lens you are using. For example, if using a 1.2:1 lens, throw
the horizontal screen width. Once you
distance should be roughly equal to 1.2
x
know your horizontal screen size, you can determine how far away the projector
should be:
Table 2-2. Throw Distance Guide
Lens Type Approx. Throw Distance
2:1 - 3:1 2x to 3x horizontal screen width
1.2:1 (no zoom) 1.2x horizontal screen width
1.5:1 - 3:1 1.5x to 3x horizontal screen width
3:1 - 7:1 3x to 7x horizontal screen width
2-8
DLV 1280
NOTES: 1) Throw distance is measured perpendicular to the screen and
projector, not necessarily parallel to the floor. 2) It is good practice to simulate
the setup with the projector fully warmed-up to determine the actual throw
distance required.
User's Manual
INSTALLATION & SETUP
Horizontal Position
Vertical Position
Correct horizontal position of the projector can ensure that the image is
'
positioned properly on the screen. With any lens installed, the image can be
manually offset left or right by a distance of up to 25 pixels (Figure 2-9). Turn
the horizontal offset adjustment knob on the top edge of the projector as desired.
Figure 2-9. Horizontal Offsets, All DLV 1280 Lenses
The vertical position of the projector in relation to the screen also depends on the
'
size of the screen and the lens type. Correct vertical position ensures that the
image will be rectangular in shape rather than keystoned (having non-parallel
sides). Depending on the type of lens you are using, the image can also be offset
up or down by turning the vertical offset adjustment knob on the top edge of the
projector.
The number of pixels by which you can raise or lower an image are listed in
Table 2-3. In addition, refer to Figure 2-10 to see how these pixel offsets affect
the placement of your image. If your projector is inverted, such as with a ceiling
-mounted projector, turn the illustration upside-down.
Table 2-3. Vertical Offset Ranges, in Pixels
Lens Type Vertical Offset (in Pixels)
2:1 - 3:1 zoom (standard) -25 to +366

3:1 - 7:1 zoom (opt.) -25 to +512 pixels
fixed @ 0,±25 pixels
-25 to +512 pixels
NOTE: If you cannot raise or lower the image enough, or if the image becomes
keystoned or exhibits uneven brightness, the projector is probably too high or
low in relation to the screen.

2.6 Operating
Orientation
DLV 1280 is set up at the factory for use in a front screen, floor mount
orientation. If the installation is ceiling mount or rear screen, your initial images
will likely be displayed upside down and/or reversed. To correct, you must
change the image orientation from within the Preferences menu. You may prefer
to do this before
physically installing the
projector, however it can
be done at any time. See
Section 3, Operation for
further information.
In the Preferences menu,

2.7 Leveling
For most installations
you will want to make
sure that the projector
is level from side-toside and that the lens
surface is parallel to
the screen. This will
ensure a rectangular
image that is level. To
make small corrections
to the projector's level, rotate each leg as necessary to raise or lower.

Pro
ector Number
Each projector can be assigned a unique 3-digit projector number (for example,
'
001). These numbers are particularly useful when you are working with multiple
linked projectors, enabling you to direct commands to a certain projector rather
than broadcast to all projectors. For complete information on how to assign
projector numbers, see 3.7, Adjusting and Checking System Parameters.

INSTALLATION & SETUP
2.10 Keypad
Protocols
At manufacture, every remote keypad is assigned a default protocol, which is
simply a collection of settings that determine how the keypad operates. Once
assigned, this protocol remains in effect until it is changed — that is, the keypad
will operate as it currently does until you change its protocol.
Protocols are most useful for multiple-projector applications. For example, you
might want to change one keypad protocol if you are working with two remote
keypads and two projectors in the same room and need to control each projector
independently (Figure 2-28). When Keypad A has a different protocol than
Keypad B, each keypad communicates only with the projector having a matching
protocol. Or, if you have a network of two or more projectors connected together
via RS-232 serial ports, you may want only certain projectors to respond to a
wired keypad.
NOTE: Match the protocol on the projector to that of a keypad by setting the
desired option in the Preferences menu (use Front IR, Rear IR or Wired Keypad,
depending on which you want to change). See 3.7, Adjusting and Checking
System Parameters for further information.
A protocol for either type of remote keypad — IR or wired — can be changed
through software commands entered on the keypad. A new protocol set through
software commands remains in effect until a battery is removed (if an IR
remote), or until the keypad is unplugged from the projector (if a wired remote).
The projector will automatically detect software changes. A remote can also be
changed manually — you can "hard-wire" new jumper settings inside the keypad
so that they remain in effect permanently until you change the hard-wiring back
again. Again, to temporarily override the hard-wired protocol at any time, simply
use the shortcut software command.

Changing Keypad
Protocol
DLV 1280
User's Manual
Figure 2-28. Independent Keypads and Projectors
The IR remote keypad or the optional wired remote can be set to one of two
'
different protocols — "A" or "B". To hard-wire a protocol to "A" or "B" in
either type remote, follow Steps 1 through 6.
INSTALLATION & SETUP
Step 1
In the Preferences menu, make sure that the desired keypad option (Front IR,
Rear IR, or Wired Keypad) is set to Option 1 “A or B”. This will ensure that the
projector will continue to respond to the keypad after you change protocol.
Step 2
Unplug the keypad from the projector (applies to wired remote only).
Step 3
Unlatch and open the battery compartment on the back of the keypad as shown in
Figure 2-29. Make sure the batteries are in place (IR keypad only).
NOTE: The optional wired keypad appears as shown, but there is a cable
passing through the battery compartment cover.
Figure 2-29. Opening the Keypad (shown without batteries)
Step 4
Find the 4 jumpers located along the latching side of the battery compartment
(Figure 2-30). These jumpers set the keypad protocol and other parameters so
that the keypad functions in a certain manner.
Figure 2-30. Locating and Setting the Jumpers
DLV 1280
User's Manual
2-21
INSTALLATION & SETUP
Step 5: Set the Jumpers
Set the jumpers as shown in Figure 2-30. Take care to refer to the correct part of
the drawing — IR or wired (optional). Use tweezers or needle-nose pliers to
remove and replace each jumper as necessary.
•
J1
jumper: For either remote, set between pins 1 and 2 to set as Protocol
"A". Set between pins 2 and 3 to set as Protocol "B".
•
J2
jumper: For either remote, set between pins 2 and 3 as shown; otherwise,
the projector will not respond correctly to keypad commands.
•
J3
jumper: For the IR remote, make sure that the jumper is set between pins
2 and 3 as shown. For the wired remote, make sure that the jumper is set
between pins 1 and 2 as shown.
•
J4
jumper: For the IR remote, make sure that the jumper is set between pins
1 and 2 as shown. For the wired remote, make sure that the jumper is set
between pins 2 and 3 as shown.
Step 6
Replace battery compartment cover. Plug into projector (wired keypad only) and
test.
NOTE: Although they are similar, a wired keypad cannot be converted into an
IR remote keypad, nor vice versa.
SHORTCUT METHOD FOR CHANGING PROTOCOL:
You can also issue software protocol settings through the keypad. These settings
override the hard-wired jumper settings and remain in effect until the keypad is
either unplugged or until a battery is removed. At that point, keypad protocol
will then revert back to the hard-wired jumper settings (see above). Note that the
projector will automatically detect this return to hard-wired settings and will still
respond. To set the keypad protocol through software:
Press
Press
= Protocol "A"
= Protocol "B"
NOTE: If you set a remote keypad to a new protocol and the projector stops
responding entirely, the projector may be set to a conflicting protocol. Use the
projector's built-in keypad to access the Preferences menu. Under the relevant
keypad option, select the protocol that matches the new protocol of the remote
keypad. The projector should now respond properly.
