Master projector
NOTE: SW 1 Level and SW 2 Level of Switcher Control are not available on Link
Mode.
For double stacking, follow the instructions described below.
1) Stacking the Projectors
1-1. Place the projectors at the proper height for best screen to projec-
tor relationship. Make sure that all projectors have the same display
orientation.
2) Hookup
2-1. Use commercially available RGB signal cables to connect the RGB
output of the master projector to the RGB input of the slave projector
until all the projectors are connected.
2-2. Next, using a commercially available, bi-directional RS-232C cable
connect the PC CONTROL OUT terminal of the master projector to
the PC CONTROL IN terminal of the slave projector until all the
projectors are connected.
2-3. Turn all the projectors on and roughly make some optical adjust-
ments to each projector.
3) Adjusting and registering signals to be projected in Link
mode and stack application.
Signal Data Preparation
3-1. Create data for the master projector and copy data to the slave
projector.
3-1-1. Choose one projector as the master.
3-1-2. Turn the master projector on.
Slave projector
Foot
Depression
for foot
3-1-3. Display all desired input signals, make adjustment to each signal,
then save all adjustments on the master projector. (Adjustments will be
saved automatically.)
3-1-4. Turn the master projector off (standby mode).
3-1-5. Store all the adjustments on a CompactFlash card from the master
projector.
3-1-5-1. Insert a CompactFlash card into the PC Card slot.
NOTE: Be sure to insert a CompactFlash card into the PC Card slot with its
front side facing downward.
3-1-5-2. Press and hold CANCEL, then press POWER on the top panel
of the master projector. The POWER indicator will change to steady
green and the PC Card Access indicator will start flashing. After stor-
ing data on the CompactFlash card, the POWER indicator will change
to orange.
3-1-5-3. Remove the CompactFlash card from the slot of the master pro-
jector.
3-1-6. Transfer the data to the other slave projector using the CompactFlash
card so that all the projectors have the same data in memory.
3-1-6-1. Insert the CompactFlash card into the slot of the slave projector.
NOTE: Since data in the slave projector will be lost at this time, make
backup copies of them before proceeding.
3-1-6-2. Press and hold ENTER, then press MENU on the top panel of the
slave projector. The POWER indicator will change to steady green and the
PC Card Access indicator will start flashing to indicate that the data is
being copied from the CompactFlash card to the slave projector. After copy-
ing data to the slave projector, the POWER indicator will change to or-
ange.
3-1-6-3. Remove the CompactFlash card from the slave projector.
NOTE: If you select the RGB1 input on the master projector, you must
select the same input on the slave projector and the RGB2 on the master
projector and the slave projector.
NOTE: After adjusting and registering signals as mentioned above, you
must change the input to RGB on the Entry Edit Command window for
Link Mode. See "Entry List Edit" on page E-41 for changing to RGB source.
3-1-6-4. Display the desired source.
4) Display the internal crosshatch test pattern.
NOTE: Use a different single color for each projector. Example:
Turn on Green of one projector (master), then Red of the other (slave).
5) Adjusting the lens shift, zoom and focus to clearly display
all projected patterns.
5-1. Adjust the Lens Shift using the LENS SHIFT button on the projec-
tor cabinet. You can also adjust the Lens Shift by pressing and hold-
ing CTL and pressing the POSITION button on the remote control.
For Lens Shift Adjustable Range, see page E-13.
5-2. Zoom the lens in and out by using the ZOOM button on the projec-
tor cabinet or the remote control.
5-3. Adjust the lens focus by using the FOCUS button on the projector
cabinet or the remote control.
NOTE: If the physical (vertical) alignment of the projector is not correct, adjust
the height of the feet. If there is any keystone distortion, use Keystone adjust-
ment to correct and save the settings on each projector. See page E-45 for
Keystone correction.
This completes set-up and adjustments. An image is projected from the master
projector. See page E-50 for Link mode.
NOTE: Up to two units can be gravity stacked without external support. In some
cases, however, two images will not align on the screen correctly. This will
become more apparent when displaying small text and detailed graphics.
CAUTION: To prevent the projectors from falling, install them in a place and
fasten them in a way with sufficient strength to support the two projectors.
