Keystone
Keystone distortion
Normal
Keystone is the distortion of a projected image that usually creates a
wider top than bottom. Aiming a projector upward on a wall
rather than straight at a wall creates this distortion. Use the 

 or 
buttons on the slide bar to correct this keystone (trapezoidal)
distortion.
NOTE: The keystone feature is not available when the test pattern or the blueback is displayed.
NOTE: With the projector aimed directly at the screen the maximum keystoneangle that can be corrected is +/- 7.5 degrees.
Setting up for Double or Triple Stacking in Link
Mode
CAUTION: To prevent the projectors from falling, install them in a place andfasten them in a way with sufficient strength to support the two projectors.
NOTE: SW 1 Level and SW 2 Level of Switcher Control are not available on LinkMode. For double or triple 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 the supplied DVI-D cable to connect the RGB DIGITAL output
of the master projector to the RGB DIGITAL input (INPUT9 )of the
slave projector (the second and third stack) until all the projectors
are connected.
2-2. Next, using a commercially available, bi-directional RS-232C cable
connect the OPTION OUT terminal of the master projector to the
OPTION IN terminal of the slave projector(s) 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.

Operating Multiple Projectors with Remote Control
You can operate multiple projectors with the same remote control in wireless operation.
To do so:
1. Select [Menu] → [Projector Options] → [Setup] → [Page 5] → [Projector ID] and assign an ID number to each projector. See also page E-39.
2. On the remote control specify the ID number of the projector to be adjusted. Press and hold the CTL and press MENU (ADDRESS) button to
enter the ID number.
You can operate the projector assigned the same ID number as the remote control.
Projector ID= 01Projector ID= 02 Projector ID= 03
Remote Address = 03
You can daisy-chain multiple projectors and operate them separately with the same remote control in wired operation.
To do so:
1. Use the remote control cable to connect the REMOTE 2 Output of one projector to the REMOTE 2 Input of the next projector until all the projectors are
connected. Only one remote control cable is supplied with each projector.
2. Specify a unique projector ID for each projector.
3. Specify the same remote address as the projector ID to be adjusted.
NOTE: Specifying None for projector ID allows you to operate multiple projectors concurrently. However, some projectors may not synchronize to the otherprojectors.
Projector ID= 01 Projector ID= 02 Projector ID= 03
Remote Address = 03
