*1 When the standby mode is set to eco, network functions such as power on over the LA network will not operate. Also, only certain com-
mands can be received for external control using the serial terminal.
*2 Measurement, measuring conditions, and method of notation all comply with ISO 21118 international standards.
*3 WUXGA resolution is supported only when the signals are compliant with VESA CVT-RB (Coordinated Video Timing-Reduced Blanking).
*4 With legs at shortest position.
*5 Operation range differs depending on environments.

Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16:10
L (m) = (diagonal screen size in inches) × 0.0112 – 0.0367
Aspect ratio 16:9
L (m) = (diagonal screen size in inches) × 0.0115 – 0.0378

Distances calculated with the above equations will include a slight error.

Installable angle
nstall the projector at an angle within the range shown below.
• Vertical direction
The projector may be installed at a vertical
angle of ±20°.
• Horizontal direction
The projector may be installed at a horizontal angle
of ±10°.

List of compatible signals
The signals that can be input to this projector are shown in the table below. Horizontal scanning fre-
quencies of 25 kHz to 80 kHz (15 kHz to 100 kHz for RGB signals), vertical scanning frequencies of 50
Hz to 120 Hz (50 Hz to 100 Hz for RGB signals), and a dot clock of 162 MHz maximum (140 MHz max-
imum for RGB signals) can be input.
OTE: The native resolution of this projector is 1,280 × 800 pixels. If the display resolution of the input signal is different from the
native resolution, image compression or expansion will be used to convert the input signal to a level within the native resolution.

Serial connector
The serial connector complies with RS-232C. To control the projector from a personal computer, com-
mands must be input through communication software, based on the format and satisfying the commu-
nication conditions shown below.
Basic format
Transmission from the computer begins with STX, then command, parameter, and ETX are sent in this
order. Add parameters according to the details of control.

CAUTIO
• It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 sec-
onds, then try sending or receiving again.
• When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector before sending the next
command.
• Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for command response to 10
seconds or more.

otes on projector placement and operation
The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
following precautions.
1. Never place objects on top of the projector while it is operating.
2. Make sure there is the unobstructed space as shown below or more around the projector’s exhaust
openings. n addition to this space, also ensure that there is a sufficient work space for removing
and installing the lamp, air filter and other parts.
3. Make sure that nothing blocks the projector’s air intake and exhaust openings. Also, install the pro-
jector so that cool or hot air from other air conditioning equipment does not flow directly toward the
projector’s air intake or exhaust openings.
4. Do not install the projector in an enclosed space. f it is necessary to install it in an enclosed
space, add a separate ventilation system. f ventilation is insufficient, hot air will accumulate at the
intake opening. This may cause the projector’s protective circuit to interrupt projector operation.

Operating the projector continuously
1. f the projector is to be operated continuously 6 hours or more, lamp replacement cycle duration
becomes shorter.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods (one hour or less).
