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
minimum L (m) = (diagonal screen size in inches) × 0.03338
maximum L (m) = (diagonal screen size in inches) × 0.03660
Aspect ratio 16:9
minimum L (m) = (diagonal screen size in inches) × 0.03429
maximum L (m) = (diagonal screen size in inches) × 0.03764
NOTE:
Distances calculated with the above equations will include a slight error.
Installable angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector may be installed at a vertical
angle of 10°.
• Horizontal direction
The projector may be installed at a horizontal
angle of 20°.

* STX and ETX are character chords. STX is 02 and ETX is 03 when expressed in hexadecimal.
Basic format
Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent
in this order. Add parameters according to the details of control.
CAUTION
• 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 seconds, 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 com-
mand response to 10 seconds or more.

* Do not send PON, POF or OSH commands continuously in a short period of time. Doing so may burst the lamp or shorten the lamp replacement
cycle.
* When a command that cannot be executed during standby mode is sent, the projector will send an ER401 command in reply.

Notes 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. In 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. If it is necessary to install it in an enclosed
space, add a separate ventilation system. If ventilation is insufficient, hot air will accumulate at the
intake opening. This may cause the projector’s protective circuit to interrupt projector operation.
Direction of air intake and exhaust

Operating the projector continuously
1. If the projector is to be operated continuously 22 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).
