Caution:
• All construction work should be done by a qualified technician.
• When mounting to the ceiling, use the special mounting bracket. To prevent the projector from swaying or drop-
ping, attach the wire that is included with the projector between the mounting bracket and the ceiling.

Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3
minimum L (m) = (diagonal screen size in inches) × 0.0345 – 0.0233
maximum L (m) = (diagonal screen size in inches) × 0.0414 – 0.0237
OTE:
Distances calculated with the above equations will include a slight error.

OTE:
• The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
* Lens performance cannot be guaranteed for projection sizes larger than 11.0 m (36.1 ft).

List of compatible signals
The signals that can be input to this projector are shown in the table below. Horizontal scanning fre-
quencies of 15 kHz to 100 kHz, vertical scanning frequencies of 50 Hz to 100 Hz, and a dot clock of
140 MHz maximum can be input.
OTE: The native resolution of this projector is 1,024 × 768 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.
