lens characteristics.

When the shortest projection distance is
used, a small amount of distortion may
occur in the image due to the zoom lens
characteristics.

Projection size

(diagonal)

Height from the edge of screen

to centre of lens (H)

Projection distance (L)

Min (wide) Max (telephoto)

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) x 0.0292 – 0.036
maximum L (m) = (diagonal screen size in inches) x 0.0351 – 0.044

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 ±30°.

• Vertical direction

The projector may not be angled horizontally.

Computer data compatibility

This projector accepts up to 91 kHz horizontal scanning frequency and 162 MHz dot clock.

NOTE: Pixel thinning is applied to signals that exceed a dot clock frequency of 100 MHz. The display resolution of this projector is 1,024 x 768

pixels. Input signals that exceed this resolution will be converted to 1,024 x 768 pixels.

List of compatible signals

1. The “i” appearing after the resolution indicates an interlaced signal.

2. The following symbols are used to indicate picture quality.

AA Maximum picture quality can be obtained.

A Signals are converted by the image processing circuit before picture is projected.

B Signals are compressed by the image processing circuit before picture is projected.

3. When 750 (720)/60p or 750 (720)/50p signals are input to a computer input terminal, images are projected in the WIDE750 (720) format. Be sure

to run the auto setup function.

PT-LB75

Portable LCD Projector

As of October 2008 < 6 >

Serial connector

The serial connector complies with RS-232C. To control the projector from a personal computer, com­mands must be input through communication software, based on the format and satisfying the commu­nication conditions shown below.

Pin assignments and signal names

Communication conditions (factory setting)

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
command response to 10 seconds or more.

NOTE:

If a wrong command is received, the projector will send an ER401 command to the computer.
When sending commands without parameters, a colon (:) is not necessary.

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 an unobstructed space of 150 mm (5-29/32˝) or more around the projector’s
exhaust openings.

3. If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the
projector is between 0°C/32°F and 35°C/95°F. Also make sure the projector’s intake and exhaust
openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
not sucked into the intake openings.

Direction of Air Intake and Exhaust

Operating the Projector Continuously

1. If the projector is to be operated continuously 10 hours or more, lamp replacement cycle duration
becomes shorter.

periods (one hour or less).
