*1 When the standby mode is set to eco, network functions such as power on over the LAN network will not operate, and the serial output termi-
nal cannot be used. Also, only certain commands can be received for external control using the serial terminal.
*2 easurement, measuring conditions, and method of notation all comply with ISO 21118 international standards.
*3 Up to a total of ±55° during simultaneous horizontal and vertical correction.
*4 WUXGA resolution is supported only when the signals are compliant with VESA CVT-RB (Coordinated Video Timing-Reduced Blanking).
*5 With legs at shortest position.
*6 Excluding the optional lens.
*7 Average value (excluding the optional lens). ay differ depending on models.
*8 The operating temperature range is 0 °C to 40 °C (32 °F to 104 °F) when the FAN CON TROL is set to HIGH A LTITUDE ODE (for altitudes from 1,400 m
to 2,700 m (4,593 ft to 8,858 ft) above sea level). When the projector is used with the ET-SFR510 Smoke Cut Filter, the operating temperature
range is 0 °C to 35 °C (32 °F to 95 °F), and the projector cannot be used in places at high altitude. The operating temperature range is 0 °C to
40 °C (32 °F to 104 °F) when the ET-LAD510P/LAD510PF lamp is mounted and the projector is used in portrait configuration. The operating tem-
perature range is 0 °C to 35 °C (32 °F to 95 °F) when the FAN CON TROL is set to HIGH A LTITUDE ODE (for altitudes from 1,400 m to 2,700 m (4,593 ft
to 8,858 ft) above sea level). When the projector is used with the ET-SFR510 Smoke Cut Filter, the operating temperature range is 0 °C to 30 °C
(32 °F to 86 °F).

• 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.

Projection distance for 4:3 aspect ratio screen
(ET-D75LE6/D75LE10/D75LE20/D75LE30/D75LE40/D75LE8/D75LE50)
Unit: feet
Unit: meters
• The value for L (distance to screen) varies slightly within ±5% depending on the zoom lens characteristics.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
• When vertical keystone correction is used, the image is corrected in the direction that reduces its projected size.
NOTE: When the ET-D75LE50 is mounted, the optical lens shift function cannot be used.

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) × 0.0207 – 0.0566
maximum L (m) = (diagonal screen size in inches) × 0.0248 – 0.0736
minimum L (m) = (diagonal screen size in inches) × 0.0290 – 0.0857
maximum L (m) = (diagonal screen size in inches) × 0.0375 – 0.1085
minimum L (m) = (diagonal screen size in inches) × 0.0371 – 0.0832
maximum L (m) = (diagonal screen size in inches) × 0.0540 – 0.1162
minimum L (m) = (diagonal screen size in inches) × 0.0536 – 0.1131
maximum L (m) = (diagonal screen size in inches) × 0.1039 – 0.1765
minimum L (m) = (diagonal screen size in inches) × 0.1026 – 0.1577
maximum L (m) = (diagonal screen size in inches) × 0.1635 – 0.1615
minimum L (m) = (diagonal screen size in inches) × 0.1640 – 0.3862
maximum L (m) = (diagonal screen size in inches) × 0.3072 – 0.3598

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 24 Hz to 120 Hz, and a dot clock of
162 MHz maximum can be input.
NOTE: The native resolution of this projector is 1,400 × 1,050 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 the D, 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.
• When using two or more units:
1) Set different IDs for each unit.
2) Designate only one unit as RESPONSE (ID ALL) ON and the rest as RESPONSE (ID ALL) OFF.
3) Each group should have only one RESPONSE (ID GROUP) ON and the rest should be RESPONSE (ID GROUP) OFF.

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 500 mm (1 feet 8 inches) or more around the projec-
tor’s exhaust openings.
3. Do not stack projector units directly on top of one another. f two units must be stacked for back-
up use in ordinary projection, use a method as shown below and provide ample space between the
units to ensure that exhaust heat does not accumulate near the intake opening or around the units.
Dual stacked projection is not recommended.
4. 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.
5. 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.
6. f the projector is installed in an enclosed space, ensure that the temperature of the air surrounding
the projector is between 0°C and 40°C (32°F and 104°F). Also make sure that the projector’s intake
and exhaust openings are not blocked. Even though the air surrounding the projector is 40°C
(104°F) or less, if hot exhaust air accumulates inside the space, it may cause the projector’s protec-
tive circuit to interrupt projector operation. Pay particular attention to the surrounding temperature
conditions when planning the installation.
7. f the projector is not to be set on the floor using adjuster legs, install it by using the five ceiling-
mount screw holes (screw diameter: M6, length of each screw hole in the projector: 30 mm (1-3/16
inches)). Provide a space of 5 mm (3/16 inches) or more between the projector and the mounting
surface by inserting metal spacers.

Operating the projector continuously
1. f the projector is to be operated continuously one week, use the quad-lamp optical system’s alternating
lamp operation (lamp relay) function. The projector cannot be operated continuously one week in quad-
lamp mode. Allow a minimum of two hours per day of non-operation time for each lamp if the projector
is to be operated continuously for more than one week.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods.
