To prevent personal injury
•
Isolate electrically before replacing the lamp or lamp house. Caution: Hot lamp (house).
•
Caution: High pressure lamp may explode if improperly handled. Refer servicing to qualified service personnel.
•
To prevent injury and physical damage, always read this manual and all labels on the system before inserting the lamp casing,
connecting to the wall outlet or adjusting the projector.
•
To prevent injury, take note of the weight of the projector. Minimum 4 persons are needed to carry the projector.
•
To prevent injury, ensure that the lens, exhausting system and all cover plates are correctly installed. See installation proce-
dures.
•
Warning: high intensity light beam. NEVER look into the lens ! High luminance could result in damage to the eye.
•
Before attempting to remove any of the projector’s covers, you must turn off the projector and disconnect from the wall outlet.
•
When required to switch off the projector, to access parts inside, always disconnect the power cord from the power net and
unplug the power cord from the UPS INLET.
•
Do not place this equipment on an unstable cart, stand, or table. The product may fall, causing serious damage to it and
possible injury to the user.
•
It is hazardous to operate without lens or shield. Lenses, shields or ultra violet screens shall be changed if they have become
visibly damaged to such an extent that their effectiveness is impaired. For example by cracks or deep scratches.
•
Warning: Protection from ultraviolet radiation: Do not look directly in the light beam. The lamp contained in this product is
an intense source of light and heat. One component of the light emitted from this lamp is ultraviolet light. Potential eye and skin
hazards are present when the lamp is energized due to ultraviolet radiation. Avoid unnecessary exposure. Protect yourself and
your employees by making them aware of the hazards and how to protect themselves. Protecting the skin can be accomplished
by wearing tightly woven garments and gloves. Protecting the eyes from UV can be accomplished by wearing safety glasses
that are designed to provide UV protection. In addition to the UV, the visible light from the lamp is intense and should also be
considered when choosing protective eye wear.
•
Exposure to UV radiation: Some medications are known to make individuals extra sensitive to UV radiation. The American
Conference of Governmental Industrial Hygienists (ACGIH) recommends occupational UV exposure for an-8 hour day to be
less than 0,1 micro-watts per square centimeters of effective UV radiation. An evaluation of the workplace is advised to assure
employees are not exposed to cumulative radiation levels exceeding these government guidelines.
WARNING: Never look into the exhaust output. High luminance and UV radiation could result in damage to
the eye. The installation of an exhaust system is mandatory before operating the projector.
To prevent fire hazard
•
Do not place flammable or combustible materials near the projector!
•
Barco large screen projection products are designed and manufactured to meet the most stringent safety regulations. This
projector radiates heat on its external surfaces and from ventilation ducts during normal operation, which is both normal and
safe. Exposing flammable or combustible materials into close proximity of this projector could result in the spontaneous ignition
of that material, resulting in a fire. For this reason, it is absolutely necessary to leave an “exclusion zone” around all external
surfaces of the projector whereby no flammable or combustible materials are present. The exclusion zone must be not less
than 40 cm (16”) for all DLP Cinema projectors. The exclusion zone on the lens side must be at least 5 m. Do not cover the
projector or the lens with any material while the projector is in operation. Keep flammable and combustible materials away from
the projector at all times. Mount the projector in a well ventilated area away from sources of ignition and out of direct sun light.
Never expose the projector to rain or moisture. In the event of fire, use sand, CO2 or dry powder fire extinguishers. Never use
water on an electrical fire. Always have service performed on this projector by authorized Barco service personnel. Always
insist on genuine Barco replacement parts. Never use non-Barco replacement parts as they may degrade the safety of this
projector.
•
Slots and openings in this equipment are provided for ventilation. To ensure reliable operation of the projector and to protect
it from overheating, these openings must not be blocked or covered. The openings should never be blocked by placing the
projector too close to walls, or other similar surface. This projector should never be placed near or over a radiator or heat
register. This projector should not be placed in a built-in installation or enclosure unless proper ventilation is provided.
•
Projection rooms must be well ventilated or cooled in order to avoid build up of heat. It is necessary to vent hot exhaust air from
console to the outside of the building. The minimum exhaust airflow requirement is 6,65 m3/min (235 CFM).
•
Let the projector cool completely before storing. Remove cord from the projector when storing.
•
Heat sensitive materials should not be placed in the path of the exhausted air or on the lamp house.

To prevent projector damage
•
This projector has been designed for use with a specific lamp (house) type. See installation instructions for its correct type.
•
The air filters of the projector must be cleaned or replaced on regular base (a "clean" booth would be monthly-minimum).
Neglecting this could result in disrupting the air flow inside the projector, causing overheating. Overheating may lead to the
projector shutting down during operation.
•
The projector must always be installed in a manner which ensures free flow of air into its air inlets and unimpeded evacuation
of the hot air exhausted from its cooling system.
•
In order to ensure that correct airflow is maintained, and that the projector complies with Electromagnetic Compatibility (EMC)
requirements, it should always be operated with all of it’s covers in place.
•
Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from
overheating, these openings must not be blocked or covered. The openings should never be blocked by placing the product
on a bed, sofa, rug, or other similar surface. This product should never be placed near or over a radiator or heat register. The
device should not be placed in a built-in installation or enclosure unless proper ventilation is provided.
•
Ensure that nothing can be spilled on, or dropped inside the projector. If this does happen, switch off and unplug the mains
supply immediately. Do not operate the projector again until it has been checked by qualified service personnel.
•
Do not block the projector cooling fans or free air movement around the projector. Loose papers or other objects may not be
nearer to the projector than 10 cm (4") on any side.
•
Do not use this equipment near water.
•
Proper operation of the cooling circuit can only be guaranteed in table mounting. It is not allowed to use the projector in another
position. See installation procedure for correct installation.
•
Special care for Laser Beams: Special care should be used when DLP projectors are used in the same room as high power
laser equipment. Direct or indirect hitting of a laser beam on to the lens can severely damage the Digital Mirror DevicesTM in
which case there is a loss of warranty.
•
Never place the projector in direct sun light. Sun light on the lens can severely damage the Digital Mirror DevicesTM in which
case there is a loss of warranty.
•
Save the original shipping carton and packing material. They will come in handy if you ever have to ship your equipment. For
maximum protection, repack your set as it was originally packed at the factory.
•
Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning. Never use strong solvents, such as thinner or benzine, or abrasive cleaners, since these will damage the cabinet.
Stubborn stains may be removed with a cloth lightly dampened with mild detergent solution.
•
To ensure the highest optical performance and resolution, the projection lenses are specially treated with an anti-reflective
coating, therefore, avoid touching the lens. To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent
solution, or thinner.
•

Let the projector acclimate to the ambient temperature after unpacking. Neglecting this may result in a startup
failure of the Light Processor Unit.
Cooling requirements
The projector is fan cooled and must be installed with sufficient space mainly in the front of the projector head, minimum 20 cm (8
inch) to ensure sufficient air flow. It should be used in an area where the ambient temperature, as measured at the projector head
air inlet and at the power unit air inlet, does not exceed +35°C (+95°F).
The installation of an exhaust system is MANDATORY. The installed exhaust blower must remove an air volume of minimum 6,65
m3/min (235 CFM).
Power requirements
The DP2K-20C digital projector operates from a nominal mono phase power net with a separate earth ground PE. The DP2K-20C
digital projector requires 200–240 VAC, 50–60 Hz, 26 amps at 200 VAC with a separate earth ground PE. A label on the projector
indicates the nominal line voltage for which the projector was set at the factory.
The power cord required to connect the projector with the power net is not delivered with the projector. It is the responsibility of the
customer to provide the correct type of power cord. The cross-sectional area of the conductors in the power supply cord shall not
be less than 4 mm² or 10 AWG, minimum 300V.
To protect operating personnel, the National Electrical Manufacturers Association (NEMA) recommends that the instrument panel
and cabinet be grounded. In no event shall this projector be operated without an adequate cabinet ground connection.
The AC supply must be installed by a qualified electrician in conformance to local codes. Hardware, wire sizes and conduit types
must comply with local codes.
UPS requirements
The Uninterruptible Power Supply (UPS), also known as a Continuous Power Supply (CPS), must have an output voltage of 200-
240V at 50-60Hz and must be capable of delivering an output current of 5,5 amperes.
The connection between the UPS unit and the UPS inlet of the projector must be done with a certified AC power supply cord of
minimum 0,75 mm² or 18 AWG and minimum 300V.
CAUTION: The 200–240V power outlet (UPS OUTLET) of the projector may not be used to provide the UPS
unit with power! The UPS OUTLET of the projector may only be used for connection to the UPS INLET of the
projector.
The DP2K-20C digital projector does not have a built in UPS unit.
Projector weight
Do not underestimate the weight of the Barco DP2K-20C digital projector. The projector weights about ±102 kg (±225 lb.) without
lens. Be sure that the pedestal on which the projector has to be installed is capable of handling five (5) times the complete load of
the system.
Barco offers a pedestal for the DP2K-20C digital projector. This universal pedestal allows a solid and easy
setup of the projector. The universal pedestal has a separate compartment to install the UPS unit for the

Installation process overview
Let the projector acclimate to the ambient temperature after unpacking. Neglecting this may result in a startup
failure of the light processor unit.
Set up from A to Z
After you have unpacked and checked the projector you can start with the installation process of your DP2K-20C digital projector.
This chapter gives you an overview of all the different stages in the installation process which you have to follow to set your DP2K-
20C digital projector up and running. Each stage is briefly described and refers to more detailed step by step procedures in this
manual. Use this overview as a checklist to ensure that you have followed all stages in the setup process of your DP2K-20C digital
projector.
Set up from A to Z
1. Check if all installation requirements are fulfilled such as the environment conditions of the installation area, capacity of the
exhaust system, electrical facilities, etc. Note that a solid pedestal is required to support the projector head. For more info see
chapter "Installation requirements", page 10.
2. Physical installation of the projector upon its pedestal and connecting the air outlet of the projector with the exhaust system.
Note that the exhaust system is MANDATORY. See chapters "Physical installation", page 15, and "Installation of the exhaust
system", page 19.
3. Electrical connection with the power net. See chapter "Connecting the projector with the power net", page 20.
4. Installation of a suitable UPS unit or bypass the power in and outlet for the projector electronics. See chapters "Connecting
a UPS with the projector electronics", page 24 or "Power loop through to the projector electronics", page 22.
5. Installation of the xenon lamp in case the xenon lamp is not installed in the lamp house yet. To install the xenon lamp the lamp
house has to be removed from the projector. To install the xenon lamp correctly and in a safe manner, see the detailed step by
step procedures in the chapter "Installation of the Xenon lamp", page 34.
6. Installation of the lens. First select an appropriate lens which throw ratio covers the screen size and the projector - screen
distance. Then install the lens in the lens holder of the projector. For more information about available lenses, lens selection and
lens installation see chapter "Lenses & lens holder", page 45.
7. Installation of the Communicator Touch Panel. See chapter "Installing the touch panel interface", page 70.
8. Alignment of the projected image on the screen. The projector can now be switched on to project its first image (test pattern)
on the screen. Then the image can be aligned with the screen size of the application. Follow the next steps to achieve that:
a) Place the ON/OFF switch of the projector in the ”I” position. As a result the projector starts to initialize. The status lights of
the projector lights up GREEN once the projector is initialized.
b) Press the STANDBY button on the local keypad to activate the lamp.
c) Press the DOWSER button on the local keypad to open the dowser of the projector. The dowser is open if the color of the
DOWSER button is GREEN.
d) Press the TEST PATTERN button on the local keypad to project one of the internal test patterns of the projector on the screen.
e) Use the lens ZOOM, SHIFT and FOCUS buttons on the local keypad the match the projected image with the screen. Tilt the
projector in case you can not SHIFT the image completely upon the screen. See "Lens shift, zoom & focus", page 52.
9. Resetting the lamp parameters. The “LAMP INFO” parameters which are stored on the controller board of the projector MUST
be updated after each installation of an xenon lamp inside the lamp house. Neglecting this update will result in poor performance
and short life time of the xenon lamp. See chapter "Resetting the lamp parameters", page 42.
10.Realignment of the xenon lamp in its reflector. For optimal performance of the xenon lamp it is required to realign the lamp
after installation in the lamp house. See "Realignment of the lamp in its reflector", page 43 for more information.
11.Adjusting the light path. Normally the lens holder and the convergence of the projector is perfectly adjusted at the factory.
Nevertheless, some applications require a readjustment of the lens holder, convergence or both. See procedure "Scheimpflug
adjustment", page 53, to adjust the Scheimpflug and see chapter "Convergence ", page 115 to adjust the convergence of the
light path.
12.Registration of the projector. The DP2K-20C digital projector is DCI compliant and should be registered by Barco. Therefore,
the digital certificate inside the projector will be used to secure encryption key communication between the projector and the rest
of the theatre system (server and theatre management system). For more info see chapter "Projector registration", page 77.
13.Projection of a digital cinema movie. Apply a single or dual channel SMPTE or DVI source to the input ports of the projector
and start up the projector. See "Source input ports of the DP2K-20C projector", page 64 and chapter "Starting up", page 73. Use
the Communicator Touch Panel to configure the applied source. See the user guide of the Communicator Touch Panel for more

Projector centering
1. If the projector is standalone in front of the port window, center the projector with the theatre screen (see ref A image 3-2).
2. If a film projector is already present (projector will be off-center), try to optimize aim (see ref B image 3-2).
Note:
Unlike film projectors, it is best to keep the projector lens surface as parallel to the screen as possible, even if it is
significantly above the screen center.
The off-center position slightly increase side keystone, but will minimize horizontal lens offset required.

4. Later, when the projector is up-and-running, adjust precise image geometry and placement.
Projector tilting
In an ideal installation, the DP2K-20C lens surface is centered with and parallel to the screen. This orientation helps to ensure
optimized lens performances with minimal offset. If this position is not possible (such as when the projector is significantly higher
than the center of the screen), it is better to rely on offset rather than extra tilt.
1. Before adjusting tilt, make sure the projector is as well-centered with the theatre screen as possible for your installation area.
2. Check with theatre personnel for the degree of screen tilt, or measure this incline with a protractor at the screen.
3. Tilt the projector to closely match this screen tilt angle as follows:
-
Loosen the nuts (A), using a wrench of 17 mm, on the threaded rod.
-
Adjust the height of the legs until the projected image matches the projection port window and the screen tilt.
-
Secure the leg height by tightening the nuts (A).

Lens selection
How to select the right lens for your application ?
1. Determine the required screen width (SW).
2. Determine the position of the projector in the projection room with regard to the screen and measure the projector-screen distance
(PD).
3. Use the lens formulas (see "Lens formulas", page 48) to find the best corresponding PD with regard to the measured projector-
screen distance for the required screen width SW.
Tip:
Divide PD by SW to determine the approximate throw ratio. Choose a Lens, which captures the calculated throw ratio.
Use the lens formula of the chosen Lens to recalculate exactly.

Lens shift, zoom & focus
Motorized lens adjustment
The DP2K-20C projector is equipped with a motorized lens shift functionality and a motorized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the DMD which result in a shifted image on the screen (Off-Axis). A 100% shift means that
the centre point of the projected image is shifted by half the screen size. In other words, the centre point of the projected image falls
together with the outline of the image in an On-Axis projection. Due to mechanical an optical limitations the shift range is limited as
well.
All DC2K lenses have a shift range of 50% up/down and 15% left/right. This range is valid for all throw ratios. Only the 0.98" DC2K
Zoom (1.95–3.2 : 1) lenses with item numbers R9855934 and R98559341 have a larger shift range of 128% up/down.
How to shift the lens of the DP2K-20C?
1. Use the up and down arrow keys on the local keypad to shift the lens vertically and use the left and right arrow keys on the
local keypad to shift the lens horizontally.
Image 5-13
How to zoom in or out?
1. Is the projector equipped with a motorized zoom & focus?
If yes, use the “+” and “-” zoom keys on the local keypad to zoom in or out.
Image 5-14
If no, use the zoom barrel on the lens to zoom in or out.
How to focus?
1. Is the projector equipped with a motorized zoom & focus?
If yes, use the “+” and “-” focus keys on the local keypad to focus the image on the screen.
Image 5-15
If no, use the focus barrel on the lens to focus the image on the screen.

Scheimpflug adjustment
What has to be done ?
The lens holder has to be adjusted so that the “sharp focus plane” of the projected image falls together with the plane of the screen
(Fp1→Fp2). This is achieved by changing the distance between the DMD plane and the lens plane (Lp1→Lp2). The closer the lens
plane comes to the DMD plane the further the sharp focus plane will be. It can sometimes happen that you won’t be able to get a
complete focused image on the screen due to a tilt (or swing) of the lens plane with respect to the DMD plane. This is also known
as Sheimpflug’s law. To solve this the lens plane must be placed parallel with the DMD plane. This can be achieved by turning the
lens holder to remove the tilt (or swing) between lens plane and DMD plane (Lp3→Lp4).

Scheimpflug principle
Scheimpflug principle
The "plane of sharp focus" can be changed so that any plane can be brought into sharp focus. When the DMD plane
and lens plane are parallel, the plane of sharp focus will also be parallel to these two planes. If, however, the lens
plane is tilted with respect to the DMD plane, the plane of sharp focus will also be tilted according to geometrical and
optical properties. The DMD plane, the principal lens plane and the sharp focus plane will intersect in a line below the
projector for downward lens tilt.

The DP2K-20C projector can be connected to a LAN (local area network) using one of the Ethernet ports (1). Once connected to the
LAN, users can access the projector from any location, inside or outside (if allowed) their company network using the Communicator
software. This software locates the projector on the network if there is a DHCP server or the user can insert the correct IP-address to
access the projector. Once accessed, it is possible to check and manipulate all the projector settings. Remote diagnostics, control
and monitoring of the projector can then become a daily and very simple operation. The network connectivity allows detection of
potential errors and consequently improve service time.
As there is a need to daisy chain projectors when they are on an Ethernet network, an Ethernet switch is built in. the incoming
network is hereby available for the internal PC and for the next device in the chain. In this way a ’star’ network interconnection can
be avoided. The switch used is a stand alone 10/100/1000Mbit Ethernet switch. This assures no influence on the network speed.
RS232 IN
This female DB-9 connector allows you to use a standard serial cable up to 10 meter to connect the touch panel interface with the
projector. Note that the RS232 protocol is used on this connection.
RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the commu-
nication path between two devices using either D-SUB 9 pins or D-SUB 25 pins connectors. This standard is used for
relatively short-range communications and does not specify balanced control lines. RS-232 is a serial control standard
with a set number of conductors, data rate, word length and type of connector to be used. The standard specifies com-
ponent connection standards with regard to computer interface. It is also called RS-232-C, which is the third version
of the RS-232 standard, and is functionally identical to the CCITT V.24 standard. Logical ’0’ is > + 3V, Logical ’1’ is < -
3V. The range between -3V and +3V is the transition zone.
GENERAL PURPOSE IN/OUT
This 37 pin connector can be used to send or receive trigger signals from other devices. These input/output pins can be programmed
by macros created on the Communicator touch panel. See user’s guide of the Touch panel, section Macro editor, for more informa-
tion about this functionality. Note that the General Purpose Inputs accept 24 volt maximum.

About General Purpose Inputs & Outputs (GPIO)
General Purpose inputs
Eight (8) opto-isolated general purpose inputs are available, six (6) free and 2 dedicated inputs. These inputs are used to trigger the
execution of macro files. For more explanation about the association of a macro to a GPI, consult the user guide of the Communicator
touch panel.
Input voltage
The inputs can be directly driven from a TTL or CMOS output.
•
Minimum voltage : Vmin = 3,3 V
•
Maximum voltage : Vmax = 24 V
External power supply
When interfacing with contact closure outputs, an external power supply needs to be provided. Depending upon the configuration a
suitable pull-up resistor needs to be added as well.

Cables
When long cable connections are required the use of shielded cables with twisted pairs is recommended. One twisted pair is to be
assigned to each GP Input pair.
How to make the connection
When the power supply used to provide the DC voltage is isolated from ground (for example in the case of an AC adapter) it is
recommended that the minus pole of that power supply is connected to ground (or to the projector chassis). This will avoid high
common mode voltages at the projector GP Inputs. If that same power supply is used for other parts of the system, take care not to
create ground loops. In any case when shielded cables are used that shield should be connected to the projector chassis.
General Purpose outputs
Eight (8) opto-isolated outputs are available, where seven are general purpose and one for a fixed purpose. The seven general
purpose outputs can be controlled via software while the fixed output provides the 3D output reference. When this output is closed
(current is flowing), then the system is OK.
About an output
The output can generate a falling edge, rising edge, toggle or continuous toggle.
•
Generate Falling Edge – generate a falling edge on the external GPO port if the present state of the output is high. If the
present state of the external GPO is low, no edge will be generated.
•
Generate Rising Edge – generate a rising edge on the external GPO port if the present state of the output is low. If the present
state of the external GPO is high, no edge will be generated.
•
Generate Toggle – generate a toggle on the external GPO port. If the present state of the output is low, a rising edge will be
generated, followed by a falling edge. If the present state of the output is high, a falling edge will be generated, followed by a
rising edge. The rate of toggle will be the vertical sync rate (edge transition at each vsync).
•
Generate Continuous Toggle - This command will generate a continuous toggle of the external GPO port. This toggle will
continue until a Generate Falling Edge, Generate Rising Edge, or Generate Toggle command is received. The rate of toggle
will be the vertical sync rate (edge transition at each vsync).

7.1
Introduction
Communicator Touch Panel for digital cinema projectors
The Communicator Touch Panel is designed for multi-user command and control, the Communicator enables users to learn quickly
and operate efficiently - using an elegant and flexible touch panel interface. The interface’s commonality means that operators
can intuitively use any model in the product line, without restriction, and its user-friendly nature translates directly into a short and
enjoyable learning curve.
Image 7-1
Flexible touch panel interface
The touch panel interface can be mounted upon a swivel arm which easily fits on top of the DP2K-20C projector. One central locking
mechanism of the swivel arm allows an instant fixation of the touch panel interface in any position.
The touch panel interface can also be installed further away from the DP2K-20C projector. For that you can use a serial (RS232)
cable up to 10 meter or an Ethernet cable up to 50 meter to allow a direct data communication between the DP2K-20C projector
and the Communicator Touch Panel.
The touch panel interface can also be connected with a Local Area Network (LAN) just like the DP2K-20C projector. In this case
both devices can communicate with each other as well.
The touch panel interface requires a +12 VDC voltage, 1,5 ampere. The use of a separate +12 VDC adaptor (1,5 ampere minimum)
is required.

Introduction
Overview
The current projector is DCI compliant and should be registered by Barco. Therefore, the digital certificate inside the projector will
be used to secure encryption key communication between the projector and the rest of the theatre system (server and theatre man-
agement system). The film distributor will send keys to the theatre that are unique for the installed trusted digital cinema equipment
of that theatre. The film distributor will find its information about a theatre in the same database as where the projector is registered.
Barco plays as an intermediate station between the theatre and the film distributor.
Once a projector is registered, the uploaded data can be changed via the update procedure.
