How The Pro

ectors Work 

Roadster S+ series and Mirage S+ series accept data/graphics and video inpu t signals for projection on to front or rear flat screens. High brightness light is generated by an internal Bubble lamp, then modulated by three DMD (digital micromirror device) panels that provide digitized red, green or blue color information. Light from the “on” pixels of each panel is reflected, converged and then projected to the screen through the front lens, where all pixels are superimposed as a sharp full-color image.

INSTALLATION & SETUP

Before You Begin

 Always align to the fixed projector. In floor-mount or table-mount (i.e., non-

hoisted) stacks, you will align to the bottom projector as shown in drawings below. In hoisted stacks, align to the top projector.

 Leg nuts must be loosened before alignment, otherwise the stacking mounts will

not turn and allow movement of the projector.

STEP 1 '

STEP 2 '

STEP 3 '

STEP 4 '

STEP 5 '

Position the first image (fixed projector)

Position the fixed projector’s image as desired and align the other image(s) to it as described below.

Display the grid test pattern

To distinguish each image, enable “Red” for one display and “Green” for the other. See 3.3, Using the Keypads if you need help enabling colors.

Adjust zoom and focus

Minimize each projector’s zoom and images are in focus.

Try aligning the two grid patterns

Adjust zoom and offset on the top projector to precisely move its test pattern display on to the bottom test pattern. When properly aligned, all red/green grid lines in the combined image will turn yellow.

• If all lines are well-aligned, skip to STEP 7 to lock all stacking mounts.

• If alignment needs improvement, proceed with the next step.

Align the center lines of the grid

Turn the (2) rear stacking mount wheels to move the top projector as necessary for well-aligned center lines. Use a screwdriver in the holes around the rim of each adjusting wheel for better leverage and control.

2-10

HOW TO MOVE THE IMAGE:

Turned independently, each stacking mount acts as a pivot point for the opposite edge of the display (see right). For example, turn the right mount to tilt the left portion of the image up or down, and turn the left mount to tilt the right portion of the image up or down. Turn together to raise or lower the top image like an offset adjustment, or turn the front stacker.

IF THE CENTER LINES FORM AN “X”: This indicates that the projectors (and images)

are slightly tilted in relation to one another. Turn one mount to raise one side, and/or turn the other mount to lower other side. See Figure 2.15.

Roadster / Mirage S+ User’s Manual

Figure 2.15. Adjustment Directions (Tilt)

IF THE CENTER LINES ARE PARALLEL BUT MISALIGNED:

• If centerlines are out by the same amount from top and bottom – use offsets (on top projector) to bring the centerlines into alignment.

Front Screen Installations

While there are two basic screen types, flat and curved, generally flat screens are recommended for this projector (Figure 2.17)X. Flat screens offer a gain of about 1 with a viewing angle just less than 180°. Incident light reflects equally in all directions so the audience can see the display from various angles. Because of the low gain, flat screens are most effective when ambient lighting is reduced, although this difference may be negligible given the high brightness output from this projector.

Figure 2.17. Audience Coverage with Flat Screen Figure 2.17

NOTE: Lenses for this projector are designed primaril y for use with flat scr eens, but the projector depth-of-field range allows the lens to be focused on curved screens as well. While focus remains sharp in the corners, there may be significant pincushion distortion, primarily at the top of the screen.

2-12

Rear Screen Installations

There are two basic types of rear screens: diffused and optical . A diffused screen has a surface which spreads the light striking it. Purely diffused screens have a gain of less than 1. The main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This increase at the front reduces the intensity in other areas. A viewing cone, similar to that of a curved front screen install ation, is crea ted.

Roadster / Mirage S+ User’s Manual

INSTALLATION & SETUP

Ambi

To summarize, optical screens are better suited for brightly lit rooms where the audience is situated within the viewing cone. Diffused screens may be better suited when a wide viewing angle is required but there is low ambient room lighting.

Screen Size '

Screen As

ect Ratio '

Screen size may vary from 4 feet (122 cm) to 45 feet (1372cm) diagonal, depending on the lens you are using. For instance, a 0.73:1 lens can produce a 5 foot (150 cm) to a 14 foot (548 cm) image size depending on the location of the projector, whereas a

4.5-7.3:1 zoom lens produces an 8 foot(160 cm) to 40 foot (438 cm) image size.

Choose a screen size appropriate for your lens and application. Keep in mind that if the projector will be used to display text information, the image size must allow the audience to recognize all text clearly. The eye usually sees a letter clearly if eye-totext distance is less than 150 times the height of the letter. Small text located too far from the eye may be illegible at a distance no matter how sharply and clearly it is displayed.

Ideally, to fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of its width to its height such as a 4:3 aspect. Standard video from a VCR has a 4:3 aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10 foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m).

Aspect ratio (Figure 2.18) describes the proportion of the screen and is expressed as the ratio of width to height, such as “4:3” or “5:4”. Although image size and image aspect ratio can both be adjusted quickly through projector software, it is still a good idea to choose a screen aspect ratio which is most appropriate for your intended applications.

Ideally, to exactly fill a screen with an image, the aspect ratio of the screen should correspond to the aspect ra ti o of the image, which depends on the source in use. For example, standard video from a VCR has a 4:3 ratio (approximately), whereas a high resolution graphics signal typically has a 5:4 aspect ratio. By default, images from your projector will be as large as possible and will maintain their aspect ratio.

Figure 2.18. Aspect

The SXGA+ (1400 x 1050) aspect ratio for the Roadster

Ratio

and Mirage models is 4:3.

ent Lighting '

Other Considerations '

The high brightness of this projector is well suited for locations where ambient lighting might be considered less than ideal for projection. Even a typical room or large auditorium fully lit with ceiling lights and windows rarely requires special attention. Contrast ratio in your images will be noticeably reduced only if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant.

In general, avoid or eliminate light sources directed at the screen. Other considerations and tips which can help improve your installation:

• Keep the ambient temperature constant and below 35°C (95°F). Keep the

projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry which may affect performance.

2.3 Projector Position and Mounting

Throw Distance '

• Keep the projector away from devices which radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers, elevators, etc.

• Choose the best screen size for the application. Since m ore mag n ifica tion reduce s brightness, use a screen size appropriate for the venue but not larger than required. Installing a large screen in a small room is similar to watching television at a close range; too large a screen can overpower a room and interfere with the overall effect. A good rule of thumb is to be no closer than 1.5 times the width of the screen.

Installation type, screen type, and lighting all affect where the projector is positioned. In addition, both throw distance (the distance between the pro jector and scre en) an d vertical position (the height of the projector in relation to the screen) must be determined for every new installation. Both depend on the screen size and lens type you are using. Make sure that the room can accommodate the required position of the projector for the chosen screen size.

Figure 2.19. Estimating Throw Distance

(SEE APPENDIX D)

For any installation, an accurate throw distance (TD) must be determined in order for the image to be of the right size for your screen–the farther the projector is from the screen, the larger the image. Throw distance is the distance between the projector’s front feet axes and the screen (Figure 2.19), and is roughly equal to the horizontal width of the screen multiplied by the throw ratio of the installed lens. Once you know your screen size and lens, you can estimate throw distance needed. For example:

• Screen Width = 10 feet

• Lens Type is 0.7:1

• Throw Distance (TD) = 10 feet x 0.7 = 7 feet

NOTES: 1) If your projector is slightly tilted in relation to the screen, typical for large venues or flown installations, throw distance still represents the smallest measurement between the screen and front feet. 2) For proper placement in an installation, always refer to the throw distance formula and/or chart for your lens as listed in Appendix D. Keep in mind that due to lens manufacturing tolerances for

THE VERTICAL POSITION of the projector in relation to the scre en also depen ds on the

size of the screen and the lens type. Correct vertical position helps ensure that the image will be rectangular in shape rather than keystoned (having non-parallel sides) and that image focus and brightness both remain optimized.

If necessary, vertical position of the image can be offset—that is, moved up or down in relation to lens center—by using the motorized offset function. Starting with no offset, the 1400 x 1050 image from this projector can be moved up or down by a maximum distance of 525 pixels, resulting in all of the image displayed above or below lens center. See Table 2.1 and Figure 2.20. NOTE: Not applicable to the fixed

0.73:1 lens.

THE HORIZONTAL POSITION of the image can be offset—that is, shift ed lef t or right

of lens center—by using the motorized offset function. Starting with no offset, the 1400 x 1050 image from this projector can be moved left or right by a maximum distance of 350 pixels, resulting in 75% of the image displayed to one side of lens center. See Table 2.1 and Figure 2.21.

INSTALLATION & SETUP

NOTES: 1) If the image becomes keystoned or exhibits uneven brightness, the projector may simply be too high or low in relation to the screen. 2) Recommended offset ranges can be exceeded, however this may affect image quality. 3) Simultaneous horizontal and vertical offset limits the adjustment range of each. 4) Offset can vary by ±7% and may be affected by the degree of zoom currently in use.

Tilting the Projector '

Figure 2.21. Maximum Horizontal

Offsets

The projector can be rotated and mounted at any vertical angle—i.e., you can tilt the face of the projector up or down as much as desired for your installation. Side-to-side tilt, however, must not exceed 15°. This limit ensures that the lamp in the projector operates properly and safely. Always vent exhaust air away from the lens.

For permanent ceiling mount installations, use the Christie ceiling mount fixture designed for your projector. For more information, contact your dealer.

Folded Optics '

2-16

Roadster / Mirage S+ User’s Manual

In rear screen applications (Figure 2.23)where space behind the projector is limited, a mirror may be used to fold the optical path. The position of the projector and mirror must be accurately set. Consult your dealer or Christie for details.

2.4 Source Connections

INSTALLATION & SETUP

Sources connect to the Input Panel located on the rear of the projector. As shown in Figure 2.24, the upper right corner (

INPUT 1) typically accepts an RGB signal from

an external analog RGB source, or it can also be used for YPbPr signals or additional video sources. Just to the left of the BNCs, the DVI-I connector (

INPUT 2) accepts

digital or analog display signals from a computer. Connect analog composite video at

INPUT 3, or S-video at INPUT 4 from devices such as VCRs, laser disk players, or

DVD players. At compatible SMPTE signals (note this module can be moved to

INPUT 5 (below INPUT 1), connect serial digital YCbCr (4:2:2) or

INPUT 6 if desired)..

There are also several optional interfaces available for connecting other sources— these interfaces slide into the remaining unused option slot, and can be done while the projector is running.

NOTES: 1) See Section 6, Specifications for details regarding compatible inputs. 2) Use high quality shielded cables only for all connections. 3) The Dual SD/HD-SDI module shown is standard on the Roadster S+, optional for the Mirage S+ series.

RGB Signals '

Figure 2.24. Input Panel

INPUT 1consists of 5 BNCs (connectors) for linking to a variety of RGB sources such

as a PC, Mac, DEC, Sun, SGI, and others. This projector supports multiple sync types with RGB signals: sync-on-green, composite sync, and separate H & V syncs.

NOTE: Depending on your source, you may need a custom adapter cable with BNC connectors at the projector end and a different type of connector at the other (such as a 15-pin “D” connector for some computer sources). Contact your dealer for details.

Connect the outputs to the

SYNC BNC input(s) first. Then connect the red, green, and blue source

RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses

sync-on-green, only the red, green, and blue connections are required. If the source provides a composite sync output, connect it to the

SYNC input labeled HOR/COMP. If

the source provides separate horizontal and vertical sync outputs, connect horizontal sync to the labeled

Figure 2.27. Connecting Composite Video

Christie’s Dual SD/HD-SDI input module is standard with the Roadster S+ and factory-installed in

INPUT 5 or INPUT 6. The module’s loop-through capability

enables incoming serial digital data to be tiled across multiple screens, creating vast “mega resolution” displays. Alternatively, the multiple outputs can be overlapped for extra-bright displays, or simply distributed to additional projectors for multiple screens of the same image.

Other Optional Inputs '

The module accepts one or two independent standard- or high-definition serial digital inputs, decodes them for processing in the main electronics of the projector, and outputs 10-bit YCbCr 4:2:2 video. Either input can be set as the active primary or secondary part of a Picture-in-Picture display, and either input can be looped through to one (or both) of the module’s BNC outputs.

NOTE: Selection of these inputs is described in 3.3, Using the Keypads.

Connect a compatible SMPTE 292M or SMPTE 259M-C source(s) to one or both of the inputs located on the left side of the module. The module will automatically detect the standard at each input and configure itself accordingly for correct termination of the signal. The module also detects and supports dua l link 292M for SMPTE 372M video standards. For full details, consult the Dual SD/HD-SDI manual.

Optional modules allow you to increase your total number of inputs and/or accommodate different signal types, whether analog or digital. Install in the areas labeled

INPUT 6 or (if available) INPUT 5. Options include:

• RGB 500 Input Module

• RGB 400BA Input Module

• RGB 400 Active Loop Thru Input Module

• Composite/S-Video Input Module

(note: not currently supported)

• PC250 Analog Input Module

• Serial Digital Input Module

• DVI Input Module

• Dual SD/HD-SDI Module

INSTALLATION & SETUP

For even more sources, connect a 3rd-party switcher to the RS232 IN port, or, if RS422-compatible, connect to the RS422 port.

NOTES: 1) Optional digital interfaces cannot be used in a Marquee Case/Power Supply.2) See Appendix F, Optional Input Modules for a brief description of each interface.

2.5 Connecting Communications

Remote Keypads '

Other Controllers '

The most common method of controlling the projector is via one of its keypads. As an alternative, you may wish to communicate using a PC or similar controller. Such a device sends commands and receives feedback via serial links (2 types), Ethernet or GPIO communications to the projector, all described below.

As desired, direct the projector’s IR remote keypad towards the display screen or the projector’s IR sensors. Alternatively, connect the remote keypad by cable to the remote phono jack input at the back of the projector.

RS232 Serial Communications

From most computers, connect a standard RS232 serial communication cable between the computer and the projector serial port labeled

RS232 IN—this 9-pin

connector is located on the input panel at the rear of the projector (Figure 2.28). In the Communications menu, set the projector’s baud rate (default = 115200) to match that of the computer.

2-20

Figure 2.28. RS232 Serial Communications

Changing the baud rate is done in the projector’s Communications submenu. See 3.7, Adjusting System Parameters and Advanced Controls.

RS422 Serial Communications

Some computers can provide RS422 serial communications (often through a plug-in adapter or external converter) rather than the more common RS232 standard. RS422 communication has differential “transmits-and-receives” and is generally better suited for long distances than is RS232 communication. Note that RS422 is not compatible with RS232—connecting a RS232-compatible PC to RS422 can damage the equipment at either end. Consult the documentation provided with your PC if you are unsure.

Roadster / Mirage S+ User’s Manual

INSTALLATION & SETUP

Figure 2.29. RS422 Connection to a Computer

The nine-pin RS422 connector is located at the rear of the projector (Figure 2.29). Use this port for communications to and from an RS422-compatible controller. In the Communications menu, set the baud rate to match that of your RS422 controlling device.

WARNING

Do not use an RS422 port unless you are using

equipment with RS422 capability. The voltage levels of

this signal can damage incompatible equipment.

Ethernet Communications

To add the projector to an existing Ethernet network with other equipment such as controllers and other projectors, connect standard CAT5 Ethernet cable between your Ethernet controller (or hub) and the Ethernet port at the rear of the projector as shown in Figure 2.30.

CONNECTING TO A PC: If you are connecting the Ethernet port directly to a PC

(rather than a network or hub), make sure to use a crossover Ethernet cable. Keep in mind that an Ethernet link cannot be used for downloading a software upgrade to the projector—use RS232.

Roadster / Mirage S+ User’s Manual 2-21

INSTALLATION & SETUP

Figure 2.30. Connecting Ethernet

Upon connection to an Ethernet network, the projector’s factory default IP address of

0.0.0.0 will automatically enable the DHCP function (if available on the network) to assign a new IP address that is valid and unique for that network. Or, if there is no DHCP function available on the network (or if a specific static IP address for the projector is preferred or required), you can set the address in the Ethernet Settings submenu or via an ASCII serial command.

NOTE: Make sure the projector is connected to the network before attempting to change its IP address.

Regardless of how it is assigned, once a projector has a valid and unique address it will respond to commands sent to this address. To determine the projector’s current IP address, consult the Status or Communications menus.

Refer to 3.7, Adjusting System Parameters and Advanced Controls for further information about setting up and using a projector connected via Ethernet.

The GPIO Port

The General Purpose In-Out (GPIO) port enables integration of the projector within an established control system (Figure 2.31). ASCII commands sent via the GPIO link are stored in projector memory, where they can be triggered as a sequence of events in the future. See Appendix E.

2.6 Connecting Multiple Projectors

Serial Links '

You may wish to chain two or more projectors together so that commands and communications to and from a controller are relayed to all projectors. Choose a hardware configuration that best suits your desired communication method.

RS232 NETWORK: To control multiple projectors with a computer/controller having

an RS232 interface, first set all projectors to the same baud rate as the controller, then chain the projectors together by connecting the projector (already connected to the computer/controller) to the

RS232 OUT connector of the first

RS232 IN connector of

the next projector in the chain. Continue connecting projectors in this manner until you’ve reached the last projector in the chain, so that only the last projector has an unused

RS232 OUT port. See Figure 2.32.

Figure 2.32. RS232 Serial Link Loop-Through at First Projector

MIXED NETWORK: To control multiple projectors with a computer/controller having

an RS422 interface, first set them all to the same baud rate as your RS422 controller.

Roadster / Mirage S+ User’s Manual 2-23

INSTALLATION & SETUP

NOTE: You must enable this combination of RS422 and RS232 in the Communications menu. Set the “Network Routing” option to “RS232 and RS422 Joined”. See Section 3 for details.

Then chain the projectors together by connecting an (already connected to the computer/controller through the

RS232 port of the first projec tor

RS422 port) to an RS232

port on the next projector in the chain. Continue connecting projectors in this manner until you’ve reached the last projector in the chain, so that only the last projector has one unused

RS232 port. See Figure 2.33.

Figure 2.33. Mixed Serial Network

Note that communication parameters such as baud rate must be set to match the particular controlling device before connecting as a network—refer to the documentation that came with your controlling device in order to determine the proper baud rate. See 3.7, Adjusting System Parameters and Advanced Controls if you need help changing the projector baud rate. In addition, set the Network Routing to “RS232 and RS422 Joined” if you want to reach all projectors.

Ethernet Networks '

NOTES: 1) To avoid damage, connect only properly wired serial communication cables. See Appendix C for details. 2) It is recommended that each RS232 communication cable be no more than 25 feet in length. Use high quality cables.

ETHERNET NETWORK SETUP: To add one or more projectors to an Ethernet network,

use standard CAT5 cable to connect each projector’s Ethernet port to a hub on to the network. A controller or PC must also be connected to the hub. See Figure 2. 34.
