PLACEMENT CONSIDERATIONS

Room Light

Ideally, the PRO900X should be placed in a low-light environment. Picture quality and the ability to see the projected images are adversely affected by bright-light conditions.

Placement

Your PRO900X is shipped from the factory to provide an image with an 80” width as a ceiling-mounted front projector. To ensure proper placement of the unit or to change the size of the projection image, refer to the “Physical

Setup” section.

Viewing Surface

We recommend a good quality screen having a matte white finish, which measures 80” in width (or more) diagonally.

Contact your local dealer for assistance in purchasing an appropriate screen.

Note: Use of a projection screen designed for a single light source projection system may result in significant side-to-side color distortion.

Note to Installer

The purpose of this installation guide is to provide general guidelines for the proper installation and set up of the

PRO900X. Actual operation of the unit is described in the separately supplied Operating Guide and Warranty.

This guide has been prepared for properly trained installers.

INSTALLATION OVERVIEW

Installer’s Experience Level

The PRO900X is a sophisticated Entertainment

Machine TM . In addition to making the necessary connections, installation will most likely require a series of adjustments to ensure the projected image is not distorted. If these adjustments are not accurate, the operation of the PRO900X could be adversely affected. For this reason, installation and setup should be performed by a qualified service person and should conform to all local codes. The installer must also adhere to the pertinent Articles of the National Electrical Code (NEC), pertinent Regulations of the Federal Communications

Commission (FCC), and all relevant codes of local regulating agencies.

Installation Considerations

Before you install the PRO900X...

Ventilation -- Proper ventilation keeps the

PRO900X running cool. Air circulates through perforations on the sides of the cabinet. Do not block these vents or you will shorten the life of the PRO900X.

Power Cord -- The PRO900X has a three-wire grounding-type plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet.

This is a safety feature. If you are unable to insert the plug into the outlet, contact an electrician to replace the obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.

Power Source -- The PRO900X is designed to operate on normal household current, 120 volt

60 Hertz AC or 230 volt 50/60 Hertz AC. Do not attempt to operate it on DC current.

The PRO900X is configured at the factory for 120 volt, 60

Hz operation. A service adjustment is necessary to permit the unit to operate on 230 volt, 50/60 Hz. See Changing

From 120 VAC To 230 VAC in the Setup and Alignment section for details.

PRODUCT OVERVIEW

The PRO900X HD Projection Display system is a high resolution multiple signal format display monitor. It uses 7” high performance liquid cooled CRTs. Each CRT has a 5” active phosphor area and a 90 degree deflection angle. The

CRTs use high-resolution color corrected multi-layered hybrid lens assemblies.

Horizontal scan frequency is from 15 to 50 KHz. Vertical scan frequency is from 40 to 100 Hz. Video system signal bandwidth is 35 MHz. The projected display diagonal size

(4:3 aspect ratio) is adjustable from 60” to 240”.

Supported signal formats include NTSC (3.58 and 4.43),

PAL (M,N,B, and G), VGA, SVGS, Mac II, and Grand Alliance

HDTV. Signal input options include 5 BNC connectors

(R,G,B,V,H), composite video, S-Video (Y-C), and an RS232 serial data port. The IR control format is addressable (0 -

99) for use with multiple unit installations. Each PRO900X comes with a Universal customer remote control and a service/alignment 5-function MBR3470 remote control.

From the factory, the PRO900X comes aligned for a 80” wide display. The preset projection distance is 96 3/8” and configured for a ceiling mount. You may customize the setup to be floor or ceiling mounted and rear or front projected. Refer to the setup section before attempting an installation.

The convergence system is a digital controlled analog system with 10 signal format preset and 5 customer option memory locations. The preset format memory locations cannot be altered in the field. Each preset format has a custom memory location to store customized setup data.

Each customized setup has a separated memory location for each aspect ratio (4 X 3, letter box, compressed, and

16 X 9). You must set up and converge the system for each aspect ratio that will be used. The five customer memory locations are for signal formats that do not match the ten factory preset signal formats. There is also the option to copy the stored format data from one memory location to another. This allows faster setup when several similar formats are used. Internally generated signal patterns also aid with setup of convergence. The internal pattern generator may sync from the internally preset signal formats or it will sync from an external signal source. This is helpful for on-site full convergence or just a touch up. You must use the customer’s signal source to perform blanking and phase adjustments.

The PRO900X cabinet is comprised of three pieces.

Removal of the case allows full maintenance access to the systems electronic and mechanical assemblies. Front and rear mounted IR detector assemblies allow almost no interference to IR control. There are adjustable (and removable) feet on the bottom of the case.

CABINET REMOVAL

Note the location of the screws which need to be removed to allow access to the components.

Caution:

Disconnect the PRO900X from power before attempting to remove the cabinet.

SETUP REMOTE CONTROL

The PRO900X will be supplied with the MBR3470T and a

Universal customer remote control. For most servicing situations the MBR3470T is required. The MBR3470T has the special functions needed for geometry/convergence adjustments and system setup functions which the Universal customer remote cannot perform.

When using the MBR3470T, keep in mind this is a fivemode remote control. The mode functions at the top,

CABLE, VCR, AUX, and TV are standard MBR programmable functions. The SETUP mode is only for PRO900X setup / convergence use. To use the normal “user menu” (Source,

Setup, or Video) the system must be out of the convergence setup mode. The user menus will indicate the current setting by highlighted text or a bar / number indication in the dialog box at the bottom of the screen. The exception is the Source menu which has the three choices with the current selected source being highlighted and control instructions in the dialog box.

SETUP MODE NOTES AND CAUTIONS

1. When you enter the setup mode, the system is in the

“Geometry Mode” (the shape controls adjust all three colors at the same time). To adjust an individual color

(i.e. Red to adjust SKEW), you must press the “Red

Select” key. This will put the system into the

“Convergence Mode” (the shape controls adjust one color at a time). To return to the Geometry Mode, you must press the “Red Select” key a second time.

2. When you are adjusting all colors (“geometry mode”) the little arrow keys at the bottom are for video phase adjust only. When they are pressed, the remote will switch the geometry control to phase. If the arrow keys have not been touched for a few seconds, the remote will automatically switch back to the geometry control you were last using before using the small arrows.

3. When you are adjusting an individual color (“convergence mode”) the little arrow keys at the bottom are for DC Centering only. When they are pressed, the remote will switch the convergence control to DC

Centering. If the arrow keys have not been touched for a few seconds, the remote will automatically switch back to the convergence control you were last using before using the small arrows.

4. The setup controls, in the on screen display, are usually labeled with Horz/Vert, T/L (top/left), or B/R

(bottom/right) and a number value indicating the current setting.

5. If you want to see what effect the “new setting” compared to the “stored setting” has on the display, press the “ADJ TOGGLE” key on the remote. Adjust toggle will allow you to switch between the two settings before committing to a change.

6. After making your changes and adjustments, be sure you SAVE THE NEW SETTINGS. If a major change has been made, new module, new CRT, or a change in the physical setup, you must re-adjust and store the geometry/setup for each of the formats and aspect ratios being used.

7. To escape from the setup mode, without saving any changes, press the “Quit” key twice.

8. Caution - shut all the PRO900X timers and signal source power conserve features off before starting convergence. If the video signal is lost, you will quit convergence mode with no chance to save your work.

9. To display the Forced Mode Menu press “SETUP” and

“GREEN SELECT”.

10. To display the current sync and video format being used press, “GREEN MUTE”.

11.To see the elapsed time display, press and hold “LIN

C/LI-LIN”, until the regular menu disappears, and then press the “TIMER” or “H-Pulse” key.

12.To set the unit IR Code (for use when multiple units are in the area), press and hold “LIN C/LI-LIN”, until the regular menu disappears, and then press “T/LS”, “T/LS”,

“T/LS”, “T/LS”, and “ADJ TOGGLE”.

13. Copying Formats Procedure

Copy the setup information (Convergence, blanking, phase, chromatics, and aspect ratio) from one defined format to another defined format. Procedure quickly copies unrecognized new formats or existing formats to one of the five available “Customer” defined format spaces. The ten factory format presets cannot be overwritten. To display the Copy Format Menu, press

“R-MUTE”. Use the Left/Right arrows to select the format you want to copy. Use the Up/Down arrows to change the menu option from “Copy From” to “Copy To”.

Use ENTER to initate copying the format to the newly specified customer format (Customer 1, Customer 2, etc.) If a format already exists in the selected Customer format space, it will be overwritten by the new format when ENTER is pressed. QUIT exits the menu without making any changes.

14. To aid with the alignment procedure, it is recommended that you mark the center of the screen and the center of all four sides with masking tape. Use “drafting” type tape that will not leave any marks. This will give you calibration points for convergence and CRT alignments.

SCREEN SIZE SELECTION

Courtesy of Draper Shade & Screen

One of the most important decisions in screen selection is to determine the correct size of screen based upon-

1. The dimensions of the audience area.

2. The projection format, or formats, to be used.

In some situations, these two questions yield the same answer; in others they do not and compromises must be made. Here are the key considerations:

Audience Area-In determining the correct size of screen in relation to the audience area, the goal is to make the size large enough so those in the rear of the audience area can see the subject matter easily, but not so large that those in the front of the audience area have difficulty seeing the full width of the projected image.

Width-The generally accepted guideline in determining the screen width is the Two and Six Rule:

A. Screen width should equal the distance from the screen to the first row of seats, divided by two.

B. Screen width should equal the distance from the screen to the last row of seats, divided by six.

In case of a difference between these two guidelines, the one yielding the larger size should prevail.

Height-As a rule of thumb, the screen height should equal or exceeding the distance from the screen to the last row of seats, divided by eight. Ceiling height and projection format considerations may modify this standard.

Ceiling Height-The bottom of the screen should be approximately

48” above the floor to allow all members of the audience to see the bottom of the projected image.

Projection Format-Once you have determined the correct size of the screen based upon the audience area, that size may be based upon the type, or types, of projection equipment to be used. If the screen will only be used with one type of projector of (overhead projector, CRT video projector, etc.), it is easy to determine the exact screen dimensions based upon the projection format of that projector. Projection formats are expressed in terms of aspect ratio, which is the relationship of the height of the projected image to its width. Aspect ratios of common projection formats are listed below.

If it is necessary to modify the screen dimensions based upon the formats of projectors to be used, it is preferable to hold the screen height constant and increase the screen width as necessary, rather than to hold the width constant and decrease the height.

Projection Formats

Most models of DRAPER screens are offered in both audio visual and 3:4 video formats. Certain models are also offered in HDTV and WideScreen formats. The differences between these formats are stated below.

We are glad to provide any DRAPER screen in the size and projection format of your choice. We can provide any size up to and including the largest published size. If you do not find the size and format you need listed, please call or fax your requirement to us, and we will be delighted to quote.

Audiovisual (or AV) format screens are intended for general use.

They accommodate a variety of projector types and range from square to wide horizontal in aspect ratio.

AV format screens are described in terms of height x width, and are standardly furnished without black borders, although borders are optionally available.

Video format screens, on the other hand, are specifically designed for use with video projectors. Their format is strictly defined as a 3:4 rectangle, and the size is usually described in terms of a nominal diagonal. Conventional models of video format screens are standardly furnished with black borders to frame the image on all four sides, allowing for video projector overscan. Tab

Tensioned electric screens are routinely furnished with black borders at the sides and bottom, although black masking at the top is optionally available.

HDTV format (9 high by 16 wide) is also available for high-definition television projection, Anamorphic Video and Wide sssScreen format (1: 1.85).

How to Calculate a Custom Size

Draper also manufactures custom size screens to meet your specification. Virtually any size within the maximum shown for a given model is available. Please call for pricing on special sizes. If you need to calculate a custom size, these formulas may be useful (D

= exact diagonal; H viewing area height; W = viewing area width):

SETUP AND ALIGNMENT PROCEDURE

PROCEDURE OVERVIEW

There are several situations to consider when performing the setup procedure for the PRO900X System. The setup procedure will vary depending on the required physical and signal configuration.

The simplest setup is that of a “factory configured” projector which will use the preset conditions. Factory configured means it has been aligned for ceiling/front projection and a 80” wide display at a projected distance of 96 3/8”. In this case, using the customer’s signal source, only minor blanking, phase, and convergence touch up is required.

If the display size is changed, to other than 80” width or the unit is to be floor-mounted, completion of the full setup procedure is required.

Setup, after a hardware repair, is the other condition.

Replacement of a CRT usually requires minor alignment steps

(yoke, astigmatator, focus, and re-convergence only for that color). Replacement of modules, in the vertical, horizontal deflection, or convergence systems, usually requires that most all alignment steps are to be performed.

I. INSTALLATION PREREQUISITES

1. Mounting Configuration - Floor or Ceiling.

2. Projection Configuration - Front or Rear.

3. Determine Display Size and Aspect Ratio (Shape).

PHYSICAL SETUP TO THE SCREEN (for all aspect ratios)

1. Set distance “A” according to the selected display width

(* or calculate the distance in inches “A” = 1.179 x width) +2.063

Note: Distance “A” is measured from the cabinet panel front directly below the green CRT lens.

2. Calculate the Display Center “B” from a reference line projected from the bottom of the cabinet. Display

Center “B” = A x 0.3057) + 8.44.

3. Set the projector’s height using measurement “B”. This references the bottom of the cabinet to the display center. When doing a ceiling mount, be sure to allow for the dimensions of the mounting bracket hardware.

4. Ensure that the projector is mounted horizontally centered and perpendicular to the screen.

III. PRELIMINARY ALIGNMENT SETUP

The following procedures are intended for complete

“Geometry/Convergence” setup. Use the customer’s signal for doing phase, and size adjustments. You can use the internal patterns for shape and convergence if the customer signal sources do not have a cross-hatch pattern.

If you are realigning a single CRT, due to replacement, or doing alignment touch up, perform the following steps as needed.

1. Yoke Tilt Alignment

Use a cross-hair or cross-hatch pattern. Monitor only the centermost horizontal line of the pattern to check yoke tilt.

Do not use SW9501, on the 9-1510 module, to disable convergence. The vertical circuit is not disabled, only the horizontal is disabled.

a. Set Horizontal DC centering to “0” (red, green, blue).

b. Set Vertical DC centering:

Floor: Red = -30; Green = -20; Blue = -30.

Ceiling : Red = 30; Green = 20; Blue = 30.

c. In geometry mode and convergence mode (green, red, and blue) set “SKEW” H = 0 and “SKEW” V = 0. d. Adjust the Red, Green, and Blue yokes for no horizontal tilt or twist.

If this test shows a need for astimatator alignment perform steps

“a” - “l” below.

Astigmatator Alignment Procedure a. Set the display/sync mode to Forced Mode 6 (HDTV33) and select a cross-hatch or dot pattern. b. Cut off Red and Blue video or cover the CRT lens assemblies. c. Set Green electrical focus slightly CCW. This is to make a near display center dot dimly haloed with a bright center. The haloed effect will also be visible with the cross-hatch lines. d. Use the astigmatator 4-pole magnet to shape the halo and bright spot as round as possible. e. Use the astigmatator 6-pole magnet, if needed, to help shape the halo and spot round. f. Use the astigmatator 2-pole magnet (refer to the figure at bottom left of this page) to center the bright spot within the halo. You may also use an intersection, of the cross-hatch, to center the bright area within the haloed area. g. Use the main yoke magnets to position the signal raster center to the CRT face center. Refer to figure below.

2. Yoke Ring Magnet and Astigmatator Alignment

Verify Only - This is not a normal field adjustment.

The astigmatator assembly should be mounted 62.5 mm from the video output module (from the front edge of the video output module to the six pole rings). Refer to the figure on page 24.

Astigmatator Alignment Verification Test

Adjust for the best electrical and mechanical focus.

Verify spot alignment by rotating Green electrical focus slightly

CW to CCW. The Dot shape should not tail or flair. The bright area should remain in the center of the haloed area. Refer to the figure below.

P A G E 2 2 h. Verify spot alignment by rotating Green electrical focus slightly

CW to CCW. The Dot shape should not tail or flair. The bright area should remain in the center of the haloed area. i. Repeat steps “c” thru “h” as needed to obtain the smallest and best round Green center dot with no shape flaring. j. Adjust for the best electrical and mechanical focus.

k. Repeat steps “c” - “j” for the Red and Blue displays. l. Exit forced mode 6 and return to normal video. Set

Brightness and Contrast to 50.

Note: The yoke adjustments should not be touched during the remaining setup steps.

3. Ceiling/Front Projection Lens Angle Focus Alignment

If this PRO900X system is equipped with the “lens assembly focus” spring, the following procedure must be completed. This procedure must be completed as part of the system mechanical

SYSTEM ALIGNMENT

focus procedure. See the figure above.

a. Turn on the projector, project a cross-hatch pattern on the screen. Cover up both the Blue and Red lenses. Work only on the Green lens.

b. Tighten all 4 lens mounting screws.

c. Loosen all 4 lens mounting screws 3 full turns.

d. Adjust the mechanical and electrical focus to get the best image possible in the center of the picture.

e. Loosen the lens focus adjustment knob. Fully extend the lens barrel. Adjust mechanical focus while observing the center horizontal line. Adjust until one side (left or right) comes sharpely into focus. Adjust the two screws opposite the side that is in focus (i.e., if the left side of the center horizontal line is in focus, adjust the two screws on the right side of the lens). Turn each screw 1/4 - 1/2 turn at-a-time in the same direction (in or out) while observing the focus of the center horizontal line. If the sharp focus begins to move towards the center of the image, you are going in the wrong dierction (in or out). Adjust in the correct direction until the entire line achieves a uniform soft focus from left to right. You should then be able to adjust the barrel focus to get the center horizontal line sharp all the way across. If not, you can fine adjust with this same procedure.

f. Loosen the lens focus adjustment knob. Fully extend the lens barrel. Adjust mechanical focus while observing the center vertical line. Adjust until one side (top or bottom) comes sharpely into focus. Adjust the two screws opposite the side that is in focus (i.e., if the bottom of the center vertical line is in focus, adjust the two screws on the top of the lens). Turn each screw 1/4 - 1/2 turn at a time in the same direction (in or out) while observing the focus of the center vertical line. If the sharp focus begins to move towards the center of the image, you are going in the wrong dierction (in or out). Adjust in the correct direction until the entire line achieves a uniform soft focus from top to bottom. You should then be able to adjust the barrel focus to get the entire image sharp all the way across (top to bottom and left to right). If not, you can fine adjust with this same procedure.

Note: Throughout this procedure pay no attention to the corners of the image.

g. Adjust the focus mechanically and electrically to get the best overall image.

h. Cover the Green lens and uncover the Red lens.

i. Repeat step “b” - “g” for Red.

j. Cover the Red lens and uncover the Blue lens.

k. Repeat steps “b” - “g” for Blue.

l. Re-install PRO900X top cover. m. Turn off the sync forced mode 9 and return to normal video viewing or sync forced mode 11.

4. Rough Geometry/Convergence Setup of Green

When aligning Green, some controls are enabled in Geometry only.

This is why the alignment starts by using Green in the geometry mode of setup. a. Using the setup remote control, press “SETUP” and “RED”.

This will put the system into the “GEOMETRY MODE”. b. Using the setup remote control press “RED MUTE” and

“BLUE MUTE”. You should see only the Green video.

c. Roughly set up the shape of the Green display using the appropriate Skew, Bow, Key, etc. controls. Adjust size, or phase using the customer’s video signal. Refer to pages 25,

26, and 27 for the convergence remote control and procedure notes.

5. Rough Geometry/Convergence of Red and Blue a. Using the remote control, return to the SETUP Mode and select the internal cross-hatch pattern. b. Press “RED” and mute the Blue video. c. Using the “Point Angle” adjustment screws, align the Red center point horizontally with the Green center point. d. Using DC vertical center, align the horizontal center line of the Red pattern to the horizontal center line of the Green pattern. e. Adjust Red “Size” and “Lin T/B - L/R “ to roughly match the Green pattern size. Refer to pages 25, 26, and 27.

f. Roughly set up the shape of the Red display using the appropriate Skew, Bow, Key, etc. controls. Refer to pages 25, 26, and 27. g. Press “BLUE” and mute the Red video. h. Using the “Point Angle” adjustment screws, align the Red center point horizontally with the Green center point. i. Using DC vertical center, align the horizontal center line of the Blue pattern to the horizontal center line of the Green pattern. j. Adjust Blue “Size” and “Lin T/B - L/R “ to roughly match the Green pattern size. Refer to pages 25, 26, and 27.

k. Roughly set up the shape of the blue display using the appropriate Skew, Bow, Key, etc. controls. Refer to pages 25,

26, and 27. l. Press “QUIT” and “ADJ TOGGLE” to store the adjustments.

IV. Final Detailed Geometry/Convergence Setup

Use the video patterns generated by the customer’s signal source for final alignment. If this is not possible, use the internal cross hatch pattern only to do the geometry and convergence. The customer’s signal must be used for blanking, size, centering and phase.

1. Green Geometry Setup a. Return to the geometry and convergence modes and set up the Green display with precision. Each step should be done by measuring the display and not guess work. b. Now store the Green setup.

2. Red to Green Convergence Setup a. Return to the convergence mode and set up the red display with precision. Converge the Red display to the Green display using all necessary controls. b. Now store the Red setup.

3. Blue to Green Convergence Setup a. Return to the convergence mode and set up the Blue display with precision. Converge the Red display to the Green display using all necessary controls. b. Now store the Blue setup.

4. Red to Green to Blue Convergence Setup a. Return to the convergence mode and set up the Red and

Blue display with precision. Converge the Red display to the

Green display using all necessary controls. b. Now store the completed setup.

5. Video Blanking Setup Using the Customer’s Signal a. Access the Blanking/Phase feature of the setup menu. b. Select the TOP/LEFT BLANKING feature.

c. Using the small arrows adjust the top and left edges

(increasing the setting number) until the edge begins to crop or frame the video. Decease the number until the cropping just stops. Now decease the number value two more. d. Select the BOTTOM/RIGHT BLANKING feature, repeat step c. e. Press ADJ TOGGLE and save the settings.

V. Geometry/Convergence of Other Aspect Ratios

1. Geometry/Convergence setup must be accomplished for each required aspect ratio of each signal format used (Video,

S-Video, RGB VGA400, VGA480, SVGA, etc.).

2. Each of the ten standard signal format memory “custom” loca tions also has a “custom” location for each of associated aspect ratios.

3. The five “customer” format memory locations also store the aspect ratio information separately.

4. RGB sources use the 4 x 3, letter box, or 16 x 9 aspect ratios.

5. Video and S-Video sources use the 4 x 3, letter box,

Compressed, and 16 x 9 aspect ratios.
