Safety Warnings

All the safety warning in this manual are in bold italic type and can be identified by the symbol shown on the left.

A list containing all the warnings is given below. It is recommended that time is taken to study these before installing or operating the projector.

The projector should always be lifted using the handrail. Do not attempt to lift the projector by holding the covers or the lens.

The customer should never attempt to disassemble the lamp from its housing or to dispose of it other than by returning it to Digital Projection.

The condenser is precisely aligned in the factory. If it is moved there could be a reduction in light output and image display quality.

Do not move or tamper with any seals or ducting panels on the projector or the air flow could be disrupted and cause the projector to overheat. Always keep the air inlets and outlets clear of any obstruction.

High Voltage, Danger of Death - the arc lamp power supply has a 30kV strike pulse mechanism, which is active during lamp switch-on.

The projector should never, under any circumstances, be operated upside with the lamp pointing upwards (i.e. with the right hand side facing downwards).

To avoid possible damage to the prism, lens and lent mount, a lens adapter must by used if using POWER gv lenses on an LIGHTNING sx projector.

Never mount the projector near air conditioning or heating ducts, electrical wiring or any materials which could be affected by the projector's operational heat i.e. polystyrene ceiling tiles etc. The projector should never, under any circumstances, be operated with the lamp pointing upwards (i.e. with the right hand side of the projector facing downwards).

At least 4 people are required for safe movement of the projector. The projector is designed to be lifted using the handrail at the base. Do not attempt to lift the projector by holding the front, the side covers or the lens.

Care should be taken when removing or attaching the projector feet to ensure that the projector does not rest on its feet at an angle.

Never operate the projector with the cover removed and always switch off the mains supply and disconnect the plug before removing the cover.

Never look into the lamp housing or the lens, or attempt to remove the lamp from its housing when the projector is on.

OTHER IMPORTANT SAFETY CONSIDERATIONS

In order to ensure that correct internal airflows are maintained, and that the projector complies with Electro-Magnetic Compatibility requirements, it should always be operated with all of it's covers in place.

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.

The projector must always be mounted 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. The air exit duct at the right-hand side of the projector can become hot during operation and should not be touched by the operator. Heat sensitive materials should not be placed in the path of the exhausted air.

Remote Receiver

The optional remote receiver acts as a relay between the remote control and the projector and is useful for installations where the Infra Red signal from the remote cannot reach the sensors on the projector.

The Infra Red signals from the remote control are picked up by the IR receiver on the front of the remote receiver and are relayed to the projector via the 15 way high density 'D' style connector on the underside of the unit.

The remote receiver also allows direct cabling (hard wiring) of the remote control unit via a 4 way 'LEMO' connector. When used in this way, the remote control does not require batteries and the IR receiver on the remote receiver is disabled.

Hard wiring has the advantage of allowing control of the projector from a greater distance: The cable from the remote control to the remote receiver can be up to 10m (33ft) in length and the cable connecting the remote receiver to the projector can be up to 60m (200ft) long.

When hard wiring, the remote control unit must be connected to the remote receiver before the remote receiver is connected to the projector. If the connections are not made in this order the remote receiver fuse will trip and the remote receiver will have to be disconnected for approximately one minute before reconnecting in the correct manner.

For further information on remote receiver wiring, see Cables and Connections, D—18.

Hard Wired Remote Adapter

The hard wired remote adapter consist of two cables which connect together to form a direct (hard wired) link between the remote control unit and the projector.

The longer of the two cables has with a 3.5mm stereo jack plug at one end which connects into the top of the remote control unit.

The 3.5mm stereo jack plug has a long outer shell - some of which may be visible when the plug is seated correctly in the Remote Control Unit. To avoid damage, do not attempt to push the plug further into the Remote Control Unit.

The shorter cable has a 15-pin ‘D’ type connector which connects to the ‘Ext Remote’ input on the back of the projector. The two cables then connect together using a 3-pole audio/video connector and are secured by a latch to prevent accidental disengagement

The remote control unit must be connected to the remote adapter before the remote adapter is connected to the projector. If the connections are not made in this order the remote adapter fuse will trip and the remote adapter will have to be disconnected for approximately one minute before reconnecting in the correct manner.

As with hard wiring via the remote receiver, the remote control does not require batteries when used in this manner. The remote adapter also allows control of the projector from a greater distance than via the remote receiver - using standard ‘XLR’ cable assemblies the user can extend the length of cable up to a maximum of 100m (330ft).

For further information on the hard wire remote adapter wiring, see Cables and Connections, D—20.

LED Indicators

There are 3 Light Emitting Diodes on the front of the projector which indicate the status of the projector. The top red LED is used to indicate that power is applied to the projector and that it is turned on. The middle green LED indicates normal operation and flashes when the projector is receiving a signal from the remote control unit. The bottom red LED indicates that the lamp has failed or is switched off. For further information see System Operation, C—6.

Arc Lamp

The projector uses a specialised, high pressure xenon arc lamp designed to operate in conjunction with Digital Projection's optical condenser system and specialised power supply unit. The lamp achieves maximum brightness within 1 minute of strike and is designed for an operating life of greater than 750 hours.

The operator is advised to switch off the lamp using the 'LAMP OFF' button on the remote control, and allow the cooling system to run on for ten minutes before switching off the mains supply.

The lamp is contained in a special safety housing to dissipate heat and to make changing the lamp as easy as possible (see Fault Finding and Maintenance, E—6).

The customer should never attempt to disassemble the lamp from its housing or to dispose of it other than by returning it to Digital Projection.

Lenses

Four zoom lenses have been developed specifically for the LIGHTNING sx range of projectors; zoom ratios 1.5 - 2.0:1, 2.0 - 2.5, 2.5 - 4.0:1 and 4.0 - 7.0:1.

Using a lens adapter, the lenses developed for the POWER gv series may also be used, albeit with modified throw ratios and limited lens shift capabilities.

Motorised Lens Mount

The LIGHTNING sx range of projectors incorporate a motorised lens mount. This mounting allows you to control the zoom/focus via the remote control.

As the lens mount attaches to the lens, the mounting mechanism must be released before a lens can be fitted or removed. To release the lens mount turn the mounting lever anti-clockwise (upwards). After fitting a lens the lever should be turned clockwise to engage the mechanism.

When engaging the lens mount, the lens may have to be rotated slightly in order for the lens mounting to connect correctly.

Optics

The lamp faces onto a 'cold mirror' which directs the light beam into a condenser. A prism then splits the concentrated beam from the condenser into red, green and blue light using dichroic filters and directs the light onto separate DMDs™. The images produced by the three DMDs™ are then combined by the prism to form a full colour image and directed into the lens for projection.

The condenser is precisely aligned in the factory. If it is moved there could be a reduction in light output and image display quality.

Electronics

The main electronic components of the projector are the Analogue Input Board, Digital Processing Card, Formatter Card and the three Display Boards (each of which contains a Digital Micromirror Device™).

The Analogue Input Board, situated at the rear of the projector, converts analogue inputs to digital signals and routes them to the digital processing card.

The Digital Processing Card stores the channel configurations and any on screen adjustments such as brightness, contrast etc. These settings are applied to the incoming signal for transfer to the Formatter Card.

The Formatter Card translates the digital signal into a format that the Digital Micromirror Devices™ can read.

Analogue Input Board

The Analogue Input Board located at the rear of the projector provides all the required connections for video, computer and remote control inputs. The input board is split in three main sections - Source, Digital and Control (see opposite).

Digital Micromirror Devicesª

A Digital Micromirror Device™ (DMD™) is a digital light modulator fabricated from moving aluminum mirrors. Each mirror, which acts as a pixel, is suspended between two posts by a thin torsion hinge and can be tilted to the left to produce a bright pixel or to the right for a dark pixel.

There are three DMDs™ in the projector, one for each of the primary colours, each containing 1,310,720 mirrors arranged in a 1280 x 1024 array.

Cooling System

During normal operation considerable heat is generated inside the projector, therefore, an air cooling system is provided. This consists of a powerful fan which draws cool air through specially designed air ducts within the case to distribute it over the lamp and other components. The cooling system provides maximum cooling whilst minimising noise output.

Power supplies

The General Power Supply provides a range of low voltage rails to the electronics. The Xenon Arc Lamp has a separate high current power supply.

High Voltage, Danger of Death - the arc lamp power supply has a 30kV strike pulse mechanism, which is active during lamp switch-on.

Remote Receiver

The optional remote receiver is used to pick-up infra-red signals from the remote control unit and relay them to the projector.and also provides a 'hard wire' interface between the remote control and the projector.

The remote receiver is a small 75mm x 100mm x 25mm (3" x 4" x 1") matt black box with mounting lugs on each end and an infra red sensor on the front. On the underside there are 2 connection points:- a 15 way high density 'D' style connector for the projector and a 4 way 'LEMO' connector for the remote control (refer to A—7 and D—18 for more information).

Hard Wired Remote Adapter

The hard wired remote adapter provides direct connection between the remote control and the projector without the need for the remote receiver as an interface. The remote adapter is provided as standard with LIGHTNING display projectors.

The adapter consists of two cables - a 15-pin high-density ‘D’ type plug to ‘XLR’ socket with integral decoder circuit and an ‘XLR’ plug to 3.5mm stereo jack plug. This cable assembly enables the user to extend the remote adapter using a standard audio/video cable (refer to A—8 and D—20 for more information).

Integrated Keypad

An integrated keypad is provided on the rear of the projector to allow the projector to be controlled without the remote control. The operation of this keypad is identical to that of the remote control (see System Operation, C—1 for further details).

Remote Control

All the functions of the LIGHTNING display are controlled using the remote control or the integrated keypad on the rear of the projector. The remote control can be connected to the projector via the remote receiver or hard wired remote adapter. This connection simultaneously powers the control unit, illuminates the remote controls back panel and relays commands back to the projector.

To allow the operator more flexibility the remote control can be operated by four AAA batteries, producing infra-red signals which are detected by sensors located at the front and rear of the projector. The Remote Control unit is designed to transmit command signals to the projector from a maximum distance of 80m (266ft).

Very bright fluorescent lighting or Infra Red translation systems may saturate the projectors Infra Red receivers rendering remote control inoperative.

Palm Pilot Control Utility

The Palm Pilot Control Utility has been designed to allow extensive operational control of the projector without using the on-screen menu system. The control program is designed to operate with the computer port of any LIGHTNING display projector and is capable of controlling multiple (daisy-chained) projectors.

For information on operating the Palm Pilot Control Program refer to System Operation, C—55.

There are other programs available for the Palm Pilot platform which provide for full set-up and design, contact your Digital Projection dealer for further details.

Page 30

This installation section explains how to install the projector for optimum results. To do this, it is necessary to determine the following:

1. The type of screen and whether front or rear projection is to be used.

2. The projector location and therefore the type of lens to be used.

3. The method of mounting for the projector.

4. The type of input source to be used with the projector.

Screen Requirements

As virtually all commercially available screens will give a pleasing image you should choose according to your individual requirements. However, to achieve optimum results we recommend a low gain (1.2 - 1.3), non-perforated screen for front projection, this will keep hot spotting and light loss to a minimum whilst providing wide viewing angles.

Regardless of the type of screen used, it is important that your screen is of sufficient height to display the images at the aspect ratios intended to be used. Use the following tables to check that you are able to display the full image on your screen. If you have insufficient height, you will have to reduce the overall image size in order to display the full image on your screen.

Screen Height (metres) Needed to Display Full Image with Aspect Ratio:

Page 31

For optimum viewing, the screen should be a flat surface perpendicular to the floor. The bottom of the screen should be 1.2m (4 feet) above the floor and the front row of the audience should not have to look up more than 30° to see the top of the screen (see opposite).

The distance between the front row of the audience and the screen should be at least twice the screen height and the distance between the back row and the screen should be a maximum of 8 times the screen height. The screen viewing area should be within a 60° range from the face of the screen.

If you intend to use a rear projection screen you must ensure you have sufficient distance behind the screen for the projector to be correctly located (see B—4). Rear projection has the advantage that the projector cannot be seen and higher ambient light levels can be tolerated. Although the image can be flipped to rear projection using the Image Mode Menu (see system operation, C—28) and displayed without the need for extra mirrors or equipment, it makes the installation more complicated and advice should be sought from your local dealer before attempting an installation in this way.

Positioning the Projector

Correct positioning of the projector is essential to achieve the best results. Before deciding on the final location of the projector please ensure you read the following information very carefully.

The projector must be situated in a clean, dry environment and away from direct sunlight or heat. Make sure you locate the projector so that the air inlets and outlets for the cooling system are not obstructed.

The projector should never, under any circumstances, be operated with the lamp pointing upwards (i.e. with the right hand side facing downwards).

PROJECTOR HEIGHT

The default height for positioning the projector is at the centre of your screen. However, you can set the projector above or below the centre and adjust the image using the ‘Lens Shift’ (Rising/Falling Front) facility to maintain a geometrically correct image. Typically, the projector can be located up to the top or bottom of the screen without geometrical distortions, but please refer to the lens data sheets for information on the maximum rising/falling front correction available for a particular lens. In some cases the projector may also be tilted without introducing observable distortions.

HORIZONTAL POSITION

As with vertical positioning, the default horizontal position of the projector is at the centre of the screen. However, the projector can be mounted up to one quarter screen width left or right of image centre and the ‘Horizontal Lens Shift’ function used to centre the image on screen without geometric distortion.

Vertical Lens Shift and Horizontal Lens Shift can be used in combination, however the extent of their individual ranges will be reduced according to the amount of shift used i.e. Vertical Lens Shift is maximised when Horizontal Lens Shift is centred and vice versa.

THROW DISTANCE - FIXED RATIO LENSES

It is important to position the projector at the right distance from the screen. This 'Throw Distance' is defined as the distance from the screen to the front of the projector case. It is calculated by taking into account your screen width, the type of lens used, and the aspect ratio you intend to display.

If you intend to display images with different aspect ratios, it is recommended that you position the projector at a distance from the screen which will allow you to project images at the maximum fractional aspect ratio (16:9 = 1.78, 5:4 = 1.25), i.e. the image with the largest width. Failure to do so could result in smaller fractional aspect ratio images exceeding the feight and/or width of your screen.

THROW DISTANCE - ZOOM LENSES

When using a zoom lens, exact positioning of the projector less important because the image size can be adjusted. However, the projector must be located within the Throw Distance range imposed by the minimum and maximum lens ratios.

If you intend to display images with different aspect ratios, it is recommended that you define your own Throw Distance range. To define the minimum screen distance, use the lowest lens throw ratio associated with the smallest fractional aspect ratio used. To define the maximum screen distance, use the largest lens throw ratio associated with the largest fractional aspect ratio used.

CALCULATING THE THROW DISTANCE

To calculate the distance between the screen and the front of the projector case use the equation given below. The tables overleaf give the actual lens throw ratios (with tolerances) and lens extensions. Perform the calculation for each end of the zoom range to define the throw distance range. The tables also give the tolerance in throw ratio if more accurate calculations are required.

Distance Required = (Screen Width x Actual Lens Throw Ratio) + Offset

The lenses developed for the POWER gv series may be used with a LIGHTNING sx projector, albeit with limited lens shift capabilities and the use of an adapter. It should be noted that the throw ratios of the POWER gv lenses, when used on a LIGHTNING sx projector are modified and the following table should be used to cal- culate the screen distances required.

Mounting the Projector

Now that you know the distance from the screen that the projector must be located you can decide on which type of mounting will best suit your requirements. The easiest method of mounting is to rest the projector on a desk or table directly in front of the display screen. If you intend to use this method, make sure that the desk or table is strong enough to support the projector's weight safely.

MOUNTING FEET

There are four mounting points located on the underside of the projector for the attachment of the mounting feet. Each foot is screwed into the mounting points and tightened using a spanner on the flats of the foot shaft.

The projector can be levelled using the black adjustment rings on each foot which allow 25mm (1 inch) of movement. The rubber foot base incorporates a ball socket connector which will form to an uneven surface to assist in mounting.

Although the adjustment rings on the projector feet will allow the slight raising or lowering of the front of the projector, it is recommended that projector is made level and the lens shift feature is used to perform this function.

Care should be taken when removing or attaching the projector feet to ensure that the projector does not rest on its feet at an angle.

External Cable Routing

In order to help prevent cross coupling, it is good working practice to avoid running signal cables and mains cables closely bundled together over long distances.

Where this advice is not observed, the user may experience poor picture quality, inexplicable and spurious operation, or, in extreme cases, cause hardware damage.

First of all, connect the video signal input source to the Analogue Input Board at the back of the projector (refer to Signal Sources for details on different sources and how to connect them). Then plug the projector into the mains supply and switch it on (using the on/off switch at the back of the projector). Switch on the video source. The projector will select the first valid signal as defined in the User Preferences and display the image using the Factory Default parameters. The quality of the image can be adjusted using the remote buttons. Refer to Adjusting the displayed Image (System Operation, C—44) for further information.

Never operate the projector with the cover removed and always switch off the mains supply and disconnect the plug before removing the cover.

If there is no image on the screen, check that the video source is operating and connected to the correct input, e.g. if it is a one lead composite source, then it should be plugged into the Composite/G input.

After initial power-up, you can define how the projector will subsequently start-up by using the User Preferences Menu (see System Operation, C—29).

Signal Sources

The projector accepts composite, S-Video, Y Pr Pb and RGB input signals. These signals constitute most of the video and computer formats available. The analogue input board at the back of the projector provides three rows of 5 input ports. Each row is configured to accept any of the given signal types by using the appropriate port combination. The provision of three rows (inputs 1, 2 and 3) allows three signal types to be connected at any one time.

The correct port combination must be used in order to display the image.

Turning On the Lamp

The lamp should light up within 25 seconds of the projector being turned on. If it has not lit, the bottom red LED at the front of the case will glow constantly and the projector should be turned off and back on again.

Never look into the lamp housing or the lens, or attempt to remove the lamp from its housing when the projector is on.

Picture Display

The picture display can be controlled using the PIC MUTE button on the remote control. When muted the screen goes blank (with the shutter option included, PIC MUTE will provide additional blackout by removing any stray light that may fall onto the screen). Changing the lamp power when the picture is muted will cause the image to be displayed.

When unmuted the video image is displayed on screen and the lamp is set to either HIGH or LOW depending on the last selection made with the lamp power buttons.

The Picture Display can be set in the User Preferences menu for the next time the projector is switched on (see System Operation, C—29).

IMAGE CONTROL

The image parameters determine how a picture looks on screen and are adjusted by using the remote control or the on-screen Modify menu. Adjustable parameters include Brightness, Contrast, Sharpness, Saturation, Hue, Size, Position, Pixel number, Pixel phase and Colour Temperature.

To adjust a parameter using the remote control, first press the appropriate command button then use the ñ , ð buttons to increase and the ò , ï buttons to decrease the value (see System Operation, C—1). If the cursor buttons are not pressed within ten seconds, the function will be deactivated. If a second function is selected before the ten seconds have elapsed, the new function will be applied instead.

The Image Parameter controls on the remote can be used when in the Menu system providing that no data fields are being edited.

The adjusted parameter settings for an input device can be saved to a 'channel'. A channel setting also stores the input source address (see storing system configurations, B—15, for more information). This allows you to use the input device at a later date without having to reconfigure the parameters to achieve the desired image. The channel is selected in the Channel Set-up menu or by using the remote. The source image is then displayed on screen.

LENS CONTROL

Projectors fitted with a motorised lens mount have additional picture control features available via the remote control in the form of Focus, Zoom and Lens Shift. These features are operated via the LENS button (see System Operation, C—4) and allow the user to either adjust the image Focus and/or adjust the horizontal and vertical positioning of the displayed image relative to the projector.

ON SCREEN DISPLAY (OSD)

The On Screen Display (OSD) displays the system menus and messages. The OSD will come on automatically at power-up if it is preset in User Preferences Menu. Alternatively it can be activated by the OSD ON remote control button.

MENU SYSTEM

The main menu provides access to dialogue boxes which allow you to control the projector and to view system settings. If the OSD is set or switched to 'OFF' the menu system and messages will not be displayed on screen.

Storing System Configurations

A Channel is a 'store' containing all of the parameters associated with an input and the image it displays. The projector has 63 available channels.

In addition to the channels there are three further 'stores'. They are the Previous Store, Revised Store and Factory Pre-set. These three stores are accessed directly from the remote using the PREV (previous store), REV (revised store) and >.< (factory pre-set) buttons.

When a channel has just been selected or the factory pre-set is being used, the parameters are held in the previous store. If any changes are then made to the channel or the pre-set, they are held in the revised store.

Modifications made to the image parameters will be applied to the revised store regardless of whether the previous or revised image is being displayed.

At any point PREV and REV can be pressed to compare the original image with the revised image. Any final changes can be saved by pressing SAVE on the remote which will transfer the contents of the Revised store to the last channel selected.

Pressing SAVE will save any changes made regardless of which view is being displayed

To clear changes held in the Revised store re-select the original channel using the numeric keypad on the remote control.

The factory pre-set contains configuration parameters which cannot be altered, however changes can be made and stored in a new channel using the Channel Set-up menu. There is a pre-set for a computer input and one for a video input. The pre-set will produce an image but not necessarily of the ultimate quality. The quality can be improved using the Modify Command. The factory pre-set channel number is 0 (zero).

To find out which channel is currently being used, press MENU and select Channel Set-up. The current channel will be highlighted in the channel list.

Both the remote control unit and the integrated keypad on the rear of the projector can be used to select channels, adjust parameters and navigate through the menu systems.

Most of the control functions have an icon and a scalar bar which are displayed on screen when the function is activated.

When making adjustments to the image settings, always make sure the On Screen Display is on. You can use the On Screen Display whilst showing an image to see the affects of any changes made.

As projector operation will frequently take place in a darkened room, the remote control has a built in back-light which illuminates the control panel. When the remote control is directly connected to the projector (either via the Remote Receiver or using the Hard Wire Remote Adapter) this light will be constantly illuminated allowing you to locate the buttons required. When battery operated, pressing 'LIGHT' on the remote control will illuminate the panel and activate a timer. This timer will automatically turn the back-light off after 10 seconds and is reset every time you press a button. Therefore the back-light will stay on for 10 seconds after the last operation on the remote.

BUTTON FUNCTION / OPERATION

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------A When using multiple projectors, it may be necessary to control all

projectors collectively and individually. This is achieved by allocating an address to each projector (using the menu system C—35). All projectors will respond to the remote control when the address is set to 0. To address an individual projector, press A twice followed by the projector's address.-

PAN, ZOOM Future features, these buttons currently do not have any effect on RGB, UNDO projector operation.

There are 3 Light Emitting Diodes (top - red, middle - green, bottom - red) at the front of the case which indicate the status of the projector.

The top red LED, when on constantly, indicates that power is applied to the projector and that it is turned on.

The green LED, when on constantly, indicates the projector is operating normally and the lamp is lit. When flashing, the green LED shows that a valid remote control signal is being received. If the green LED is not illuminated, it indicates a fault.

When the bottom red LED is illuminated, it indicates that the lamp is switched off or has failed to strike. This could be due to lamp failure or the safety interlock switch circuit detecting a fault condition.

The Channel Set-up function allows you to create NEW channel configurations and SELECT, VIEW, COPY, MODIFY or DELETE current channels. Creating or editing channel parameters does not require the input source to be present, however for the best results it is advisable to make adjustments while viewing the image on screen.

Before you can adjust a channel you first have to select it. The only exception is when using the Copy command, when you can copy a highlighted channel configuration to another channel.

The parameters which can be accessed and edited in the Channel Set-up menu are: channel name; input number; external switcher input number; source format Y Pr Pb / RGB; video standard PAL / NTSC / SECAM; computer selection; pixel resolution; pixel phase; image size and position; aspect ratio; colour temperature; signal sync source.

In addition each channel will store the selected settings for brightness, contrast, saturation, hue and sharpness where applicable. These parameters are accessed via the remote control. If they are saved using the SAVE button the settings for that particular channel will be stored in memory.

There are two factory presets for new channels - one for video input and one for computer input and both presets use the settings defined in the User Preferences screen.

For a computer input, the size, position, pixel and phase will be determined by the choice of computer card and the mode selected by the input signal.

The Channel Set-up screen which is accessed from the Main Menu is shown opposite. The screen has a row of options across the bottom and is split into 5 columns- Chan, Name , IP, ADR and Type.

Chan: This is the channel number entered on the remote control keypad to select an input. The channels are listed in numerical order and are scrollable.

Name: A name of up to 14 characters in length can be entered to describe each channel.

IP: Specifies which input connection on the rear of the projector (1, 2 or 3) will be used for a particular channel.

ADR: The switcher input address. If a number is preset here, the projector will command a video switcher to select that input via the RS232 serial control cable.

Type: Denotes the type of input source for each channel. Examples of a video input include PAL, NTSC and SECAM, While computer inputs could be VIDEO7, TSENG, MATRX, etc. (for further information see B—17, Signal Sources ).

SELECT Command

Channel selection can be made in two ways, by simply keying in the channel number on the remote control or by selection in the Channel Set-up screen. Using the remote control is quicker if you know the channel number required, but if you don't, the Channel Set-up screen will remind you.

To select a channel using the On Screen Display, first choose Channel Set-up from the the Main Menu and locate the cursor over the desired channel using the

ñ and ò buttons. Highlight 'SELECT' from the options at the bottom of the screen

using the ï and ð buttons and press 'Enter' to display the selected channel.

If a blank channel is selected, the image display will turn black and a message box will be overlaid stating- "Channel XX not configured"

If a valid channel is selected but a source is not detected at the input, the screen will go black until the signal is connected. A message box will be overlaid stating"Source is not Present".

If a valid channel is selected but the detected source is different from that expected, a message box will be overlaid stating- "Source is not the expected configuration".

The system will do its best to display the image using the parameters of the selected channel.

If a channel configured for a computer is selected and the projector does not identify a computer card mode which matches the incoming signal, the screen will display an image using the system default parameters. These parameters, such as size and position, are stored in the system memory. An on-screen message also appears stating- "New mode will be lost if not saved or if channel is changed". The display will then have to be adjusted manually to give an optimum image (Refer to Storing System Configurations, B—15 for further details).

DELETE Command

It is possible to delete a single mode contained within a Computer Card or all the modes contained within a card effectively deleting the complete card. Deletion of a Computer Card takes place in the Add Computer screen as the most likely reason for deleting a card is that there is insufficient memory available to add a new card.

Only Computer Cards you have created are valid for deletion, factory supplied cards cannot be deleted. "NEW" is also an invalid option as it represents a card which has still to be created, therefore cannot be deleted. If you try to delete an invalid card a message box will appear advising you that the card you have selected cannot be deleted.

Whether deleting all modes or a single mode from a Computer Card the first step is to select the card from the fly-out menu in the Add Computer screen using the remote control.

The function buttons, located at the bottom of the remote control, allow you to adjust (where applicable) the brightness, contrast, sharpness, saturation, hue, position, size, pixel resolution, pixel phase and colour temperature of the channel currently being displayed. If a motorised lens mount is fitted to the projector the focus and horizontal/vertical position of the displayed image may also be adjusted using the ‘LENS’ button.

Although it is not a necessity, it is recommended that the On Screen Display should be ON before adjusting any of the channel parameters as you can then be sure which function (if any) has been activated.

When the OSD in ON, pressing a function button will bring up it's icon and a scalar bar indicating the current setting. This value can then be adjusted using the cursor keys. The current channel is displayed in the background so that you can see the changes in the image as it is adjusted. All of the functions operate a 'Hold Live' system which deactivates the function after 5 seconds if no further buttons are pressed (or 5 seconds after the last adjustment was made).

The cursor keys are repeat action buttons and will keep changing a setting until released or the parameter limits have been reached.

After making your adjustments to the channel image you can toggle between the original and revised parameter settings using the 'PREV' (previous) and 'REV' (revised) buttons on the remote control. To save your new settings press the 'SAVE' button, the save icon will appear for 5 seconds along with a message stating, "Channel XX updated successfully" (where XX is the channel number currently being displayed).

As factory preset channels are mapped to specific inputs it is not possible to change a factory preset channels input. Should you wish to use a modified version of these channels using a different physical input the modifications must be saved a new channel using Channel Set Up.

Adjusts the horizontal and vertical position of the displayed image relative to the projector. To select Lens Shift press LENS until the Lens Shift dialogue box appears on the screen. The horizontal shift can then be adjusted using the ï and ð cursors. The vertical shift (rising/falling front) is adjusted by using the ñ and ò cursors.

Vertical and horizontal shift can be used in combination, however the extent of their individual ranges will be reduced depending on the amount of shift used i.e. vertical shift is maximised when horizontal shift is centred and vice versa. When the extent of the range reaches its limit, it is possible that there will be a slight distortion of the lens position which may result in additional flare. If this position is reached, reduce the lens shift until the distortion is removed.

ZOOM

The LENS button on the remote control also has a Zoom option.

Multiple projectors are used to produce a brighter image, to join up two or more images or to display two or more images side by side.

When using multiple projectors it may be necessary to control all projectors at once, or to operate an individual projector. This is achieved through the use of the Infrared remote control or a computer.

Each projector has its own unique address which is set using the remote control or a computer (see Set Projector Address, C—35 & Computer Control, opposite). The remote control can operate up to 32 projectors and a computer is capable of operating up to 127.

The 'A' button on the remote control is used to program the remote control unit to send a command to all operating projectors, or to an individual projector, see the examples below.

To activate only projector #1:

1. Press 'A' twice.

2. Press '1'.

3. Use control buttons to operate projector #1.

To address all of the projectors:

1. Press 'A' twice.

2. Press '0' (zero is the global address).

3. Use control buttons to operate all projectors.

You must press the 'A' button twice within three seconds in order for the function to be recognised and the function will be automatically de-selected if you do not issue any commands within 10 seconds.

All of the remote commands, apart from 'A', can be global or individual. If you use the remote for an individual projector, you will need to make sure that only that projector receives the command.

To control the projector by computer, it is necessary to set up certain parameters within the control device and then connect the projector via a suitable cable to the computer (see D—19, Cables & Connections). The cable should be plugged into the ‘Computer In’ port on the projector and extra projectors may be connected, in ‘Daisy Chain’ fashion, using the ‘Computer Out’ port. A maximum number of 127 individually addressed projectors may be connected in this way.

The projector and computer send data to each other at RS232 levels. The following protocol must be specified for the computer’s serial port:-

Data Rate: 19,200 baud Data bits: 8 Stop bits: 1 Parity: None Handshake: None

The Data Rate can be changed to 9,600. For more information contact your dealer.

Data transfer to and from the projector is made up as a series of ASCII coded hexadecimal characters formed into message packets using the structure below:-

Address Header Data Length Data Checksum Delimiter

Address Projector address (01 - 127) consisting of two characters. Header Command instruction consisting of two characters. Data Length A two character number representing the data string length. Data Variable length string of characters. Checksum Two least significant digits of sum generated by adding all

previous pairs of characters.

Delimiter Carriage return.

It is recommended that the checksum calculation is used, however, it can be avoided by substituting two lower case ‘x’s instead of two calculated digits. This tells the projector to ignore the checksum and treat the message as being correctly received.

24 Preset settings This will use the factory default settings

to display an image. It will overwrite all previous changes for the currently selected channel.

30 Download channel data This will overwrite all existing channel

data for the specified channel. Care should be exercised in ensuring that wanted data is not deleted from memory.

31 Download computer card data This command could potentially use large

amounts of users memory.

32 Download submode data Care should be taken to ensure that the

settings do not exceed given ranges, otherwise use of new submode could produce unusable images.

33 Begin download card list This command tells the projector to over

write the existing computer card list and the associated submodes. Care should be taken if existing data needs to be kept.

34 Add computer card Adds a new computer card to the current

list. It does not overwrite any existing data.

35 Structure transfer complete Tells the projector that no more channel/

card and submode data is forthcoming.

36 Upload channel data request Data uploaded from the projector in this

way cannot be modified and sent back to the projector as a new channel without changing the status of the read/write byte.

Using an appropriate RS232 interface (see D—19, Cables & Connections) the projector can be used in conjunction with a third party switching device. Currently ‘Extron System 8’ and ‘Extron System 10’ are compatible with the projector.

The projector and external switching device communicate at RS232 levels using the following protocols:-

Data Rate: 9,600 baud Data bits: 8 Stop bits: 1 Parity: None Handshake: None

At present, an external switcher will allow you to control the lamp power, picture mute and channel change functions. Messages transferred to and from the projector are made up as a series of ASCII coded hexadecimal characters formed into message packets using the structure below:-

Header Data Length Data Checksum

Header Represents data type according to the table below. Data Length Will indicate the amount of variable length data to follow, in

bytes, not including the checksum.

Data Variable length string of characters. Checksum A checksum of XX will indicate that the checksum should be

ignored and the message treated as correctly received.

Header Message Data Meaning

04 Lamp Power XX Change lamp power to specified value.

00 = minimum power and FF = maximum.

07 Picture Unmute - Unmutes the Picture.
