Introduction

About this manual

Please note that this manual covers two versions of the Eclipse: the CS-450 external version, and the CS-460 internal PCI/ISA card version. While they share much of the internal circuitry with each other, some control methods are not available on the internal card version. Therefore, some parts of the manual may not apply to the version you have bought. Side-tabs are used in the manual to highlight areas that apply to the internal version, the external version, or both.

Features

The Eclipse provides high quality scan conversion (converting computer-type video signals into television-type video signals), along with easy to use genlock and overlay features. Its features and controllability make it the ideal method of overlaying computer titles and graphics - for studio use, data/time overlay, presentations, video titling and exhibitions.

The external unit is controllable via the on-screen display and push-buttons, infra-red remote control or directly by a computer's RS232 port - so all features can be easily accessed. The internal unit is limited to RS232 as standard, as it is intended mostly for system integration - infra-red control is possible with an optional Infra-Red Receiver

Module. All settings can also be stored in non-volatile memory, and the external version also features button-lock and Microsoft® serial mouse emulation.

For use in conjunction with other video equipment, the unit's built-in synchronization

(genlock) ability also means it can lock to an external video signal. Fine tuning of the subcarrier phase adjustment is also possible.

This manual outlines the many features of the Eclipse, how to use them, and how to get the best out of them. The different control methods are explained to allow you to choose the most appropriate for your own uses.

Hardware Setup (CS-450 external version)

We recommend switching off all equipment before starting the setup.

Connecting the CS-450 Eclipse to a computer and monitor

Disconnect the monitor from the computer at the computer's video output. Connect this cable to the 'PC OUT' connector on the back of the CS-450 Eclipse. Macintosh computers may require an additional cable. This will let you see the monitor as before, even when there is no power to the Eclipse.

Use the supplied computer-to-unit (HD-15 to HD-15) cable to connect the Eclipse to the computer monitor output. Macintosh computers may require an additional cable. Connect this to the 'PC IN' connector on the back of the Eclipse and to the monitor output on the computer.

Connecting the video outputs

The Eclipse provides three different output types to allow connection to various video displays and capture equipment (such as TVs and VCRs). The choice of output type depends on what your equipment can accept.

Composite Video - use the composite video cable provided to connect from the composite video output on the back of the Eclipse to the composite video input of your target video equipment - eg. video monitor, TV, VCR, etc..

S-Video - use the S-Video cable provided to connect from the S-Video output on the back of the Eclipse to the S-Video input of your target video equipment.

S-Video provides improved performance over Composite Video.

RGB - use the RGB out connector when the target device requires an RGBS (at

15.75kHz Horiz.) signal. This is for the converted PC image only and no external video signal will be present.

2

Connecting the video input (for Genlock , Overlay, or Mix functions)

The Eclipse has the ability to synchronize its video output with another video signal

(called 'genlocking'), or it can even superimpose its video output on top of another video signal (called 'overlay' or 'mix'). This is done by connecting a video signal to one of the

Eclipse's inputs, and selecting the appropriate genlock/overlay setting (see later in the manual).

Feed your video signal (if you want to genlock or overlay) into either the Composite

Video IN or S-Video IN connectors. You should also ensure that the signal used is of the right standard (PAL/NTSC), and that it is a clean, stable, standard signal. Video signals with a lot of noise, tape 'drop-out', or glitches may not be suitable - you will be likely to get poor performance with such a video input.

Connecting the serial cable (optional)

The Eclipse can be controlled from a computer, and used as a remote Microsoft® serial mouse emulator by connecting its RS232 port to a computer's RS232 port. See the sections on 'Mouse Control' and 'RS232 Control' later in this manual on how to use these features.

Connecting a power adapter

The Eclipse requires a 12v DC (minimum 350mA) power supply - see 'Technical

Specifications' for further information on suitable power supplies. Plug the power adapter into an AC outlet.

When you first turn on

Make sure that all leads are connected and that all other equipment is turned on - your computer monitor should be functioning normally. Select the correct line input (AUX or

AV channel) on the target video equipment. The TV should now be displaying the same picture as is on the computer monitor.

When the Eclipse is switched on, the green LED indicator on the front panel will illuminate and the OSD (on-screen display) will display the version and copyright details. If this does not happen refer to the troubleshooting section.

If there is a picture on the video monitor, but it is the wrong shape, position or color it may be necessary to alter some of the status settings before a good picture is displayed. For example: it may be necessary to switch to PAL or NTSC settings.

Further details on selecting the correct settings for your display follows in the

Advanced Features section.

If there is no picture on the video monitor then go to the troubleshooting section.

Front-Panel Control (CS-450 ext. version)

Control methods

There are 3 ways to control the CS-450 Eclipse:

1. By the buttons on the front panel

2. By the infra-red remote control unit

3. Directly from the computer via the serial (RS232) port

This section will describe what you can do with the 'quick-set' buttons on the front, which are detailed at the bottom of the front-panel. The text at the top of the panel refers to use when the on-screen display (OSD) menu is enabled when the MENU button is pressed and this, along with the infra-red and serial port control, is described later. The text at the bottom of the panel refers to the 'quick-set' buttons detailed here.

Shown below is a diagram that indicates the main features of the front panel.

Infra-red receiver

Front of CS-450 Eclipse showing panel buttons

Illuminated buttons

These indicate the current state of the unit, and are also used to change the unit's state.

MENU.

This is used to initiate front panel control of the unit via the on-screen display (OSD), and to select the various options and features to change, and is described in a later section. It illuminates green when power is on, and flashes if a button or infra-red lock is active.

O/SCAN -

. This enables and disables overscan mode - see the next section for more details on what 'overscan' is. The button is illuminated when overscan is selected.

4

FREEZE +

. This button freezes the converted computer signal. The button flashes when active.

MODE

. This button cycles through the genlock and overlay modes available. It illuminates whenever genlock or overlay is active. You should select the right

Signal Type before using this button (see On-Screen Display section).

FADE

. This button will fade the converted computer signal in and out, and flashes red when faded out.

Sounder

An internal sounder (buzzer) is used to confirm that a setting has changed with the buttons, or to indicate that the Eclipse is saving settings to non-volatile memory. You will hear it a fair bit during normal use, but it can be disabled if needed.

Special button usage on Power-up

Certain buttons can be held down when applying power to the unit, to perform certain special functions:

Factory Reset

. Hold down both the O/SCAN and FREEZE buttons when turning the unit on. This will reset the unit to Factory settings (and set the unit into NTSC video mode). It should only be used if the unit's settings give an invalid output that the user cannot exit from, as all user-settings will be erased by this.

Set to NTSC mode

. This is done by holding the O/SCAN button down when turning on the unit. This changes the non-volatile PAL/NTSC setting to NTSC, and will be remembered even when power is removed.

Set to PAL mode

. This is done by holding the FREEZE button down when turning on the unit. This changes the non-volatile PAL/NTSC setting to PAL, and will be remembered even when power is removed.

Special multi-hold buttons

Certain buttons can be held together when the unit is on to perform other functions.

Store Current Settings.

This is done by holding the MENU and FREEZE buttons in together for about 2 seconds, and can be done at any time. This stores the current settings (e.g. Overscan, Overlay mode, etc.) in Non-Volatile Memory, which will be read back the next time the unit is turned on.

This option will emit a high-pitched beep when complete to indicate that data has been successfully stored. If you manage to store an invalid setting, you may need to do a

Factory reset (see above).

If you hear high pitch beeps at other times, it indicates that other data is being stored into memory - eg. information the Eclipse has deduced about the graphics resolution coming from your computer, such as when you change your screen resolution.

Hardware Checklist (CS-460 internal version)

Your package should contain:.

Eclipse PCI/ISA card with white support pillar attached.

PC Monitor Y-splitter Cable.

Video Breakout Cable (with 2 x composite video and 2 x S-Video).

5-Pin mini-DIN to 9-way RS232 Cable.

Eclipse Instruction Manual.

Please note that this unit gets its power from a spare hard-drive connector cable within the PC. If you do not have a spare connection, you will need to use an optional hard-drive connector Y-splitter cable.

If you wish to use the Infra-red control features of the units, you will also need:

Infra-Red Receiver Module.

IRC4 Infra-Red Remote Control Handset.

(These items are not supplied as standard, as they will normally only be used once during the card's initial setup. Therefore a single Receiver Module & Remote Control can be used on multiple Eclipse PCI/ISA cards.)

6

Hardware Installation (CS-460 internal version)

Preventing static damage to your card and PC

The CS-460 Eclipse card is an electronic circuit, and as such is susceptible to static damage. To minimize the risk it should be handled by the edges only, and care should be taken that you don't touch the board's circuitry. Leave the card in the Anti-Static packaging until you are ready to install it in your computer.

Your PC is also susceptible to static damage, so follow the PC manufacturer's guidelines for installing an internal card. Never touch the internal components on the circuit board of the PC unless directed to. Seek help from your PC supplier if you are at all unsure about what to do.

CS-460 Eclipse PCI/ISA dual format

This card can be altered to be either PCI or ISA format, simply by undoing the four

'hex-nuts' holding the back-plate to the 15-pin HiD connections, rotating the back-plate

180 degrees, and

securely

replacing the 4 'hex-nuts'.

In the diagram below, the PCI format is shown in detail.

The actual look, and therefore the connections, will be different depending on which way round the back-plate is. The diagrams that follow will help to determine which way your card is configured.

Installation of the card in a PC

Please note: if you are at all unsure about how to install a card into your PC, seek help from your PC retailer or supplier.

Follow the steps below carefully. TV One's warranty does not cover badly installed cards.

1. Ensure your PC is turned off and unplugged at the AC Outlet.

2. Disconnect all cables from the PC.

3. Remove the cover of the PC - take care not to lose any screws.

4. Check that there is a spare 4-pin 'Hard-drive' power connector fly-lead - as used to power hard disk drives and CD ROM drives. This may be secured with a cable-tie, and will therefore require loosening. If no spare fly-lead is found, you will need to use a Y-splitter to split the power cable into two (not included).

5. Locate a spare slot to take either a PCI or an ISA card according to the format of the Eclipse card, and check that the Hard-drive power connector fly-lead will reach the slot's position. You may need to reconsider the slot to install into depending on the length of this power fly-lead.

6. Remove the blanking plate and securing screw from that slot position.

7. Carefully insert the Eclipse card into the required slot, and replace the screw that has been removed in step 6.

8

8.

Check that the card is secure, will not move, and that any neighboring cards will not touch the Eclipse card (and vice-versa) even if they move slightly.

9. Connect the Hard-drive power connector fly-lead to the CS-460 Eclipse card.

10. Replace the cover of the PC.

11. Reconnect all normal cables, and see the next section on how to wire up the card.

Connecting the VGA Y-Splitter cable

It is recommended to do this with the PC still turned off.

1. Plug the HD-15 plug on the Y-Splitter cable (there's only one) into your graphic card's output connector.

2. Your monitor can then be connected to the PC Out connector on the Y-Splitter cable - which is the shorter cable with the 'hex-nuts' on it.

3. Connect the remaining 15-pin in-line 'connector' connector to the appropriate connector on the Eclipse card (only one will fit).

Because the Y-Splitter cable is so short it should not degrade the video performance of your graphic card.

Connecting the Video Breakout cable

This cable plugs into the HD-15 connector on the Eclipse card, to provide a multitude of video inputs and outputs.

10

Video Inputs (for Genlock , Overlay, or Mix functions) - marked '1' on each connector

The Eclipse has the ability to synchronize its video output with another video signal

(called 'genlocking'), or it can even superimpose its video output on top of another video signal (called 'overlay' or 'mix'). This is done by connecting a video signal to one of the

Eclipse's inputs, and selecting the appropriate genlock/overlay setting (see later in the manual).

If you want to use this ability, feed your video signal into either the Composite Video IN or S-Video IN connectors (both marked '1'). You should also ensure that the signal used is of the right standard (PAL/NTSC), and that it is a clean, stable, standard signal. Video signals with a lot of noise, tape 'drop-out', or glitches may not be suitable - you will be likely to get poor performance with such a video signal.

Video Outputs - marked '2' on each connector

The Eclipse provides three different output types to allow connection to various video displays and capture equipment (such as TVs and VCRs). The choice of output type depends on what your equipment can accept.

Composite Video - use the composite video cable provided to connect from the composite video output (2) on the breakout cable to the composite video input of your target video equipment - eg. video monitor, TV, VCR, etc..

S-Video - use the S-Video cable provided to connect from the S-Video output (2) on the breakout cable to the S-Video input of your target video equipment.

S-Video provides improved performance over Composite Video.

Connecting the serial cable

The Eclipse PCI/ISA card needs to be controlled from the computer's RS232 port - or you will not be able to select many of the unit's functions. Alternatively, you can use the optional Infra-Red Receiver Module in combination with the IRC4 remote control.

11

When you first turn on

Make sure that all leads are connected and that all other equipment is turned on - your computer monitor should be functioning normally. Select the correct line input (AUX or

AV channel) on the target video equipment. The video display should now show the same picture as is on the computer monitor.

If there is a picture on the video monitor, but it is the wrong shape, position or color it may be necessary to alter some of the status settings before a good picture is displayed. For example, it may be necessary to switch to PAL or NTSC settings. Further details on selecting the correct settings for your display follows in the RS232 Control section.

If there is no picture on the video monitor then go to the troubleshooting section.

12

Reset switch (CS-460 internal version)

A reset switch is viewable beside the 5-pin mini-DIN connector on the back-plate of the card. It is a small micro-switch, and allows the user to restore the unit to Factory Settings.

This may be necessary if moving the card from one PC to another (eg. if the RS232 baud rate is different, and you want to reset it to the default of 9600 baud).

Side view of switch

Reset switch activation.

Performing a Factory Reset

1. Close down & turn off your computer.

2. Locate the micro-switch as shown in the diagram above.

3. Using a very small screwdriver, gently hold down the lever in the direction shown in the diagram above. Note that the micro-switches hinge is nearest to you.

4. Power-up the computer.

5. Release the micro-switch's lever about 1 second after turning on the computer.

Factory reset only occurs if the micro-switch is activated while the computer is being turned on - it will not occur at any other time.

(Pressing the micro-switch emulates the depression of both the + and - buttons on the external version of the Eclipse.)

NTSC selection

When doing a Factory Reset, you also change the unit to work in NTSC. If you require it to operate in PAL, you will need to use the RS232 Control method to select NTSC mode, and then do a 'Store Settings' so that it is used in the future.

Alternatively, if you have the Infra-Red Receiver Module, you can select PAL from the

Advanced menu using the on-screen display.

13

Infra-Red Remote Control

Introduction

By now you should have the unit powered up and working with your computer and TV. If you don't get an image on your TV, please refer to the Troubleshooting section at the back of this manual.

This unit has been designed for ease of use, and you should find most of the controls simple to understand and apply.

For external version...

If at any time you find that the remote control or front-panel buttons are not working, then you may have inadvertently pressed the LOCK button on the remote control. Lock mode is indicated by the green power button on the unit flashing - see later for a description of how to turn this feature on and off.

For internal PCI/ISA version...

The Infra-Red Remote Control is not supplied as standard with the internal version. If you have purchased the Infra-Red

Receiver Module, its cable can plug into the internal card's 5-pin mini-DIN (RS232) connector. You can then use the correct remote control (optional) by aiming it at the Infra-Red Receiver

Module, to control the internal card.

In any case, this section contains information detailing each function of the unit, and will therefore be needed even if you use

RS232 control.

What this section covers

All the infra-red remote control features of the Eclipse.

It explains the setup and adjustments for the unit and what effect they have on the final image.

How to store the settings so they are remembered by the unit for next time.

Therefore the following is required reading!

14

RESET

As its name implies, this resets the unit back to the last-saved user settings. It is useful if you want to clear any changes made to screen size or position. If you've saved an invalid setting to the non-volatile memory, you may want to do a Factory Reset - as described in the Front Panel Button section.

STORE

This button is used for saving new settings to the unit's memory and will be remembered even after the unit has been switched off. Just about all feature settings can be saved even Zoom mode and position. Note that Button Lock can be saved, but Remote Control

Lock cannot.

A high-pitched beep will be heard when this function is complete.

U.SCAN / O.SCAN

(Underscan / Overscan.) Pressing this button will toggle you between Underscan and

Overscan modes.

Underscan (sometimes known as Compress mode) will leave a border around your image.

Overscan has no border and the displayed image (when set correctly) is larger than your TV monitor screen.

This function is also available via the front-panel button labeled 'O/SCAN'.

The position and size of the image in both modes is user-adjustable, and the method of doing so will be described later under the SIZE and POS functions.

FREEZE

The Freeze function allows you to freeze the current image on the screen, and most of the settings of the unit itself. Pressing the freeze button again will unfreeze the image.

Note that the freeze function will only freeze the image on the T.V monitor - the image on the computer monitor will not be affected by this function and will carry on displaying images as normal.

No other features are accessible while in Freeze mode, with the exception of RESET,

MODE and FADE. These functions are also available via the front-panel buttons of the same name.

AUTOSET

This is a powerful feature of the Eclipse unit. Once activated this feature will scan the incoming computer image to determine its size and position - thus optimizing it for display on the desired TV unit.

When your unit first encounters a new screen resolution or refresh rate, it will make a guess on how best to display this on a TV. Sometimes, the guess needs 'refining', and this function makes the unit itself search for the image edges to improve on this.

Until you run this feature (assuming you have not previously done so), the unit will have 'guessed' the right settings in order to give a video output that is centered and sized correctly. This 'first guess' is exactly that: a guess - as graphics cards in computers have very few 'standard' resolution/refresh rate settings, and all other settings vary drastically from computer to computer.

This feature requires that the top, bottom, left and right edges are of a certain minimum brightness - i.e. certainly not black, but the actual level can be adjusted and the method to do so is described later. Almost all Windows programs will use the full size of the display which is fine, but some DOS programs (especially at the

DOS prompt) may not do so which will cause a problem for the unit.

Only use this feature when the full area of the computer screen is being used - this will ensure that the unit 'sees' the edges correctly, and performs its task without errors.

If you have a problem, a 'Manual Set' mode is available to fine tune the values created by this mode. Or simply reactivate this feature when your computer screen is being more fully used.

Once complete, the Auto Set routine will remember this particular computer resolution so that you should not need to re-do the routine (you'll hear a high-pitched beep to indicate this). The only exception is if you change the refresh rate (when Auto Set should be run again), or do an Factory Reset (which will delete all settings learnt by the unit).

A high-pitched beep will be heard when this function is complete.

FILTER

This button will toggle between 2 and 4 line flicker reduction modes. Depending on what you are displaying, the size of the image, fonts you are using and the computer image resolution will depend on what flicker reduction best suits your image.

4-line filter will soften the image slightly but will retain most of the image detail and make the image more stable (this is also the unit's default setting). This is perfect for higher resolutions and CAD drawings.

2-line filter will sharpen the image but you might get a slight loss of fine image detail and some flickering. It may also improve the display when in Zoom mode.

16

SIZE & POS

These buttons allow you to adjust the Underscan or Overscan size and position on the TV

(whichever is currently selected). You can then use the arrow keys to adjust the horizontal and vertical size or position of the image being displayed.

Please note: you should ideally have done an AutoSet before making these adjustments, so that the unit knows the size of the "incoming" computer image.

The Eclipse has 2 modes of display as mentioned earlier (Underscan or Overscan).

So it is important to have the correct one selected before proceeding to change the values. The 'O/SCAN' red LED will be lit in Overscan mode - i.e. when the image should fill the screen. Underscan modes should always be adjusted to leave a slight black border around the image.

Only SIZE or POS is active at any one time, but you can easily switch from one to the other.

The values are also separately stored for NTSC and PAL outputs - adjusting one will not affect the other.

Once adjusted, STORE the setting for future use.

Note that you are setting the screen size for one particular TV (the one you are watching the results on), and the size may appear different on another TV. This is not a fault with the unit, but merely demonstrates that no two TVs are exactly alike.

ZOOM

This function allows you to view a section of the video image at twice the normal size, and is useful for showing computer images and programs in more detail. This could be useful in training applications.

Enter the Zoom function by pressing ZOOM on the IR remote control. Pressing ZOOM again will return you to the normal viewing size.

You can then 'pan' around the image by using the arrow keys to slide the image around.

It is possible to STORE this setting to make the unit start-up (from power on) in

Zoom mode, and in a particular pan position. This may be useful for certain applications - such as video conferencing when using a video-in-a-window card.

You can adjust other settings while in Zoom mode.

You may need to press the PAN button to restore control over the Zoom position, after adjusting other settings.

MODE (Overlay mode)

This cycles through the different genlock / overlay modes available, which are (in order):

PC Out - normal computer to video scan conversion.

17

Genlock - as PC Out, but synchronized to a video input.

Overlay - the converted computer video signal is superimposed on top of a video input.

Mix - the converted computer video signal, and the video input, can be faded between one another.

The MODE button on the unit illuminates when in genlock, overlay or mix mode.

This button can be pressed when the video image is frozen.

PLEASE NOTE that only one input (composite video or S-video) can be active at any one time, and should be set prior to using the genlock/overlay/mix modes - see next section

"On-Screen Display". Otherwise, you may get a scrambled picture.

Detailed descriptions of each mode are in the "Using Genlock, Overlay, and Mix" section.

KEY

This allows adjustment of the Key Level used when in Overlay mode.

Press the up-arrow key to increase this value, and the down-arrow key to reduce it.

A higher value will mean that fewer colors (just the brighter ones) will be overlaid.

A lower value will allow more colors to be overlaid.

Full details can be found in the "Using Genlock, Overlay, and Mix" section..

FADE

This will fade the converted computer signal in or out (toggling from one to the other).

The FADE button on the unit flashes when the image is faded out.

This button can be pressed when the video image is frozen.

Full details can be found in the "Using Genlock, Overlay, and Mix" section..

LOCK - External version only.

Pressing this button once will disable your Eclipse's front panel buttons. To re-enable the front panel buttons simply press the LOCK button again. This setting can be STOREd, to prevent others from adjusting the unit without the remote control.

Pressing the button twice (within 1.5 seconds of each press) will lock both the front-panel buttons and the remote control - use with care! This setting cannot be stored, because of course the remote control (and buttons) are disabled by this time.

The Power LED will flash slowly when the front-panel buttons are disabled.

The Power LED will double-flash when both buttons and remote control are disabled.

18

Remove and then restore power to the unit to bring the remote control back to life if you have disabled both the buttons and the infra red remote control.

The Factory Reset method (described in the Front-Panel section) will still work if you have STOREd a button lock and don't have the remote control handy to correct this.

This feature is intended for use where the settings of the unit should not be disturbed - eg.

in an educational environment, or at an exhibition.

LEVEL

This button allows internal settings to be adjusted, by subsequently pressing a number button (within 1.5 seconds), and then the up/down arrow-keys to adjust the level itself.

LEVEL 1 - will adjust the brightness of the image coming from the unit. This is very useful to match this unit's brightness with that from a video player, but be careful not to 'over-saturate' the signal when increasing the brightness, or some colors (eg. yellow) may become very washed out.

LEVEL 2 - will adjust the AutoSet sense level, from 1 through to 3. A lower setting (using the down arrow-key) will allow darker image edges to be detected.

The default is 1. If after running AutoSet you are left with an image that is too big for the TV screen it may be because the image is too dark and the unit cannot find the edges of the picture. Altering the sense setting will change the brightness needed for the unit to find the correct edges satisfactorily. Run AUTOSET after changing the sense setting to ensure a good image on the TV.

E.g. Press LEVEL followed by 1, and then adjust the picture brightness with the up and down arrow keys.

This feature times-out after about 10 seconds to prevent further accidental changes.

How to do a 'manual set'

This function should only be needed when the AutoSet has failed for some reason, or the

Computer image that you are using has a dark background which Auto Set cannot see.

Please read the notes on AutoSet & Level adjustments in the Infra-red Remote Control section before adjusting these parameters, in case something else will solve the problem.

With these adjustments you can manually set whichever area of the computer's image is to be used for display on your TV.

It is highly recommended that this method is only used when in Underscan mode, or you will not know if you've adjusted the values correctly.

Press AUTOSET on remote control twice (within 1.5s) - two 'beeps' will be heard.

Adjust Top and left-hand edge by pressing the arrow keys.

Press AUTOSET again.

19

Adjust Bottom and right-hand edge by pressing the arrow keys.

Press AUTOSET - this will give a high beep to indicate that this has been saved.

Manual set mode times-out after 20 seconds - ignoring any settings.

20

On-Screen Display

(This feature is only usable on the CS-460 internal PCI/ISA version if the Infra-Red

Receiver Module is being used in combination with a remote control.)

Introduction

As well as being controlled via the Infra-Red hand controller, the Eclipse can be controlled further using an On Screen Display menu (OSD).

The external unit's OSD can be activated and controlled by using the front panel buttons marked MENU, + and -.

For the internal PCI/ISA unit, the 3 buttons on the remote control detailed in the 'Infra-Red

Remote Control' section in this manual do the same thing.

SIZE POS

MENU - +

PAN

New function for these buttons, when used with

the Eclipse PCI/ISA internal card

I.e. L.CLICK becomes MENU, D.CLICK becomes -, and R.CLICK becomes +.

Activating & Navigating the On-Screen Display (OSD)

Pressing the MENU button will activate the On Screen Display (OSD) function, presenting you at the start of the Menu Structure. The top line of the OSD is the menu name you are currently in, while the lower line will indicate what sub-menu is available, or the feature that can be altered.

Once in menu mode the buttons - and + can be used for adjusting the various settings that will be displayed. Sub-menus (indicated by '...' trailing the sub-menu text on the lower

OSD line) can be entered by pressing +.

You can 'navigate' to the next feature in the menu list by pressing the MENU button again.

At the end of every menu or sub-menu list, will be an 'Exit...' option, and + will then exit back to the previous menu, or terminate the OSD.

In any case, the OSD will terminate after approximately 25 seconds of inactivity.

Flicker Red.

Performs the same function as mentioned with the infra-red remote control FILTER button

(flicker reduction), where you can set the flicker reduction to either 2 line or 4 line use.

21

Auto Set

When 'AutoSet 0' is displayed press the + button to start this function. The number will increment as the feature gradually progresses, ending in a high-pitched 'beep' (on the external version).

Overlay...

Signal Type - selecting the video input

This selects either 'CVid' (composite video) or 'SVid' (S-Video) input. When genlocking, overlaying or mixing, you must specify which input to use. The default is composite video, but you can easily select the appropriate input and STORE it.

Press - to select CVid, and + to select SVid.

Do this before using Genlock, Overlay or Mix modes, or you may get a scrambled picture on the output.

It is recommended that you remove unused inputs from the unit - e.g. if you're using a composite video input, disconnect the S-video input. This helps to prevent

'crosstalk' between two different signals.

See the "Using Genlock, Overlay, and Mix" section for more information.

Mode

This changes the unit's overlay mode - make sure you've selected the right Signal Type first.

Press the + and - buttons to cycle through the four different options :

PC Out

disables all genlocking and overlay functions, so that video inputs can be removed and the unit then functions as a normal scan converter.

Genlock

will lock the unit to an incoming signal.

Overlay

will lock the unit to an incoming signal and overlay the computer's image on top of it. A key signal is generated internally, based on the computer image's brightness - see Key Level later.

Mix

is similar to Genlock, but the Fade option behaves slightly differently.

If you lose the video picture, because a valid video signal is not present, press + until the PC Out mode is re-selected.

See the "Using Genlock, Overlay, and Mix" section for more information.

Keyer

This changes the unit's built-in overlay circuit, to give different levels of softness and hardness to the computer's image when in Overlay mode.

PC Out, Genlock, and Mix mode are not affected by this feature.

The Key Level function also affects Keyer results.

22

Press the + and - buttons to cycle through the four different options :

V.Soft (Very Soft) - use where you would like your overlaid graphics to blend in with the background video image. Most colors will blend with the video rather than replace it, depending on the Key Level.

Soft - similar to V.Soft, but more colors appear 'hard', i.e. replace the background video rather than blend with it. Very dark colors may not appear at all.

Normal - is the recommended setting (and the default). This should give a good range of colors that blend (the darker colors), and replace (the brighter colors).

Dark colors may not appear at all.

Hard - almost all colors will either not appear (those darker than the Key Level) or replace the background image (those brighter than the Key Level), with the few colors in between blending with the video background.

See the "Using Genlock, Overlay, and Mix" section for more information.

Key Level

A value ranging from 0 to 250, in steps of 5, which determines which colors are bright enough to appear overlaid. Colors whose brightness (i.e. luminance) is above the Key

Level will overlay - with most of the remaining colors not appearing. 'In-between' colors

(i.e. those around the Key Level value) will appear blended with the background video to various degrees, depending on the Keyer setting.

Press the + and - buttons to increase and decrease this value.

Decreasing the value will allow more color shades to overlay, since their brightness is more likely to be above the Key Level.

Increasing the value will reduce the number of color shades that appear overlaid, since less of them (i.e. only the bright ones) will have brightness values above the

Key Level.

In general, white is the easiest "color" to overlay since it's the brightest. This is followed by yellow, cyan, green, magenta, red and then blue. Pure blue is often tricky to overlay (since it is very dark), so it is best avoided.

Note that picture noise can become prevalent where the color being overlaid exactly matches the Key Level, since minor changes in the computer video signal will give large (amplified) changes in the overlaid result. Experiment with different Keyer and Key Level settings.

See the "Using Genlock, Overlay, and Mix" section for more information.

Fade Speed

This value affects the speed at which the fade will be done, when either the FADE button on the remote control or the front-panel is pressed.

Press the + and - buttons to increase and decrease fade speed.

23

The minimum value of 1 will fade the slowest, in about 2 seconds.

The default of 5 will take about 0.5 of a second.

The maximum value of 25 will fade almost instantly.

See the "Using Genlock, Overlay, and Mix" section for more information.

SC Phase

This value allows fine adjustment of the subcarrier phase when genlocking, overlaying, or mixing. This should never normally require alteration.

Press the + and - buttons to increase and decrease SC Phase.

The minimum and maximum values are -12 degrees and +12 degrees, and are provided for fine-tuning of the overlaid signal's color phase.

Leave the value at 0 degrees if you at all unsure about changing it.

Other TV One products are available giving a full 360 degree adjustment.

See the "Using Genlock, Overlay, and Mix" section for more information.

Exit

To exit these adjustments press the + button when 'Exit...' is displayed.

Screen Size...

This allows entry into a sub-menu (using + button), to set the SIZE and POS settings also found on the infra-red remote control.

Out H-Center - altering the display's horizontal screen position

Pressing the + button will move the image to the right, pressing the - button will move it to the left.

Adjust until the image is centered horizontally on the screen.

Out H-Width - altering the display's width

Press the + button to increase the width of the picture and - button to decrease it.

Adjust until the desired width of the image is obtained.

Out V-Center - altering the display's vertical screen position

Press the - button to move the picture up the screen and + button to move it down.

Adjust until the image is centered on the screen vertically.

Out V-Height - altering the display's height

Press the + button to increase the picture height and - button to decrease it.

Adjust until the desired height of the image is obtained.

If you wish to go back and change any of the above adjustments press the MENU button until the desired adjustment is being displayed, then + or - to alter its setting.

24

Exit

To exit these adjustments press the + button when 'Exit...' is displayed.

Manual Set...

This function should only be needed when the AutoSet has failed for some reason, or the

Computer image that you are using has a dark background which Auto Set cannot see.

Please read the notes on AutoSet & Level adjustments in the Infra-red Remote Control section before adjusting these parameters, in case something else will solve the problem.

With these adjustments you can manually set whichever area of the computer's image is to be used for display on your TV.

It is highly recommended that this mode is only used when in Underscan mode, or you will not know if you've adjusted the values correctly. The 'VGA Store' option can be used to save your new settings in the unit's memory.

Follow the method listed below, pressing MENU between each step, to optimize your display:-

VGA Left

Adjust this value using the - button until you notice that some of the image is lost, and then press + to come back one step.

VGA Width

Do the same for the right hand image, but this time pressing + until the image just starts to be lost, and then press - once.

VGA Top

Press the + button until the top edge of image is lost, or becomes discolored then press - once.

VGA Bot (bottom)

Press the - button until the bottom edge of image is lost, then press + once.

If you wish to go back and change any of the above adjustments press the MENU button until the desired adjustment is being displayed then + or - to alter its setting.

VGA Store

Press + once to store your new settings. They will now be remembered in the Eclipse's memory even after the power is switched off.

Exit

To exit these adjustments press the + button at this prompt, this will return you to the main menu structure.

Advanced...

These options are described in the next section.

25

Advanced Menu

These features control the basic operation of the unit in order to comply with the operating environment - e.g. selecting PAL or NTSC video standards, adjusting RS232 controls, etc.

They are accessed in the same way as the previous features - i.e. press the MENU button repeatedly until the LCD displays the message 'Advanced...'. Then press the + button to select the Advanced sub-menu.

Subsequent pressing of the MENU button will select the next Advanced feature to alter.

Any of these new settings can be stored using the 'Store Settings' multi-buttons (hold

MENU and the + button together for approximately 2 seconds).

Advanced...

Video Standard - PAL/NTSC

The Eclipse can switch between PAL and NTSC standards with ease.

Press the - button to switch to NTSC mode. Press the + button to switch to PAL.

Screen Size settings are remembered separately for PAL and NTSC, so changing the Screen Size settings in NTSC will not affect the PAL settings.

If you are using the Overlay features of the unit, make sure you select the correct Video

Standard for the reference video signal being used - the two should be the same.

Sense - for AutoSet function

The sense level relates to how the Auto Set routine views the video input from the computer. If running Auto Set produces a resultant image that is too big for the TV it may be because the image is too dark for the Eclipse to correctly find the edges of the picture.

Altering the sense setting will change the brightness needed to find the edges satisfactorily.

A setting of 1 will sense 30% brightness levels, 2 will sense 60%, and 3 will sense

90% (approximately). 1 is the default, and should be fine for almost all screen displays.

Run the AUTO SET after changing the sense setting to ensure a good image on the

TV. If the image is still not good enough it may be necessary to set the Eclipse manually - see Manual Set.

To increase the sense value press the + button. To decrease it the press the - button.

Brightness

This level will adjust the scan-converted computer signal brightness.

Increase this value to make the signal brighter, decrease it to dim the image.

The default value of 130 should give a normal 1v peak-peak signal on the composite video output when fed a normal PC's white level. This value should only be adjusted if this is not the case.

26

Setting the level too high can easily result in some colors (notably yellow) being

'clipped' or over-saturated.

RGB Term. - Input impedance

This relates to whether or not the Eclipse is terminating the computer monitor output from the computer with a 75 Ohm impedance.

Usually the Eclipse will set the termination automatically ('Auto' mode), by sensing whether a computer monitor is linked into the circuit as well (i.e. to the 'PC OUT' connector).

However, if necessary, it is possible to turn the termination off - for example if the

Eclipse does not sense that the monitor is attached, which would result in

'double-termination' of the RGBHV signals.

Press the - button to turn the termination off, the + button to switch to automatic mode.

RS232 - Control/Mouse

This switches the use of the RS232 serial port between computer control and Microsoft® serial mouse emulation

In order to use the remote control to emulate a mouse, this RS232 adjustment must be set to 'Mouse' mode. Similarly, to use a serial link from the computer to control the Eclipse, it must be set to RS232 Control mode.

Note that the default is 'Control' mode - you must switch to 'Mouse' mode in order to enable the mouse emulation.

Press the - button to switch to Mouse mode, and the + button to switch to RS232

Control mode.

Baud rate - for RS232 control

In order to control the Eclipse from the computer it is necessary to set the same baud rate for both the unit and the controlling computer.

Press the + or - buttons to change to the required number. The Eclipse does not display the actual baud rate, but a number relating to it. The table in a later section on 'RS232 Control' shows which Baud rate each number relates to. For example: to set to 9600 Baud the number must be 23.

"9600,N,8,1" is the default setting - i.e. no parity is used, 8 data bits are required, and 1 stop bit.

This number is only used in RS232 'Control' mode. 'Mouse' mode ignores this number, and always uses 1200 baud.

RS232 ID

This ID code can be used where multiple Eclipses are all linked via a serial cable to the same computer. The ID can be altered so that each unit's ID is unique, and thus each unit

27

could be adjustable by itself - with one serial port. This feature is described further in the

"RS232 Control" section.

Sound - on/off

The internal sounder is used to give an indication of whether a variable has been changed, or if the Eclipse is saving settings to non-volatile memory. If you do not wish any audible indications to be present, the sounder can be switched off.

Normal beeps indicate that a feature or value has been changed.

High-tone beeps indicate that something has been written to the unit's Non-Volatile

Memory - for example when doing a Store Settings, Factory Reset, AutoSet, or when a new screen resolution/refresh rate combination has been detected.

Press the - button to turn the sound off, the + button to turn it on again.

IR (Infra-red) - on/off

As there are many different methods of controlling the Eclipse, multiple uses could be confusing.

This feature is useful where 2 or more units are present in an environment, so that only one unit will respond to the infra-red remote control.

It can also be used in situations where stray or random IR signals may be picked up

- or even to prevent others from remotely altering the unit's features.

In order to switch off control from the infra-red remote control press the - button, or press the + button to accept it.

Note that this is a separate feature to the LOCK button found on the remote control.

Sync Out - comp. sync polarity

The Eclipse can output either negative going or positive going composite sync on pin 13 of the RGB Out connector. It is necessary to switch the Eclipse to give the correct sync.

outputs for your display.

By default a negative-going composite sync signal is output.

Press + to change to positive-going (+CS), or - to select negative going (-CS).

Disp Credits (internal PCI/ISA version only)

By default, the CS-460 Eclipse PCI/ISA will always display 'credit' information when powering-up. However, this feature can be turned off in situations where a system integrator needs to remove this.

Set to 'On' to always show this message when powering-up.

Set to 'Off' to not show this message when powering-up.

Note that you'll need to do an immediate STORE in order to remember any change in this setting, or it will have no effect.

28

Total Lines - information

This simply details how many scan lines are in the incoming PC picture - including blanked lines that are not normally viewable, so a 1024x768 image might actually have a total of 806 lines in it, with 38 of them used for 'vertical blanking'.

Vert Freq - information

Again, this is just for information, and shows the vertical refresh rate of the incoming PC signal. Multiply this by the 'Total Lines' value to give the horizontal refresh rate. While high refresh rates are generally more acceptable when displayed on computer monitors, the

Eclipse prefers a low refresh rate so that it's capture circuitry has more time to capture more pixels, thus giving a clearer picture.

Exit

To exit these adjustments press the + button at this prompt, this will return you to the main menu structure.

29

RS232 Control

Setup

All of the functions of the Eclipse can be controlled from the Computer, using the RS232 port on the unit.

Using an appropriate cable and software, it is easy to communicate with the Eclipse, but before communications can be established first set the computer's serial port to:

8 bit data, no parity, 1 stop bit.

Either no flow control, or hardware (RTS/CTS) flow control.

Set the Baud rate on the computer and the Eclipse to the same value (usually 9600).

Sending commands

Commands are sent over the RS232 in one of two ways:

Send the 'adjust name' followed by = and a

number

(plus a carriage return) to alter any setting you see displayed on the lower line of the LCD display. E.g. If you were using a terminal emulator program, you could type the following command to immediately set flicker reduction to 2 lines:-

Flicker Red = 2

Send just the 'adjust name' (plus a carriage return) to retrieve back the current value for a setting. E.g. Typing the following returns the correct value back from the

Eclipse unit (e.g. '2'):-

Flicker Red

Responses to commands

The response from the Eclipse can be one of three things:

? if something is not understood, e.g. an adjust name is misspelt (note that this can happen

while

sending an invalid command, not just at the end of the command);

> if the command has been executed; nnnnn (i.e. a five digit number from 0 to 99999, followed by a CR and LF) if a setting value is returned. Numbers are padded to the right with spaces.

Notes on sending commands

Settings that are one of two values (e.g. NTSC or PAL), have to be sent as 0 or 1.

Similarly, options with, for example 4 settings (eg. the Mode feature) need to be sent as a number from 0 to 3.

30

You only have to send a maximum of 4 characters in order for the command name to be recognized - e.g. "Flicker Red = 2" could be shortened to "Flic = 2".

Spaces and line-feeds (ASCII code 10) are completely ignored.

You must always send a carriage-return (ASCII code 13) at the end of your command or value request.

The Eclipse's response should at most be within 40ms of the receipt of the carriage-return character. But of course delays due to slow baud rates will play a greater part than this.

The Eclipse's input buffer is limited to 32 bytes, so do not send any more characters

(including CR, LF, etc.) than this.

For more information on controlling the different functions see the relevant sections earlier in this manual.

Restricting RS232 commands to certain units

If you have a number of units all connected to the same PC's serial port (i.e. running in parallel), then you can use the RS232 ID feature to restrict certain commands to go to only certain Eclipse units. The following points outline this method:

Make each 'RS232 ID' setting unique to each Eclipse, unless you want two or more units to respond to the same commands, in which case make them the same ID value. The default value is 0.

Send the command 'ID Restrict nnn' where nnn is the number of the Eclipse unit you wish to control (from 0 to 255).

Follow this with whatever commands you wish to send. Units where 'RS232 ID' is not identical to the 'ID Restrict' value will not respond to or acknowledge these commands.

To disable this feature, you have to make the RS232 ID the same on all units

(recommended value 0), and of course set 'ID Restrict' to this value.

Changing Baud Rates

Details on how to change the Baud rate are in the Advanced Features section of this manual, but the relationship between number and baud rate is given in the table below.

Any odd number up to 191 can be selected, but only certain Baud rates are generally used.

The most common ones are outlined in the table below. For numbers not included in the table, the baud rate associated with those numbers can be found by using the following equation:

Using Genlock, Overlay, and Mix

Probably the reason why you bought the Eclipse was to use these features, so this section is dedicated to describing these in more details.

The above diagram gives an idea of how the unit's overlay circuit functions.

Video (either composite or S-video) is fed into the unit, and the Scan Converter circuitry is

'locked' onto this. The Scan Converter output is fed to the Video Mixer, where it is mixed accordingly to the Key signal from the Keyer circuit.

Note that the RGB Output does not pass through the Video Mixer and hence cannot support overlay features.

Advantages of this circuit

A different method of overlaying is to fully decode the incoming video signal into separate components (RGB or YUV), mix this with the scan converter components, and re-encode back to video. The Eclipse's method provides several advantages over this method:

The video input signal is never decoded, so remains at a very high bandwidth especially true when using a composite video input.

Signal delays (from video input to output) are minimized to approximately 20ns.

Sync pulse widths and subcarrier frequency of the video input remain unchanged.

Video input sync & subcarrier SC/H timings are unaffected.

Keyer circuit

The exact method that the Keyer generates the Key signal depends on the overlay mode being used (Genlock, Overlay, Mix), and other signals such as Keyer (V.Soft / Soft /

Normal / Hard), Key Level, and whether the computer overlay portion is faded or not.

35

The following table should help to explain the difference between these four modes of operation.

Overlay mode Description

PC Out Outputs only the computer image. Video input is ignored.

Genlock Outputs only the computer image. All sync, subcarrier and video levels are generated by the scan converter, but locked to the video input.

This allows use in situations where a TV or video monitor should be 'in-sync' with other equipment.

Overlay

Mix

Overlays computer image on top of video input, based on Key Level and Keyer setting. Sync and subcarrier signals are direct from the video input

(i.e. unit does not re-generate them).

Overlays whole computer image (even black areas) on top of video input. Sync and subcarrier signals are direct from the video input (i.e. unit does not re-generate them).

Effect of fade

Fades computer image to black level.

Fades computer image to black level.

Fades computer overlay image out, to reveal video input behind it.

Fades completely between computer image and video input.

Overlay mode function

This is the most complex to understand, but in general:

The color content of a computer graphic pixel is ignored - the luminance is of sole importance. White is the brightest (highest luminance), followed by yellow, cyan, green, magenta, red, blue (and black).

Colors much brighter in luminance that the Key Level are overlaid - i.e. they replace the video background.

Colors slightly above the Key Level are slightly transparent.

Colors at the Key Level are blended approximately 50% with the video background.

Colors slightly below the Key Level are more transparent.

Colors well below the Key Level are not displayed at all.

The level at which colors become opaque or transparent is set by the Keyer value

(V.Soft / Soft / Normal / Hard).

With a Hard Keyer setting, color luminances do not have to be much higher or lower than the Key Level to become fully overlaid or not displayed at all.

36

With a V.Soft Keyer setting, a broad range of color luminances will blend in with the video input.

Overlay mode in everyday use

The most common application is to overlay some form of graphics or text on to a video background, but by changing the text or graphics slightly, and careful alteration of the unit's settings, you can easily improve overlay quality.

Use anti-aliased text fonts wherever possible. This ensures that the edges of the fonts are smoothed, so that the overlay circuit's softer Keyer settings will blend them in to the video background - resulting in a far more professional result.

Choose darker colors in your text and graphics carefully. The wrong color (eg.

dark blue) may not overlay at all. Use a slightly lighter tone to improve overlay.

If you are overlaying very similar text or graphics, choose the one Keyer setting and Key Level that will work best for all of them, and then STORE it. The unit will remember this setting until it is next changed (or erased).

Always experiment with the Keyer setting and Key Level for the text or graphics you want to overlay. There will be an optimum setting.

Use with a monochrome composite video source

Such a video source won't have a subcarrier burst for the Eclipse to lock on to, so be aware of the following points:

You can feed a monochrome source into the unit provided that you do not use the

Genlock mode (use Mix mode instead). In Genlock mode, a subcarrier signal will be present that will not be valid.

For optimum clarity, feed the monochrome signal into the luminance (Y) pin on the

S-Video input. You can leave the chrominance signal unconnected. This will give a sharper overlay signal, and without chroma-artefacts that may be present if colors are attempted to be overlaid. This will also allow you to use the Genlock mode, but you will need to make up a special cable for this arrangement.

Use with RGB Out

If you are using the RGB output at the same time as using the Genlock, Overlay or Mix modes, be aware of the following:

The RGB output uses the composite video output signal, along with the red, green and blue signals, to feed a TV or VCR.

If you are using either the Overlay or Mix modes, a suitable composite video output signal is only present if your Signal Type (i.e. input source) is also set to composite video.

37

PC Out and Genlock modes are fully compatible with the RGB output, irrespective of the Signal Type.

If you have made your own RGB output cable, using the composite sync signal on pin 13 (instead of the composite video signal), this limitation does not apply.

Limitations of the genlock circuit

The Eclipse is designed to work with a reasonably stable video input signal, but can handle most VCR playback and other non-stable sources.

If you experience problems such as color loss (total or brief), sync loss, or picture disturbance at the top of the screen, the most likely cause is a poor quality video signal - such as one containing dropouts, sync loss, sync glitches, drifting color subcarrier frequencies, etc..

38

Mouse Emulation (CS-450 external version)

Introduction

The CS-450 Eclipse has an RS232 communications port that can be made to emulate a

Microsoft® Serial Mouse, and all the features are controlled from the infra-red remote control. This section details how to setup and use this feature.

Please note that it is not possible to emulate a PS/2-type mouse with the Eclipse.

Hardware setup

Setup of this feature requires the connection of an RS232 cable. Either: use a (null-modem) serial cable to link from the Eclipse's RS232 connection to the first spare COM port on your PC (usually COM2, but use COM1 if it's available); or, disconnect your serial mouse from your PC and use TV One's RS232 Sharer

Cable (optional) to link from your PC to the Eclipse - plugging the mouse back into the RS232 sharer unit.

Eclipse setup

Make sure that RS232 mode is set to Mouse (and not 'Control') within the Advanced menu of the On-screen Display. ('Control' mode is the default.)

Using the mouse emulator

The Eclipse uses the computer's standard mouse driver saving the need to load additional software, just turn your computer on with Eclipse attached as described above.

If you are using an RS232 sharer cable, both the existing mouse and the Eclipse will share the same COM port and software driver.

If you are using a separate COM port for the Eclipse, your PC may recognize that a Mouse is attached when booting up. If it doesn't, run "Add New Hardware" from the Control

Panel to automatically install the "Standard Serial Mouse" driver.

You can now use the four arrow buttons to move your mouse pointer around the screen.

L.CLICK (left click) has the same function as a single left click of a standard mouse button.

D.CLICK (double click), has the same function as a double left click of a standard mouse button.

R.CLICK (right click), has the same function as a single right click of a standard mouse button.

39

Toggling Zoom/Pan and Mouse modes

Both the Pan feature and Mouse emulation feature can be used at the same time, and you can toggle the arrow-key usage by pressing the PAN button on the remote control.

If you find the arrow-keys not controlling the mouse pointer, simply press PAN once to de-select PAN mode.

Similarly, to re-activate PAN mode (to slide a zoomed image around the screen), press PAN again

Appendix A - Get the most from your unit

The aim of this section is to help you exploit some of these applications and functions to get the best possible results from your unit.

Hints & Tips

1. Use S-Video in preference to Composite Video, if your equipment has such an input. S-Video keeps the color and brightness in a video signal separate, whereas composite video requires extra filters to separate them electronically - these filters degrade the image.

2. Don't forget the ZOOM. If you have problems reading the small text, then selecting the ZOOM mode will make things much easier, especially if using the

Composite Video output. This is particularly useful for presentations.

3. Zoom modes may require a different Flicker Reduction setting. Lowering the

Flicker Reduction value may help to increase legibility of small text.

4. The lower the graphics resolution and refresh rate, the better the image quality.

All scan converters store the computer image to be converted to video in their own internal memory, and to do so the computer image has to be 'sampled' many times during each scan-line. Each sample stores one pixel of information in the memory. The number of samples taken is proportional to the image quality - i.e.

the more samples the better. Higher graphic resolutions take less time to display each scan-line than lower ones, so it means that there will be more samples per line for lower resolution modes because there's more time for more samples to be taken - and hence will give a better image quality.

5. The lower the graphics resolution, the better the 'vertical' image quality. Video monitors have a fixed number of lines available for displaying pictures - for PAL it is 576, for NTSC it is 480, although some of these are off the top and bottom edges of the screen. So the more scan-lines a graphics resolution has (e.g.. an

800x600 resolution has 600 scan-lines), the more difficult it is for your unit to squeeze all these lines into the limited number available on the monitor. So lowering your graphic resolution will help improve image quality. (Remember to run AutoSet after you change the resolution)

6. Cables and Connectors. Using good quality cables and connectors like the ones supplied with your unit and ensure that all connectors are properly connected to help maintain a high picture quality.

7. Designing your Display or Presentation. When setting up an image for display or putting together your presentation, keep in mind that people might have to view it from a distance. Using a font that is well defined, graphics and pictures that are uncluttered will all add to the legibility of your display or presentation. Try to make text well spaced and larger than you normally use. Think about the colors

43

you are going to use, colors that standout from each other are better for viewing from a distance. As mentioned earlier choosing the right screen resolution will also add to the clarity and quality of your display. It is worth spending some time experimenting with different screen resolution and settings which will optimize your unit to use its full potential.

8. Freeze function. This function is useful if you wish to change to another image or layout while maintaining an image on your monitor, Let's say that you wish to change from a program that is displaying text to a program that displays a graphic. Before you close the text display program freeze the image on the video monitor that you are using, you are then free to change to the graphic image program. Once this is done you can unfreeze the image on the video monitor which will then display your new image. All that the people watching the video monitor would have seen is the text image followed by the graphics image they will not have seen you close one program then open another.

9. Use anti-aliased text wherever possible to overlay on to a video signal - it will result in a far more stable picture.

10. Always experiment with different Key Level and Keyer settings when overlaying

- there will always be an optimum setting.

44

Appendix B - Troubleshooting

If problems are experienced, please go through these help topics to help you resolve the problem - otherwise see the 'Technical Support' page.

The picture on the video display is black and white

If you are using the S-Video or Composite outputs, then make sure that all these cables are connected correctly. Make sure that the unit is adjusted to the right video standard

PAL/NTSC. Ensure that the color controls on your video monitor are all set correctly.

Selecting the right video standard is vital when overlaying.

There is no picture on my video monitor

If you're using the unit with a laptop computer, you may need to tell the laptop that an external display device is connected. Some laptops automatically detect external video connections, but others will need setting up to do so - often in the form of pressing two keys simultaneously on the keyboard.

If the Green Power LED on the unit is off, ensure that the AC adapter is connected properly. If the LED on the unit is on, then check that the monitor output from the computer is connected to the unit's PC IN connector. Check that the output you are using from the unit is also connected at the unit and the video monitor. Check that your video monitor is switched on and set to the correct input (AUX or A/V selected), also make sure that the brightness and contrast are set correctly.

Check that the FADE button is not flashing - if it is, then the computer video signal is faded out. Press the FADE button once to bring it back again.

The picture on my video monitor is unstable or blank

If the MODE button is illuminated, it means the unit is in Genlock, Overlay or Mix modes, and therefore is expecting a valid video signal on one of the inputs. Check that this is the case, or press the MODE button repeatedly until the light goes out, and you will then be in

PC Out mode.

There is no picture on the computer monitor

Check that the monitor output from the computer is connected to the unit's PC IN connector. Check that your computer monitor is connected to the PC OUT connector on the back of the unit. Check that your computer monitor is turned on and the brightness and contrast levels are set correctly.

The display on the video monitor has a huge border around it

You're almost certainly running the unit with a laptop computer, at a resolution lower than the laptop's own screen. When this happens, the laptop fits the smaller resolution into the larger with a border around the edge. Since the laptop's screen is of a fixed resolution, the only two solutions are: 1) change the resolution you're running at to match the laptop's own internal screen; 2) disable the laptop's own screen, so you just see the image on the video monitor.

45

The unit does not respond to the Infra-red remote control

Ensure that the batteries in the remote control unit are correctly inserted and that they have enough charge left. Make sure that there is no obstruction in front of the unit's Infra-red window.

Ensure that Infra-red control is enabled, as it is possible to disable this in the Advanced menu. Also ensure that you have not 'locked' the unit - see the LOCK button description in the Remote Control section.

There is excessive flicker on the video monitor

Try using a different flicker mode. Turning the contrast down and the brightness up on the video monitor can have a large effect on flicker. Ensure that you are not running an interlaced VGA mode (such as those running at 43Hz).

The video monitor image is distorted

This often occurs where some of the areas of the image are very dark and others are very bright. These extreme changes in the image are difficult for your video monitor to deal with. Try adjusting the contrast and brightness settings on your video monitor to rectify the problem. On some TVs (usually old ones), this effect is unavoidable as they may not be designed with computer images in mind, and therefore show 'bowing' at the sides for some graphic images. The only solution is to adjust the brightness and contrast on your video monitor - the unit is not at fault and cannot correct problems with your video monitor.

If the problem still persists it may be due to the screen size settings, try adjusting the image and its position on the screen.

Some colors come out incorrectly on the video monitor

Try altering the color, contrast and brightness settings on your video monitor. These are usually set up for viewing TV programs which is very different from viewing computer graphics.

If you are using the RGB video output from the unit make sure that the cable is correctly attached to both the unit and the monitor.

If you have altered the brightness value to too high a value, then this may make yellow appear very washed out and even white. In some circumstances, it can cause flashes within solid green areas. Either reduce the brightness setting, or do a Factory Reset to restore the original settings (see earlier in this manual on how to do this).

How can I reduce smearing?

Smearing usually occurs on Composite Video connections, and is generally unavoidable unless you can switch to using S-Video or RGB connections. It occurs because the brightness and color information is transmitted as one signal, and the two parts have to be

'bandwidth-limited' to avoid them interfering with each other. Using good quality video cable will help towards reducing this affect.

S-Video will give far less smearing than composite video.

46

How do I use the unit with a VCR?

Connect one of the unit's video outputs (probably the Composite Video cable) to the

VCR's input. Note that you won't be connecting to the antenna connector on the VCR, but to one of the VCR's auxiliary (AUX) inputs. You have to therefore tell the VCR which input to use - often it's channel 0, or AUX 1, AUX 2, etc.

The recorded image is poor

Standard VHS videos are not very good at recording the fine detail present in computer graphics. S-VHS decks offer much better quality, while professional decks will be even better. Color smearing is usually the first thing that causes a problem, but this is because your video isn't capable of recording the picture in its full resolution - it is not a fault with the unit or your video. Try lowering the computer screen resolution - this will bring the video bandwidth more in-line with the signal that your video is used to dealing with.

The mouse emulation isn't working

Check that the unit is setup for the mouse and not for serial control instead. Check that the infra-red remote control has good batteries installed and that the unit is configured to work from the remote.

If you're using an RS232 sharer cable from TV One, always use it in conjunction with a serial mouse, or your PC probably won't recognize that anything is connected.

If you're using a null-modem RS232 cable (specially made for the unit's 5-pin connector), check that it is connected correctly to both the RS232 port on the back of the Eclipse and to the serial port that the computer uses for the mouse. Re-run the Windows Add New

Hardware function, and it should detect a mouse being present.

Genlocking is unstable

The unit is designed to synchronize itself to a fairly stable reference source. A video player playing a poor quality video tape will not do this and may therefore cause the unit problems. You should also ensure that the correct video standard (PAL or NTSC) is selected on the unit to match the incoming reference signal.

Unit will not lock up to an external source

This may be due to the 'Signal Type' not being set properly. Since the unit needs to know which input to use (composite or S-video), it is vital to set this properly.

I get random colors on screen when overlaying or mixing

This means that the unit cannot 'lock' to the video source's subcarrier frequency. If there is no way to correct this on the video source, see the description in Appendix C of the subcarrier frequency adjustment.

These adjustments are factory set before supply and should not need to be altered - it is not advisable to adjust these without proper measurement equipment to correctly set the internal frequencies.

Under rare circumstances, it may be necessary to adjust these to maintain a color lock to a video source. This should only be necessary where the video source's subcarrier frequency is outside the lock-range of the unit.

It is a good idea to display a color bar image or an image with lots of different colors in it on your computer while making this adjustment (especially for NTSC). Using a preset adjustment tool, adjust the desired clock preset until the displayed colors are correct.
