To use skew adjustment

1Display a skew pattern on the appropriate computer. You can either use the supplied skew pattern or create your own:

Using the supplied skew pattern

iInsert the supplied Adder Installation CD-ROM into the CD player of the computer.

iiWithin Windows, use the My Computer option (usually available as a desktop icon or within the Start menu) to view the contents of the CD-ROM. Double-click the Skew entry to display the standard

test pattern. If necessary, maximise the application window so that the image fills the screen.

The screen will show a series of fine red, green and blue crosses which should all be

in line, vertically and horizontally. Skew affects the horizontal placement of the colours and using this pattern it is much easier to discover which, if any, colours are being adversely affected by the cable link.

Creating a skew test pattern

iRun any image creation/editing application, such as the Paint program supplied with Windows.

iiUsing the image application create three

stacked horizontal rectangles (one red, one green and one blue) that fill the width of the screen.

iiiDraw a vertical black line down across the coloured bars and then repeat this vertical line at intervals along the width of the coloured bars. These lines create breaks across the colours and give you more opportunities to view the horizontal position of each colour relative to the others.

2 On the remote user keyboard (connected to an Adder X100AS/R or
X200AS/R extender), simultaneously, press the hotkeys (by default,		and
) along with	to enter configuration
mode.

The three keyboard indicators (‘Num Lock’, ‘Caps Lock’ and ‘Scroll Lock’) will now begin to flash in sequence.

Exit image controls and save settings

Retard colour timing

5 When the selected colour crosses (or colour bars) are correctly positioned, press to exit that colour channel. The keyboard indicators will return to flashing in sequence.

6If required, repeat steps 3 to 5 to select and adjust any colour channel until the vertical lines of the red, green and blue crosses are all aligned.

7 When all colours are correctly aligned on all video channels, press	to exit
configuration mode and permanently save all settings.

Note: Once you have made the skew adjustments, it may be necessary to re-adjust the image controls to attain optimum screen images.
