Remote user skew adjustment
The.category.5,.5e.and.6.cabling.supported.by.the.AdderView.CATx.consists.of.
four.pairs.of.wires.per.cable..Three.of.these.pairs.are.used.to.convey.red,.green.
and.blue.video.signals.to.the.remote.video.monitor..Due.to.the.slight.difference.in.
twist.rate.between.these.three.pairs,.the.
red,.green.and.blue.video.signals.may.not.
arrive.at.precisely.the.same.time..This.is.
visible.as.separate.colour.shadows.on.high.
contrast.screen.images.and.is.particularly.
apparent.when.using.higher.screen.
resolutions.and.some.types.of.category.5e.
cables.
To.alleviate.this.situation,.the.Adder.
X100AS/R.and.X200AS/R.modules.
provide.internal.skew.adjustment.that.
can.help.to.rectify.the.situation..The.
skew.adjustment.works.by.delaying.or.
advancing.the.timing.of.any.of.the.red,.
green.or.blue.colour.signals.so.that.they.
are.all.delivered.to.the.monitor.at.precisely.the.same.time..For.best.results,.the.
“skew”.program.supplied.on.the.disk.or.downloadable.from.

To use skew adjustment
1. Display.a.skew.pattern.on.the.appropriate.computer..You.can.either.use.the.
supplied.skew.pattern.or.create.your.own:
Using the supplied skew pattern
i. Insert.the.supplied.Adder.Installation.CD-ROM.into.the.CD.player.of.the.
computer.
ii. Within.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.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
i. Run.any.image.creation/editing.application,.such.as.the.Paint.program.
supplied.with.Windows.
ii. Using.the.image.application.create.three.
stacked.horizontal.rectangles.(one.red,.
one.green.and.one.blue).that.fill.the.
width.of.the.screen.
one.green.and.one.blue).that.fill.the.
width.of.the.screen.
iii. Draw.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.extender),.
simultaneously,.press.the.hotkeys.(by.default,.

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