Video compensation
The.AdderView.CATx.units.allow.computer.systems.to.be.placed.up.to.50m.
(160.feet).away.and.remote.users.to.be.extended.by.a.maximum.of.300m.(980.
feet)..Such.long.cable.lengths.can.affect.video.signals,.especially.when.higher.
screen.resolutions.are.used..In.order.to.eliminate.any.video.signal.degradation,.
all.AdderView.CATx.units.and.accompanying.Adder.X100.and.X200.extenders.
provide.effective.software-based.video.compensation.features..
Two.main.types.of.video.compensation.are.provided.within.the.AdderView.CATx.
installation,.these.are:
•. Computer video compensation.-.operates.on.video.signals.between.each.
computer.system.and.the.AdderView.CATx.unit..See.
Computer video
compensation .
•. Remote user video compensation.-.operates.on.video.signals.between.
each.remote.user(s).and.the.AdderView.CATx.unit..See.
Remote user video
compensation .for.details.
It.is.important.to.note.that,.providing.the.cabling.arrangements.do.not.change,.
the.various.video.compensations.need.to.be.applied.only.once.to.each.computer.
or.remote.user.link..During.operation,.control.of.video.compensation.is.fully.
automatic..Please.take.into.account.the.following.when.configuring.links:
•. The.AdderView.CATx.stores.a.video.compensation.setting.for.each.
computer.which.defines.the.level.of.compensation.that.is.applied.whenever.
the.computer.is.selected..This.“computer.video.compensation”.setting.
is.to.correct.for.any.video.clarity.loss.due.to.the.CATx.cable.between.the.
AdderView.CATx.unit.and.the.computer’s.CAM..
•. CATx.cables.below.10m.give.very.little.loss.and.so.it.is.not.normally.
necessary.to.be.concerned.about.setting.any.computer.video.compensation.
if.short.CATx.cables.are.being.used.between.the.AdderView.CATx.and.the.
CAM.for.each.computer..
•. “Computer.video.compensation”.may.be.setup.by.typing.in.the.cable.
distance.in.the.OSD.or,.if.very.fine.video.adjustment.is.desired,.by.observing.
the.video.picture.on.the.local.(user.1).port.whilst.making.adjustments..
•. If.a.cascade.of.switches.is.being.used,.computer.video.compensation.only.
needs.to.be.applied.at.the.master.AdderView.CATx..
•. “Remote.user.video.compensation”.compensates.for.any.CATx.cable.losses.
introduced.by.the.cable.between.the.X100/X200.and.the.AdderView.CATx..
The.required.video.compensation.setting.does.not.vary.as.any.“computer.
video.compensation”.is.automatically.added.as.different.computers.are.
selected..This.only.needs.to.be.setup.once.during.installation..
Note: For installations where both computers and remote users require video
compensation, always ensure that the computers are compensated first.
•. A.third.type.of.video.compensation.is.provided.by.Adder.X100AS/R.and.
Adder.X200AS/R.extender.modules.only..This.type.of.compensation.is.called.
Skew.adjustment.and.combats.the.effect.of.uneven.twisted.pairs.within.link.
