settings.for.all.items...
Note: Before using the 'Calibrate All' option, if possible, remove on-screen
display (OSD) elements generated by the AdderView CATxIP 1000 (such as
a host name label or menu). These OSD elements use different video rates
to those of the host system(s) and can affect the setting of the automatic
threshold value. AdderView CATxIP 1000 uses an improved calculation
procedure to filter out the effect of these elements. However, best results
are obtained when the screen contains only host system information.
Note: To maximise performance, the threshold level is automatically
increased by 50% when a slow link is detected.
Note: When the AdderView CATxIP 1000 is used with one or more other
switches, the threshold needs to be higher than 32 due to the significant
amounts of 'noise' that these switches introduce. The AdderView CATxIP
1000 configuration should detect such noise and adjust the threshold
accordingly. .
Setting the Threshold manually
Occasionally.it.can.be.useful.to.manually.adjust.the.Threshold.setting,.in.order.to.
achieve.a.setting.that.best.suits.your.particular.requirements..
1. Use.the.'Calibrate.All'.function.to.ensure.that.all.other.settings.are.
optimised.
2. Click.the.Threshold.left.arrow.button.to.decrement.the.setting.by.one.and.
observe.the.'Display.Activity'.indicator..
3. Repeat.step.2.until.the.Display.Activity.indicator.suddenly.rises.to.a.much.
higher.level.(i.e..50%)..This.will.mean.that.you.have.reached.the.noise.
boundary..At.this.point,.increment.the.Threshold.value.by.2.or.3.points.to.
