1.0Introduction
Todaysinformationtechnologiesdevelopmenthasincreasedtheimportance
ofdata security. Itisaresult of thegrowinginformationefficiencyandeasy
onlineaccess tothedata.IntelligentKVM switchE320isafirstdevice of
itskindwhichcanprotectdata againsttheftordamage.Theprotectionlevel
isABSOLUTE!
1.1Switchapplication
E320 allowstohandletwoseparatecomputersystems(computersor
computernetworks)inoneworkplace (display,keyboard andmouse),
withoutanypossibilityof data exchangebetweenthesetwosystems. Soone

secondcanoperatewithsecretdata.Bothcomputersmustbeequippedwith
DVIorHDMIvideooutput.
2.0PrinciplesofOperation
Aprincipleof theintelligentKVM switchE320 hasbeenbasedonapatent
validinEuropeanUnion, USA and Russia.
Twooutputvideosignalsfromtwocomputershavebeenmergedintoone
videooutput.OnmouseclickE320canrecognizetowhichsystemthe
mouseandkeyboardhavetobeswitchedon.Afixbackgroundcoloris
necessaryforthecorrectfunction.
All thesignaltransfersbetweenE320 andsystemsarestrictlyunidirectional,
sothereisnotpossibilitytosendanydata fromonecomputertosecondone
through E320.
Duetothephysicalprinciplesoftheone-waydata transfers
thesecurityofE320isABSOLUTE!
2.1HWrequirements
