1832system,apairofMD‐3deviceswilltranslatedthiscontrolprotocolintoTTLdataforinputto/outputofthe
‘Control’connectorontheVRK‐1832.

GettingStarted
InitialInspection
Immediatelyuponreceipt,inspecttheshippingcontainerfordamage.Thecontainershouldberetaineduntil
theshipmenthasbeencheckedforcompletenessandtheequipmenthasbeencheckedmechanicallyand
electrically.Iftheshipmentisincomplete,ifthereismechanicaldamage,oriftheunitfailstooperatenotify
FiberPlexandmaketheshippingmaterialsavailableforthecarrier'sinspection.
ChassisMounting
Mountthechassisusingfastenersappropriatetoyourstandard19”rackenclosure.Allfour(4)mounting
pointsMUSTbeutilized.Ensurethatthereexistsadequateclearanceforfrontandrearventilation.Thechassis
shouldbelocatedinanenvironmentwhereanambienttemperaturebetween0°and50°Ccanbemaintained.
IfusingtheVIS‐1832configuration,placetheStageBoxinalocationcentraltothemajorityofyoursignal
sources.
MakingConnections
Thesetupofabasic1832systemisaquickandsimpleprocess.
ConnectaFiberCablebetweentheprimaryfiberconnectionoftheVRK‐1832andtheprimaryfiberconnectionof
theTailEnddevice(VIM‐1832orVIM‐MY32M)
Makecopperconnectionsatbothends
ConnectACpowerviatheNeutrik™powerCONTRUE1connector
Verifythe‘Sync’lightonboththeHeadandTailunitsaregreen
ThemoreadvancedfunctionsoftheLightViper™VRK‐1832areaddressedlaterinthismanual.

NOTE:thesignalcomingoutofaTailunitintotheconsolewillbelinelevel.Whenthegain
switchesontheVRK‐1832areproperlyset,thesignalgoingintotheconsolewillbeveryhotthis
isnormal.Uselinelevelinputsorengageinputpadstoachieveoptimalsignal‐to‐noiseratio.



What’sthedifferencebetweenaVRK‐1832andaVIS‐1832
Functionally,theVRK‐1832andVIS‐1832areidentical.Theonlydifferenceisthepackaging.
VRK‐1832
TheVRK‐1832iscasedina17”5Urackpackage.Itisdesignedforexclusiverackmountingapplications.The
power,fuseandcontrolconnectionsarelocatedontherearor‘insidetherack’surface.Theoptical
connectionscanbemountedeitheronthefrontsurfacealongwiththeaudioconnectionsorontherearof
theunitbesidethepowerandcontrolconnectors.Frontinstallationwouldberecommendedfortacticaland
portablesolutions.WhenorderingaVRK‐1832withopticalCONconnectorsthisisthedefaultmountingofthe
opticalconnectors.
Optionally,theopticalconnectorscanberoutedtotherearsurfaceforconnectioninsideoftherack.When
orderingaVRK‐1832withstandardLCinstallationconnectors,thisisthedefaultconfiguration.Thisprovides
protectionforinstallationfiberinsidetherackenclosure.

Figure1VRK‐1832shownwithbothopticalmountingoptions
VIS‐1832
TheVIS‐1832isdesignedtoemulatethefunctionalityofatraditional‘floorbox’.Itsdurablesteelhousinghas
rubberfeetonthebottomandissufficientweighttopreventcablesfrompullingtheboxover.Power,fuse,
controlandallfiberconnectionsareonthesideoftheunit.OnlytacticalopticalCONconnectorsare
recommendedfortheVIS‐1832.InstallationgradeLCfiberandconnectorscouldbevulnerableinanexposed
‘floorbox’application.
