UNDERSTANDINGTHERFMODULECABLES
BeforeyouinstalltheRFModulecables,familiarizeyourselfwiththerulesthatpertaintothesecables,asdefined
inthefollowingsections.
AlwaysprovidedateachRFModuleshelfarefivecables:
• twoHigh‐SpeedDataCables,whichinthisdocumentarereferredtoasLVDS(Low‐VoltageDifferential
Signaling)cables
• twoRFCables(TX0/RX0)and(TX1/RX1)
• onePower(PWR)Cable.
PowerCableConnection
Maintainadequatestrainreliefdistancesfromtheconnectionpointstothemodule.
LVDSCableConnections
• LVDScableslabeledPRIMandDIVshouldalwayseitherbeconnectedtoaRFModuleorstrainrelievedto
adjacentcables,asthisprotectsthecableagainstdamagethroughmisplacement.
• AlignandfullyinserttheLVDScableconnectorsintotheirrespectiveconnectorcages.Fullinsertionis
identifiedbyanaudibleclick.
• EnsurethetwoLVDScablesarefullyseatedandlatchedintotheirrespectivereceptaclesontheRFModule
bylightlypullingoutwardontheconnectors.Iffullyseatedandlockedintoposition,thecableconnectorswill
notslidebackout.
• Maintainadequatestrain‐reliefdistancesfromtheconnectionpointstotheRFModule.
RFCableConnections
TheRFModulecablesthatarepre‐installedinthePRUconnecttothecorrespondingconnectorsontheRF
Module.TheRFModulecablescorrelatetotheantennaconnectorsonthebottomofthePRUchassis.
RFCableRules
• WheninstallingaDiversity,MIMOorDual‐BandRFModule,bothRFcableslabeledMODNTX0/RX0and
MODNTX1/RX1shallbeconnectedtotheN‐StyleconnectionsoftheRFModule”
NOTE: Olderlabelingschemesused“PRI”and“DIV”.Tomatcholdlabelingschemestocurrentlabeling:
• TX0/RX0=PRI
• TX1/RX1=DIV
• WheninstallingaNon‐DiversityorSISORFModule,oranSMR800/900Dual‐BandDual‐BayRFModule:
– TheMODNTX0/RX0cableshallbeconnectedtothesingleavailableN‐StyleRFConnectionoftheRF
Module.
– TheMODNTX1/RX1cableshallbeconstrainedtotheexistingcablesusingatiewraporsimilarly
acceptedfastenersoitcannotbepinchedorpreventthePRUdoorfromclosing.Donotcutorattemptto
otherwiseremovethisRFCable.
