2.3 INSTALLATIONINSTRUCTIONS

MMUIIisdesignedtobeinstalledinacockpitenvironmentsecuredtoDzusrails.A
suitablelocationshouldbefoundthatwillprovideenoughdepthinthepanelforthe
unitplustheconnectorswithamblebendradiusforthewiringharness.Failureto
dosomaydamagetheharnessandcauseamalfunctionofthesystem.

2.3.1 ELECTRICALINSTALLATION

Followtheinstallationdrawingintheappendixofthismanualasarecommended
methodtointerfacingtheMMUIItoaPOTSorRS‐232connection.Completelyread
thenotesprovided.

2.3.1.1POTSWIRING

Thisisa600Ohmtip/ringSubscriberLineInterfaceCircuit.

Theringingvoltageandcurrentisdependedonthenumberofringerloads.
ThePOTSspecusedcallsfor;

Theringingsignalisgeneratedbyswitchingthetransceiverintoringing
mode.Ringingvoltageofapproximately65Vrmsisappliedtoasingle
handset.DuringringingtheintegralDC/DCconverterautomatically
switchestoproduceabatteryvoltageof‐72V.Thiswillproducegreaterthan
40Vrmsintoaringloadof3.Theringingwaveformissetinternallytogive
thecorrectwaveformwith20Hzto25Hzringingfrequency.

Soringingisprovidedbyourtransceiverata20Hzcadenceandaring
voltageofgreaterthan40Vrmswith3ringerloads.

2.3.1.2InputsandOutputs

2.3.1.2.1 Outputs
Fourdiscretelampoutputsdesignedtoilluminatethelampsusedfor
IncomingMessageandthePhonelamps.Twonotusedatthistime.Phone
audiooutputat500Ωimpedancethatprovidesnominal5.0VACRMSaudioto
theheadsetsoraudiopanel.

2.3.1.2.2 Inputs
Microphoneaudioat150Ωimpedance.4VACthatconnectstotheheadsetsor
audiopanel.

3 OPERATION

ThefollowingwillcoveroperationissuesontheMMUII.SeetheMMUIIOperator’s
GuideforacompletedescriptionofhowtooperatetheMMUII.

TheMMUIIiscomputercontrolleddialerandveryflexibleinoperation.It
communicatestothetransceiveroveranRS‐232portorPOTSline.

Thisunitcanbeprogrammedintheaircraftwithnewmessagesets.Ithasaneight
stepdimmingfeaturetothedisplay.

TheMMUIIhas32Kofinternalmemory.Thisisenoughstoragefor1000phone
numbers/textmessagesifallthescreencharactersweretobefilled.

TheMMUIIprovidesauserinterfacetoanexternaltransceiver,allowingauserto
controlvoicecallsandsend&receivetextSBDmessages.TheMMUIIcontainsa2‐
line,16characteralphanumericdisplayandarotaryknobwithapushbuttonaction.
ExternalI/OincludesanRS232port,andtwolampdrivers.

TheMMUIIisloadedwitha“MessageSet”,whichissavedinFlashmemory.The
MessageSetcontainsconfigurationdata,thenamesandphonenumberchoicesfor
voicedialing,andthecompletesetoftextmessagesthatcanbeselectedbytheuser
fortransmissiontotheground.

TheMessageSetmaybeloadedonthegroundviatheMMU’sRS232port.

TheMMUIIcommunicateswiththemapapplicationviabinarySBDmessages.
MobileTerminated(“MT”)messagesaresentfromthegroundtotheMMUII
(uplink),andMobileOriginated(“MO”)messagesaresentfromtheMMUIItothe
ground(downlink).ThesemessagesaresenttoandfromtheSkyConnectTracker
Map.Atreleaseofthistext,noothermappingsystemhastheabilitytomakeuseof
textmessagingtoorfromtheaircraft.

MSETManage‐PhonenumbersandmessagesarecreatedfortheMMUIIbyusinga
SkyConnectprogramcalledMSETManage.Thisprogramwillcreateamessageset
ofphonenumbersandcannedmessagestobeloadedintotheMMUIIviaRS‐232
connectionorWi‐Ficonnection.Aconnectorshouldbeinstalledasclosetotheback
oftheMMUIIaspractical,toallowtheRS‐232portbetweenthetransceiverandthe
MMUIItobebroken,andallowtheconnectionofaPCforthispurpose.


incoming.
ApopularexampleofacannedmessagetheMMUIIcansendisaflightplan.FPdata
cancontain;TO/FROMwaypoints,ETA,NumberofPAX,andFuelonBoard.

TheMMUIIcancontrolthevolumeoftheLBTthroughitsserialport.TheMMUII
hasasignalstrengthindicatoraspartofitsfunctions.

ThereisanoptionalWi‐FiinterfacetoallowthecommunicationwiththeMMUII
fromaPCwirelesstoprovidetextmessagingovertheMMUIIwithoutawired
connection.TheWi‐FiconnectioncanalsoservetoprogramtheMMUIIwithoutthe
useofacable.
