ItsetsuptheTripinputpriority,tonecontrolfrequencyandvariousotherfeatures.

ExplanationofINITfilecontents
/Test= 0 NotYetUsed
/Debounce=5; Debouncetimein10mSincrements
Thiscommandconfiguresthetimethatthetripinputshavetobevalidandstablebefore
theDMS6000willrespond.Avalueof5meansthetriphastovalidfor50mS.
Youmaysetanyvaluefrom1to500(10mSto5000mS)
Thiscannormallybeleftat5butifaparticularlyelectricallynoisyenvironmentiscausing
falsetriggers,thenraisethisvaluetotryandfixtheproblemorifthetriggerpulseisvery
short,tryreducingthisvalue.

/Invert=00000000; Inverttrips
Thiscommandallowsyoutoinverttheoperationofanyorallofthetripinputssothatthe
tripisactivewhenthetriplineisopen.
Forexample:
/Invert=10000000;  Trip1isinverted.Message1playswhenTrip1is
inactive.
TheaboveexamplecouldbeusedwhentheDMS6000isconnectedtoastandardPIR
sensorwhichhasanormallyclosedcontactoutputthatopenswhenthePIRdetectsmove-
ment.
Thenumbersfollowingthe‘=’signcanonlybe‘1’or‘0’
Trip1isthefirstdigit,Trip2istheseconddigitetc
SoforexampleifIwishtoinverttrips3&4,Iwouldsetthecommandasfollows:
/Invert=00110000; Trips3&4inverted
/Oneshot =00000000; Edgetriggeredtrips
Thiscommandconfiguresthetripinputsindividuallytoallowoneshotoredgetriggering.
OneshottriggeringisusedtopreventatrackplayingcontinuouslyeveniftheTripremains
activeattheendofthesoundtrack.
Tore-triggerthetrack,theTripmustbereleasedandthenre-appliedafterthesoundtrack
hasfinishedplaying.
Thiswouldnormallybeusedwhentriggeringfromacontactthatremainsclosedforlonger
thanthesoundtracksuchascertainPIRsensorsandtimerswitches.
Forexample:
/Oneshot =10000000; Trip1isoneshotenabled
Thenumbersfollowingthe‘=’signcanonlybe‘1’or‘0’
Trip1isthefirstdigit,Trip2istheseconddigitetc
SoforexampleIwishtooneshottrips1,4&7,Iwouldsetthecommandasfollows:
/Oneshot=10010010; Trips1,4&7oneshotenabled

/Interrupt=0;  Tripinterruptmode
ThiscommandconfigureshowtheDMS6000respondswhenanothertripcomesinwhile
playing.
Thefouroptionsare:
/Interrupt=0;  Nointerrupt
Whileafileisplaying,alltripsareignored.
/Interrupt=1;  Priorityinterrupt
Whileafileisplaying,tripsofalowervaluewillbeacceptedandthecurrentfilewillbe
cancelled.
/Interrupt=2;  Anyotherinterrupt
Whileafileisplaying,anyothertripwillbeacceptedandthecurrentfilewillbecancelled.
Iftwotripsareactiveatthesametime,thelowestonewilltakepriority.
/Interrupt=3;  Anyandselfinterrupt
Whileafileisplaying,anyothertripwillbeacceptedandthecurrentfilewillbecancelled.
Ifthesametripisreleasedandthenre-applied,thefilewillberestartedfromthe
beginning.
Iftwotripsareactiveatthesametime,thelowestonewilltakepriority.
Moreoptionsmaybecomeavailableinthefuture.
/Binary=0;  Binarycodedtrips
Settingthiscommandto‘1’willallowaccessto255audioorcommandfilesbyapplying
theappropriatebinarycodenumberontothetripinputsandthenapplyingtheactivelow
start signal.
/binary=0;  uptoeightfilescanbeaccessedwiththe8triplines
/binary=1;  upto255filescanbeaccessedusingbinarycodes
Binaryequivalentvalueforeachtripinput.
Trip1=1, Trip2=2, Trip3=4, Trip4=8,
Trip5=16, Trip6=32, Trip7=64, Trip8=128.
Example.
Toaccessfile‘043name.mp3’youmustactivatetrips1,2,4,&6thenapplyanactive
LOWtothestartPin.
Thisequatesto 1+2+8+32=43
TheSTARTlinecanbeheldlowifthetripsforthebinarycodeareappliedatthesame
time,iefromalogicboardordiodematrix.
