INSTALLATIONAND OPERATING MANUAL
Congratulationsonyourpurchaseofthemostadvanced combinationdelaybox/timerunitavailablefor
today’sprecisiondrag racing.The PRO-CUBE Òhasbeendesigned togive youunprecedented controlof
yourreactiontimeandETwithahostofstandardfeatures,plusoptionsforup tothree generalpurpose
timers,all inonesuper-compactunitthatcanbemounted almostanywhere. Theprecisionavailablewith
thesetimersmakesthemperfectforcontrollingavarietyofequipmentincludingthrottlestops,shifters,and
multi-stagenitroussystems.Youshouldreadandunderstandthisentiremanual,includingthewarranty
sectionbeginningonpage8,beforeproceedingwithinstallation.
STANDARDFEATURES
Cross-Over:Allowsyoutoreleasethetransbrakeswitchonaslower opponent’stopbulb onafull
opentree. Thedelaytimeis automatically calculated fromdial-inanddelayvalues youenter.
SecondHit:Youcanenteraseparatedelayforhittingthetree asecondtime. It’sthesameas
havingtwo delayboxesinone. Thisfeatureallowsyoutotaketwo shotsatthetree inlongcross-
oversituations.Youwill launchonthefasterofthetwo reactions.
Bump-Down Ò:Thispowerful featureallowsyoutoimprove latereactionsby subtractingdelaytime
after releasingthetransbrakeswitch.Youcanprogramtheamountoftimetosubtract,youcan
bump-downany numberoftimes,andyoucanuseitforeitheroneorbothhitsonthetree. In
addition,thisfeaturecanbeused onTimer1duringtherun.Ifyouhave athrottlestopconnected to
Timer1,theBump-Downfeaturewill allow youtocorrectfortrackconditionssuchastirespinby
reducingthestoptime.
FlinchProtection Ò:Two differentmethodsareprovided forpreventingred-lightdisqualificationwhenyou
releasethetransbrakeswitchbeforethetree starts.
Run Info: Ifyouuseeitherthesecondhitorthe Bump-DownÒfeature, informationwill
automatically bedisplayed toindicatethedifference inyourreactiontimesfordouble-hits,aswell as

younotused thesepowerful features.
TransbrakeOutput:Highcurrentoutputforuseonall typesoftransmissionbrake, footbrake, andclutch
releasesolenoids.Handles up to25 ampload.
LineLockOutput:Thisoutputisactivated andreleased simultaneously withthetransbrakeoutputbut

INITIALSETUP
Singlevs DualTrigger Interface Mode:
The PRO-CUBE Òallowsyouto“hit”thetree twiceand launchyourvehicleonthequickeroftwo
reactions.Ifyouwanttotakeadvantageofthisdouble-hitcapability,youhave theoptionofusingtwo
separatetrigger(transbrake)switchesorasingleswitch.Ifyouchoosenottousethedouble-hitcapability,
youonly need onetransbraketriggerswitchconnected tothe TRIGGER1 terminal.
SelecteitherSingleorDualtriggerinterfacemode usingany right-side ADJswitch.
Theamountofcross-overtimeyouhave betweenthefirstandsecondhitwill determine
whetherit’sbesttouseoneswitchortwo. UsingSingleTriggermode tohitbothtopbulbs is
generally notrecommended unless you’reatleast1.5secondsfasterthanyouropponent.
Hittingbothtopbulbswithtwo separateswitchesinDualTriggermode doesn’trequireas
muchcross-overtime. InDualTriggermode, TRIGGER1 isalwaysused forthefirsthit,and TRIGGER2
forthesecondhit.InSingleTriggermode, TRIGGER2 is ignored.
Anotherimportantdifferencebetweenthesetwo modesinvolvesthe FlinchProtection Òfeature.
Simply stated, flinchprotectioncanpreventyoufromred-lightingwhenyouaccidentally releasethetrigger
switchbeforethetree starts.IfthisoccursusingDualTriggermode, justpress thesametriggerswitchagain
andthedelaythatwasstarted unintentionally will bereset.Thedelaywill berestarted whenthetrigger
switchisreleased. InSingleTriggermode, however,thedelayisnotresetby pressingtheswitchagain.In
thismode aknownred-lightsituationcanonly beprevented by pressingandholding the TRIGGER1 switch
untilthebottomofyourtree. Yourvehiclewill launchinstantly whenthetriggerswitchis released.
Timer OutputConfiguration:
Exceptforthe3timerversion,Timer1isa4-stageoutputthatcanbecycled onandoff twice. Ifyou
wanttocyclethistimeronandoff justonce, useeitherpairofsettingsandsettheotherpairto0.Inthe3
timerversionall three timershave 2-stageoutputsthatcanbecycled onandoff onceeach.
Forcompatibilitywithall typesofequipment,Timers1and2canbeconfigured foreither
“normally off”or“normally on”mode. Timer3,however,is fixed in“normally off”mode for
mostcommonequipmentandcannotbechanged. Configurethetimersasrequired foryour
equipmentusingthefrontpanelswitches.
Notethatthefirston/off cycleofTimer1isadjustablein0.001 (onethousandth)secondincrements
forveryprecisecontrol.Timers2and3andthesecondon/off cycleofTimer1areadjustablein0.01 (one
hundredth)secondincrementsforextended down-trackrange(up to39.99 seconds).Notethedecimalpoint

subtracttimefromstages2&4of TIMER1.Programtheamountoftimeyouwantsubtracted fromthe
