DEVICEDATAPAGE—DST810SMARTTRIDUCER
Onceconnectedtoyourdevice,theCASTappwilldisplaythedata
availablefromthedevice.TheDST810willdisplayDepth(below
transducer),Speed(speedthroughwater),andTemperature(water
temperature).Asingletapanywhereonthescreenwillchangetheview
fromgraphictotext.
Bydefault,attitude(heelandtrim)outputisturnedoff.
Adatafieldthatdisplays“‐“iseitherdisabledorisnotreturningavalid
value.IfDepthdoesnotdisplayanumber,ensuretheurethanefaceof
thesensorisincontactwiththewater.Ifthewaterdepthisgreaterthan
themaximumrangeofthesensor,nodepthwillbereturnedand“‐“will
bedisplayed.
Thespeedometerviewwillshowaninitialrangeof0–15kn(thisrange
willbeadjustedbasedontheunitsselected).Asthespeedincreases,the
rangeofthespeedometerwillautomaticallyadjusttoensurethespeedis
alwayseasilyreadable.
Note:Ifapositivedepthoffsethasbeensavedtothesensor,theCAST
appwilldisplay“DepthBelowSurface.”Iftheoffsetsavedhasanegative
value,theCASTappwilldisplay“DepthBelowKeel.”SeetheOffsets
sectiononpage10formoreinformation.

NMEA2000®PAGE
TheNMEA2000pagedisplaysallthePGNstheconnecteddeviceis
capableofsupplyingtothenetwork.
Bydefault,eachitemwilldisplaythenameofthePGNandtheNMEA
2000PGNnumber.IfthePGNisdisabled,“Off”isdisplayed.IfthePGNis
enabled,theoutputratewillbedisplayed.







OutputratesareshownasanumberofPGNsperunittime.Forexample,
iftheWaterDepth(128267)PGNdisplays“1/sec,”thePGNisenabled
andwillbeoutputtothenetworkonetimeeachsecond.If“2/min”is
displayed,thePGNwillbeoutputtothenetworktwotimesperminute,
oronceevery30seconds.
Usethe“arrow”buttonontherightsideofeachitemtoexpanditand
enable/disableoradjusttheoutputrate.
TheswitchatleftwillenableordisablethePGNoutput.
ThedropdownmenuatrightwillallowyoutoadjustthePGNoutput
rate.
Note:ChangingthePGNoutputoroutputratewillnotchangethe
internaldatacalculationrate.


9

DisablingaPGNusingtheswitchwillpreventdatafrombeingsenttothe
network,butitwillnotpreventthesensorfromcalculatingavalue
internally.
Forexample,disablingtheDepth(128267)PGNwillpreventdepth
informationfrombeingprovidedtothenetwork,butitwillnotstopthe
sensorfrompingingfordepth.



OFFSETSPAGE
OffsetscanbeprogrammedforDepth,Temperature,andTrim,andHeel.
Anoffsetisanadditivevalue.Settinganoffsetwilladdto(orsubtract
fromiftheoffsetisnegative)thevaluemeasuredbythesensor.The
unadjustedvaluemeasuredbythesensorislistedas“Raw.”Tapthe
underlined“Offset”valuetoadjusttheoffset.Enteranegativevalueto
subtractfromtherawvalueorapositivenumbertoadd.
Forexample,ifthekeelextends1footdeeperthanthefaceofthe
transducer,enteravalueof‐1asadepthoffsettodisplay“DepthBelow
Keel.”1willbesubtractedfromeverydepthmeasurementtakenbythe
sensorbeforeitissenttothenetwork.Everydeviceonthenetworkwill
seetheadjusteddepthbelowkeel.
Temperatureoffsetsworksimilarlytodepthoffsets.


Heelandtrimcanbecalibratedusinganoffsetaswell.Theoffsetin
degreesisaddedtotherawvaluefromthesensor.
Ifnooffsetshavebeenprogrammed(0degreesforbothheelandtrim),
theappwillpromptyoutocalibratethesensor.Thiscanbedoneinone
oftwoways.”
Toautomaticallycalibrateheelandtrim,makesuretheboatisrelatively
stationary.Pressandholdthecirclemarked“HoldtoCalibrate.”Theapp
willbegintocalculateanaveragepitchandrollreadingover10seconds
andanorangebarwilldisplaytheprogress.Oncethebarflashesgreen,
theaveragereadingforbothheelandtrimwillautomaticallypopulate
theoffsetfieldsandthesensorshouldreadapproximately0degrees
under“Value”forbothheelandtrim.Remember,thecalculationusesan
average,soanymovementoverthemeasurementperiodwillimpactthe
finalnumber.
Alternatively,thevaluescanbemanuallyprogrammed.Forexample,if
therawheelvalueis17.8degrees,enteringanoffsetof‐17.8willresult
inareportedvalueof0degrees.


11

SPEEDCALIBRATION
Unlikeoffsets,whichareadditive,basicspeedcompensationvaluesare
enteredaspercentagesandaremultiplicative.A10%speed
compensationwillresultina10%increaseinthereportedspeedacross
allvalues.
Forexample,a10%speedcompensationwillresultinanoutputof11kn
(+1kn)whenthepaddlewheelmeasuresarawvalueof10knandan
outputof22kn(+2kn)whentherawmeasuredvalueis20kn.
Thewaterflowprofileunderthehullofyourboathasalargeaffecton
thereadingofthespeedsensor.Manyvariables,includingtheshapeof
thehull,theroughnessofthesurface,thepositionofstrakes,etc.will
changetheattachedflowprofile.Seethetransducer’sinstallationguide
forinformationonwheretoinstallthesensorinthehulltoensure
accuratespeedanddepthperformance.Evenwhenthesensoris
correctlyinstalled,it’simportanttocalibrateyourpaddlewheelatits
installationlocationandundernormalusetomakesureitdeliversthe
bestpossibleperformance.
Calibratingspeedbytravelingaknowndistanceisacommonmethodof
calibration,butthestartandendpointsaretypicallyfixedtotheground
andasinglerundoesnottakeintoaccountthemovementofthewater
current.
CalibratingdirectlytorawGPSspeedovergroundcanalsoresultinan
inaccuratecalibration.Iftheboatistravelingina3kncurrentinthe
directionofmovement,theGPSSOGwillbe3knfasterthantheactual
speedthroughwater.
TheAirmarCASTappallowsyoutoquicklycalibratespeedandcorrectfor
current.Youcanalsocorrectthespeedcalibrationforchangesintheflow
beneaththehullthatoccurwhentheboatisheeledovertoonesideor
theother.
ThereareseveralmethodsofspeedcalibrationusingtheCASTapp.


12

BASICSPEEDCORRECTION
Thesimplestwaytocalibratespeedisasinglepointpercentageoffset.
Thistypeofcalibrationappliesafixedpercentagecorrectiontoevery
readingfromthepaddlewheel.
NavigatetotheSpeedCalibrationtab.Bydefault,thespeedcalibrationis
setto“OFF.”
Enablethe“BASIC”speedcalibration.
Ifthedesiredpercentageadjustmentisknown,youcansimplyenterit
intotheCompensationfield.
Ifyouwouldliketheapptocalculatethecorrectpercentageadjustment
foryou,tapthewizardicon.


CASTappcancalculatethepercentageusingoneoftwomethods.
 SOG:SpeedthroughwateriscalculatedusingaGPSreference
speedoverground.
 Distance:Speedthroughwateriscalculatedusingtraveltime
overaknowndistancesuchasameasuredmile.

SOGMETHOD
TheSOGmethodallowstheapptocalculateyouraveragespeedover
groundusingtheinternalGPSinyoursmartdevice.Youcanalso
manuallyenteranaveragevaluefromanexternalsource.
Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant
thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach
boat.
Oncetravelingatarelativelyconstantspeedanddirection,tapthe
“Primary”button.Theappwillcountdownasitcalculatesanaverage
indicatedspeedfromthepaddlewheelandanaverageGPSSOG.


13

Oncecomplete,theaverageforeachvaluewillbeshownandthe
“Primary”buttonwillchangeto“Reverse.”
Turntheboat180degreesandbringitbacktoapproximatelythesame
speedusedintheprimarydirection.Youdon’tneedtoholdexactlythe
samespeedfromtheprimaryrun,butthecloser,thebetter.Maintaina
consistentspeedanddirection.
Tap“Reverse”andwaitfortheapptocountdownwhiletheaverage
speedsarecalculated.Thesecondrunintheoppositedirectionallows
theapptocalculatethespeedofthecurrentinthewaterandremoveit
fromthecalibration.
Oncecomplete,theappwilldisplaythecalculatedpercentage
adjustment.Tap“Apply”tosavethevalue.
Thespeedcorrectionvaluehasnowbeencalculatedandsavedto
memoryintheDST810.Itwillbeappliedtoallspeedvaluessenttothe
networkandtransmittedwirelesslytotheapp.Alldevicesconnectedto
theNMEA2000networkwilldisplaytheadjustedvalue.
ThevaluecanbemanuallyadjustedbytappingthevalueontheSpeed
Calibrationscreen.

DISTANCEMETHOD
ThedistancemethodofspeedcalibrationwillnotmakeuseofGPS.
Instead,you’lltravelaknowndistanceatarelativelyconstantspeed.The
appwillcalculatetheaveragespeedtraveledusingthetimerequiredto
covertheknowndistance.Itwillalsocalculatetheaverageindicated
speedfromthepaddlewheelandcomparethetwo.
Note:Calibrationusingaknowndistancerequiresbothanaccurate
measurementbetweentworeferencepointsandanaccuratetimeto
travelbetweenthem.Theshorterthedistancebetweenpoints,themore
potentialthereisforerrorinthemeasurement.Aminimumdistanceof
onestatutemileisrecommendedforadistance‐basedspeedcalibration.
Selectthe“Distance”button.
Entertheknowndistancebetweentwopointsintheunitsindicated.
Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant
thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach
boat.


14


Whenyoupassthestartpoint,tap“Start.”Theappwillbegincountingin
seconds.
Whenyoupasstheendpoint,tap“Stop.”Thenumberofrunswill
increasebyoneandthecalculatedspeedswillbeshown.
Thenumberofrunsalreadycompletedwillbeshownas“Completed
Runs.”“TotalTime”isacountofthetotalnumberofsecondsforallruns.
“RunSpeed”showstheaveragerecordedpaddlewheelspeedonthelast
run,while“Speed”showstheoverallaverage.“RunCorrection”isthe
correctionfactorcalculatedonthepreviousrun,and“Correction”isthe
overallaveragecorrectionfactorcalculated.
Followthesameprocessforadditionalruns.Ifyouwouldliketothrowa
runout,tap“DiscardRun”oncecompleteandtryagain.
Note:Ifyou’reperformingthecalibrationinalocationwhereasignificant
currentmaybepresent,makesuretoperformanevennumberofruns
withhalfinonedirectionandhalfreturningintheoppositedirection,as
closeto180degreesaspossible.Thiswillensurethecalculatedaverage
accuratelyaccountsforthecurrent.
Oncecomplete,tap“Apply”tosavethevalue.
Thespeedcorrectionvaluehasnowbeencalculatedandsavedto

HEEL‐CORRECTEDSPEEDCALIBRATION
Note:MakesuretheattitudePGNisenabledontheNMEA2000page.
Onceenabled,makesurethesensorhasbeencalibratedwiththeboat
stationary.RefertotheOffsetsPagesectionformoreinformationabout
calibrationoftheattitudesensor.Heel‐correctedSpeedCalibrationand
theAdvancedCalibrationTablecannotbeusedwithoutattitudeenabled.
Changesinheelangleoftheboatwhileunderwaycanaffectthespeed
calculatedbythepaddlewheel.TheDST810canstorecalibrationsatup
totwodifferentanglesoneachsideinadditiontothestandard
calibration.Inordertoapplyaspeedcalibrationatmorethanoneangle,
theadvancedtablemustbeused.
Astheheelangleoftheboatchanges,thesensorwillshiftfromone
curvetothenext,interpolatingbetweenthem.
Forexample,ifa15%compensationisappliedat10degreesofheeland
a5%compensationisappliedat0degrees,thesensorwillapplya10%
compensationat5degreesofheel.
Heel‐correctedSpeedCalibrationsareappliedusingasimilarprocessas
theStandardCalibration.However,thenatureoftheprocessprevents
makingrunsinoppositedirections.Forthisreason,it’simportantto
performthecalibrationinslackwater.
BeginthecalibrationbyselectingthewizardiconontheHeel‐corrected
SpeedCalibrationwindow.LiketheStandardCalibration,theHeel‐
correctedSpeedCalibrationcanbeperformedusingtwomethods.
 SOG:SpeedthroughwateriscalculatedusingaGPSreference
speedoverground.
 Distance:Speedthroughwateriscalculatedusingtraveltime
overaknowndistancesuchasameasuredmile.

SOGMETHOD
TheSOGmethodallowstheAirmarCASTapptocalculateyouraverage
speedovergroundusingtheinternalGPSinyoursmartdeviceor
manuallyenteranaveragevaluefromanexternalsource.
Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant
thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach
boat.


Choosetheangleatwhichyouwouldliketoperformthecalibration.
Makesureyoucanmaintaintheangleofheelenteredinbothdirections;
thesameangleisusedforbothportandstarboard.Theappwill
automaticallyrecognizeaportorstarboardtack;there’snoneedto
specifytherun,onlytomaintainasclosetotheselectedangleas
possible.
Oncetravelingatarelativelyconstantspeed,direction,andheelangle,
tapthe“Primary”button.Theappwillcountdownasitcalculatesan
averageindicatedspeedfromthepaddlewheelandanaverageGPSSOG.
Theappwillnotpromptforasecondrunasthisisoftennotpossible.It’s
importantthiscalibrationberuninslackwater.
Oncecomplete,theappwilldisplaythecalculatedpercentage
adjustmentforthesidetowhichtheboatwasheeled.Performthesame
processagaintoaddacalibrationfortheoppositeside,andkeepinmind
thetwowillfrequentlybedifferent.Tap“Apply”tosavethevalue.
Thespeedcorrectionvaluehasnowbeencalculatedandsavedto
memoryintheDST810.Itwillbeappliedtoallspeedvaluessenttothe
networkandtransmittedwirelesslytotheapp.Alldevicesconnectedto
theNMEA2000networkwilldisplaytheadjustedvalue.
ThevaluecanbemanuallyadjustedbytappingthevalueontheSpeed
Calibrationscreen.
DISTANCEMETHOD
ThedistancemethodofspeedcalibrationwillnotmakeuseofGPS.
Instead,you’lltravelaknowndistanceatarelativelyconstantspeed.The
appwillcalculatetheaveragespeedtraveledusingthetimetocoverthe
knowndistance.Itwillalsocalculatetheaverageindicatedspeedfrom
thepaddlewheelandcomparethetwo.
Note:Calibrationusingaknowndistancerequiresbothanaccurate
measurementbetweentworeferencepointsandanaccuratetimeto
travelbetweenthem.Theshorterthedistancebetweenpoints,themore
potentialthereisforerrorinthemeasurement.Aminimumdistanceof
onestatutemileisrecommendedforadistance‐basedspeedcalibration.
Selectthe“Distance”button.
Entertheangleatwhichyouwouldliketocalibrateandtheknown
distancebetweentwopointsintheunitsindicated.


Bringtheboatuptocalibrationspeedandtheselectedheelangle.Thisis
thespeedwhereyouwantthegreatestaccuracyinyourspeedreading
andwillbedifferentforeachboat.
Whenyoupassthestartpoint,tap“Start.”Theappwillbegincountingin
seconds.
Thenumberofrunsalreadycompletedwillbeshownas“Completed
Runs.”“TotalTime”isacountofthetotalnumberofsecondsforallruns.
“RunSpeed”showstheaveragerecordedpaddlewheelspeedonthelast
run,while“Speed”showstheoverallaverage.“RunCorrection”isthe
correctionfactorcalculatedonthepreviousrun,and“Correction”isthe
overallaveragecorrectionfactorcalculated.
Followthesameprocessforadditionalruns.Ifyouwouldliketothrowa
runout,tap“DiscardRun”oncecompleteandtryagain.
Note:Ifyou’reperformingthecalibrationinalocationwhereasignificant
currentmaybepresent,makesuretoperformanevennumberofruns
withhalfinonedirectionandhalfreturningintheoppositedirection,as
closeto180degreesaspossible.Thiswillensurethecalculatedaverage
accuratelyaccountsforthecurrent.
Oncecomplete,tap“Apply”tosavethevalue.Theappautomatically
detectsthedirectionofheelandpopulatesthecorrectfield.
Thespeedcorrectionvaluehasnowbeencalculatedandsavedto
memoryintheDST810.Itwillbeappliedtoallspeedvaluessenttothe
networkandtransmittedwirelesslytotheapp.Alldevicesconnectedto

ADVANCEDSPEEDCALIBRATIONTABLE
Note:Theadvancedspeedcalibrationtablewilloverrideanyother
programmedspeedcorrections.Itwillnotbeaddedontopoftheexisting
speedcalibration.Beforeswitchingtotheadvancedcalibrationtable,
makesuretocarefullyquantifytheperformanceofthesensorwithout
anycorrectionsinplace.
TheAdvancedSpeedCalibrationTableallowsfineadjustmentofspeed
correctionovermultiplespeedsandangles.
Uptotwoanglespersidecanbeselected.
Upto10non‐zerospeedscanbeaddedtothetable.
Note:Whenusingtheadvancedcalibrationtable,makesurethehighest
speedinthetableisthefastestspeedthevesselwilltypicallyachieve.If
thespeedexceedsthelargestvalueinthetable,thesensorwillapplya
linearcorrectionofthesameslope.Thiscanloseaccuracyquicklyifthe
lastspeedisverylow.It’simportantthetableincludetheentirerangeof
achievablespeedsregardlessofthenumberofindividualpoints.
Tousetheadvancedspeedcalibrationtable,first
switchspeedcalibrationto“Off.”
Eithermanuallyorusing3
rd
partysoftware,collect
thedifferencebetweenindicatedspeedandactual
speedthroughwaterateachcalibrationpoint.
Thetableisorganizedwithspeedsshownas
columnsandheelanglesshownasrows.Eachcellis
thespeedcorrection(inunitsofspeed,suchas
knots,mph,etc.)appliedtothatspecificheelangle
andspeedcombination.
EnabletheAdvancedSpeedCalibrationTableonthe
SpeedCalibrationTab.Expandthetabletothedesirednumberofrows
andcolumns.Inputthedifferencesmeasuredpreviously.Forexample,if
at0degreesofheeland8knindicatedspeedtheactualspeedthrough
waterwasmeasuredat8.5kn,enter0.5inthatcell.Iftheactualspeed
throughwaterwasmeasuredat7.5kn,enter‐0.5inthatcell.
Makesuretofilloutthetablecompletely.Removeanyunusedrowsand
columnsbyselectingtheheadingandtappingtheX.Theadvancedtable
doesnotadjustthebasicspeedcalibrations;itisastandalonemethodof
speedcalibrationthatoverridestheothers.InaccurateindicatedSTWwill
resultifthetableisnotcompletelyfilledin.



Makesuretosavearecordofthetableasentered.Becausethe
advancedspeedsettingsoverrideallothers,thetablewillbedeletedif
youreturntotheBasicCalibrationsettings.Thetablewillneedtobe
reenteredifyoureturntotheAdvancedCalibrationTable.
Thespeedcalibrationtabswillnotappearwhenthedeviceisin
landscapemode—turnbacktoportraitaspecttodisplaythetabsandexit
theadvancedcalibration.
Note:Makesuretokeeparecordofthedataintheadvancedtable.As
longasthetableisactive,thedataaresavedtomemoryintheDST810.If
theAdvancedSpeedtableisdisabledbyswitchingbacktoBasicorOff,
thedatainthetablewillbepermanentlydeleted.
