NEBULA OPERATION3

NEBULAOVERVIEW

Thefollowing description providesan overviewof thecapabilitiesof theNebula.

LCD DISPLAY

The4line,20 characterperlineBlueLCD display has whiteLEDbacklighting,giving excellentcontrastand readability

underall lighting conditions. Thebrightness of thedisplay goestofull at thefirst keypress, and reducesafter10 minutes

KEYS

TheNebulaisoperatedby asmall keypad of 6keys. Thekeyoperation isdesignedtobesimpleand toallowtheoperator

fastand easy access toall dimmerfunctions.TheMenu keysteps downthrough themenu tree,whiletheBack keysteps

back.Thekeys Up5,Down6,Left3, and Right4areusedfor navigation,and toadjustvalues.Inmostmenus the

function of thekeyisindicatedinthebottomlineof theLCD (“softkey”), making for easy understanding. If avalueischanged

(such as theDMXStartAddress),thenewvaluewill besavedautomaticallytoflash memory afteratimeoutperiod of10

minutes.Alternativelythenewvaluecan besavedimmediatelyby pressing theBack keytoreturn tothetop menu. Thekeys

may also belockedtoprevent unauthorisedoperation.

LEDS

DMX CONTROL

DMX-512 controliscommonlyusedinTheatreand TV for lighting control. OneDMXlineor “Universe”addressesa

maximumof 512 dimmers. Each Nebulamay beset toeitherDMXStart Modeor DMXPatch mode:

DMXStart Mode

InDMXStart mode, theDMXStart Numberfor thepack may besettoany numberbetween1and 4096.Thestartnumber

means theDMXaddress which Dimmer1responds to.DMXaddressesof thefollowing dimmers arethenset automatically:

theaddress ofDimmer2issettotheDMXStartnumberplus 1, and so on. TheDMXaddress numbermay bechosentobe

any numberbetween1and 4096 toeasethetask ofcalculating dimmernumbers inmultipleDMXuniversesystems—the

Nebulaautomaticallysubtractsmultiplesof 512 fromany number513 and up.

DMXPatch Mode

InDMXPatch mode, every dimmerinthepack may besettoitsownDMXaddress.Using thisbuilt inpatch systemallows

greatflexibilityinmatching dimmers toloads—if alargenumberofloads arerequiredtobecontrolledtogether,any numberof

dimmers (including all dimmers inthepack) can becontrolledby asingleDMXchannel. As withDMXStart Modeabove,The

REMOTE CONTROL

Thedimmers of theNebulamay also becontrolledby RS-485 signalwhenfittedwiththeappropriatesoftware.Inthiscase

theRemoteLEDindicatesthat theNebulaisset torespond toremotecontrol fromwall-platesor computer.

DIMMER PARAMETERS

ThedimmerchannelsintheNebulahaveanumberofparameters which may besetindividuallyfor each dimmer.As

incorrectsetting oftheseparameters can preventtheNebulafromworking as expected,caremustbetakenwhensetting them

up.

Test and Set Dimmer levels

Normallyeach dimmerreceivescontrolfromtheDMXlineor RS-485 controlwherefitted.HowevertheTest/Setoptions

alloweach dimmertobeset toalevelwhich overridestheinputfromthesesources.Thisoverridelevelcan besettoany level

betweenOff and Full. An "All"function allowsall Test/Setlevelstobefadedup or downatthesametime.Each dimmercan

also beflashedinstantlytoFull for identification.The"All"function may also beusedwithFlash,allowing all dimmers tobe

flashedtoFull at thesametime.

TheTest functions areof useduring set-up tohelpcheck lamps or wiring problemswithouttheuseofacontrolpanel. The

Set function isalso useful wherelightssuch as orchestra or working lightsmust beleft on permanently.

Minimumand MaximumDimmer levels

Each dimmermay besettoitsownminimumlevel, and itsownmaximumlevel. The"All"function allowsall minimumor all

maximumlevelstobeset at thesametime.

6NEBULA OPERATION

Theminimumsetting can beusedtokeeplampfilamentswarmfor fast responsetime, or for exampletomaintainlighting

at aminimumlevel of illumination, arequirement oftenneededby orchestra lighting and working lights.

Themaximumsetting can beusedfor exampletoprolong lamplife, which isvery sensitivetoover-voltageconditions.For

thisreason, themaximumsetting has higherprioritythan theminimumsetting.

As bothMinimumand Maximumlevelsmay besettoanywherefromOff toFull, careneeds totakeninsetting theselevels.

Dimmer curves

Each dimmerintheNebulamay beset toanumberof dimmercurves. Curvesfittedas standard are:

Incandescent: TheIncandescentdimmercurveissuitablefor mostTheatreand TV applications using incandescentbulbs

whethernormaltungstenor tungstenhalogentype. Thecurveisspeciallytailoredtoprovidelinear apparent light underthese

conditions.

Non-Dim: TheNon-Dim curveselection isfor usewithloads which mustbeswitchedon and off, such as motors, smoke

machines, and othereffects. Each dimmerusing theNon-Dimcurveswitcheson at auserprogrammableNon-Dimlevel(see

below):any controllevelatthislevelor abovewill switch thedimmertoFull instantly. OnceOn, thedimmerwill stay on until

thecontrollevelgoes5% belowtheNon-Dimlevel. An "All"function allowsall Non-Dimswitch levelstobesetatthesame

time.TheNon-Dim facilitymay becombinedwiththeMinimum and Maximum settings toswitch thedimmeroutput between

any twoselectedoutput voltages.

Television: AmodifiedIncandescent dimmercurvesuitablefor adjusting thecolour temperatureof incandescent bulbs in

TV or Filmstudios. Thiscurveisnot intendedtousedas alinear dimming curve.
