Emitter, receiver or SIM-P module swap: Useful information

Atanytime,onecanreplacetheemitter,thereceiverortheSIM‐Pmodule.Someofthese
replacementsaretransparentintheoperationofthephotocell,somearenot.Theparametersare
storedintheSIM‐Pmodule.Afterapowerup,theparametersarereadfromtheflash
memoryof
theSIM‐Pfornormaloperation.ThereceivercontainsamemorybackupoftheSIM‐P’sparameters.
Theparameterscanberetrievedifnecessary.Theemitterhasnomemorytostoreparameters.In
thefollowingparagraph,eachcomponentisdescribed.

Emitter
Theemittercanbereplacedwithoutanyinfluenceonthephotocelloperation.WhentheSIM‐P
detectsthereceiver,alltheactualparametersneededtooperatecorrectlyaresenttotheemitter.
Assoonastheemitterhasreceivedtheparameters,thephotocellstartstofunction.

Receiver
Anemittercanbereplacedwithoutanyinfluenceonthephotocelloperation.Thereceiverhowever
hasthebackupmemoryoftheSIM‐Pmodule.Whenyoumodifyit,theactualbackupisnolonger
available.IfyoureplacethereceiverandtheSIM‐Pmoduleatthesametime,youcannot
operate
thephotocellasitwasworkingbeforethechange.TrytoavoidreplacingthereceiverandtheSIM
duringthesamepowerdownoperation.ToupdatethebackupmemoryoftheSIM‐Pmodule
insidethenewreceiver,youneedtofollowoneofthesesteps:

Modify oneparameterintheSIM‐Pmodule.Everytimeaparameterischanged,the
completememoryissenttothereceivermemoryforbackuppurposesautomatically.Any
changeofaparametermakesafullupdateinthereceivermemory.
Executethe“saveparameter”commandfromtheSIM‐Pcommandmenu.Thiscommand
willtakethedataintheSIM‐P’sparametermemoryandsenditdirectlytothereceiver’s
memorytoupdatethenewreceiver

SIM‐Pmodule
WhentheSIM‐Pmoduleisreplaced,theparameter’smemoryisgonewiththeoldSIM‐Pmodule. It
meansthatthephotocellwillnotworkasitwasworkingbeforetheSIM‐Pmoduleswap.Youcan,
however,retrievealloftheoldparametersfromthereceiverbydoingthe
following:
Executethe“retrieve”commandfromthenewSIM‐Pmodule.Thiscommandmustbeexecuted
beforeanyparametersarechanged.Ifaparameterischangedfirst,youwillloseallthebackup
parametersavailableinthereceiverhead.
