Programming Tips
ThefollowingaresometipstohelpwhenprogrammingtheRealScan74.
•
TurnthehostterminalOffordisconnectallinterfacecablestotheRealScan74
beforeenteringtheprogram.Somehostterminalscancorrupttheprogramifthey
arerunningandareconnectedtotheRealScan74whileenteringtheprogram.
•
ToexitaParameterProgramwithoutenteringalltheparameters,scantheAbort
tag.Onlytheparametersequencewhichwasabortedisnotsaved.Anyprior
sequencethatsuccessfullyendedwiththescannersayingʺProgramModeʺis
saved.Tosavethechangedparameters,scantheSaveandResettag.
•
Toexitprogrammingmodewithoutsavinganyparameterchanges,scanthe
AborttagwhileinProgramMode.TheRealScan74goesthroughinitialstartup
andoperatesusingtheoldprogram.
•
IfunknownhowtheRealScan74isprogrammed,setallparameterstodefault
values,thenenteranyrequiredchanges.DothisbyscanningtheDefaulttagfirst
afterapplyingpowertotheRealScan74.Next,scantheProgramModetagto
entertheProgramModeandentertheprogrammingchanges.
Note:
Someparametersdonothavedefaultvaluesandarenotchangedwhenthe
Defaulttagisscanned.
