2.4.1 DIPswitchdenitionanddescription
Whenthebatteriesareconnectedinparallel,themastercommunicateswiththe
slavesthroughtheCANinterface.Themastersummarizestheinformationofthe
entirebatterysystemandcommunicateswiththeinverterthroughCANor485..
Nota: DIPswitchfrom(1)to(3)denedifferentprotocolsanddistinguishbetween
masterandslave.DIPswitch(4)forBaudrateselection.
•
DIPswitch(4)OFF:settheRS485baudrateto9600andtheCANto500k
•
DIPswitch(4)ON:settheRS485baudrateto115200andtheCANto250k
ThecommunicationcablefromthemasterCANINtotheinvertercommportshould
bethecorrectone.
IfthemasteristhelatestB4850batterywithDIPswitch.

alltheslaveskeeptheDIP0000,noneedchange.
Master Set5.IfthebatterymoduleisincommunicationwiththeICCby485
communication,turnthemasterDIPswitch“#1”and“#4”to“ON”.Thisisonlyfor
ICC(aspecialcommunicationdeviceofsomeno-communicationinverter),it’sa

timewhilethemasterissetting5.
IftheenergystoragesystemhasonlyoneB4850,itisthemasteritself,andstillfollowthe
abovesteps.
