communicationmodule.Thetimeofthechangeisdeterminedsuchthatthe
meterʹsdataintegrityismaintained.Atthescheduledtime,thecommunication
moduleexecutesthestandardproceduretochangedate/timeonthemeter.
Power Outage/Restoration
Whenanoutageoccurs,themeterusesanearlypowerfailuresignaltoalertthe
communicationmoduletodisconnectfromthemeterʹspowerimmediately.The
communicationmodulesavescriticalmoduledatatonon‐volatilememoryand
createsandsendsapoweroutagemessage.Thismessageincludesthefollowing
information:
•LAN
ID
• Outagetime
• Rebootcount.
Themodulesendsthemessage,thenassistswithroutingotherpacketsuntilthe
back‐upenergysourcecannolongerkeeptheradioalive.Thetimethatthis
energysourceisavailablevarieswithseveralfactors,includingamountofdata
packetsbeingrouted,environmentalconditionsandage
ofendpoint.Generally,a
hold‐uptimeof~45secondsistypical.
Atrestoration,thecommunicationmodulefirstacquiresnetworkconnectivity.
Withnetworkcommunicationsrestored,themodulesendsapowerrestoration
messagethatincludesdetailssuchas:
•LANID
• Outagetime
• Restorationtime
• Rebootcount.
Thecommunicationsmodulestoresahistoryofup
tothelastfivepoweroutage
andrestorationeventpairs.TheUSCHostcanrequestthisdata.
Supporting Passwords
Themeter/modulesupportspasswordsprovidedbytheutility.
Downloading Firmware
EnablemeterfirmwareremotelyviahostorRadioShop.Themodulecanremotely
initiateaself‐restartwithcommunicationsenabled,ifthedownloadedfirmware
causesacatastrophicfunctionalfailure.Oncethemodulecompletelyreceivesthe
newcode,itoperateswiththenewcode.
Encrypting Data
TheUtiliNetNetworkcurrentlysupportsuseofoneencryptionkeypernetwork.
IfyouenabletheS4ewithencryption,thehostmusthaveamatchingencryption
key.Formoreinformationaboutencryptioninthe UtiliNetSolutionCenterhost,

CONFIGURATION TABLES
TheUtiliNetModuleConfigurationstructurepassesthedatatoconfigurethe
module.ItisusedforbothC&IandResidentialapplications.Detailed
