Using Web Management to Configure SNTP
SimpleNetworkTimeProtocol(SNTP)allowstheRBT‐41 02tosetitsinternalclockbasedon
periodicupdatesfromatimeserver.Maintaininganaccuratetimeontheaccesspointenablesthe
systemlogtorecordmeaningfuldatesandtimesforevententries.
TheRBT‐4102actsasanSNTPclient,
periodicallysendingtimesynchronizationrequeststo
specifictimeservers.YoucanconfigureuptotwotimeserverIPaddresses.Theaccesspointwill
attempttopolleachserverintheconfiguredsequence.
ToconfigureSNTP,selectSystemLogfromthemenu,andscrolldowntoSNTPServer.
