Allow large time differences:ThissettingenablesNTPservertimesetting,even
wherethereisalargedeviationbetweenthecurrentdevicetimeandtheNTPtime.
Thisoptionishelpfulwherethedevicewasnotregisteredonthenetworkfora
periodoftime,andforexamplehasthewrongdate.OverallNTPallowsadeviation
oflessthan1mstobereached.
AsuitableNTPserverislocatedintheNTPsubfolderontheinstallationCD.
NTPsynchronisationrequiresuptofiveminutestoadjusttotheNTP
timeserverafterthedevicehasbeenswitchedon.TheNTP status
willbeinvalidduringthisperiodandwilldisplaythemessage‘Syn-
chronisedtounspecifiedatstratum13’.
Using DataService
YoucanalsoenabledirectsynchronisationwithaconnectedDataServicewithout
usingtheNTPprotocol.Thus,thecurrenttimeofthedevice’sconnectedPCis
usedasareferenceandthedevicebeginstosetitselftothistime.Thisprocess
maytakemorethananhour.IntheServerfield,selecttheDataServicesetting.
OnlyusethissettingwhennoNTPserverisavailableonyournetwork.Thetime
willbeasaccurateasthatofthePCconnectedtothedevice.
Using GPS clock
ToconnectaGPSclock,forexampleHoluxGR-213,intheServerselecttheGPS
clock @ COM3setting.Thecorrespondingchannel(Device→ Interfaces→ COM3
RS-232)mustbeswitchedoff(disableActive),toenablereception.
OncetheGPSreceiverreceivesavalidsatellitesignal,afterashorttimeNTPstatus
willdisplay‘Synchronized to UHF radio at stratum 1’.
