External synchronization
SICLOCK TC 400 can be matched to the local official time or GMT via external
synchronization in order to automate or restrict manual actions, such as daylight
saving time switchovers and leap seconds, to a minimum.
External synchronizations can be GPS or DCF77 radio clocks, servers (e.g. time
signal from an NTP server), further SICLOCK TC 400 devices or other signal
sources. They are connected to RADIO CLOCK 1 or RADIO CLOCK 2 or to one
of the four Ethernet ports on the device.
NTP servers are supported as external synchronization on the Ethernet ports.
Possible radio clocks to RADIO CLOCK 1 and RADIO CLOCK 2:
•
SICLOCK GPS1000
•
SICLOCK GPSDEC
•
SICLOCK DCFRS
Third-party products can be connected via TTY (passive). The following protocols
are supported:
•
Demodulated DCF77
•
Serial:
−
Meinberg compatible (including time zones)
−
Meinberg compatible (not including time zones)
−
NMEA (0183/ZDA)
