5.3.7
hopf
Master/Slave-String
The
hopf
Master/Slave-String can be used to synchronise slave systems with the time data
of the master system up to an accuracy of ± 0.5msec. It differs from the
hopf
DCF77 slave
string in as much as the difference to the UTC time is included in the transmission.
The
hopf
Master/Slave-String transmits:
•
the full time information (hour, minute, second)
•
the date (day, month, year [2 digits])
•
the difference time local to UTC (hour, minute)
•
the day of the week
•
and status information (announcement of ST/WT change over, announcement of
a leap second and the status of reception of the Master/Slave-String source)
