hopf
Master/Slave-String
The
hopf
Master/Slave-String can be used to synchronize slave systems with the time data
of the master system.
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
•
status information (announcement of DST changeover, announcement of a leap
second and the status of reception of the
hopf
Master/Slave-String source)
3.6.4.5.6.3.1 Specified Settings

•
ETX on the second change; selectable: data string at the
beginning or at the end of the 59. second.
•
local time
