Standard Zeittelegramm (IF 482) mit lokaler Zeit The IF 482 telegram is a time telegram, which sends the time and date
information as ASCII characters through the serial interface RS 232 or RS 422.
Definition: Zeittelegramm (ASCII), endend auf die im Telegramm bezeichnete Communication parameters:

*) Überwachung: Interface : RS232 or RS422
'A': Korrekter Zeitempfang des Sendegerätes
'M': Sendegerät hat mehr als 12 Stunden kein Zeitsignal empfangen
Zeit wird bei 'A' und 'M' vom Uhrwerk übernommen.
**) Lokale Zeit: Synchronization: Telegram ends at the beginning of the second
'W': Winterzeit specified in the telegram
'S': Sommerzeit
'L': Lokalzeit Cycle: 1 second
Wird überprüft, jedoch nicht vom Uhrwerk ausgewertet.

17 End of telegram CR 0D
*) Monitoring:
With a correctly received time in the sender unit, the ASCII character 'A' is
issued. If 'M' is issued, this indicates that the sender was unable to receive
any time signal for over 12 hours (time is accepted with ‘A’ and ‘M’).
**) Season:
W: Standard time,
S: Season time,
U: UTC time (not supported by all systems),
L: Local Time
