Synchronization – Configuration of the External Time Reference
Depending on the ETC model it is possible to synchronise the master clock from one out of eight
different time sources:
No
Synch.
DCF /
HBG
MSF
Min. Imp.
GPS 4500
IF482
GPS-TSIP
GPS-
NMEA
CAS CAN
ETC 12(R)
1)
ETC 14(R)
1)
ETC 24(R)
1)

Set time manually.
The four time sources IF482, GPS-TSIP, GPS-NMEA, CAS and CAN (RS 232 only) use serial
synchronisation. GPS synchronisation (TSIP and NMEA) is only possible via RS 422 interface
(COM2). For IF482 and CAS synchronisation you are free to choose between the RS 232
(COM1) and the RS 422 (COM2) interface (refer to chapter 10.2).
If a time source is selected which uses serial synchronisation the communication parameters
(Baudrate, Parity, Stop Bit, Data Bit) for the corresponding interface are set automatically. The
settings for COM1 and COM2 interface can be checked in the Serial Communication Menu (refer
to chapter 13).
It is only possible to use one serial interface (COM1 or COM2) as a time source input at the
same time.
10.1 Time
Source
Select the external time source (time reference).
MENU
Synchronisation
Time source:
Select from:
None, DCF, MSF, Minute Impulses, GPS4500, GPS-TSIP, GPS-
NMEA, IF482, CAS
and
CAN.
For definitions of the
NMEA
and
IF482
protocols, see Annexe E.2 and E.3.
For the synchronisation with
minute impulses
, an additional optocoupler interface (art.
no. 118922) is necessary, see also Chapter 8.6.
The time source must be selected prior to setting the associated time zone (Chapter
10.5).
