The significance of the individual bits is as follows:
B7
3D/Position-fix
0
Position-fix evaluation.
1
3D evaluation.
B6
Synchronisation process
0
Standard synchronisation process.
Special synchronisation process / system time status becomes invalid ("–") when the
1
time difference between the internal clock and the synchronisation source is more than
one second.
B5
Error message / switch box control
0
Common error message output on occurrence of a major or minor alarm event.
1
Output control for switch box (5000 system).
B4
Error message / PPS pulse output
0
PPS pulse on the 9-pole SUB-D connector X1, pin 4.
Common error message (major or minor alarm event) on the 9-pole SUB-D connector X1,
1
pin 4.
Time base in the Master/Slave-String (e.g. when synchronising with sync.
B3
module 8023)
0
The time base in the Master/Slave-String is local time (standard setting).
1
The time base in the Master/Slave-String is UTC.
B2
Evaluation of the Master/Slave-String
0
Standard evaluation with all string information.
1
Special evaluation for application with sync. module 8023.
Bit 1 Bit 0 Setting the signalling bit for Summertime-/ Wintertime switchover
0
0
Signalling bits are only set by the external source.
0
1
Signalling bits are set via the external source depending on the system status of the ex-
ternal source or via the internal switchover times:
1
0
Signalling bits are only set in accordance with the internal switchover times of the 7001
system (e.g. required for synchronisation with sync. module 8023).
1
1
Signalling bits are only set via the internal switchover times of the 7001 system (e.g.
required for synchronisation with sync. module 8023).

•
Signalling bits are set by the external source provided that this delivers valid
time information.
•
Signalling bits are set by the internal switchover times of the 7001 system when
the external source is not available.
