Troubleshooting Regarding Real
–Time Reference
Basically, there are no faults if the status monitor has no
red
field at its
Time and Date
page.
If the real
–
time of TCC70XS does not match the expected time, try to find the source of the
problem following the steps below:
1.
Check the real
–
time reference, status fields
Time & Date
–
external reference
➢
Fault: the time at
time
has stopped.
If an external real
–
time reference connected to REF/GPI is used:
•
current source
=
external pps + serial
? If not
→
configuration page
Reference
(3G
–
Video module)
→
select “Reference
–
Source =
External PPS + Serial
“.
•
What is indicated at
format
? Does this format match the serial protocol of the real
–
time reference with all its parameters (baud rate, data bits, parity etc.)?
Configuration page
Reference
(3G
–
Video module)
→
choose the proper format at
“Reference
–
Format“.
•
connected before
= “
no
“? If yes
→
TCC70XS never received valid data since power
has turned on, because either the connection is damaged, or the external reference
did not send any data (maybe an antenna is installed incorrect or a receiver is
damaged).
•
connected before
= “
yes
“
and
accepted before
= “
no
“?
If yes
→
it worked before
but now there is a fail. Either the connection or the external reference is damaged.
If the NTP Client function of TCC70XS is used:
•
current source
=
ntp client
? If not
→
configuration page
Reference
(3G
–
Video
module)
→
select “
Reference
–
Source =
NTP Client
“.
•
Verify the set
–
up of the NTP client functionality at the Ethernet module.
➢
Fault: the time at
time
counts upwards but does not correspond to UTC.
Please verify the current time of UTC. Generally, the reference delivers UTC (formerly
called GMT). Configuration page
Time Zone
(3G
–
Video module)
→
all entries at
“
Reference Input
–
Offset“
should be 00.
➢
Fault:
locked
indicates
“
no
“
.
Additionally,
sync after reset
may indicate “
no
“
and the time at
time
may be inaccurate.
Cause: The time of the reference has become inaccurate. Status
last lock at
indicates
the last moment of a “Lock” state
.
If an external real
–
time reference connected to REF/GPI is used: If an antenna is used,
please check the installation of the antenna. Maybe the antenna or the receiver is
damaged.
If the NTP Client function of TCC70XS is used: Verify set
–
up and status of the NTP
client functionality at the Ethernet module.
