Antenna Faulty
/
GNSS reference clock (GPS/GLN/GNS):
The antenna has not been detected.
•
Check the connections between the antenna and
a LANTIME.
•
Check the output voltage at the LANTIME an-
tenna connector.
•
To do this, disconnect the antenna cable from the
LANTIME antenna port. The following voltage
value should
•
be measured between the inner and outer con-
ductor:
–
GPS Receiver
→
15-18 V DC
–
GLN Receiver
→
5V DC
–
GNS Receiver
→
5V DC
•
If the voltage is 0V DC, please contact the Mein-
berg TechSupport:
•
If the measured voltage at the antenna port of
the LANTIME is correct, reconnect the antenna
cable and
•
check the voltage at the other end of the antenna
cable.
•
Contact your Meinberg TechSupport and provide
a LANTIME diagnostic file, if you need further
assistance at solving the problem.
Longwave receiver (DCF77-PZF/WWVB/MSF/JJY):
Either the antenna or any other input signal has not
been detected.
•
Check the connections between the antenna and
a LANTIME.
•
Check the status of the received antenna signal
in the main page of the web interface. The dis-
played field strength value should be > 40. If this
is not the case, please check how the antenna is
positioned.
•
Check the output voltage at the LANTIME an-
tenna connector.
•
To do this, disconnect the antenna cable from
the LANTIME antenna port. The following volt-
age value should be measured between the inner
and outer conductor: Long Wave Receiver
→
5
V DC
•
Contact your Meinberg TechSupport and provide
a LANTIME diagnostic file, if you need further
assistance at solving the problem.
