Troubleshooting
Browser Cannot Connect to Device:
Check that the host PC's IP address is in the same network segment/domain as the NTP
server.
No Signal Lock Obtained:
1. Check the GPS/GNSS status web page – if satellites are visible with a high SNR (>25),
leave the device for a longer period to obtain a signal lock.
2. Check the GPS status web page – if antenna open or short is displayed, this will indicate
a cable fault.
3. Check antenna position. Check antenna cabling and connectors for visible damage.
Check that any surge suppressor is fitted the correct way around.
Signal Lock Obtained, but NTP Clients Cannot Synchronise:
It can take as long as 30 minutes for NTP to synchronise after a signal lock is obtained.
Wait for 30 minutes and try again.
CAUTION:
Before installing and configuring any T-Series NTP server
appliance, please read the supplied product documentation and
safety instructions carefully. Full product documentation can be
found on the supplied CD.
