The web interface

Connect to the web interface by entering the following address into the address field of
your web browser: http://198.168.10.10

(You need to replace 198.168.10.10 with the IP address of your LANTIME). If you

want to use an encrypted connection, replace the

http://

with

https://

in the above

address. You may be prompted to accept the SSL certificate of your LANTIME the first
time you are connecting to the system via HTTPS.

In both HTTP and HTTPS mode, you will see the following login screen:

On this start page you see a short status display, which corresponds with the LC display
on the front panel of the LANTIME unit. The upper line shows the operation mode of
the GPS receiver. Beside “GPS: NORMAL OPERATION” you may read “GPS: COLD
BOOT”, “GPS: WARM BOOT” or “GPS: UPDATE ALMANACH”. If the connection
to the antenna is broken, a “GPS: ANTENNA FAULTY” may appear.

In the upper right corner of the LC display the time and time zone can be found, below
that you will find the date and weekday.

On the second line the systems reports the NTP status, during the initial

synchronisation process a “NTP: not sync” indicates that the NTP system is not
synchronised, this can also appear if the GPS looses synchronisation and the NTP
switches back to its “LOCAL CLOCK” time source .

The GPS clock is connected to the LANTIME system internally by using a serial
connection and additionally by using the second pulse. So, there are 2 reference clocks
used by NTPD, the GPS and PPS time source. You will find the two time sources in the
status information of the NTPD. After the NTP is synchronised, the Display shows
“NTP: Offset GPS: x” or “NTP: Offset PPS: x” where “x” is the actual offset to the
GPS or PPS time source.

This page will be reloaded every 30 seconds in order to reflect the current status of

the unit. Please keep this in mind when you try to login and enter your password. If you
do not press ENTER or the Login button within 30 seconds, the password field is
cleared and you have to start over again.
