Installation and Operation Manual
3.5.3 Reboot System.
Clicking the Reboot button will cause the VZ2 to do a software based reset. This is a full kernel reset of the
unit and takes several seconds to complete.
3.6 NTP/PTP Settings Page.
The setup page can be used to turn and off the two major time server features. The current status of each is
shown in its section.
3.6.1 NTP Server.
The NTP daemon can be started and stopped from this page. By default, NTP support is enabled once 3D lock
is achieved. Click the desired option and then click the Submit button.
3.6.2 NTP Holdover Accuracy.
This slide bar is used to set your required accuracy during holdover when 3D lock is lost. This will range from
1ms @ 80 hrs to 10ms @ 250 hrs. The device will change to Stratum 16 when the set holdover time is expired
and 3D lock is not achieved.
3.6.3 PTP Transmission Method.
The PTP transmission method can be set to either Multi-cast or Unicast. Select the desired mode of operation
and click the Submit button.
3.6.4 Authentication Lease Time.
This slide bar is used to set your desired authentication lease. This can range from 8 hrs to 72 hrs.
3.7 About Page.
The About Page shows contact information and software version of the device.
4. TROUBLESHOOTING
4.1 GPS Lock.
Getting GPS lock on the Time Server is required for it to function. Most GPS lock issues come down to issues
with Antenna location, or cabling. If there are problems getting GPS lock (I.e. the Lock LED doesn't turn on
and the 1 PPS LED doesn't flash each second) trying moving the antenna outside and see if that resolves the
issue. If it does, try a window and see if lock is maintained. If that works, move the antenna back to its
original location and see if lock is lost. This will help determine where lock can be received and where it
cannot. If no lock is achieved outdoors, then something is either wrong with the cabling or the Time Server
itself. Contact CSS for help.
4.2 Resetting to Factory Defaults.
Front Panel Button - Push and hold the front panel button with a small object for 5 seconds. This will cause
the VZ2 to reset to factory default settings.
The front panel button, accessible with a paper clip or other small object, accessible from the front panel of
the VZ2 is used to reset the units software settings to factory original. This is useful when a password is
forgotten or the IP address cannot be determined. To do this, insert a paper clip or ball point pen end through
the hole in the front of the unit until you feel the button depress. Hold this button down for a few seconds
and release the button by extracting the paper clip/pen. It should now have the factory default password and
IP address information.
