Time Setup – Wall – NTP
Select NTP from the Sync mode list to synchronize the wall with external NTP servers via the NTP synchroniza-
tion mechanism. Select in the Modules list all H
YDRA modules that shall synchronize with one or multiple external
NTP servers. Modules not selected in this list will internally synchronize to the externally synchronized modules,
which result in the whole wall is synchronized.
Under NTP server all IP addresses of the external NTP servers must be listed. Click Add to open the Add NTP
server dialog to add another NTP server to the list, enter its IP address in the text box and click OK. To remove
an NTP server from the list, select it with a mouse click and click the Delete button.

Setup time dialog – NTP configuration (detail) and Add NTP server dialog
To check the synchronization, an alarm can be configured to report if the HYDRA module lost its NTP synchroniza-
tion, please refer to section
5.3.4 Setup module (Alarm tab). It is helpful to have such an NTP alarm for each HYDRA
module, if the sync mode is NTP (Only NTP not NTP Date).
To initially start NTP synchronization a defined procedure must be carried out.
Once the H
YDRA modules are synchronized with each other, special actions have to be taken, if an-
other external NTP server should be used or if you used LTC/VITC configuration before.
Please see the list of procedures below:
First time starting NTP synchronization:
• Enter the NTP settings in the Setup time dialog, see above.
• Apply the command Reset Software (Wall), see section
5.2.5 Wall Control.
• If you have configured NTP alarms for each H
YDRA, they will be active.
Wait until all H
YDRA modules that are configured for external synchronization are synchronized. You see this
when the NTP alarms of these modules are no longer active.
• Apply the command Reset software (Wall) again, now all other H
YDRA modules will as well synchronize.
Also their NTP alarms will be deactivated.
