Commands relating to the NTP configuration
The purpose of NTP (Network Time Protocol) is to synchronize devices
via a shared network. An external NTP server serves as reference for the
Encoder, which is an NTP client (its internal clock is synchronized with the
NTP server).
Displaying NTP server status and IP address (dntp)
To display the NTP server status and IP address, type
dntp
after the
ViBE prompt:
Figure 2-14. Displaying NTP server status and IP address - dntp command
Editing NTP server status and IP address (sntp)
To edit the NTP server status and IP address, type
sntp
after the
ViBE
prompt:
Figure 2-15. Editing NTP server status and IP address - sntp command
„ To enable/disable time synchronization, type
1
(Enable) or
0
(Disable).
„ To edit the preferred IP address, type the new address on the second
line.
You are advised to manually set the ViBE EM4000 system clock as
close as possible to the NTP server clock. Several minutes are
required to achieve perfect synchronization between the two
platforms.
„
The changes will be acknowledged after the Encoder has been
rebooted.
„
The first synchronization operation may take up to 20 minutes.
