• NTP Mode
: Used to select one of 3 mode types::
o
Unicast
: In Address IP 1, enter the IP address of the NTP server. In this case, it is the
clock that calls the NTP server.
It is also possible to set up redundancy (if the first server fails to respond, the second
is requested and so on). For this purpose up to 5 server addresses may be entered
(IP address 1/2/3/4/5).
The Periodicity field sets the frequency with which the clock requests the configured NTP
servers.
o
Multicast
: In this case, the NTP server broadcasts the time on the Multicast address
given to it. The Multicast address of the clients (receivers) must be the same as the one
on which the server broadcasts.
By default, Bodet products transmit the time or receive using the Multicast address:
239.192.54.1
The Multicast addresses are included between 224.0.0.0 and 239.255.255.255.
o
By DHCP
: As for Unicast mode, except the NTP server addresses are automatically
retrieved via the DHCP server (option 42 enabled on the DHCP server).
The checkbox "Continue to display" is used to define how the clock should respond if NTP
synchronisation has been lost for 48 hours:
•
If "Continue to display" is OFF, the clock blacks out and the colon is fixed.
• If "Continue to display" is ON, the clock continues to operate using its internal time base
and the colon «:» ceases to flash.
