TIME SYNCHRONIZATION COMMUNICATION INTERFACE CONNECTION

5.3.2. Option 2
One MNS Digital Gateway in the network is configured as NTP Server (Time Sync mode =
RTC). In this case the date and time for this MNS Digital Gateway must be set through the
web interface. All other MNS Digital Gateway are configured as NTP Client (Time Sync mode =
NTP) and their internal clock is synchronized by the NTP Server MNS Digital Gateway.
In case of a power down the MNS Digital Gateway buffers the system time (RTC) for
about 3 hours. Afterwards its internal clock is reset to 2009-01-01.
This time synchronization method is less accurate than Option 1 due to the fact that
one MNS Digital Gateway internal clock is used as time reference and not a high accu-
rate GPS synchronized Time Server.
