Multicast Mode

The clock is synchronized to UTC (Coordinated Universal Time) from NTP server. The clock receives NTP multicast packets transmitted by NTP server in specified time cycle. This type of synchronization requires no clock’s own IP address and is therefore suitable for easy commissioning of large systems of SLAVE clocks. Further this mode supports monitoring and parameter configuration by means of MOBA-NMS software.

For supervision and configuration with MOBA-NMS, either multicast group address can be used or multicast group address having last octet cleared to zero.
