The DuraTime master clock is the focal point of the system. It comes from the factory with an OCXO Oscillator that is aaccuate to one second in 20 years.  It Includes an NTP connection that allows you to obtain time updates from network time servers if you wish.  An optional wireless GPS receiver is available.  The time is then broadcast to all secondary devices once per second. Multiple master clocks may be deployed for improved reliability.

Included with each RC102 unit is:

  • 1 Primary Master Clock
  • 1 Secondary Master Clock
  • 2.4 GHz transceiver
  • AC/DC Power Adapter
