1.6.1 Supported Time Synchronization Sources
The following time synchronization sources are supported by the RUGGEDCOM
RS416, with or without the PTP card:
NTP
NTP (Network Time Protocol) is the standard for synchronizing the clocks of
computer systems throughout the Internet and is suitable for systems that require
accuracies in the order of 1 ms.
IRIG-B PWM
IRIG-B time synchronization is an even older, established, inter-device time
synchronization mechanism providing accuracy in sub-milliseconds.
IEEE 1588
IEEE 1588 is designed to provide networked, packet-based time synchronization
between different networking nodes (PTP devices). The RUGGEDCOM RS416
supports PTP v2, which is defined in the IEEE 1588-2008 standard. IEEE 1588
is designed to fill a niche not well served by either of the two older, dominant
protocols, NTP and IRIG-B. IEEE 1588 is also designed for applications that cannot
bear the cost of a GPS receiver at each node or for which GPS signals are inaccessible.
The RUGGEDCOM RS416 only supports ordinary clock mode. An ordinary clock can
be configured as either a Grandmaster Clock (GM) or a Slave Clock (SC) within the
master-slave hierarchy.
