Description
Internet and
is suitable for
systems that
require accuracies
in the order of 1
ms.
IEEE 1588 v2
ü
ü
IEEE 1588
is designed
to provide
networked,
packet-based time
synchronization
between different
networking nodes
(PTP devices).
The RUGGEDCOM
RSG2288 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
RSG2288 supports
ordinary clock,
boundary clock
and transparent
clock modes. An
ordinary clock
can be configured
as either a
Grandmaster Clock
(GM) or a Slave
Clock (SC) within
the master-slave
hierarchy.
Every Ethernet
port on the
RUGGEDCOM
RSG2288 supports
IEEE 1588. For
