Parameter Setting Description
PTP device type
End to End
transparent clock
A transparent clock that supports the use of the end-to-
end delay measurement mechanism between slave
clocks and the leader clock.
Peer delay
mechanism
2 step
A clock that provides time information using the
combination of an event message and a subsequent
general message.
Clock domain 0–3
A logical grouping of clocks that synchronize to each
other using the protocol, but that are not necessarily
synchronized to clocks in another domain
Ethernet
switches
PTP V2
compatible
All switches and other devices in the network must
support IEEE 1588 PTP V2 to achieve the stated time
precision and accuracy
Star network topology
In addition to PTP system related settings, the accuracy of your meter clock also depends on your
physical network configuration. A star network topology is required to achieve the level of clock
precision specified.
A Ethernet switch or hub
B Ethernet connected meters
C PTP leader clock
9810 series - User manual Time and timekeeping
