6.2.1.13.4.2 CONFIG: IP  ANT  PTP
Appendix I. ETHERNET NETWORK CONFIGURATION
All network devices between the Grandmaster and Slave devices must support
PTP for sub-microsecond accuracy.
PTP is a FAST-activated feature that synchronizes computer clocks throughout a computer
network. On LANs, PTP achieves clock accuracy in the sub-microsecond range – much more
accurate than what is attainable by Network Time Protocol (NTP) – and it is also used in network
applications where GPS is either unaffordable or inaccessible. See Appendix I. ETHERNET
NETWORK CONFIGURATION, Sect. I.7.3 Precision Time Protocol (PTP)
PTP Feature = Enabled Transport=Multicast
PTP Grandmaster = LAN
On the top line – Use the ◄ ►arrow keys to select PTP or Transport.
