4. Clock Source and PTP Parameters
Clock Source
GPS / PTP
In the PTP mode, LiDARs do not output
GPS Data Packets, as detailed in Appendix
I PTP Protocol.
NOTE 4-pin connectors only support PTP
as the clock source.
When PTP is selected as the clock source:
Profile
1588v2 (default) or 802.1AS
IEEE timing and synchronization standard
used
PTP Domain
Number
Integer from 0 to 127
Domain attribute of the local clock
PTP Network
Transport
UDP/IP (default) or L2
UDP/IP follows the PTPv2 standard
defined in IEEE 1588-2008
L2 follows the gPTP standard defined in
IEEE 802.1 AS
PTP
logAnnounceInter-
val
-2 to 3 log seconds
Time interval between Announce
messages (default: 1)
PTP logSyncInterval
-7 to 3 log seconds
Time interval between Sync messages
(default: 1)
PTP
logMinDelayReqIn-
terval
-7 to 3 log seconds
Minimum permitted mean time between
Delay_Req messages (default: 0)
