Meinberg SyncBox PTPv2 - Manual (Page 20)

Please keep in mind that peer-delay measurements are not supported when operating
in Unicast mode.
A domain is a logical grouping of clocks that synchronize to each other using the
protocol, but that are not necessarily synchronized to clocks in another domain. Be
aware to use the same domain as configured on the grandmaster.
The PTP standard includes mappings to User Datagram Protocol (UDP), layer-2
Ethernet and other implementations. The SyncBoxV2 will support Layer 3
(IPv4/UDP) Layer-2 Ethernet (IEEE 802.3).
In the “Unicast Configuration” section the IP address of the PTP grandmaster can
be configured. The UUID of the grandmaster should be left to default which is
“FF:FF:FF:FF:FF:FF:FF:FF” if UDP/IPv4 is selected as network protocol. In case
Layer 2 communication is used, the UUID of the grandmaster port should be entered
here. Please make sure that the “Unicast” profile is selected if unicast negotiation
shall be used.
Additional TSU (PTP time stamp unit) configuration parameters can be set directly
in the text files that can be displayed in the „TSU Configuration files“ section.
User Captures can be used to mark hardware events with high precision
timestamps. SyncBox supports two User Capture inputs with TTL level. Time stamps
will be taken with the rising edge of the input signal. With the Option „show user
captures“ the user capture inputs of the SyncBox will be activated and current
captures will be shown in a scrollbox. These user captures can be shown in a
Telnet/SSH session with the command „show_ucap“ also.
