Domain: Domain number of the selected PTP node.
Unicast: [0,1] OFF or ON (1)
Last Time: [e.g., "2016-08-12 18:19:15"] The last time a packet was received.
Average Rate: [e.g., "0.0624986091344933"] Indicates how often the selected
message has been detected (in seconds e.g., "1.0" would mean once every second).
2.16.2 Enabling/Disabling PTP
To enable or disable PTP:
1.
Navigate to MANAGEMENT > NETWORK: PTP Setup.
2.
In the PTP panel, slide the toggle switch to ON or OFF for the desired Ethernet port.
3.
Configure your settings using the Edit Settings Panel.
2.16.3 General Configuration Notes
Ensure that the Ethernet port used for PTP is connected to the network. Navigate
to MANAGEMENT > NETWORK: Network Setup, and verify the STATUS in the
Ports panel.
For a Master Clock: Be sure that valid time and 1PPS references are currently
selected: Navigate to MANAGEMENT > OTHER: Reference Priority, and confirm
Reference Priority configuration, and Reference Status. Note that in order to
operate properly as a Master Clock, SecureSync must be synchronized to a non-PTP
reference. The built-in GNSS reference provides all information needed with no
user intervention. Should you, however, be using a different reference, ensure that
it transmits the following information.
The proper TAI or UTC time (including the current year).
The current TAI to UTC offset (required even if the reference’s time is in
TAI).
Pending leap second information at least a day in advance.
2.17 GPSD Setup
GPSD is a free, open-source package used worldwide to manage GNSS systems and
devices. With GPSD support on a SecureSync, users are able to:
connect to the unit over a network via TCP at the specified port using any GPSD-
compatable software
