TIMESYNC_ N _MODE= Valid values are:
• Free running : Module is using its own clock with no
reference to any other source.
• PTP Multicast : Card is synchronizing to a PTP
grandmaster clock using multicast network messages.
• PTP Unicast : As PTP Multicast but using the delay
request. Reply messages are unicast to minimize network
traffic.
• NTP : Module clock is synchronized to an NTP clock.
Generally less precise than PTP.
TIMESYNC_ N _NETWORK= Network port currently being used for synchronization for
Kudos Pro IP modules, dependent on the choice of interfaces
made on the
Time Sync Configuration page. If PTP and
multiple interfaces are enabled, the PTP synchronization will
switch ports if it doesn't see regular sync messages on the
port.
TIMESYNC_ N _CLOCK_ID= Identification number of PTP clock being used for
synchronization. This is not necessarily the grandmaster clock
identity, as there can be intermediate clocks between the
grandmaster and the card, depending on network
configuration.
TIMESYNC_ N _CLOCK_

STATE=
Valid values are:
• Free running : Card is not being synchronized.
• No Lock : PTP being used but clocks haven't synchronized
/- 1mS.
• Locked : PTP being used and clocks are within the
accepted range.
• NTP : Module using NTP to synchronize.
TIMESYNC_ N _AVG_

DELAY=
The current network delay time between the card and the
clock sending the synchronization messages. This should be
relatively constant and is dependent on network
configuration.
TIMESYNC_ N _STDV_

DELAY=
The current standard deviation in the network delay time
between the card and the clock sending the synchronization
messages. Should be a low number as the network delay is
expected to be constant.
TIMESYNC_ N _AVG_

ERROR=
The current difference between the cards time and the
grandmaster time. Should be close to zero once card has
synchronized.
TIMESYNC_ N _STDV_

ERROR=
The standard deviation in the average error.
TIMESYNC_ N _

GRANDMASTER=
Identity of network clock acting as PTP grandmaster. This is
the source of the PTP synchronization messages used by all
PTP slave clocks on the network. If there are multiple
grandmasters, they should negotiate between themselves to
identify the most accurate and then silence the others.
