Is Leap Year

False

True

False

Specifies if the current year is a leap year.

IP Address 0.0.0.0 to 255.255.255.255 192.168.28.1

Specifies the IP Address of the instrument. This set-
ting cannot be changed directly on the instrument, 
but its value is needed so that the instrument can be 
programmed.

IENA Only System

True

False

False

This setting is used to generate consistent packet 
timestamps. Set to True when the system uses IENA 
timestamps only.

Primary Input

IRIGB

GPS

PTP

IRIGB

Selects which time source PTP, GPS or IRIG-B has 
priority.

Allow Secondary Input

True

False

True

If Primary Input is GPS/IRIG-B then allow IRIG-
B/GPS to act as secondary time source, when pri-
mary is unavailable. 

Settings 

PTP

-

Settings relating to PTP synchronization and time 
conversions.

PTP Protocol

PTPv2 Delay Req

PTPv1

PTPv2 Delay Req

Determines supported IEEE 1588 protocol (PTP) 
where PTPv1 corresponds to IEEE 1588-2004 and 
PTPv2 corresponds to IEEE Std 1588-2008.

PTP Grandmaster

True

False

False

Determines whether the module acts as a PTP 
Grandmaster.

PTP Leap Seconds

0 to 256 

37

Current leap second count. Offset between PTP time 
and UTC time.

Synchronisation Level

500 to 10000 

500

The unit considers itself in sync if the last calculated 
offset from its time master is less than this. Units are 
nanoseconds.
