Parameter Description Value
Parameter Description Value
IRIGYear When the module has an IRIG-B time source, the year is not passed
over IRIG-B. Enter the current year here in the output image.
Example:
30 April 2014
IRIGYear = 2014
UTC_Offset The UTC_Offset is used only when the time source is IRIG-B, and PTP
output is enabled.
IRIG-B provides the UTC time, while PTP requires International
Atomic Time (TAI). The difference between the two is the UTC offset.
Example:
30 April 2014
UTC_Offset = 35
Be sure to verify the current UTC offset. The UTC offset changes
ap
proximately every 18 months.
