14. Positional change from an External PTP Grandmaster
When the DXD is referenced to an external PTP Grandmaster and a disruption or an error causes a positional change in
the PTP Grandmaster, the DXD will respond differently based on how it has been set by the operator.
14.1 JUMP TO RELOCK
When the time difference detected between the external PTP GM and the DXD System Time is
above
the Jump Threshold
value, the DXD will jump to the new time and relock through the normal lock procedure. This will cause disruptions on the
output signals but will be the fastest way to be locked with the external PTP GM.
The Jump Threshold can be adjusted in menu 1.2 from 5 msec to 15 sec or set to ‘Never’ (default value is 5 msec).
