Click the I/O tab in the GE Config window.
2.
In the Sync area, click the radio buttons to choose between Outputs report the sync
state and Outputs always report 'in sync'.
The selected sync reports apply to output from both ports.
2.1.
If Outputs report the sync state is selected, you can check the box to suppress
sync reporting when out of sync.
2.2.
If Outputs always report 'in sync' is selected, you can check the box to always
report that the sync relay is on, suppressing the sync relay alarm.
3.
Set the Holdover time in minutes.
The Holdover time sets the period of time that elapses after loss of sync (from GPS/
PTP/NTP) before the MultiSync 100 reports a loss of sync. The holdover feature masks
the effect of a momentary loss of sync due to poor satellite coverage, network
interruption, etc. The default setting of 1 minute ensures output remains within 10
microsecond precision. Increasing the Holder time decreases output precision.
