5.6 .edge - Synchronization
Each processing blade can sync to an external reference signal, PTP arriving from the media network or its own internal
sync generator.
Usually, PTP (Precision Time Protocol) is the preferred option. If PTP is not available, then you can connect up to two
external reference signals (to the IN connectors on the rear I/O plate) and daisy-chain these to other devices (using the
THRU connectors). If there is no PTP or external reference, then the processing blade can sync to its internal sync
generator. In this mode, all streams are free-running.
In each case, the sync reference must be set manually (as described below).
Configuration via HOME
The sync reference for a processing blade is defined using the Synchronization options ( in HOME's Advanced parameters).
From the main "Devices" list, click on the processing blade label (to open the "Device Details" as described earlier ). Then
select the Advanced tab and Synchronization .
Synchronization (main page)
From the main page, the Mode Select field sets the system reference. The Status Summary shows Locked when a valid
reference is selected.
If Mode Select is set to PTP, then the PTP sub-pages become relevant.
Changing the Sync Reference
Click on the Mode Select field to set the system reference. There are four possible options:
External Ref 1 – connected to REF 1 IN on the rear I/O plate.
External Ref 2 – connected to REF 2 IN on the rear I/O plate.
PTP – from the media network.
Free Run – the internal sync generator.
The PTP , External Sync#1 and External Sync#2 fields show the Locked/Unlocked status of each option.
If the system reference is set to one of the external inputs, then the Ext Reference Format field shows the format of the
incoming signal.
