Network GenLock mode
In Network GenLock mode, one of the source IP converters is designated as the network sync leader, and all other IP
converters become followers.
The leader IP converter generates a network sync signal internally, and the followers operate in sync with the network sync
signal.
When the video signal transmitted to a destination IP converter is switched, the switching time is shorter because the sync
leader does not change.
On the other hand, the video signal transmission delay time is longer because the input video signal and network sync
signal are not synchronized.

Notes
• In Network GenLock mode, if the IP converter designated as the sync leader is not connected, syncing of the video
signals fails and the system may become unstable. Ensure that the IP converter designated as the sync leader cannot be
turned off during operation. Accordingly, do not use an IP converter mounted on a trolley that is moved between ORs
as the sync leader.
• When sharing trolley devices between ORs, the IP address of the Network GenLock leader and the PTP domain number
of the Network GenLock group must be the same as for the OR.
