Zone Message events and commands allow you to synchronize a state among multiple zones in a single presentation.
Notes:
Synchronization is supported over wireless connection on BOS 8.0.146 and newer (older firmware may send/receive sync messages but may not be synchronized). For more reliable synchronization, use a wired network connection.
If the player has more than one active network connection, make sure the players can only communicate between each other over one of the connections, otherwise duplicate sync messages may be sent/received, causing disruption of sync
You cannot synchronize BrightSign players that belong to different product lines.
When using players with different BOS versions (not recommended), make sure the leader (Screen 1 in a BrightWall) has the same or older BOS version as the follower players.
