4.6. Asynchronous Broadcasting
Asynchronous broadcasting is supported where using node 63 of the FireWire bus is used as a target node for
asynchronous write request. This enables all the cameras to be triggered by software simultaneously. By utilizing
Asynchronous Broadcasting user can execute and control all the cameras on the same FireWire bus at the same time
with a single command.
