DVE Betacam Protocol Specifics
This section provides set up information for the Decode NAKs (Not Acknowledgement) for DVEs

command was received but not carried out. When you enable the
Decode NAKs option, the Synergy

assign the number of fields for the switcher to wait for a message before re-sending the Play
command.
