This is separate from the PC port, which I assume is just an input for triggering. So many details to look into with these new flashes before deciding whether to plunge in or wait for 580 adaptors to be available.
Yes, I noticed the port for the SR-N3 cable. I assume it would only send a signal if the radio system were configured to remotely release a shutter or in linked shot mode. Still - worth a try to see if it sends a signal when the flash fires.
