You need to switch you blank tape deck to regen(erate) (ext)ernal timecode.
Then tell that deck to read the timecode of ur other deck. How u do that at ur end I can't help u with . On my deck rack I have to connect the timecode OUT of the deck im copying from to the timecode IN of the deck im copying to.
You can do all (video, audio, TC) from one machine to the other over HD-SDI. Patch an HD-SDI cable from the source deck to the record deck. On the Record deck, set audio to all SDI input, and in TC menu set it to regen, SDI-L. Play source, record on destination, and clone will be achieved.
