Q:
Into which of the two DigiSerial Ports on my HD Core card do I plug my Sync I/O?
 
A:
SYNC I/O includes a 4 meter (approximately 12 foot) standard Macintosh serial cable. Connect one end of the Host Serial cable to the SYNC I/O Host Serial port. Connect the other end to the DigiSerial port closest to the Digi-Link connector. Do not use any other DigiSerial ports on your HD Core, or any other HD-series card, for SYNC I/O.
