This cable will work for the Apple Workstation running Final Cut using the Blackmagic PCI capture card connected to our
mediaHUB-HD 422.
Usage
To encode a project, use the "Print to Video" option from the "File" pulldown menu in Final Cut.
•
In the mediaHUB-HD Pro set the following control parameters to start the encode:
•
Control (API Command)
Set to
CONTROLINTERFACE (CIF)

As a check, the VIDEODETECTED (VDE) readback should state "Yes".
Important: this cable will not work for Adtec's mediaHUB-HD Pro when connected to a Tape Deck.
The cable needed for a tape deck connection is a regular RS232 serial cable, connected straight through
with no crossovers in the wiring.
