tional information is acquired by Pro Tools di-
rectly over the 9-pin cable, not through the
SYNC HD. Refer to the
MachineControl Guide for
complete serial time code information.
Video and Clock Reference
(SD Video Only)
If you have only a single SD (standard defini-
tion) video source, you may want to follow the
wiring tip below to ensure that you have full
functionality in all configurations:
To work with a single SD video source:
1
Connect the SD video signal to Video Ref In.
2
Run a short BNC jumper cable from the Video
Ref Out connector to the Video In connector.
3
Connect the Video Out signal to the video in-
put of your destination VTR or video editing sys-
tem.
The choice of video connector also matters
when choosing a positional reference. For in-
stance, when the SYNC HD is in Generate mode
and Video is the current clock reference, the
time code reference for the generator is always
from the Video Ref In connector. However, if
you select a positional reference other than Gen-
erate, then the signal at the Video In connector
can be used.
Digital Clock
To resolve the SYNC HD to external AES/EBU or
Word Clock:
From Pro Tools:
„
In the SYNC Setup section of the Session
Setup window, select the appropriate digital
clock reference from the Clock Reference pop-
up menu.
From the front panel:
1
Press the Clock Reference switch to select DIG-
ITAL.
2
Press Set, and use the Up or Down switches to
display Digital Reference (dI6 rEF).
3
Press Set again. The LED Time Code Display
displays the current digital reference, which will
be:
• AES/EBU (AES-E8U)
– or –
• Word Clock (I CLOC)
4
Press Up or Down to select the digital clock
you want to use.
5
Press Set.
MachineControl also provides 9-Pin Deck
Emulation mode, but this mode is not sup-
ported through either of the SYNC HD
9-pin ports. See the Digidesign Machine-
Control Guide for more information.
