To connect a SYNC HD to HD audio interfaces:
1
Using a BNC cable, connect the Loop Sync Out
of the SYNC HD to the Loop Sync In of your
primary HD audio interface.
2
Using a second BNC cable, connect the
SYNC HD Loop Sync In to the Loop Sync Out
of your HD audio interface.
When using more than one HD audio interface,
make the SYNC HD the first and last unit in the
Loop Sync chain.
MachineControl
On MachineControl-enabled Pro Tools systems,
SYNC HD supports limited Serial Deck Control
only. For full use of MachineControl option fea-
tures, a direct serial connection to the host
Pro Tools computer is required.
Serial Deck Control Mode
(Non-Linear Decks Only)
A limited degree of Serial Deck Control mode is
available through a connection to the 9-pin ports
on the SYNC HD.
To connect an external deck to a SYNC HD:

Connect a standard 9-pin cable from one of the
9-pin Out ports on the SYNC HD to the 9-pin
connector of the external deck.
As many as two decks can be connected to the two
9-pin Out ports on the SYNC HD. You can control
one deck at a time, switching between them from
within Pro Tools. These ports on the SYNC HD
support all MachineControl modes except 9-Pin
Remote (Deck Emulation) mode.
9-Pin Remote Deck Emulation
Mode
9-Pin Remote Deck Emulation mode requires a di-
rect serial connection to the host computer.

Due to performance limitations, this
configuration should be used primarily
with non-linear decks.
