MachineControl Communication Modes
MachineControl supports two machine com-
munication modes: Serial Deck Control and Re-
mote 9-Pin Deck Emulation mode.
Serial Deck Control Mode
With Serial Deck Control mode, you can use the
Pro Tools Transport window to control a deck.
Transport
The setting of the Transport Master (located in
the Pro Tools Transport window) determines
the type of Serial Deck Control, as follows:
Transport = Pro Tools The Transport window
controls the Pro Tools Timeline. When online,
the deck locates relative to actions taken in the
Pro Tools Timeline.
Transport = Machine The Transport window
controls the machine. When online, the
Pro Tools Timeline chases the machine.
Cueing and Pre-Roll
Pro Tools Preference settings let you optimize
MachineControl operation, including adjust-
able machine pre-roll, selectable edit and mem-
ory location chasing.
Track Arming
When the Transport Master is set to Transport =
Machine, you can arm tracks of external ma-
chines from within Pro Tools for layback and
transfer. Features include individual record en-
ables for up to 48 external tracks, with selectable
record protocol and mode. Machine profiles in-
cluded with the software let you preconfigure
track arming for many machine types.
Serial Time Code (or LTC to SYNC I/O)
When the “Use Serial Time Code for Positional
Reference” option is enabled in the Machine
Control page of the Peripherals window (Setup >
Peripherals > Machine Control tab), Pro Tools
can control an external machine via the Serial
Deck Control cable. This setting also enables
Pro Tools to receive time code using only the Se-
rial Deck Control cable, instead of routing LTC
into the SYNC I/O.
(This mode requires that the 9-pin device be ca-
pable of transmitting serial time code, via its 9-
pin connection. It also requires that the deck be
locked to video reference.)
