SYNC I/O Guide 14
Configuring Pro Tools|HD and
SYNC I/O
Pro Tools provides SYNC I/O configuration and
firmware update controls. These establish com-
munication between Pro Tools and SYNC I/O.
This section describes how to configure
Pro Tools for the SYNC I/O, how to check your
configuration and firmware, and how to set ses-
sion settings relevant to the SYNC I/O.
Loop Sync
SYNC I/O supports Digidesign’s Loop Sync fea-
ture for connecting HD interfaces. SYNC I/O
can be configured as the Clock Source (Loop
Master), in order to provide Loop Sync master
clock to the rest of your Pro Tools|HD hardware.
Auto ID of SYNC I/O through Loop Sync
Pro Tools|HD automatically recognizes if a
SYNC I/O is connected to the DigiSerial port
when Pro Tools is launched. When SYNC I/O is
recognized, Pro Tools automatically configures
the Device and Port settings for SYNC I/O in the
Peripherals dialog. Pro Tools 6.4 also checks for
recent firmware, and alerts you if you need to
update the SYNC I/O. Earlier versions of
Pro Tools require that you manually check for
firmware updates. (See “Updating SYNC I/O
Firmware with Pro Tools” on page 19.)
To check SYNC I/O and Pro Tools communication:
1 After installing Pro Tools and connecting the
SYNC I/O as described, launch Pro Tools.
2 Choose Setups > Peripherals, and click the
Synchronization tab. The SYNC I/O should be
shown as the Device, with DigiSerial Port as the
selected port.
If these are not shown, check all your connec-
tions, then try manually selecting SYNC I/O and
DigiSerial Port from the Device and Port selec-
tors. Once SYNC I/O is selected in this way, the
SYNC Setup controls become available in the
lower part of the Peripherals window.
3 Click Enable SYNC Setup. Pro Tools scans the
DigiSerial port and checks SYNC I/O firmware.
See “Updating SYNC I/O Firmware with
Pro Tools” on page 19.
For system requirements and Loop Sync
connection instructions, see Chapter 1, “In-
troduction.”
