Chapter 2: Installation and Configuration 13
To supply AES/EBU clock reference from
SYNC I/O:
■ Connect the SYNC I/O AES/EBU output to the
AES/EBU input on a DAT machine or other dig-
ital device. (AES/EBU clock does not support
176.4 kHz or 192 kHz sample rates.)
Connecting MIDI
The SYNC I/O MTC Out port supplies MIDI time
code, derived from conversion (from LTC, VITC
and Bi-Phase) or MTC generation, to synchro-
nize MTC-compatible consoles, sequencers,
lighting systems, and other devices.
MIDI time code from the MTC Out always
matches the time code address displayed on the
SYNC I/O front panel. If you need to supply
MTC from SYNC I/O to another MTC-compati-
ble device, connect the device as described be-
low.
To connect an MTC-compatible device to receive
MTC from SYNC I/O:
■ Connect the SYNC I/O MTC Out port to the
appropriate MIDI input on the device using a
standard MIDI cable.
Pro Tools and MTC
Pro Tools receives MTC from SYNC I/O through
its connection to the SYNC I/O Host Serial port.
This signal does not include standard MIDI time
code, but is instead a high-quality, proprietary
time code signal designed for Pro Tools. A MIDI
Interface is not required for Pro Tools to receive
MTC.
MTC is output constantly whenever SYNC I/O is
generating time code. This output can be muted
when time code (LTC) is idle. See “MTC Output
and Idle Muting” on page 53 for details.
Software Installation
The following sections provide instructions to
install software required to use SYNC I/O with
Pro Tools|HD or with the stand alone SYNC I/O
Setup software (Windows only).
Pro Tools|HD Systems
To install software to use SYNC I/O with
Pro Tools|HD:
■ Make sure you have already installed
Pro Tools software and the related SYNC I/O op-
tions. Each release of Pro Tools software in-
cludes a SYNC I/O firmware updater and
documentation.
SYNC I/O Setup Software Utility
(Windows Only)
When using SYNC I/O in stand-alone mode, the
SYNC I/O Setup software utility is required to
update firmware and enable remote control of
SYNC I/O. Firmware updates are made available
by Digidesign to add capabilities to your
SYNC I/O. Updates can be downloaded from the
Digidesign Web site (www.digidesign.com).
To install SYNC I/O Setup on Windows:
1 Make sure SYNC I/O is connected to a serial or
COM port on your computer. See “Serial Con-
nections for SYNC I/O Setup Software Utility”
on page 8.
2 Insert the CD-ROM containing the latest
SYNC I/O software, or navigate to its location if
you downloaded an update.
3 Launch the installer and follow the on-screen
instructions.
