Chapter 2: Installation and Configuration
Hardware Connections
The following are the primary hardware connec-
tions on a SYNC HD:
•AC Power
• Serial to the serial port on the first HDX card,
HD Native PCIe card, or HD Native Thunder-
bolt peripheral
• Clock to Pro Tools audio interfaces
• 9-pin to external machines (requires the
Pro Tools MachineControl Software option)
• Synchronization, including positional and clock
references to and from remote machines
AC Power
The AC connector on SYNC HD accepts a stan-
dard AC power cable. SYNC HD is auto power-se-
lecting (100V to 240V) and will automatically
work with a standard modular cable to connect to
AC power receptacles in any country.
Serial Connections
Serial to Pro Tools Card
Pro Tools systems require a serial connection be-
tween SYNC HD and the serial port on the first
HDX card, HD Native PCIe card, or HD Native
Thunderbolt peripheral.
To connect a SYNC HD to a Pro Tools card:
1 Make sure power is off on all equipment.
2 Connect one end of the included serial cable to
the SYNC HD Host Serial port.
3 Connect the other end to the serial port the first
HDX card, HD Native PCIe card, or HD Native
Thunderbolt peripheral.
Clock for Avid HD Audio
Interfaces and Video
Peripherals
The SYNC HD must be connected to all HD audio
interfaces in the Loop Sync chain.
Connecting Loop Sync for Pro Tools HD
Audio Interfaces
SYNC HD supports Loop Sync, and can serve as
Loop Sync Master. Loop Sync is a dedicated clock
loop for synchronizing multiple Avid HD audio
peripherals (including the SYNC HD).
