4 Connect the Port A connector of the FlexCable to Port A on the second card. Push down gently but firmly
until the cable is fully connected to the card. Attach the other end of the FlexCable (labeled Port B) to Port B
on the first card.
5 Verify the connection. Make sure the FlexCable ports seat flat against the sockets on the Pro Tools|HD cards,
and are firmly attached.
6 For systems with more than two cards, connect each additional card to its preceding card. Use FlexCables
to connect card pairs together, as described above, until all cards are connected. (Each expansion card is pack-
aged with a FlexCable.)
7 Close the computer case.
Connecting
Audio Interfaces
All Pro Tools|HD audio interfaces require DigiLink connections. When using multiple interfaces, you must
also connect Loop Sync between all Pro Tools|HD audio interfaces. When using multiple Legacy I/Os
(Pro Tools 24|MIX™-series interfaces such as the 888|24 I/O™ and 882|20 I/O™) you must connect Slave
Clock to all Pro Tools|24|MIX-series audio interfaces.
Recommended Ordering of Interfaces
If your setup includes different types of audio interfaces, install them in the following order:
192 I/O or 192 Digital I/O Use as the primary audio interface. These interfaces provide the highest fidelity clock
source for your system.
96 I/O Use as the primary interface (if a 192 I/O or 192 Digital I/O is not installed), or as an expansion inter-
face connected to the Expansion port of the primary interface.
96i I/O Use as the primary interface if no other Pro Tools|HD interfaces are installed, or as an expansion inter-
face connected to the Expansion port of another Pro Tools|HD interface.
Legacy I/Os See “Connecting Legacy Audio Interfaces” on page 8.

If you have at least one 192 I/O™ or 192 Digital I/O™ in your Pro Tools system, it should be the primary
audio interface and Loop Sync master.
