chapter 3
Connecting HD I/O
You can get a full sixteen channels of analog
and digital I/O with HD I/O connected to a
Pro Tools|HD card using a DigiLink Mini to
DigiLink cable.
You can add additional Pro Tools|HD audio in-
terfaces to your Pro Tools|HD system using the
Expansion port on the back of HD I/O or using
additional Pro Tools|HD cards.
To connect HD I/O to a Pro Tools|HD system:
 Connect HD I/O Primary Port to the DigiLink
Port on the first available Pro Tools|HD card
with a DigiLink Mini to DigiLink cable (in-
cluded with your Pro Tools|HD system).
For more information about installing
Pro Tools|HD cards, see the Pro Tools|HD
User
Guide.
Pro Tools|HD audio interfaces need room at
their sides to maintain proper air flow for
cooling. Do not block the sides of the unit or
disconnect the internal fan. If the units are
rack-mounted in a case, remove the case
lids or doors before operating the system.
Failure to do so can result in the units over-
heating very quickly, which can perma-
nently damage sensitive components.
