Connecting HD OMNI
Pro Tools|HD Systems
HD OMNI provides up to eight channels of ana-
log and digital I/O with Pro Tools when con-
nected to a Pro Tools|HD card using a DigiLink
Mini to DigiLink cable adapter or when con-
nected to the expansion port of another
Pro Tools|HD audio interface (such as HD I/O).
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 OMNI or us-
ing additional Pro Tools|HD cards. However,
Pro Tools supports only one HD OMNI in a sin-
gle Pro Tools|HD system.
To connect HD OMNI to a Pro Tools|HD system, do
one of the following:
 Connect HD OMNI Primary Port to the Digi-
Link Port on the Pro Tools|HD Accel Core card
with a DigiLink Mini to DigiLink cable (in-
cluded with your Pro Tools|HD system).
– or –
 Connect HD OMNI Primary Port to the Ex-
pansion port on a primary Pro Tools|HD audio
interface with a DigiLink Mini cable (HD I/O)
or DigiLink Mini to DigiLink cable (192 I/O,
192 Digital I/O, or 96 I/O).
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.
If the fan stalls or fails on HD OMNI, the
Monitor LCD displays “FANerr,” and the
Monitor LCD backlighting turns red. If this
happens, try power cycling HD OMNI to re-
start the fan. For more information, see
“Fan Failure Mode” on page 49.
