Installation Overview
Complete instructions for connecting and con-
figuring your Pro Tools|HD system are located 
in the
 Getting Started with HD Guide
. If you are 
connecting the 192 Digital I/O to a new 
Pro Tools|HD system, refer to that guide now.
If you are adding the 192 Digital I/O to an exist-
ing Pro Tools|HD system, you will probably find 
everything you need to get up and running in 
this chapter. Additional information can always 
be found in the
 Getting Started with HD Guide
, 
and the 
Expanded Systems Guide
.
Connecting the 192 Digital I/O 
to an Existing HD System
If you are adding this interface to an existing 
Pro Tools|HD system, follow these guidelines:
DigiLink Cable Connections
The DigiLink cable provided with your 
192 Digital I/O is 18
"
 long. If you need a 12
'
 or 
longer DigiLink cable to connect to the HD Core 
or Process card, you must purchase DigiLink ca-
bles separately.
Guidelines for DigiLink Connections
In order to allow the higher sampling rate inter-
faces to work at their full sampling range, you 
must use a 192 kHz I/O as the Primary I/O sys-
tem includes a 192 Digital I/O or 192  I/O, one of 
these should be the primary audio interface, 
with any additional 192 kHz-supporting periph-
erals connected next, in order to allow the 
higher sampling rate interfaces to work at their 
full sampling rate range. 
If you are also using a 96 I/O peripheral, connect 
it after the last 192 I/O or192 Digital I/O. For 
Legacy peripherals, see “Legacy Port” on page 8.
For additional details on the ordering of audio 
interfaces in an expanded system, see the 
Ex-
panded Systems Guide
.
If the existing system contains a single 96 I/O 
interface:
1 
Disconnect the 96 I/O from the HD Core card.
2 
Connect the DigiLink cable from the DigiLink 
port on the primary HD Core card to the Pri-
mary port on the 192 Digital I/O
Turn off your computer, monitoring system, 
hard drives, and peripherals. Making con-
nections while power is on can damage your 
system.
