Pro Tools|HD Getting Started Guide24
The slot numbering in your computer deter-
mines whether you will be working right-to-left
or left-to-right when connecting cards. Refer to
the instructions below for your model of com-
puter.
To connect Pro Tools|HD cards:
1 Shape the FlexCable before installing it on the
card by holding the cable with its printed side
facing you, and moving the Port B portion of
the cable straight towards you and inwards, as
shown below. Do not bend the cable more than
you need to, as you may damage the traces in
the cable.
2 Slide the FlexCable into the notch of the first
card, so that the Port B connector of the FlexCa-
ble can be aligned with Port B of the first card;
and the Port A connector of the FlexCable can
be aligned with Port A of the second card, as
shown below.
3 Connect the Port A connector of the FlexCa-
ble to Port A on the second card. Push gently but
firmly until the cable is fully connected to the
card. Attach the other end of the FlexCable (la-
beled Port B) to Port B on the first card.
4 Verify the connection. Make sure the FlexCa-
ble ports seat flat against the sockets on the
cards, and are firmly attached.
5 For systems with more than two cards, con-
nect 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 packaged with a FlexCa-
ble.)
6 Close the computer case.
Connecting Audio Interfaces
Each Pro Tools|HD audio interface (except the
96i I/O) supplies up to 16 channels of input and
output to your system. Audio interfaces are con-
nected directly to Pro Tools|HD cards, or
through the Expansion ports on other
Pro Tools|HD interfaces.
Each Pro Tools|HD card supports up to 32 chan-
nels. To get a full 32 channels of I/O from one
card, you can connect, or daisy-chain, a second
16-channel Pro Tools|HD I/O to the first 16-
channel Pro Tools|HD I/O that is connected di-
rectly to the Pro Tools|HD card.
Pro Tools|HD supports up to a maximum of ten
192 I/Os, 192 Digital I/Os, or 96 I/Os. Up to five
96i I/Os can be used simultaneously.
