Connecting Pro Tools|HD
Cards
Digidesign TDM FlexCable
Digidesign TDM FlexCable cables connect one
Pro Tools|HD card to another. You will need an
additional TDM FlexCable for each additional
card.
Each HD card has two ports along the top of the
card, labelled Port A and Port B. The FlexCable
has two connectors, also labeled Port A and Port
B, to ensure proper connection.
When installing multiple HD cards, data com-
munication across HD cards is achieved by us-
ing the TDM FlexCable to connect Port B of the
first card to Port A of the next card.

1
Shape the FlexCable before installing it on
your HD cards by grasping the cable with both
hands and moving the Port B portion of the ca-
ble 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 ca-
ble.
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 down
gently but firmly until the cable is fully con-
nected to the card. Attach the other end of the
FlexCable (labeled Port B) to Port B on the first
card.
4
Verify the connection, as shown below (orien-
tation may be different depending on your type
of CPU or chassis).
Preparing TDM FlexCable for installation
The first FlexCable always go from Port B
on the HD card to Port A on the Accel or
Process card.
