DSP Farm Card
The DSP Farm card provides the DSP power for
mixing and plug-in processing to your
Pro Tools|24 system. The DSP Farm card sup-
ports up to 24-bit and up to 48 kHz sessions.
The DSP Farm card includes a port for connect-
ing up to 8 channels of audio input and output
to your Pro Tools system. You can connect a sin-
gle 888|24 I/O or 882|20 I/O directly to the card.
TDM Ribbon Cable
The TDM Ribbon Cable is used to connect mul-
tiple cards in your Pro Tools system so they can
share data along the TDM bus.
A 5-node cable comes with your system. If you
plan to use your system with an expansion chas-
sis, you can order a TDM Ribbon Cable with
more nodes from your Digidesign dealer.
Installing Pro Tools Hardware
To install Pro Tools TDM hardware, you first in-
stall TDM cards, then for systems with more
than one card, connect the cards with a TDM
Ribbon Cable.
Installing Pro Tools PCI Cards
This section shows how to install Pro Tools
cards in a Macintosh computer. To install cards
into an expansion chassis, see the Expanded Sys-
tems Guide.
To install Pro Tools cards:
1 Turn off your computer and any peripherals.
Leave your computer’s power cable plugged in
so the computer is grounded.
2 Disconnect all cables attached to the com-
puter (such as hard drives, displays, USB and
FireWire connections) except for the power ca-
ble.
3 Open the computer case.
4 Remove the metal access port cover behind
the PCI slot you want to use by removing the
screw and sliding the cover out from the access
port.
5 Install the MIX Core or d24 card into the low-
est-numbered PCI slot in the computer as
shown in the following figures.

The 1622 I/O Audio Interface is not sup-
ported by the DSP Farm. It must be con-
nected to a MIX Core, MIX Farm, or d24
card. Only one 1622 I/O can be connected
to any of these cards. The optional 16-
channel peripheral cable adapter is not sup-
ported by the 1622 I/O.
