Checking the System
Before you use Pro Tools, you may want to run
the DigiTest diagnostic application to ensure
that all Pro Tools|HD cards in the system are rec-
ognized, installed in the proper order, and have
valid TDM FlexCable connections.
Running DigiTest
DigiTest is installed with Pro Tools and resides
in the following folder on your hard drive:
Digidesign/Pro Tools/Pro Tools Utilities.
To run DigiTest:
1 Quit Pro Tools if it is running.
2 Lower the volume of all output devices on
your system.
3 Locate and double-click the DigiTest icon on
your hard drive.
DigiTest opens and lists the supported cards it
finds in your system, showing their correspond-
ing slot locations.
If you have a large number of cards or audio in-
terfaces, it may take a while for the DigiTest win-
dow to appear, as DigiTest scans for all cards and
interfaces connected to the system.
4 Select the cards in your system you want to
test by selecting Test in the left hand column for
each card.
5 Click Run.
If cards are not installed in the proper order,
DigiTest will display error codes in the Status
box of each card identified as being misconfig-
ured.
The more cards and audio interfaces in your sys-
tem, the longer the test will take.
Before you run DigiTest, lower the volume
of all output devices. Very loud digital noise
may be emitted during the test.

The order in which cards are listed within
DigiTest may not match the actual slot loca-
tions of cards installed in your computer or
expansion chassis. This is normal, and does
not affect DigiTest operations in any way.
