To check or reconfigure I/O:
1 Start up your computer (see “Powering Up
Your System” on page 11).
2 Launch Pro Tools and choose Setup > Hard-
ware Setup.
3 Select your 192 Digital I/O in the Peripherals
column, and click on the Identify checkbox.
This will confirm that you have properly in-
stalled the 192 Digital I/O. You can similarly
identify and verify any other connected HD I/O
units by repeating these steps for each I/O pe-
ripheral.
If you encounter any difficulties in confirming or
identifying your 192 Digital I/O:
1 Delete the DigiSetup file (located in System
Folder/Preferences).
2 Power down the computer completely.
3 Turn off all interfaces.
4 Turn the power on again for each interface.
5 Reboot the computer. See “Powering Up Your
System” on page 11 for more information.
Powering Up Your System
In order for Pro Tools to communicate properly
with audio interfaces and other peripherals, it is
important that you start up and shut down your
system in the following order:
Power up your system in this order:
1 Turn on your Pro Tools hard drives.
2 Turn on synchronization or other MIDI pe-
ripherals or interfaces.
3 Turn on your 192 Digital I/O and any other
Pro Tools audio interfaces. On power up, the sta-
tus LEDs will flash. Wait at least fifteen seconds
for the 192 Digital I/O to initialize, and the sta-
tus LEDs to stop blinking and stay lit on any and
all audio interfaces. If properly connected, the
ring around the power switch will be orange
while the computer is powered down.
4 Turn on your computer. When the computer
boots, all power LED rings on HD I/Os should
switch to green. This signifies that the I/Os are
properly connected to HD cards or other HD
I/Os in your system.
Legacy audio interfaces will not be available un-
til they have been made active in the Hardware
Setup dialog. See the
Getting Started with HD
Guide for information.
Power down your system in this order:
1 Quit Pro Tools.
2 Shut down the computer.
3 Power off your audio interfaces.
4 Turn off any synchronization, MIDI, or other
peripherals or interfaces.
5 Turn off your drives.
