About Lightpipe-Compatible Devices
Lightpipe is an industry standard, eight-channel 
optical digital audio connection developed by 
Alesis. Lightpipe is found on many devices, in-
cluding ADAT decks, modular digital 
multitracks (MDMs), sound cards, standalone 
A/D or D/A converters, and digital consoles. 
Word Clock 
The Word Clock In and Out ports let you con-
nect BNC cables to synchronize 003 and 003 
Rack to incoming 1x Word clock, and synchro-
nize other devices to Pro Tools-generated Word 
clock. 
MIDI Connectors
The MIDI In and MIDI Out 1 and Out 2 ports are 
standard 5-pin MIDI ports. The MIDI In port 
supports 16 channels of MIDI input. Each MIDI 
Out port supports 16 channels of MIDI output, 
for a system total of 32 channels of MIDI output.
A MIDI driver for these MIDI ports is installed 
when you install Pro Tools LE, and is recognized 
automatically by Audio MIDI Setup (Mac) and 
MIDI Studio Setup (Windows). These connec-
tors accept standard 5-pin MIDI cables.
Kensington Lock Port
Use the Kensington Lock port to secure your in-
terface with a Kensington Lock (not supplied).
For more information, visit the Kensington web-
site (www.kensington.com).
Footswitch Jack
This connector lets you use a footswitch pedal to 
control either playback start/stop or recording 
punch in/out. Both QuickPunch audio 
punch-in and punch-out and MIDI punch-in 
and punch-out recording are supported. The 
footswitch connector is designed specifically for 
instantaneous (momentary) on/off pedals with 
a 1/4-inch TS connector. Continuous on/con-
tinuous off pedals can also be used, but may re-
sult in unexpected behavior.
IEEE-1394 (FireWire) Ports
These ports, marked “1394” in reference to their 
IEEE specification, are commonly known as 
FireWire ports. These provide connections to the 
computer and other FireWire devices. 
FireWire offers a high rate of data transfer and 
reliability that makes it ideal for audio applica-
tions (such as Pro Tools with 003 family de-
vices). FireWire devices can be daisy-chained to-
gether without the need for terminators.
If you are using a Windows laptop that has 
a 4-pin FireWire port (commonly labeled 
“1394”), see “Additional Software on the 
Pro Tools Installer Disc” on page 15 for 
FireWire cable information.
