CONNECTING THE POWER CORD
If you own a MIDI Express XT, plug the power cord into 
your MOTU MIDI Interface and then plug the other end 
into a grounded power outlet. We recommend that you 
leave the interface switched off while making cable 
connections during installation.
CONNECTING THE COMPUTER
Using the USB cable included with your MOTU MIDI 
interface, put the Type A plug into a Type A USB jack on 
the computer, the USB computer keyboard, a USB hub, or 
any other USB device connected to the computer that has 
an available Type A USB jack. The USB cable allows the 
computer to communicate with all MIDI devices 
connected to your MOTU MIDI interface. If you have 
several MOTU interfaces, see “Connecting multiple USB 
interfaces” on page 14.
Figure 2-1: You can plug the Type A connector directly into the computer itself,
a USB keyboard connected to the computer, or any other USB device already
connected to the computer that has an available Type A USB jack.
