Figure 4-1: Connecting the 896mk3 to the computer via FireWire.
☛ Make absolute sure to align the notched side
of the FireWire plug properly with the notched side
of the FireWire socket on the 896mk3. If you
attempt to force the plug into the socket the wrong
way, you can damage the 896mk3.
High Speed USB 2.0 versus USB 1.1
There are primarily two types of USB host
controllers widely available on current personal
computers. USB 1.1 controllers support simple
peripherals that don’t require a high speed
connection, such as a computer keyboard, a
mouse, or a printer. USB 2.0 controllers support
high speed devices such as the 896mk3. Since the
896mk3 requires a high speed connection, it must
be connected to a USB 2.0 host controller or hub.
For the most reliable connection, it is
recommended that you connect the 896mk3
directly to one of your computer’s USB 2.0-
compatible ports. However, since USB 2.0 hubs are
compatible with both types of devices, the 896mk3
can be connected to a USB 2.0 hub along with USB
1.1 devices if necessary. The 896mk3 will not
operate properly if it is connected to a USB 1.1 hub.
Follow these instructions to determine whether
your computer supports USB 1.1 or USB 2.0:
1 In the Apple menu, choose About this Mac.
2 Click the More Info button to open System
Profiler.
3 In the Contents pane, select USB.
4 Look at the devices in the USB Device Tree. A
device named USB High-Speed Bus represents a
USB 2.0 root hub. A device named USB Bus
represents a USB 1.1 root hub.
If you are connecting via high-speed USB 2.0
1 Before you begin, make sure your computer and
the 896mk3 are switched off.
2 Plug the flat “type A” plug of the 896mk3 USB
cable (included) into a USB2-equipped socket on
the computer as shown below in Figure 4-2.
3 Plug the squared “type B” plug of the USB cable
into the 896mk3 I/O as shown below in Figure 4-2.
