UAD System Manual - 106 - Chapter 11: UAD-2 Satellite
Note: UAD-2 Satellite is a FireWire 800 device. See “Mixing FireWire
Speeds” on page 108 for more information about using FW800 and FW400
devices on the same FireWire bus.
FireWire
Connectors
FireWire 400 and FireWire 800 devices use different connectors (Figure 27
below). The connectors are not interchangeable; this helps to differentiate be-
tween the two device speeds.
FireWire 400 connectors
FireWire 400 devices typically have two types of connector: 4-pin and 6-pin.
The small 4-pin FireWire 400 connector is common on digital camcorders
and Windows notebook computers. The 6-pin connector is more common
with hard drives and audio devices; the two extra pins allow the device to be
bus powered (UAD-2 Satellite cannot be powered by the FireWire bus).
UAD-2 Satellite has one 6-pin FireWire 400 port.
FireWire 800 connector
FireWire 800 devices use a 9-pin connector. 9-pin to 6-pin FireWire adapter
cables are available to connect FireWire 800 devices to a FireWire 400 bus
(with reduced bandwidth). See “Mixing FireWire Speeds” on page 108 for
more information.
UAD-2 Satellite has two FireWire 800 ports to facilitate easy daisy-chaining
with other FireWire devices.
Hubs and Chains FireWire devices can be connected to a central hub, such as a computer with
multiple FireWire ports or a peripheral FireWire hub (Figure 28 on
page 107), connected to each other serially in a “daisy-chain” (Figure 29 on
page 107), or any combination of the two in a “tree-chain” topology
(Figure 30 on page 107). Note the diagrams in these figures are only exam-
ples; devices may be connected in any order (see “Mixing FireWire Speeds”
on page 108 for exceptions).
