Connections
The ability to connect and disconnect FireWire devices while power is ap-
plied (or not) is part of the FireWire specification. Since UAD-2 Satellite is
IEEE 1394 compliant, the device may be "hot plugged" while powered up.
Note:
Although FireWire 400 and FireWire 800 devices can be connected to the

Speeds
same FireWire bus via a hub or daisy-chain, special precautions must be ob-
served to maximize bandwidth in these situations.
Note:
mixing FireWire bus speeds.
FireWire 800 devices on a FireWire 400 bus
FireWire 800 devices are backwards-compatible and can be connected to a
FireWire 400 bus (using a 6-pin to 9-pin FireWire cable or adapter). How-
ever in this scenario
(including UAD-2 Satellite) will operate at a maximum of 400 megabits be-
cause FireWire bandwidth cannot exceed the maximum bus speed of the host
computer.

FireWire 400 devices on a FireWire 800 bus
FireWire 400 devices can be connected to a FireWire 800 bus (using a 6-pin
to 9-pin FireWire cable or adapter). In
operate at a maximum of 400 megabits because the FW800 device is lo-
cated after the FW400 device in the daisy chain (the FW400 device forces
all subsequent devices to run at FW400 speeds).
