AcomData mini Pal In-Depth

FireWire 400 Hard Drive

mini Pal's internal hard drive boasts state-of-the-art features, including 7200
RPM rotational speed, up to 8 MB cache, giant magnetoresistive (GMR) tech-
nology, and advanced integrated electronics, for great performance and solid
reliability. The FireWire 1394a interface makes the drive ideal for even the
most demanding applications––including capturing and editing full-motion,
digital video. As a data backup device, the drive offers much higher transfer
speeds than tape or optical media, and you get tons of storage for photos,
music, graphics and your important documents.

FireWire 400 Hub

mini Pal is equipped with three 6-pin FireWire 400 (1394a) ports. One port
is used to connect mini Pal to your computer (it does not matter which port
you use); the remaining two ports can be used for connecting a whole slew of
FireWire peripherals (digital camcorders, optical/hard drives, scanners etc.) on
two daisy-chains (additional FireWire cables sold separately). See "Connecting
FireWire Peripherals" for details.
Hi-Speed USB 2.0 Hub
mini Pal is equipped with one USB 2.0 type B port and four USB 2.0 type A
ports. The single type B port is used to connect mini Pal to your computer.
The type A ports can be used to connect other USB devices (additional USB
cables sold separately). See "Connecting USB Peripherals" for details.

On-Bus Power

Some low-powered USB and FireWire peripherals have the option of being
bus powered. This means they do not need to be plugged into an AC outlet;
they can get the power they need via a USB or FireWire connection.
mini Pal's USB 2.0 hub can supply up to 2.5 Watts of power from each USB
type A port, with a maximum of 5 Watts for all four ports. The combined peak
power of all attached, bus-powered USB devices cannot exceed 5 Watts. For
example, you can connect two 2.5-Watt devices, or four 1-Watt devices...etc.
The FireWire hub can supply up 8 Watts of power, shared among the three
FireWire ports. Since one FireWire port is used to connect mini Pal to your
computer, the 8 Watts is actually only shared by the two remaining FireWire
ports. The combined, peak power usage of all attached, bus-powered
FireWire devices cannot exceed 8 Watts. For example, you can connect one
FireWire device that uses 8 Watts, or two devices that use 4 Watts each... etc.
The USB and FireWire connections will only supply electrical power when
needed. An attached USB or FireWire peripheral that is plugged into an AC
outlet will not draw power from the USB or FireWire connection.
Before attempting to run any device off of bus power, check the device
manufacturer's specifications to make sure that the device can actually be bus
powered.
