FireWire Questions & Answers
both the computer and consumer electronics industries.
Whether connecting game consoles, personal video
recorders, home stereo equipment, digital TVs, hard
drives, CD/DVD-RW drives, printers, scanners, tape
drives or other digital hardware equipment, FireWire is
well-suited to handle all these various requirements.
With the advent of the new FireWire 800 standard,
the revolution created by the original will only grow.
For those working with digital video, the new standard
will enable new bandwidth-intensive applications, such
as multiple-stream, uncompressed, standard-definition
video.
Will FireWire 400 Devices Run Faster When
Connected To A FireWire 800 Port?
Unfortunately, this is not the case. In order to at-
tain FireWire 800 speeds, both the device and port have
to be FireWire 800 enabled. For instance, an external
hard drive with a FireWire 800 9-pin connection will
only reach FireWire 800 transfer rates when it is con-
nected to a FireWire 800 9-pin host bus adapter card
via a properly certified FireWire 800 9-pin to 9-pin beta
cable.
When a FireWire 400 device is connected to a
FireWire 800 port, the FireWire 400 device will only
operate at the original FireWire 400 speeds.
Will FireWire 800 Devices Work On FireWire
400 Ports And Vice Versa?
e new standard was designed to be backwards
compatible, meaning that FireWire 800 devices will still
operate via the original FireWire 400 port. To connect
a FireWire 800 device to a FireWire 400 port, a specific
adapter cable must be used, though. ere are two types
of FireWire 400 ports: 6-pin and 4-pin. For FireWire
800 devices to work, they must be connected by placing
the 9-pin end of the FireWire cable into the FireWire
800 port of the device, and the opposite 6-pin or 4-pin
end into the FireWire 400 port.
e same holds true for FireWire 400 devices being
connected to a FireWire 800 host port. e 4-pin or 6-
pin end of the FireWire cable must be connected to the
FireWire 400 port of the device, and the 9-pin end must
be connected to the FireWire 800 port.
When FireWire 400 and FireWire 800 devices are
mixed, all transfer rates revert to the original FireWire
400 speed.
What Do I Do If My Computer Does Not Have
A FireWire Port?
Most computers manufactured today incorporate
at least one FireWire port. If your computer does not
have a native port, you can install one by adding a PCI
or PCMCIA host bus adapter card. Please contact your
computer supply specialist for a specific card that will
work with your system.
