Is Sony's i.Link port exactly the same as a standard IEEE 1394?
Can a standard FW cable be used to download movie files from a
Sony handycam via the i.Link port to a computer FW input?

The physical layer protocol should be exactly the same. The only
issue to work, is connectors or adapter cables.

The physical protocol is point to point, with the ability to build
networks of devices. Each connector is isolated from the other, by
the interface chips. The wiring is differential, with two wires
per dotted line in the diagram, or four wires total for the data
portion. The six wire connector has two additional wires which carry
bus power. When a six pin to four pin cable is used, the two power
pins in the six pin end, are not connected electrically.

Host TX ---------------- RX Some TX ------------- RX Next
RX ---------------- TX Device RX ------------- TX Device

Thanks. So Sony has not built in any proprietary standard into
their i.Link port?

In this cable advertisement at Dell, for a 6 pin to 4 pin cable, it says

http://accessories.us.dell.com/sna/productdetail.aspx?sku=A1612552

Conforms to i.LINK (IEEE1394 Standard) and provides high speed
data transfer (400Mbps)

So it is just IEEE1394 or Firewire.

The fact there are different names, has to do with the development
history and royalties. I would expect most PC applications now,
to refer to the IEEE standard 1394, to avoid any trademarks
that cost money.

http://en.wikipedia.org/wiki/Firewire

"Sony's implementation of the system, known as "i.LINK" used a smaller
connector with only the four signal circuits, omitting the two circuits
which provide power to the device in favor of a separate power connector.
This style was later added into the 1394a amendment.[3] This port is
sometimes labeled "S100" or "S400" to indicate speed in Mbit/s."

So as long as you have an adapter cable, to connect to the plug on
the computer, you're fine.

Firewire has a protocol stack, and various stacks for different devices.
SBP2 (SCSI Bus Protocol 2) is for Firewire storage. IEC61883 standard is
used for DV transfer (or something like that). There is also an option
for IP networking over Firewire, which is no longer supported in Vista,
but is supported out-of-the-box in WinXP.

Got it. Thanks again.
