i.LINK (IEEE 1394)

The i.LINK format, also known as IEEE 1394, is an international
specification for the transferring of extremely fast data.
This unit is ready for i.LINK (AUDIO).
By connecting an i.LINK (AUDIO)-capable device to the IEEE 1394
(or i.LINK AUDIO) terminal on this unit using an i.LINK cable, you
can transmit Super Audio CD multi-channel signals that could
not be transmitted except in analog format in the past. With
i.LINK AUDIO, Super Audio CD can be transmitted in its original
digital format, in addition to the capability of transmitting 2-ch
linear PCM data and multi-channel compressed audio signals.

If you have multiple i.LINK-capable devices, you can connect
them through other devices to transmit data between them.
With i.LINK, you don’t need to be concerned about the order of
connection and wiring errors and phase issues are virtually
eliminated.

Copyright protection system DTCP

To play back audio sounds recorded on Super Audio CD or DVD
discs using i.LINK, both the player and the D/A converter need to
be ready for the copyright protection system DTCP (Digital
Transmission Content Protection). The D-01 already accepts
DTCP.

Data transfer rate

There are three transfer rates: 100 Mbps (S100), 200 Mbps
(S200), and 400 Mbps (S400). This unit is capable of transferring
data at a maximum 400Mbps.

For connection to an i.LINK-capable device, use a commercially
available S400-compliant 6-pin i.LINK cable.

When connecting multiple i.LINK-capable devices, avoid
connecting a device having slow transfer rate between devices
having high transfer rate since this reduces the transfer rate of
your whole system. Connect devices having high transfer rate
towards the source as far upstream as possible.

NOTES

<

Among the i.LINK formats there are “MPEG-2 TS” for BS
digital source and “DV” for digital video for DVD recorders,
as well as the “i.LINK (AUDIO)” (A&M Protocol). Never
connect devices that are not ready for i.LINK (AUDIO) to this
unit. If you do, this unit and others may get out of order or be
damaged.

<

In the process of data transfer, avoid plugging or unplugging
the i.LINK cables while in use or switch the power on and off.

<

Among the i.LINK-capable devices there are some that, if not
turned on, are not capable of relaying data.

<

There is a possibility some i.LINK-capable devices will not
respond to this unit’s command.

How to connect multiple i.LINK-capable
devices

Daisy chain connection

You can daisy-chain up to 17 devices including this unit.

Connection in tree structure

If you are using a device having three or more i.LINK connectors,
you may want to get the connection branched out. This way of
connection allows you to connect up to 17 devices including this
unit.

Your system does not work if data is fed back to the output
device. Be careful not to create a loop.
