About i.LINK
This section explains the general specifications and major
features of i.LINK. Read this section before doing any
i.LINK-related operation.
Note that i.LINK connections and operations may vary,
depending on the component. For details regarding the
connection of i.LINK components to this unit, see “Audio
Component Hookups” on page 6.
i.LINK functions
i.LINK is a serial digital interface that supports the
bidirectional transmission of audio and video signals,
commands, and even component status information. All
that is needed to hook up i.LINK components with i.LINK
connecting cables. Audio and video components
connected within an i.LINK configuration can be used to
perform a wide range of operations and data exchanges
that is sure to expand as the number and variety of i.LINK
components grows.
Since i.LINK allows data to be transmitted from one
component to other components to which it is not directly
connected, there is no need to pay attention to connection
order. However, due to differences in characteristics or
specifications, operation of or data exchange with certain
i.LINK components may not be possible, even when they
are connected.
z What is i.LINK?
i.LINK is a trademark proposed by Sony Corporation and
accepted by companies throughout the world as an easy-to-
remember name for the IEEE 1394 world standard of the Institute
of Electrical and Electronics Engineers.
i.LINK connections
The use of i.LINK connecting cables to connect i.LINK
components as shown below is called a “daisy chain”
configuration.
i.LINK connecting cable
Data can be transmitted between any two
components even if they are indirectly connected.
Branch connections
• Any i.LINK component with three or more i.LINK
connectors can serve as a branch point.
• Up to 63 i.LINK components can be connected in a
single configuration. However, the maximum number
of components that can be daisy-chained in a single
route is 17 (i.e., a maximum of 16 i.LINK connecting
cables in a row). Each i.LINK cable used in a single
route is called a “hop.” For example, there are six hops
in the route between A and C in the illustration below,
and three hops in the route between A and D.
B A
D C
Each route between A and B; A and C; A and D; B and C; B
and D; and C and D in the illustration above can have 16
hops (i.e., 17 components).
Loop-connection
A signal output from one component is transmitted to all
other components. A loop connection should thus be
avoided to prevent the return of a signal to its source.
