What is i.LINK?
i.LINK is a digital serial interface that allows devices
equipped with an i.LINK connector to exchange digital
video signals, digital audio signals, and device control
signals bi-directionally over a single cable.
i.Link refers to the IEEE1394-1995 industry specification and
extensions thereof. The A logo is used for products compliant
with the i.Link standard.
This VCR uses a four-pin i.LINK connector to input and
output MPEG2 video signals, audio signals, and control
signals. The i.LINK connector is also used as an input for
DV compressed signals from the DV output of a digital
video camera.
i.LINK Connection
i.LINK-compatible devices can be connected in daisy
chain fashion using i.LINK cables.
Any two devices in the daisy chain can exchange data bi-
directionally, even if there are other devices connected
between them.
i.LINK also supports a repeater function that passes input
MPEG2 and DV signals through to the next device in the
chain.
i.LINK Branched Connection
If you are connecting a device that is equipped with three
or more i.LINK connectors, you can also branch the
i.LINK connection.
i.LINK Connection Examples
Examples of good i.LINK connections and bad i.LINK
connections are shown below. The digital signals flow to
all connected devices. When connecting i.LINK devices,
make sure that the devices are connected in such a way
that digital signals do not return (loop back) to the device
that output them. Looped connection is not permitted.
NOTES:
• You can connect as many as 63 devices (including this VCR) through an i.LINK connection. If you use a branched i.LINK
connection, however, the maximum path length on a branch is 17 devices.
• In the case of a personal computer and some other devices, data is not passed along by those devices if the device power is off. For
details, refer to the instruction manual for the connected device.
Furthermore, data is not passed along by this VCR when “POWER SAVE” is set to “ON” on this VCR (
A page 67) and the VCR is
turned off.
• The maximum data transfer speed supported by the i.LINK connector on this VCR is 400 Mbps (approximately 400 megabits per
second). The maximum data transfer speed that is actually attained may be slower depending on how this VCR is used or if a device
with a slower transfer speed is connected to this VCR.
• Use the commercially available i.LINK cable (4-pin, S400, below 3 m).
If the cable used is above 3 m, this VCR will not fully maximize its performance.
