Features
The AJ-YAD955G is a digital video interface board which is designed to be used
exclusively with the AJ-SD930 and AJ-SD955 series of digital VTRs.
When it is installed in the AJ-SD930 or AJ-SD955 series, video and audio signals as well
as time code signals can be transferred digitally to a PC (*) or digital VTR in compliance
with the IEEE 1394 standard.
* Depending on the application (editing) software and hardware (IEEE1394 interface) being
used, transmission of video signals and audio signals for all channels may not be possible.

AUDIO unless SDTI/1394 has been
selected for VIDEO.
•The recording formats for the input data
are determined as shown in the table
below.
AJ-SD930 and AJ-SD955 series settings
1Check that “ON” has been selected
as the setting for setup menu item
No.220 “AV/C CMD SEL.”
3When inputting signals from the
digital video interface, press the
INPUT SELECT button on the front
panel, and set the front display tube
VIDEO input selection to the
“SDTI/1394” position.  Similarly, set
the AUDIO input selection to the
“SDTI/1394” position.
2Check that “AUTO” has been
selected as the setting for both setup
menu items No.882 “DIF IN CH” and
No.883 “DIF OUT CH.”
*2  No recording is possible when “625”
has been selected as the setting for
setup menu item No.070 “TV SYSTEM”
of the AJ-SD955 or when the AJ-SD930
designed for the 625/50 system is used.
•The formats for the output data are
determined by the setting selected for
setup menu item No.881 “DIF TYPE”
and the playback tape (mode).

Precautions for use
•Ensure that the connections with other devices are made on a 1:1 basis.
•When selecting the digital video interface as the input, “AUTO” must be selected
without fail as the setting for setup menu item No.304 “SERVO REF.”
•When warning E-92 (1394 INITIAL ERROR) appears, disconnect the connecting
cables and re-connect them or turn off the VTRs power and turn it back on.
•The AV signals may be disrupted by turning the power of the connected devices ON
and OFF or by disconnecting and re-connecting the I/F cables.
•It may take several seconds for the system to operate stably when the input signals are
switched or operation is transferred from one mode to another.  Perform recording
operation after the system operation has stabilized.
•The following points should be borne in mind when it comes to recording with the digital
video interface input selected or outputting the signals by the digital video interface.
•The AUDIO LEVEL controls on the front panel will not work.
•The settings in the 800 order of setup menu items relating to the vertical blanking
period will be ignored.
•When playback signals other than regulark1 (normal speed) playback signals have
been input, no guarantees are made for the video and sound recorded or for the video
and sound of the EE system.
•The CUE signal cannot be transferred by the digital video interface.  Neither is it
possible for the audio signals which have been multiplexed on the input data to be
recorded on the CUE track. 
•The following points should be borne in mind when the video input selection has been
set as the digital video interface.
•SDI signals and analog video output signals in the E-E mode will become irregular.
These signals should not be used for recording purposes.  (The teletext signals or
other signals which are multiplexed on the video output signals will also become
irregular.)
•When “SDI” has been set as the audio input selection, the reception of the SDI
embedded audio signals will be adversely affected by noise and other problems (i.e.
the signals will become irregular).
•During SLOW or STILL playback, video and audio signals which have not been
processed as the output signals of the digital video interface will be output.  When
these video and audio signals are monitored on another device, they may be at
variance from the video and audio signals which are played back by this unit.
