Panasonic AJ-SD255 User Manual

IEEE1394 digital interface

Precautions for use

• Connect the interface with another device on a 1:1 basis.

• If the E-92 warning (1394 INITIAL ERROR) is

displayed, either re-connect the connecting cable or turn
the VTR’s power off and back on.

• The AV signals may be disrupted when the power of the

connected devices is turned on or off and when the
interface cable is connected or disconnected.

• When the input signals are switched or the mode is

transferred, it may take a few seconds for the system to
stabilize. Proceed with the recording operation only after
the system has stabilized.

• The following situation applies when recording is to be

performed by selecting the IEEE1394 digital interface
input, and it applies with the signals which are output by
the IEEE1394 digital interface.

- The audio level control knobs on the front panel do

not work.

- The settings in the 800 series of setup menu items

concerning the vertical blanking period are ignored.

- When playback signals other than regular 1x speed

playback signals have been input, no guarantees are
made for the pictures and sound which will be
recorded or for the EE-type pictures and sound.

• The following situation applies when the video input

selection has been set as the IEEE1394 digital interface.

- The SDI signals, the analog video output signals and

time code output signals become irregular in the E-E
mode. Do not use these signals for recording
purposes. (The teletext signals and other signals
superimposed onto the video output signals also
become irregular.)

• During SLOW/STILL playback, unprocessed video and

audio signals are output as the IEEE1394 digital
interface output. When these video and audio signals
are monitored using another device, they may differ from
the video and audio signals played back by this unit.

The recording format for IEEE1394 digital input data is
determined based on the table below.

For AJ-SD255P

For AJ-SD255E

1 If the audio of the input data is 32 kHz/4CH, CH1/CH2

and CH3/CH4 can be selected in setup menu No. 889
(DIF AUD IN).

The format for IEEE1394 digital output data is determined
based on the setup menu No. 881 (DIF TYPE) setting and
playback tape (mode).

For AJ-SD255E:

Be absolutely sure not to defeat the
following safeguards when connecting the
IEEE1394 cable.

• Ensure that the unit and all devices to be connected

are grounded (or connected to a common ground).
If the equipment cannot be grounded, first turn off the
power of all the connected devices, and then
disconnect and re-connect the IEEE1394 cable.

• When connecting the unit to a device equipped with a

4-pin connector, connect the unit’s connector (6-pin
type) first.

• When making a connection to a PC equipped with a 6-

pin connector, connect the 1394 cable so that it mates
properly with the 1394 connector. Bear in mind that if
the plug is inserted the wrong way round, the unit may
be damaged as a result.
