■ Use of external DC power supply
Make sure that the output voltage of the external DC
power supply meets the rated voltage of the unit
before making a connection.
The output current of the external DC power supply
should be large enough to provide the connected
unit with its total amperage needs with a reasonable
margin.
Use the following formula to calculate the total
amperage of the unit.
total power consumption ÷ voltage
When the power is turned on, a rush current occurs. If
the power supply is insufficient during this time, the
unit may be damaged. Therefore, we recommend
using an external DC power supply that provides at
least twice the total power consumed by the unit. We
also recommend using the proper DC cable
recommended for your external DC power supply.
• When using an external power supply other than the
AC adapter, check the DC IN socket pin information
to ensure correct polarity. If a +12 V power supply
is accidentally connected to the GND terminal, this
could cause a fire or personal injury.
◆ NOTE:
• When using an external DC power supply, be sure to first
turn on the power to the DC power supply and then set the
POWER switch on this unit from OFF to ON. If the order of
the above procedure is reversed, this unit will malfunction
since the voltage of an external DC power supply rises
slowly. When the POWER switch of the unit is set to ON, do
not connect or remove a battery or a cable of an external
DC power that is on, to or from the DC IN connector of this
unit. For the same reason as above, failure to heed this
caution could cause the unit to malfunction.
• Inadvertently connecting an input of 18 V or more triggers
an internal protection circuit that shuts down the unit. The
unit will operate normally once the power voltage returns to
normal levels. Be sure not to connect an AC power supply
to this socket.
• When the external DC power supply is connected and set
to on, a minute amount of current will still flow even if the
POWER switch on this unit is set to OFF.

• When using the AJ-YCX250G AVC codec board (optional),
AVCHD material cannot be used as a player even if it is
controlled by an external controller.
TIME CODE OUT connector
Outputs the playback time code during playback.
Outputs the time code generated by the internal time
code generator during recording.
TIME CODE IN connector
Use to record an external time code onto P2 cards.
◆ NOTE:
• The time code from the TIMECODE IN connector cannot be
input when 29.97 is set in setup menu No. 25 (SYSTEM FREQ).
REF VIDEO IN connectors
Input connectors for HD and SD reference video signals.
◆ NOTE:
• It is recommended that this unit be used with a system that
inputs a reference video signal since video and audio
output signals may otherwise deteriorate.
• Input tri-level sync signals with both positive and negative
polarities as HD reference video signals. Input signals that
meet the input signal and data format.
➝ For information on the reference signal, refer to "Example
of Connections in 23.98/24/29.97/25 Hz Mode" (page 41).
• Input a black burst signal that complies with SMPTE170M
and ITU624-4 to use for SD reference video signals.
• When no cable is connected to REF VIDEO OUT connector,
the REF VIDEO IN connector is automatically terminated at
75 Ω. Connecting a cable to this connector releases
75 Ω termination.
• When 59-23, 60-24 or 60-25 is selected in setup menu
No. 25 (SYSTEM FREQ), synchronization is provided only
for playback HD reference signals.
