"TYPE-B".). The unit does not automatically recover when the power comes back on. First turn the POWER switch off, wait a few seconds before turning the switch back on. Pin No. 1 2 3 4 Signal Ground - - +12V 1 2 3 4 ■ 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. 8. Remote control connector This unit can be connected to an external controller to enable remote operation of the unit or connect and control an external device.

TIME CODE OUT connector Outputs the playback time code during playback. Outputs the time code generated by the internal time code generator during recording. 10.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). 11.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. 30 Introduction: Control Reference Guide
