Precautions
Important Safety Warnings
[Power]
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Circuitry Access]
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Consumables]
The consumables used in unit must be replaced periodically. For further details on
which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.

No Name Description
(1)
HD/SD-SDI IN
HD/SD-SDI
OUT
The left connector is used to input a serial digital component signal
(HD/SD-SDI).
The right connector is used to output an active-through out of
HD/SD-SDI IN. The jitter in the active-through output depends on
how much jitter is included in the input video. This card module has
no jitter-reducing function.
(2) SD-SDI OUT
(1 / 2)
Used to output SD-SDI signals.
Signals, down-converted and adjusted by Proc Amp, are output if an
HD-SDI signal is input.
Proc Amp adjusted signals are output if an SD-SDI signal is input.
(3) Y / G / C1
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The Y (HD/SD component), G
(RGB component) or composite signal can be output from this
connector (3).
(4) PB/ B / C2
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The PB(HD/SD component), B
(RGB component), Y(Y/C) or composite signal can be output from
this connector (4).
(5) PR/ R / C3
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The PR(HD/SD component), R
(RGB component), C (Y/C) or composite signal can be output from
this connector (5).
(6) SYNC / C4 (HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The composite, bi-level sync, or
tri-level sync signal can be output from this connector (6).
The FUNCTION (see previous page) on the front panel enables you to select the type of signal
output from HD/SD ANALOG OUT (see also section 4-3).
The SD-SDI OUT and ANALOG OUT connector output a down-converted signal and/or a signal
input from HD/SD-SDI IN. The available output signal formats of these two outputs for different
input signal formats are as shown in the table below. The unit may not output signals correctly if
any other signal format than those listed below is used to input to the unit.

 HD/SD analog output selection ( SW2-4 )
Selects HDTV or SDTV for analog output.
HDTV cannot be selected when the SD-SDI signal is input to the unit, or when Y/C or
Composite is selected for Analog output selection 1 (see section 4-3-1).
 Output selection when signal not present ( SW2-5 )
Selects black video or no video output from SD-SDI OUT and ANALOG OUT when input
signal is not present. No signal will be output from HD/SD-SDI OUT (active through)
regardless of this setting when input signal is not present.
 Internal test signal ( SW2-6 )
Outputs a test signal (Color Bar or Cross Hatch) from SD-SDI OUT and ANALOG OUT if set
to ON. However, the test signal is not output from HD/SD-SDI OUT (active through). Use
dipswitch SW6-8 to select test signal between Color Bar and Cross Hatch. (See section 5-1)
The test signal of both HDTV and SDTV can be output in synced with the input signal if an
HD-SDI signal is input to the unit. The test signal of SDTV can be output in synced with the
input signal if a SD-SDI signal is input to the unit. Select the test signal format manually by the
SW6 switch setting if any signal is not input to the unit. If set to Auto Detection and any signal
is not input to the unit, the last used signal format is selected for the test signal (see section
5-1). Proc Amp controls and aspect conversion cannot be performed during test signal
output.
