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 active through output 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) Y / G / C1 (HD/SD,
ANALOG OUT)
The signal input from (1) is D/A converted and output from (2), (3),
(4), and (5). The Y (HD/SD component), G (RGB component) or
composite signal can be output from this connector (2).
(3) PB/ B / C2
(HD/SD,
ANALOG OUT)
The signal input from (1) is D/A converted and output from (2), (3),
(4), and (5). The PB(HD/SD component), B (RGB component),
Y(Y/C) or composite signal can be output from this connector (3).
(4) PR/ R / C3
(HD/SD,
ANALOG OUT)
The signal input from (1) is D/A converted and output from (2), (3),
(4), and (5). The PR(HD/SD component), R (RGB component), C
(Y/C) or composite signal can be output from this connector (4).
(5) SYNC / C4 (HD/SD,
ANALOG OUT)
The signal input from (1) is D/A converted and output from (2), (3),
(4), and (5). The composite, bi-level sync, or tri-level sync signal can
be output from this connector (5).
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).

 Analog output selection 1 ( SW2-1, 2 )
Selects an output signal format for the connectors Y/G/C1, PB/B/C2 and PR/R/C3 (see
section 4-3-1). Only YPBPRor GBR can be selected if an HD-SDI signal is input to the unit.
 Analog output selection 2 ( SW2-3 )
Selects an output signal format for the SYNC/C4 connector.
Only SYNC can be selected if an HD-SDI signal is input to the unit (see section 4-3-1).
 Output selection when signal not present ( SW2-5 )
Selects black video or no video output from 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 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 can be output in synced with the input signal if an HD/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. Note that the unit may not output test signals correctly if manually selected
format does not match with the input signal. 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 cannot be performed during test signal output.
