Overview
By connecting this unit to the multi-format camera (model AK-HC931P), multi-format images can be input and output.  (Some
of the functions are available as options.)
The unit is connected to the multi-format camera, and it is connected to the remote operation panel (ROP) and master setup
unit (MSU) using dedicated multi-purpose cables (available as optional accessories).
When the designated multi-purpose cables are used, the distance between from the CCU to the ROP and MSU can be
extended up to 50 meters.
Accessories
Rack-mounting adapters (k2)
Mounting screws (M4k8 mm) (k6)
BNC termination resistor (k1)
Communication connector (k1)
Power cord (k1)
Operating precautions
OHandle the unit carefully.  
Dropping the unit or subjecting it to strong impact may cause malfunctioning and/or accidents.  
OOperate the unit within a temperature range of 32oF to 104oF (0oC to i40oC).  
Operation in locations below 32oF or above 104oF may adversely affect the internal parts.
OBe absolutely sure to turn off the power before connecting or disconnecting the
cables.
ODo not use the unit outdoors.
OInstall the unit at a distance of at least 3.3 ft (1 meter) from the monitor.
OMaintenance
Disconnect the power plug, and wipe the unit with a dry cloth.  To remove stubborn dirt, soak a cloth in diluted kitchen
detergent and wring it out well, and then wipe the unit gently.
OAvoid using benzine, paint thinners or other volatile substances.
OIf a chemically treated cloth is to be used, read the precautions for its use carefully.

Parts and their functions
1CCU power switch [MAIN]
This is the power switch of the camera control unit
(CCU).  The CCU, ROP and other units will not operate
unless this switch is set to ON.
Up: ON
Down: OFF
2Camera power switch [HEAD POWER]
This switch supplies power to the camera.  However, if
the ROP has been connected, power is supplied to the
camera only when this switch and the camera power
switch on the TOP are both set to ON.
Up: ON
Down: OFF
3CCU power ON LED
Lighted: The CCU power is ON.
Off: The CCU power is OFF.
4Camera power ON LED
Lighted: This indicates that power is being supplied from
the CCU to the camera.
Off: This indicates that power is not being supplied
from the CCU to the camera.
Even if the camera power switch is ON, this LED remains
off if no power is supplied to the camera.
This is due to one of the following reasons: 1the supply
of power to the camera has been turned off by the ROP,
2one of the optical fiber cables has been disconnected
or 3something is wrong with the camera, and the power
supply was turned off.
5CCU power fuse
This is the CCU main power fuse.
6Camera head power fuse
This is the camera head power supply fuse.
7Alarm LED [ALARM]
Lighted:This LED indicates that the CCU’s fan has
stopped and that something is wrong with the
power supply.
Off: Normal 
If the LED remains lighted, turn off the main power and
have the unit repaired.8Camera cable open alarm LED [CABLE / OPEN]
Lighted: The cable between the CCU and camera has
been disconnected.
Off: Normal
9Camera cable short-circuit alarm LED
[CABLE / SHORT]
Lighted: The cable between the CCU and the camera has
short-circuited.
Off: Normal
:TALLY indicator/CALL switch [TALLY/CALL]
This indicator lights when the R/G tally signal is input.  It
is also a CALL switch for calling the camera, ROP and
MSU.
;INCOM volume control [LEVEL]
This is used to adjust the standby INCOM volume.
INCOM selector switch 
This is used to select the call party of the standby
INCOM.
PRIVATE: For making private calls to the camera.
COMM: For connecting the standby INCOM with the
system INCOM.
?INCOM MIC selector switch [MIC]
ON: The INCOM microphone is set to ON.
OFF: The INCOM microphone is set to OFF.
PTTN: The INCOM microphone is set to ON only while
the INCOM MIC selector switch is held down.
@Standby INCOM jack
This is connected to INCOM 1 line, and it enables calls to
be made to the camera’s INCOM 1 line.
Even when the camera power is OFF, calls can still be
made to the camera’s INCOM 1 line.

This connector is for outputting the alarm signals to the
external system when any problem with the supply volt-
age has occurred inside the CCU or the CCU fan has
stopped.
When the power supplied to the AC fan or DC fan inside
the CCU has been shut down, pins 3 and 4 of this con-
nector are shorted.
If power is supplied to the CCU and any of the DC power
supplies inside the CCU fails to output the supply voltage,
it means that pins 1 and 2 of this connector are shorted.
