Long-distance transfer
Electrical shock prevention function
The CA-TX7/TX7P Camera Adaptor, which is docked with a DXC-D30/
D30P or DXC-637 series Color Video Camera, allows connecting the
camera to the CCU-TX7/TX7P Camera Control Unit via a triaxial cable.
This unit enables transfer of Y, R–Y and B–Y signals for high picture
quality.
The maximum triaxial cable length that can be used to connect this unit to
a camera control unit is max. 750 m (when using a Belden ø8.5 mm cable)
or 1125 m (when using a Belden ø13.2 mm cable).
To prevent electrical shock, this unit shuts off any high-voltage power
supply whenever there is an incomplete connection.
Coaxial cable connection
When necessary, this unit can be connected to a camera control unit via a
coaxial cable.
Variety of input/output connectors
Input/output connectors for the following signals are provided:
•Video signal output for teleprompter
•Return video signal output
•Intercom/program output for connected headset
•Microphone or line-in audio input
•Lens or tripod head control signal output

5 CCU (Camera control unit) connector (CATX7: Kings triaxial connector, CA-TX7P: Fischer
triaxial connector)
Connect a camera control unit via a triaxial cable. In
addition to supporting signal transmission between this
AAAAyA<H.L0.idx>
unit and the connected camera control unit, the triaxial
cable enables this unit to receive its power supply via
the camera control unit.
Using a coaxial cable to connect the camera control
unit
The CCU connector must be refitted to enable
connection of a coaxial cable. Note that connecting a
coaxial cable makes it impossible for this unit to
receive power from the camera control unit. Use a
CMA-8A/8ACE AC Adaptor for AC power sources.
Contact your Sony dealer for more information on refitting
the CCU connector.
6 DATA connector (10-pin)
Outputs control signals for the lens (focus or zoom
control) and the tripod head (panning or tilting) that
are sent from a remote control panel connected to the
camera control unit.
For further information about using this connector, consult
your Sony dealer.
7 DC OUT connector (4-pin)
Use this connector when supplying power (DC 12V,
Max. 12 W) to a WRR-810A UHF Portable Tuner
(supplied separately) or an LCD teleprompter unit.
Note
Never connect a unit that has a power consumption
rating of more than 12 W.
8 DC IN connector (XLR 4-pin)
When connecting this unit to a camera control unit via
a coaxial cable, use this connector for a CMA-8A/
8ACE AC Adaptor (supplied separately). Use the
CCQX-3 DC power cord to connect the CMA-8A/
8ACE to this unit.

Notes on Use
Use and storage locations
Avoid using or storing the unit in the following places:
•Where it is subject to extremes of temperature
(operating temperature: –10ºC to +45ºC (14ºF to
113ºF)).
Note that in summer the temperature in a car with the
windows closed can reach 50ºC (122ºF).
•Very damp or dusty places.
•Where rain is likely to reach the unit.
•Places subject to severe vibration.
•Near strong magnetic fields
•Near transmitting stations generating strong radio
waves.
Avoid violent impacts
Dropping the unit, or otherwise imparting a violent
shock to it, is likely to cause it to malfunction.
M4 × 6 screws
Do not cover with cloth
While the unit is in operation, do not cover it with a
cloth or other material. This can cause the temperature
to rise, leading to a malfunction.
After use
Turn the POWER switches on the unit and camera
control unit off.
Care
If the body of the unit is dirty, wipe it with a dry
cloth. For severe dirt, use a soft cloth steeped in a
small amount of neutral detergent, then wipe dry.
Do not use volatile solvents such as alcohol or
thinners, as these may damage the finish.
