Overview

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.

Component signal transfer method

This unit enables transfer of Y, R–Y and B–Y signals for high picture quality.

Long-distance transfer

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).

Electrical shock prevention function

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.

1)

Variety of input/output connectors

Input/output connectors for the following signals are provided:

output) connector (BNC type)

Outputs teleprompter video signals

1)

from the camera control unit. (This unit can treat color teleprompter video signals.)

If you have made the internal adjustment to change the teleprompter video signal transfer direction so that signals are transferred from this unit to the camera control unit, this connector becomes the input connector for teleprompter video signals.

Illustration: CA-TX7

Contact your Sony dealer for further information on the internal adjustment to change the teleprompter video signal transfer direction.

Location and Function of Parts

5 CCU (Camera control unit) connector (CA-

TX7: 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 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.

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.
