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  
Do not cover with cloth  
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)).  
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  
Note that in summer the temperature in a car with the  
windows closed can reach 50ºC (122ºF).  
• Very damp or dusty places.  
Turn the POWER switches on the unit and camera  
control unit off.  
• Where rain is likely to reach the unit.  
• Places subject to severe vibration.  
• Near strong magnetic fields  
• Near transmitting stations generating strong radio  
waves.  
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.  
Avoid violent impacts  
Dropping the unit, or otherwise imparting a violent  
shock to it, is likely to cause it to malfunction.
