Location and Function of Parts
5CCU (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.
6DATA 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.
7DC 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.
8DC 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.
