Overview
Overview
Pr oduct Features
The CCU-TX7/TX7P is a camera control unit that
connects to DXC-637 Series and DXC-D30 Series
Color Video Cameras via the CA-TX7/TX7P Camera
Adaptor.
This product’s features are described below.
Full-featured signal transfer functions
•The CCU-TX7/TX7P is able to transfer wideband
component video signals. (Y signals at 9 MHz or
above, and R–Y and B–Y signals at 4.5 MHz or
above)
•When using a triaxial cable, audio signals can be
transferred up to 750 meters (2461 feet) (when cable
diameter is 8.5 mm (
11
/ 32
inch)) or 1,500 meters (4921
feet) (when cable diameter is 14.5 mm (
19
/ 32 inch)).
•Transfer functions are provided for the following
signals.
Return video, teleprompter signal, microphone audio,
program audio, red tally and green tally signals
•An intercom switch is also provided.
Flexibly adaptable camera control functions
•The optional COU-TX7 Camera Operation Unit,
which can be installed on the CCU-TX7/TX7P’s
front panel, enables video camera operations to be
controlled from the CCU-TX7/TX7P.
•When several CCU-TX7/TX7P units are connected in
parallel, the optional RCP-TX7 Remote Control
Panel can be used to control video camera operations
as well as the color balance between cameras.
•An RS-232C connector is provided for the CCU-
TX7/TX7P, allowing a personal computer to be
connected for computer-based control of video
camera operations.
Wide array of input/output signals
The input and output connectors provided for the
CCU-TX7/TX7P include those for outputting such
signals as a composite video signal (VBS), component
video signals (switchable to RGB), SDI signals, and
video signals for video and waveform monitors, for
inputting a reference signal for external
synchronization.
Rack mountable
Two CCU-TX7/TX7P units can be installed side by
side in the optional RMM-TXC7 Rack Mount Bracket.

Location and Function of Parts
Use and storage locations
Avoid using or storing the unit in the following places:
•Where it is subject to extremes of temperature
(operating temperature: 5°C to 40°C (41°F to
104°F)).
Note that in summer the temperature in a car with the
windows closed can reach 50°C (122°F).
•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.
Notes on Use
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 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.
