High Speed Serial Data
Transmission
10-bit quantized data can be transmitted at
high speed via serial data transmission, using
triax cable. This offers the benefits of
smooth, real-time control and instant tactile
response from remote control devices.
High Quality Triax
Transmission
The CCU-TX7 system uses analog compo-
nent video transmission (9 MHz bandwidth
for luminance and 4.5 MHz for chromi-
nance). Maximum cable length is 1500m
(5000´) with return video via ø14.5mm
triax cable (Fujikura), 1125m (3750´) via
Sony ø (13.2mm) cable (Mohawk, Belden)
and up to 750m (2500´) via Sony ø
(8.5mm) cable (Mohawk, Belden, Fujikura).
A teleprompter video channel can also be
transmitted through the same cable.
AC/DC Operation
Can operate on AC or 12v DC power. DC
operation greatly expands system flexibility
in field production truck applications.
Two Return Video Inputs
The CCU-TX7 has two return video inputs
(BNC) to accept return video from two dif-
ferent sources. At the CA-TX7 Camera
Adapter end, two channels of return video
can be selected.
Multiple Video Outputs
In addition to two composite video outputs,
the CCU-TX7 has two outputs selectable
from component, RGB and S-Video. There
is also a 4-pin WF (waveform monitor)
mode connector for flickerless parade moni-
toring of signals, in addition to WF and
PIX (picture monitor) output.
Teleprompter Compatible
Can also be used with color teleprompter
systems. Since reverse signal transmission
(CA->CCU) is supported using a
teleprompter video channel in a triax cable,
it is also possible to transmit video signals
other than those for teleprompter from CA
to CCU, if necessary.
Program Mic System
The CCU-TX7 and CA-TX7 are equipped
with a two-channel microphone system.
Two XLR connectors on the CA-TX7 pro-
vide balanced Audio CH-1 and CH-2
inputs, with microphone phantom power
available for an external microphone. The
MIC input Gain of each channel can be
controlled within a range of ±12 dB in 16
steps, by rotary switches on the internal
board of the CCU-TX7.
SONY
CCU-TX7 Camera Control Unit
The CCU-TX7 is a compact CCU designed to be the core of the Sony
Triax Camera Control System for the DXC-D30 and the DXC-637
cameras. The system offers many features and functions designed for oper-
ational convenience and versatility – in addition to the inherent benefits
of a triax system itself—camera control up to 5000 feet with lightweight
cables.
The CCU-TX7 can run on AC or 12v DC power. It outputs composite,
Y/C, component and RGB. It offers a program audio and bi-directional
intercom system (compatible with 2-wire, 4-wire, Clearcom and RTS sys-
tems), in addition to the two-channel XLR outputs from the microphone
inputs on the CA-TX7. A coaxial input is provided for standard BNC
cable use where triax cable cannot be used. And to meet the demands of
various situations, it has two inputs for return video, allowing video sig-
nals from two different sources to be sent to the camera. It supports a
teleprompter system as well.
Supporting the CCU-TX7 are the COU-TX7 Camera Operational Unit,
the RCP-TX7 Remote Control Panel, and the CA-TX7 Camera Adapter.
By combining these peripheral products, the best system can be easily set
up for each application.
