*** HDC-930 only supports interlace formats.
Optical Fiber Digital Transmission
The cable connecting the HDCU-900/950 CCU to an 
HDC- 900 or HDC-950/930 camera uses two single-
mode optical fiber lines, two control lines, and two 
power lines to carry digitized video, audio, control 
signals and power to the camera. An extremely high-
quality, all-digital bi-directional video and audio signal 
can be transmitted up to a distance of 3 km (1.86 
miles)* with the HDCU-900 and up to 1.2 km (0.75 
miles)* with the HDCU-950. This cable and connector 
conforms to the SMPTE standard.
* When supplying power to the camera via the optical fiber 
cable, the maximum cable length varies with the camera 
system configuration and lens type, the size of the optical 
fiber cable and the number of cable connectors.
Safety Oriented Power Supply
As safety is a major design concept of every Sony 
design, the HDCU-900/950 continuously checks the 
camera cable for open or short circuits. An alarm is 
given if a fault is found and some appropriate 
precautionary actions taken, case by case.
An additional safety feature is that a low voltage is 
initially supplied from the HDCU-900 optical fiber 
connector when the unit is switched on. Only when the 
system check has verified that an appropriate camera 
is connected is the normal operating voltage output.
Locking to External Reference Signals
The HDCU-900/950 can be locked to an external 
reference signal. Either a HD tri-level sync signal 
(according to SMPTE 240M), or an SD black burst 
signal can be used as the reference signal.
RCP-750/751, Remote Control Panels  
Two types of RCP-750 Series Remote Control Panels 
are also available, providing a range of control 
functions from the basic to very sophisticated for 
operational adjustments of an HDC-900/950/930. Each 
type is available with either a joystick or dial type iris 
control.
RM-B750, Remote Control Unit  
The RM-B750 Remote Control Unit has been designed 
to establish a highly mobile and fully controllable 
camera system in the field by integrating control 
capability equivalent to a Master Set-up Unit into a 
compact unit powered from the device to be 
controlled.
The RM-B750 can be connected directly to the any 
HDC- 900 Series camera, attached to the half-rack 
HDCU-950 Camera Control Unit or connected to an 
HDW-250 portable VTR used with these components. 
The combination of an LCD touch-panel screen and 
direct push buttons enables full parameter adjustment 
of the camera to be controlled. When necessary, basic 
tape transport functions of a portable VTR can be 
controlled*. For further operational convenience, the 
RM-B750 has a Memory Stick
®
 media card slot so that 
various setup parameters can be stored and 
transferred between camcorders.
* VTR REC START/STOP can also be assigned by the 
assignable switch.
CNU-500 and CNU-700, Camera Command Network 
Units
The CNU-700 and CNU-500 Camera Command 
Network Units form the technical “nerve center” of a 
star-shaped camera control network, providing 
communication between all the units in the system. A 
RISC-based microprocessor system provides high-
speed transfer of command signals to the HDCU-900/
950 CCU for rapid response. The CNU-500 is for use 
in systems with up to six cameras and the CNU-700 is 
for use in larger systems. One CNU-700 can also 
control six cameras, but can be expanded to control 
up to 12 cameras when fitted with an optional 
expansion board. Several CNU-700 units can be 
connected to the camera control network in a large 
system. 
HDVF-C700W and HDVF-C750W, Multi-format LCD 
HD Color Viewfinders
The viewfinders developed for the HDC-900 and HDC-
950/930 cameras are of a new, innovative design that 
is based on a 6-type TFT color LCD panel providing a 
resolution of 960 pixels horizontally x 540 pixels 
vertically. These viewfinders feature very low power 
consumption and, as they are very compact, their 
panning and tilting angles are greater than those of 
CRT-based viewfinders. The HDVF-C700W is for use 
with the HDC-900 camera and the HDVF-C750W for 
use with the HDC-950/930 portable camera.
* The liquid crystal display fitted to this unit is manufactured 
with high precision technology, giving a functioning pixel 
ratio of at least 99.99 %. Thus a very small proportion of 
pixels (at most 0.01 %) may be “stuck”, constantly on or 
constantly off. In addition, over a long period of use, because 
of the physical characteristics of the liquid crystal display, 
such “stuck” pixel may appear spontaneously. These 
problems have been kept to an absolute minimum, but are 
an unavoidable characteristic of liquid crystal technology.
HDVF-700A and HDVF-20A, CRT-based Viewfinders
The monochrome CRT-based viewfinders, HDVF-
700A (7-type) and HDVF-20A (2-type), can also be 
used with the HDC-900/950/930.
