2-4. Control System

(Please refer to section 6. Control System for further information)
In addition to the MSU-700 Master Set-up Unit and eight different
types of RCP-700 Series Remote Control Panels, the CNU-700 and
CNU-500 Camera Command Network Units form the command
nerve center for a new concept in camera control system. A wide
selection of control peripherals allow each user to configure the most
suitable system to meet a specific operational need. The following are
the key peripherals.
(a) Master Set-up Unit (MSU-700)
The MSU-700 Master Set-up Unit can control up to 6 cameras (up to
12 cameras by using an expansion board) in combination with the
CNU-700 Camera Command Network Unit. The adoption of an EL
Touch Panel in the MSU-700 helps to simplify the operation of its
sophisticated control system. And data such as scene files can be
11
stored in a world-standard PC memory card.
(b) Camera Command Network Units (CNU-700 and CNU-500)
The Camera Command Network Units are designed to be the nerve
center of the Sony camera control system for the BVP-900 Series,
BVP-700 Series, BVP-500 Series and HDC-700 Series of cameras.
They work as 'Command Selector', 'Command Distributor' and
'Command Arbitrator'. These two types of camera command network
units give a cost/performance choice. The CNU-500 is suitable for
applications with up to six cameras, while the standard six cameras
capability of the CNU-700 can be expanded to 12 cameras with use of
the BKP-7930 optional expansion board. With the BKP-7932 optional
command conversion board installed instead of the BKP-7930, the
CNU-700 can operate with six previous-generation CCU-370/355/350
units as well as six CCU-700A/550 units.
The carefully designed software and the high-speed CPU of both the
CNU-700 and CNU-500 give them a fast response time whatever the
system configuration.
(c) Video Selector (VCS-700)
The VCS-700 Video Selector is used to switch composite video
monitoring signals from a BVP-900 Series multi-camera system to a
picture monitor and waveform monitor. The VCS-700 accepts the
video monitoring signal from up to six CCU-700A or CCU-550
Camera Control Units and switches these signals to two picture
monitor outputs and two waveform monitor outputs. The selection of
monitoring signals can be controlled by the camera selection buttons
on the MSU-700 Master Set-up Unit, or by external control
equipment through the D-sub 37-pin I/O port on the VCS-700.
For SDI monitoring, the optional BKP-7933 S-Bus Interface Board
provides connection to a Sony digital routing system.
(d) Remote Control Panels (RCP-700 Series)
There are four ranges of Remote Control Panel for the BVP-900
Series. Each range has two types - joystick control and dial control.
The RCP-740/741 is the top of the range for sophisticated operational
use, and can be used as a substitute for the MSU-700 Master Set-up
Unit in some special applications. The RCP-730/731 is the mid-range
model with general control function, especially useful for limited
space with its slim design. The RCP-720/721 is also a mid-range unit,
with sufficient control functions for general use. Finally, the RCP-
700/701 features the basic control items required for daily operation
of acquisition camera systems. The RCP-730/731, RCP-720/721 and
RCP-700/701 can all be used as a sub-control panel to support an
MSU-700 or RCP-740/741.

2-5. Viewfinders

As well as the BVF-77/77CE, a high performance 7-inch
monochrome viewfinder with extremely high horizontal resolution,
the BVF-7700/7700P 7-inch high grade color viewfinder is also
available for the BVP-900/900P. This high grade color viewfinder is
especially convenient for cases where color needs to be identified by
the camera operator. For the BVP-950/950P, a 5-inch monochrome
viewfinder, the BVF-55/55CE, is available. All of these models are
very compact in size, light in weight and economical in power
consumption. The low mounting positions of the BVF-77 and BVF-
7700 Series provide convenient viewfinder displays aligned as close
as possible to the lens axis.
