Overview
The DVS-128 hybrid routing switcher is newly
designed with optional BKDS-series unit/boards to
provide a matrix switcher system which can handle
multiple signal formats for broadcasting. It can
configure a matrix size of 128 × 128 at maximum in
units of 32 channels for analog audio, analog video and
digital audio signals in a single enclosure.
Operations of the DVS-128 system are controlled by
an external controller, such as the optional BKSR1607/R1608/R3209/R3210 control units, which
perform the actual signal switching. Also, to operate
this switcher, a terminal emulator on a PC is required
for the switcher settings (i.e. table data creation and
system settings).
The operating status and errors of the DVS-128 system
can be easily monitored using the ISR (Interactive
Status Reporting) system, which provides status
reporting on equipment used in broadcasting and
production houses with a computer.
For details on the ISR system, refer to the installation
manual.
Mutual exchange between analog and digital
audio boards
While the DVS-128 system can simultaneously operate
matrix switchers of different signal formats, analog
and digital signals can be exchanged between the
optional analog and digital audio (AES/EBU) boards
as they conform to the same signal formats,
Input analog audio (stereo) signals can be output as
digital audio signals, or vice versa.
Thus, future shifting from an analog audio system to a
digital audio system can be easily accomplished.
You can also easily monitor digital audio signals.
Dual reference signals
The DVS-128 has two input connectors each for video
reference and audio reference (audio word sync),
which can be independently selected for each signal
matrix.
You can use, for example, the house sync of a
broadcast station for one matrix and another reference
of different phase and frequency for another matrix in
a single enclosure.
Features of the Hybrid Routing
Switcher
Multiple signal formats
The DVS-128 system can handle analog audio, analog
video and AES/EBU digital audio signals with the
appropriate optional boards installed, which have
inputs or outputs in units of 32 channels in the DVS128 switcher enclosure.
As the DVS-128 system can simultaneously enclose
multiple boards of different signal formats in a single
enclosure, you can integrate conventionally separated
switching devices into a single unit.
Matrix size of 128 × 128 at maximum
As the system can handle inputs and outputs of 128
channels each at maximum, you can establish, for
example, a 64 × 32 digital audio signal matrix and a 64
× 96 analog audio signal matrix in a single enclosure.
Redundant CPU and power unit
For the control board and power supply unit that are
essential for every broadcasting device and must be
highly reliable, a backup CPU board and power supply
unit are available as options.
Sony S-BUS control formats
The system employs the Sony S-BUS control format,
which enables operation control via a single coaxial
cable. Complicated daily operations can be achieved
via a single coaxial cable line.
Newly developed software specifications
This system conforms to new software upgraded in the
controllable matrix sizes and control items from the
conventional routing switcher control software. The
principal upgrades are as follows:
•Handling of 1024 × 1024 (8 levels) or 1024 × 512 (16
levels) is enabled.
•Up to 2048 sixteen-character “Description names”
can be registered.
•Up to 32 “type names” can be used.
• The number of group factors for tie-line management
is expanded to 255.

Control using S-BUS protocol
S-BUS is a protocol developed by Sony for control of
a digital routing switcher system. This protocol
enables communication between multiple routing
switchers and control units using one coaxial cable. A
combined total of 254 routing switchers, control units
and equivalent devices can be controlled using S-BUS
protocol.
Control using RS-422A protocol
The DVS-128 has the capability to convert RS-422A
commands to S-BUS commands. The mode that
controls signal in their original form using RS-422A
commands is known as direct mode and the mode that
converts RS-422A commands to S-BUS commands is
known as S-BUS convert mode. S-BUS convert mode
can control up to eight levels, however the response
speed is slower than in direct mode. Also, the items
that can be controlled in S-BUS convert mode are
limited to the items possible for control in direct mode.
Simultaneous control of multiple signals with
the level setting
To simultaneously handle several types of signals,
each type of signal requires a different routing
switcher. These are known as levels. For example, a
VTR requires video, audio, time code, and remote
control signals for recording. To switch these signals,
these signals require video, audio, time code, and
remote routing switchers respectively. You can set a
maximum of sixteen levels and different input signal
numbers on each level in order to simultaneously
control these levels.

Overview
Functions of the Hybrid Routing
Switcher
This routing switcher system is equipped with the
following functions.
Designated input and output line protect
function
This function prohibits the switching of protected
output signals from other control panels (protect
function) and protects the designated crosspoints by
hiding the input signals from all control panels and in
turn prohibiting switching from other control panels
(secret function).
Crosspoint disable function
For every output signal, you can limit the input signals
available for selection so that any particular input
signals can be output to the specified output lines.
Password function
You can enter a password to prevent unauthorized
users from accessing the system.
Name setting function
You can set names for each input and output connector
in order to distinguish among the connected signals.
Two methods are available for setting the names;
either enter the device name and number (i.e. name of
the VTR, camera, etc.), for example VTR 1, or a
description using up to 16 characters. You can display
the name on the optional BKS-R3280/R3281 display
units and BKS-R1607/R3210 control units.
Virtual mapping function
You can set crosspoints on a virtual matrix.
Free assignment function
You can assign a different connector number to a
connector name on each level.
Monitoring function
You can use the optional BKS-R1607/R1608/R3209/
R3210 control units (version 3.00 or higher) to monitor
output signals.
Phantom function
You can switch several crosspoints at the same time.
Self-diagnosis function
You can send and display information about whether
an error has occurred or not to the terminal connected
to the primary station.
Functions of an S-BUS System
An S-BUS control system transmits the control signals
among several routing switchers and control units that
are connected with one coaxial cable. In an S-BUS
control system, one switcher is designated as the
primary station which controls the entire system, and
the remaining switchers and control units are
designated as secondary stations. Signal transmission
between the secondary stations is controlled by the
primary station.
The S-BUS control system has the following features.
•LAN (Local Area Network) type control signal
transmission using a single 75-ohm coaxial cable.
•Possible extension of the coaxial cable up to 500
meters when a BELDEN 8281 or equivalent cable is
used.
•Possible connection and disconnection of a switcher
or control unit to the S-BUS line during normal
operations without turning the power off.
•Control of multiple S-BUS lines and up to 254
switchers and control units (including the primary
station) from the routing switcher designated as the
primary station.
•Possible connection of a maximum of 128 routing
switchers and control units to one S-BUS line.
•Display of the errors detected through the selfdiagnosis function on the PC (terminal emulator)
connected to the primary station on the S-BUS line.
•Storage and future recovery of the settings (system
settings and table data) made with the PC (terminal
emulator) and the crosspoint data in/from a computer
using the supplied BZR-20 Backup Software.
Tie line function
You can enable the system to automatically select the
signal line that connects two or three routing switchers.

Error Indications and Countermeasures
This switcher performs self-diagnosis testing when you
turn the power on or reset the switcher, and at regular
intervals during operation. If the self-diagnosis test
detects an error, the status indicator lights, and
information about the error is output to the terminal.
The information about the error is also output to the
host computer of the ISR system if this switcher is
connected to the system.
through the 2-digit error code shown on the ERROR
No. indicator on the CPU-275 board.
The errors that may be displayed on the switcher and
their respective countermeasures are shown in the table
below.
Refer to the maintenance manual for information
concerning the error codes displayed on the ERROR No.
indicator and the appropriate countermeasures.
You can easily determine the origination of the error
