Overview
Control of a Digital Routing
Switcher System
In the digital routing switcher system, a control unit
controls the signal switching in accordance with the
settings of a terminal. There are two types of control
available for you to control the routing system and
both can be used simultaneously. These are S-BUS
protocol which is used through the BNC type
REMOTE 1 connector, and RS-422A protocol which
is used through the D-sub 9-pin REMOTE 2
connector.
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 and control
units can be controlled using S-BUS protocol.
The DVS-V3232M also has the ability to convert RS-
422A protocol commands to S-BUS commands which
allows for additional S-BUS control through the D-sub
9-pin REMOTE 2 connector.
Control using RS-422A protocol
The DVS-V3232M can be controlled with any of the
three types of RS-422A protocol that is employed in
Sony equipment. This switcher also has the capability
to convert RS-422A commands to S-BUS commands.
The mode that controls signals 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 expand the amount of signals
for control to a maximum of eight levels of 256 input
and 256 output signals, however the response speed is
relatively slower than that 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.

Functions of Digital Routing
Switcher System
The digital routing switcher system is equipped with
the following functions.
Designated input and output line protect
function
This function prohibits the switching of the 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 certain 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 to set 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
unit, and BKS-R1607/R3205/R3206/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 an optional BKDS-V3292M monitor
board to monitor input and output signals.
Tie line function
You can enable the system to automatically select the
signal line that connects two or three routing switchers.
