Control System of the HDS-
X3000-Series Routing Switcher
In the HDS-X3000-series routing switcher system, a
control unit controls the signal switching in accordance
with the settings of a terminal emulator on PC.
There are two types of control available for you to
control the routing system: S-BUS protocol, which is
used through the BNC-type REMOTE 1 connectors,
and RS-422A protocol, which is used through the D-
sub 9-pin REMOTE 2 connectors.
You can use both protocol simultaneously.
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.
The HDS-X3000 series has the capability to convert
RS-422A commands to S-BUS commands, enabling S-
BUS control through the D-sub 9-pin REMOTE 2
connector.
Control using RS-422A protocol
The HDS-X3000 series 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.
HKDS-X3011 SDTV Serial Input Board
(available in the near future)
This is a connector board for 16 inputs.
For each single HKDS-X3010 (32 inputs), two HKDS-
X3011 boards (16 inputs
×
2) can be mounted.
This board can handle SDTV SDI (143 Mbps to 270
Mbps).
