(signal ground) terminal
For signal ground.

REF IN (reference input) connectors (BNC type)
There are eight connectors with loop-through function
for four signals (A, B, C, and D). The connectors
accept analog reference video signals (black burst
compatible with CCIR624 standards or tri-level sync
for HDTV).
Two connectors of each pair have internal loop-
through connections. If loop-through output signals
are not used, terminate any connector that is not used
with a 75-ohm terminator.
Note
If you wish to synchronize signal switching with a
reference video signal, set the timing of signal switching
(odd or even field) and select reference video signal A,
B, C, or D on the PC (terminal emulator).
For further details, refer to the installation manual and
system setup manual.
7 REMOTE 1 connectors (BNC type)
There are five connectors for four signals, A, B1/B2,
C, and D (two connectors for B).
Connect the remote control unit and routing switchers
using a single coaxial cable to control the system via
S-BUS protocol. When you use this switcher as the
primary station
1)
(set the internal P/S switch to P), a
maximum of 253 remote control units and routing
switchers can be connected via these three connectors.
When you use this switcher as a secondary station
1) (set
the internal P/S switch to S), connect an S-BUS
link to one of the connectors using the supplied
T-bridge (type B).
See “System Connection Example” on page 9(E).
Note
Put the supplied 75-ohm terminator(s) on the unused
connector(s) regardless whether it is the primary
station or secondary station.
8 REMOTE 2 connectors (D-sub 9-pin)
There are two connectors for signals A and B.
Connect an external control unit using a Sony 9-pin
remote control cable for use via the RS-422A
interface.
1)Remote control operations via S-BUS protocol consist of
a data link constructed using a single coaxial cable link.
Several pieces of equipment (i.e. routing switchers,
control units, etc.) are connected to this data link for data
transmission in time-sharing mode. One of the connected
When the unit is specified for the primary station,
S-BUS Convert mode is selected and S-BUS control
via the REMOTE 2 connector is enabled.
For details, refer to the system setup manual.
9 REMOTE 3 connector (D-sub 9-pin)
If the switcher is used as the primary station
1)
(internal
P/S switch set to “P”), connect the control terminal to
perform the settings required for system operations.
Use the D-sub 9-pin connectors with inch screws for
connections.
Note
If you are using the REMOTE 3 connector, set the
S702-2 switch on the CPU-339 board to the P position.
For further details, refer to the installation manual.
0
ALARM connector (Mini D-sub 15-pin)
To output the status of the switchers in the same
condition as the status indicators on the front panel.
For details, see “Specifications” on page 17(E) and refer to
the installation manual.
qa DATA connector (modular jacks)
Connect to the Ethernet connector of the PC in which
the supplied BZR-20 has been installed.
CAUTION
For safety, do not connect the connector for peripheral
device wiring that might have excessive voltage to this
port. Follow the instructions for this port.
ATTENTION
Par mesure de sécurité, ne raccordez pas le connecteur
pour le câblage de périphériques pouvant avoir une
tension excessive à ce port. Suivez les instructions
pour ce port.
VORSICHT
Aus Sicherheitsgründen nicht mit einem
Peripheriegerät-Anschluss verbinden, der zu starke
Spannung für diese Buchse haben könnte. Folgen Sie
den Anweisungen für diese Buchse.
CAUTION
When you connect the DATA connector of the unit to
peripheral device, use a shielded-type cable to prevent
malfunction due to radiation noise.
switchers is used as the primary station that manages the
use of the data link, while the other equipment is used as
secondary stations which follow directions from the
primary station. The response speed may slow down due
to the number of secondary stations.
