1 Status indicators
Indicate the status of the BVS-A3232 by the color of
the indicator and whether it is lit continuously or
flashing. The indicator lights green when the POWER
switch is turned on and operations are normal. When
an error occurs, either the indicator flashes green, or
lights or flashes red.
Thr right indicator functions only when an optional
BKDS-PA3291 backup power supply unit is installed.
See "Error Indications and Countermeasures" on page
11(E) for details about errors.
2 Power switches
Used to turn the power on and off.
3 IN (input) connectors (3-pin)
Accept analog audio signals. These connectors (1-32
CH) can accept a total of 32 signals.
4 OUT (output) connectors (3-pin)
Supply analog audio signals.
5 REMOTE 3 connector (D-sub 25-pin)
Connect a terminal to this connector to perform the
settings necessary for system operations when this
switcher designated as the primary station (set the
internal M/S switch to M).
For monitoring the operating status of this switcher
using the ISR system, connect the ISR system to this
connector.
Refer to the installation manual for futher details on the ISR
system.
Notes
•To use this connector, internal switch setting is
required. Contact the authorized Sony service
personal for switch setting. (Set the S8-8 switch on
the CPU-94 board to the OFF position and the S1-3
switch to the M position.)
For details, refer to the Maintenance Manual.
•Use the D-sub 25-pin connectors with M2.6 screws
for connections.

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

6 REMOTE 2 connectors (D-sub 9-pin)
Connect an external control unit using a Sony 9-pin
remote control cable for use via the RS-422A
interface.
7 REMOTE 1 connectors A, B, and C (BNC type)
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
1)
primary station
(set the internal M/S switch to M), a
maximum of 253 remote control units and routing
switchers can be connected to these three connectors.
When you use this switcher as a secondary station
(set the internal M/S switch to S), connect an S-BUS
link to one of the connectors using the supplied
T-bridge (B) and put the supplied 75-ohm terminators
on the other two connectors.
See "System Connections" on page 7 (E).
8 REF IN (reference video input) connectors
(BNC type)
Accept analog reference video signals (black burst
signals compatible with CCIR624 standards).
Two connectors have internal loop-through
connections. If loop-through output signals are not
used, put a 75-ohm terminator on any connector that is
not used.
Note
Set the S1-1 switch on the CPU-94 board to the SYNC
position if you wish to synchronize signal switching
with the reference signal. Also, set the timing of
signal switching (odd or even field) for the terminal.
Refer to the maintenance manual and installation manual
for further details.
9 y (signal ground) terminal
0 ~AC IN (AC power input) receptacles
Connect to an AC outlet using the optional AC power
cord.
Note
The left onnector functions only when the optional
BKDS-PA3291 backup power supply unit is installed.
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.
