REMOTE 2 connectors A and B (D-sub 9-pin)
Connect an external control unit using a Sony 9-pin
remote control cable for use via RS-422A interface.
Set the switcher to S-BUS convert mode with the
terminal to enable S-BUS control using these
connectors. If you set the switcher to THROUGH
mode, the control signal accepted by connector A is
output from connector B in the original form and can
be sent to the other routing switchers or control units.
Refer to the installation manual for further details.
8
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
primary station
1)
(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
1)
(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 “Example of System Connections” on page 8(E).
9
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 S4-1 switch on the CPU-149 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) with the
terminal.
Refer to the maintenance manual and installation manual
for further details.

AC IN (AC power input) receptacles
Connect to an AC outlet using an AC power cord.
Note
Receptacle B functions only when the supplied BKDS-
V3291M backup power supply unit is installed.
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
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 the directions from the
primary station. The response speed may slow down due
to the number of secondary stations.
