Camera Output connectors
(CAMERA OUT 1–16)
The video signal connected to the CAMERA IN connec-
tor is supplied at these connectors.
When the power of the matrix switcher is turned off, no
signal is supplied at these connectors.
y
Camera Input connectors (CAMERA IN 1-16)
• Connect to cameras or camera site accessories.
These connectors accept either a composite colour or
B/W video signal from a camera.
In addition, the VD2 signal to synchronize the vertical
timing of the cameras, and data to control camera site
devices are multiplexed at these connectors.
• When applying the master-slave connection, the func-
tions of connectors will differ.
u
Termination selector (TERM ON/OFF)
When you connect a PS·Data system controller to the
DATA 4 port, this selector turns the unit's termination
switch to ON/OFF.
The factory default setting is ON.
Note:  When you connect a terminal-mode system con-
troller to the DATA 4 port, set this selector to ON.
i
Alarm port (ALARM)
Connects to alarm sensors.
Accepts the alarm input from the associated alarm sen-
sors.
o
Data ports (DATA 1/2/3/4/DATA HDR)
• DATA 1 to 4 connect to the system controller.
DATA 1 to 3 can connect to RS-485 cameras with the
configuration in WJ-SX155 Administrator Console.
DATA 4 can connect to the system controller via the
PS·Data protocol.
• DATA HDR connects to a recorder.
• When applying the master-slave connection, the func-
tions of ports will differ.
!0
Serial port (SERIAL)
Connects to a PC for the system configuration through
Administrator Console.
!1
RS-485 Camera port
• Connects to an RS-485 camera.
Daisy chain connection is also available.
• When the unit is used as Master in the master-slave
connection, terminal-mode system controllers can be
connected.
Note: To connect terminal-mode controllers, the setting
in SETUP MENU and Administrator Console is
required.
!2
Line selector (LINE SELECT 2/4)
Lets you select either full duplex (4 lines) or half duplex
(2 lines) for RS-485 cameras.
!3
Camera Switching Input connector 
(CAMERA SW IN)
The camera switching pulse from the time lapse VCR
(VTR) is supplied to this connector.
The camera switching interval (Sequential Dwell Time)
can be synchronized with the time lapse mode set in the
associated time lapse VTR.
!4
External Output connector 
(EXT OUT/REC OUT) 
The recording signal for the recorder is provided via this
connector.
!5
External Input connector (EXT IN/PLAY IN)
A playback or live images from the recorder are supplied
to this connector.
!6
Monitor Output connectors (MONITOR OUT 1/2/3/4)
• Connect to monitors.
The video output signals are supplied to the monitors at
these connectors.
• When applying the master-slave connection, the func-
tions of connectors will differ.
!7
Power switch (POWER)
Turns the power of the matrix switcher on and off.
!8
AC Inlet socket (AC IN)
To use the unit, plug the power cable (supplied as a
standard accessory) into this socket and connect it to an
AC outlet.
!9
Cooling fan
Note: Fan unit needs replacement after around 30 000
hours of operation.
