PREFACE
FEATURES
The Data Multiplex Unit WJ-MP204C is designed for instal-
lation in a surveillance system, offering system flexibility
particularly when camera control functions are required. 
The unit multiplexes video signals with control data and
VD2 sync into a coaxial cable. This makes installations
between the unit and cameras easy.
Front Panel Operations
• Camera channel selection from 1 to 4
• Alarm reset/suspension
• WJ-MP204C setup menus 
In/Out Features
• Four camera inputs with multiplexed control and VD2
• Four camera outputs looped through
• Spot (monitor) in/out
• VS/VD (sync) in/out
• RS-485 for use of the Camera Communication Protocol
• RS-485 for use of the PS
•Data protocol 
• Alarm in/out and remote in/out, switchable
Displayed Image on the monitor screen
• Camera channel selected
• Alarm channel activated
• Setup menusCamera control with WV-CU360C
• Pan/tilt head and housing control
• Motorized lens control (focus, zoom, iris, etc.)
• Camera setup menus
Alarm Function
• Inputs: Video Motion Detection by the camera/Alarm
input to the terminal.
• Output: Signal is supplied to respective alarm terminal.
• Preset: The camera moves to the preset position when
an alarm operates.
• Display: The activated channel picture and the channel
number are displayed. The monitor and system controller can be located distant
from the camera site thanks to the use of a coaxial cable
and an RS-485 cable. 
The unit includes two protocols, Panasonic Security Data
(PS
•Data) and the Camera Communication one, selectable
with DIP switches.

PRECAUTIONS
• Refer all work related to the installation of this
product to qualified service personnel or system
installers.
• Do not block the ventilation opening or slots on the
cover.
To prevent the appliance temperature from rising, place
the appliance at least 5 cm (2 inches) away from the
wall.
• Do not drop metallic parts through slots.
This could permanently damage the appliance. Turn
the power off immediately and refer servicing to quali-
fied service personnel.
• Do not attempt to disassemble the appliance.
To prevent electric shock, do not remove screws or
covers.

ance.• Do not expose the appliance to water or moisture,
nor try to operate it in wet areas.
Do take immediate action if the appliance becomes
wet. Turn the power off and refer servicing to qualified
service personnel. Moisture can damage the appliance
and also cause electric shock.
• Do not use strong or abrasive detergents when
cleaning the appliance body.
Use a dry cloth to clean the appliance when it is dirty.
When the dirt is hard to remove, use a mild detergent
and wipe gently.
• Do not operate the appliance beyond its specified
temperature, humidity or power source ratings.
Do not use the appliance in an extreme environment
where high temperature or high humidity exists.
Use the appliance at temperatures within –10°C -
+50°C (14°F - 122°F) and a humidity below 90 %.

@1Camera Input Connector 1-4 (CAMERA IN 1 2 3 4)
These connectors accept the composite video signal
supplied by the cameras while passing through the
control data and VD2 sync signal.
@2Camera Output Connector 1-4 (CAMERA OUT 1 2 3
4)
These connectors supply the looped through composite
video of the camera image. Any one of these connec-
tors can accept VD2 sync from a connected device
such as a Video Multiplexer that accepts composite
video while sending VD2. Refer to page 23 for details. 
@3Spot Input Connector (SPOT IN)
Accepts a spot output signal supplied from another
Data Multiplex Unit when connecting more than one unit
in a daisy fashion.
@4Spot Output Connector (SPOT OUT)
Supplies the composite video signal of the selected
camera, alarm activated camera or WJ-MP204C setup
menus to display them on the monitor. This BNC is usu-
ally connected with a monitor.  In a multi-unit connec-
tion this is connected with SPOT IN of the next unit
unless the unit is at the tail end.
@5VS/VD Input Connector (VS/VD IN)
Accepts C. Sync, VBS or VD sync input. The unit will
follow the sync input while supplying sync through the
VS/VD OUT connector to other devices. Cameras will
follow VD2 sync supplied through the CAMERA IN con-
nectors. You need to set up VS/VD INPUT in the SYS-
TEM menu window when connecting. Refer to page 23
for details. 
Note:Sync source should comply with the EIA RS-170
standard. Do not input signals having a high jitter
content such as VCR playback signals.  @6VS/VD Output Connector (VS/VD OUT)
Supplies a sync signal depending on the input to the
VS/VD IN connector and setting of the MODE DIP
switch #1. Refer to page 15 and 23 for details. 
@7Alarm/Remote Terminal (ALARM/REMOTE)
Pins #6-9 are used in one out of four ways most suitable
to your system requirements: alarm input, alarm output,
remote input, and remote output. Input/output is speci-
fied by the position of an internal connector while
alarm/remote is specified in the SYSTEM setup menu.
Refer to page 16 and 26 for more details.
@8RS-485 Terminal (RS-485)
These terminals are exclusively used for devices com-
patible with “Camera Communication Protocol” such as
the WJ-SX350 Matrix Switcher and WJ-FS616C Video
Multiplexer. Through R (receive) and T (transmit) termi-
nals, the unit exchanges communication data for cam-
era control and other commands in 2-line half duplex or
4-line full duplex mode.
@9Data Port (DATA)
This port is exclusively used to communicate with
devices compatible with “PS
•Data protocol” such as
the WJ-FS316/416 Video Multiplexer, Digital Disk
Recorder and System Controller WV-CU360C. Using
this port is incompatible with using RS-485 terminal
above.   
#0DIP Switch (MODE)
Data communication mode and sync setting are speci-
fied with this switch. Refer to page 15 for more informa-
tion.

Mounting One WJ-MP204C with the 
WV-Q204/1
1. Fix the mounting brackets (large and small) on both
sides of the WJ-MP204C with the eight supplied screws
(M3x8) to the WV-Q204/1.
Mounting two WJ-MP204Cs with the 
WV-Q204/2
1. Place the joint metals on the WJ-MP204Cs as shown
below and fix them with the supplied screws (M3x6) to
the WV-Q204/2.
Note:Remove the two screws from the rear of each
WJ-MP204Cs.
2. Install the WJ-MP204Cs with the rack 
mounting brackets on the rack using 
four screws (not supplied).
Cautions: 
• Do not block the ventilation opening or slots in the
cover to prevent the appliance from overheating.
Always keep the temperature in the rack within +45°C
(113°F).
• Secure the rear of the appliance to the rack by using
additional mounting brackets (procured locally), if the
rack is subject to vibration.
• Do not use tapping screws for installing the WJ-
MP204C on the rack with the rack mounting brackets.
