@1 Camera 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.
@2 Camera 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.
@3 Spot 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.
@4 Spot 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.
@5 VS/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.
@6 VS/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.
@7 Alarm/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.
@8 RS-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.
@9 Data 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.

●Alarm/Remote Terminal Setting
The rear of the unit is provided with an 11-pin terminal, ALARM/REMOTE.
Pins from #1 to #5 perform as follows.
Pin #1 supplies an active output for the duration specified by the ALARM OUTPUT in the setup.
The output type is a low-active open collector with a capacity of 16 V DC, 100 mA maximum.
Pin #2 accepts an alarm reset pulse (input) that makes the unit reset the alarm mode.
A no-voltage make-contact is accepted.
Pin #3 supplies an alarm reset pulse (output) when the unit resets the alarm mode.
The output type is 0 V (active)/5 V for the default setting, or a low-active open collector with controllable capacity of 16 V
DC, 100 mA maximum after changing an internal switch (SW 704).
Pin #4 accepts a spot switching pulse (input) from other units in a multi-unit connection.
A no-voltage make-contact is accepted.
Pin #5 supplies a spot switching pulse (output) to other units when the unit selects a new camera channel in a multi-unit
connection.
The output type is a low-active open collector with a capacity of 16 V DC, 100 mA maximum.
Pins #6 to #9 are used in many ways depending on the menu settings and the internal connector settings. If internal adjust-
ments are required, please refer to the Service Manual available for this unit.
