OUT —
Power ON/OFF Switch. (POWER)
Camera Input Connectors
(CAMERA IN 1/2/3/4)
Accept
the
multiplexed
camera
signal
from
the
Receiver
WV-RC100/WV-RC150.
(Via the System
Controller /WW-CU254)
When no coaxial cable is connected to the Camera
Output Connectors (3), the multiplexed camera signal
is terminated with 75 ohms.
Camera Output Connectors
(CAMERA OUT 1/2/3/4)
When the coaxial cable(s) with the BNC connector(s)
is (are) connected
to this (these) connector(s),
the
multiplexed
camera
signal(s)
fed
to the
Camera
Input
Connectorís)
(2) is (are)
obtained
at
this
(these) connector(s) for other unit(s) of WJ-DA450 or
WV-CU254 by looping through.
Video Output Connectors
(VIDEO OUT 1/2/3/4)
The
camera
video
signals
separated
from
the
multiplexed
camera
signals
are
obtained
at this
connector.
Note:
The control data signal is contained in the vertical
blanking period of the output video signal.

Audio Output Connectors
(AUDIO OUT 1/2/3/4)
The audio signal separated (Demodulated) from the
multiplexed
camera
signals
are
obtained
at this
connector,
Cable-loss Compensatlon Switches
(CABLE COMP, 1/2/3/4, L/M/S)
These switches
are used to set the most suitable
position
of the
cable-loss
compensator
for each
camera
input signal.
The video output signals at
the Video Output Connector (4) compensated beside
that of the Camera
Output Connectors
(3) are not
compensated at all.
The suitable switch position and its approximate cable
length are.as follows.
S:
upto 400m
M:
400
mto 700m
L:
700 m to 900 m
(with RG-59U (BELDEN 9259 or equivalent)
CAUTION :
Reter to page 4 for system connection and ¡ts
maximum cable length.
