!1 Video Input Connectors (VIDEO IN, 1 - 5)
These connectors accept composite video signals from
cameras.
When the Panasonic combination camera is connected
to the VIDEO IN 1 connector, various controls, such as
pan/tilt, zoom, focus and preset, are enabled from the
WV-CU20E Remote Controller connected to the AV
Codec.
The above functions are only available when a camera
equipped with the specified function is connected to
the VIDEO IN 1 connector.
!2 Local Output connector (LOCAL)
The video signals, VIDEO IN 1 - 5, selected by the con-
troller are looped through to this connector.
When the Video Monitor is connected to this, it displays
the camera images at the local site selected by the
controller.
!3 Remote Output Connectors (REMOTE, 1 - 2)
The video signals, that are stored in the internal memo-
ry, are output to these connectors.
When the video monitors are connected to these con-
nectors, the slow motion and poor resolution images
are displayed.
They also enable and disable the image display as
shown below.
REMOTE 1: Enables display, such as setup menu,
clock, etc.
REMOTE 2: Disables all on screen display.
!4 Audio Input Connector (AUDIO IN)
Accepts audio signal from the outboard device. It is
transmitted to the AUDIO OUT connector of the AV
Codec at the destination site.
During transmission, when the AUDIO MUTE button on
the controller is pressed, audio transmission is tem-
porarily interrupted. Press the button again to release
the mute mode.
!5 Audio Output Connector (AUDIO OUT)
Outputs the audio transmitted from the destination site.
Enabling or disabling audio output depends on the set-
tings at the destination site.
The audio input at the local site cannot be to output
through this connector.
!6 Test Switch / Test LED (TEST)
The maintenance (test) switch and LED should not be
manipulated in ordinary operation.
!7 Controller Port (REMOTE)
This port is provided for controlling the AV Codec with
the WV-CU20E Remote Controller.
To connect to the controller, use a 6-conductor modu-
lar cable supplied as an accessory with the controller.

!8 Data Port (DATA PORT)
Accepts a 6-conductor modular cable to exchange
data conforming to an RS-485 interface.
It can be used to establish a system by connecting to
outboard devices.
!9 Setup Switches (SETUP)
These switches are used to select the mode of the AV
Codec, such as line termination.
Refer to the DIP Switch Setting for further details.
@0 0 0 RS-485 Host Port (RS-485 HOST PORT)
This port is used when multiple WJ-AV20 units are con-
trolled with a single control unit (PC, etc.).
@1 RS-232C Host Port (RS-232C HOST PORT)
This port is used when the WJ-AV20 is controlled with a
PC, etc.
Use a crossover cable for connecting to the PC port.
@2 2 Termination Selector (TERM, ON/OFF)
This switch is used to enable termination of the ISDN
line.
Setting to the ON position will make an internal 100 Ω
termination.
@3 ISDN Port (ISDN)
This port is used to connect with an ISDN line, using 8-
conductor modular cable supplied as an accessory
with the AV Codec.
@4 4 Sensor Input / Trigger Output Port (SENSOR
IN/TRIGGER OUT)
This port is used when the AV Codec is used as a
transmitter (remote site).
It enables alarm dialing or camera switching when the
associated alarm sensor is connected to this port.
When the trigger output is connected to an outboard
device, such as a switcher, camera switching is
remotely enabled from the AV Codec.
@5 5 Parallel Port (PARALLEL PORT)
Exchanges 8-bit input and 8-bit output data with the
destination (with strobe output).
This port is also provided with pins so that the signals
shown below can be exchanged.
• Forced Disconnection input
• Time Adjustment input
@6 Signal Ground
@7 AC Inlet Socket (AC IN)
Plug the power cord (supplied as a standard accesso-
ry) into this socket and connect it to an AC outlet.
