@1 Video Input [VIDEO IN 1, 2, 3, 4]
Connect a maximum of four Panasonic’s Combination
Cameras in the Remote site where the unit is set to
Transmitter mode. These BNC receive composite video
signals from the cameras while the control commands
(e.g., pan/tilt, focus, etc.) pass through these terminals.
This will be used only for the Remote site.
@2 Auxiliary Video Input [AUX IN]
Connect an ordinary camera rather than a Combination
Camera, or an image reproduction device such as
Digital Disk Recorder, VCR and so forth with this BNC.
This BNC is used at the Remote site where the unit is
set to Transmitter mode. This will be used only for the
Remote site. The image supplied to the AUX IN will not
be output to the MONI/SPOT terminal on the Remote
site, however it is transmitted to the Control site.
@3 Audio Input [AUDIO IN]
Accepts audio signal from the outboard device. Audio
is transmitted to the other site. Audio transmission can
be interrupted if you press the MUTE button on the
Remote Controller. Press it again to resume the trans-
mission.
@4 Video Output [VIDEO OUT 1, 2, 3, 4]
Video In signal 1-4 are looped through to these BNC in
the Remote site. If connected, make certain to termi-
nate at the connected device with a 75 Ωresister
because the automatic termination will be released in
the unit. This will be used only for the Remote site.
@5 Monitor/Spot Output [MON/SPOT]
This BNC little changes in function depending on the
unit setup to a Receiver or a Transmitter.

Outputs audio signal supplied from the other site.
Audio transmission is enabled or disabled depending
on the setting conditions at the other site.
@7 Sensor Input/Trigger Output [SENSOR IN/TRIGGER
OUT]
A D-Sub 25-pin connector has 8 inputs and 8 outputs
for sensor-related wiring. This is used only for the
Remote site.
A SENSOR IN terminal receives the signal from the
connected sensor that is installed in conjunction with
the camera position or its aiming position. A TRIGGER
OUT terminal relays the sensor input information to the
connected device such as Hard Disk Recorder, Video
Multiplexer, etc. These devices will enter alarm record-
ing mode accordingly. The Network Interface unit, fol-
lowing the setup, will enter Alarm Dialing or Camera
Switching when the sensor input comes in. The TRIG-
GER OUT terminal also supplies the VIDEO SWITCH
selection information. See page 24-26 for connection
and specifications.
@8 Parallel Port [PARALLEL PORT]
A D-Sub 25-pin connector has parallel inputs and out-
puts for auxiliary control purposes with optionally
installed switches and other devices. The following 3
functions perform on the unit basis while the others per-
form between the Control and Remote site.
The internal clock is adjusted to the hour (xx:00:00)
when an externally connected switch is turned on, as
far as the clock deviates within 3 minutes before or
after the hour.
Current communication will be forcibly disconnected
when an externally connected switch is turned on.
The In-Communication Status Out will be active while
the unit on the site is in communication, not the unit on
the other site.
Parallel inputs and outputs are used between the
Control site and Remote site.
Parallel input information is reflected to parallel output
terminals on the other site, from a Control site to
Remote site or vice versa. For example, an electric
lamp can be turned on to illuminate the aiming zone of
the camera on the Remote site when the switch con-
nected to a parallel input is pressed on the Control site.

[To working personnel]
Prior to starting work, turn off the power supply and pull out the power plug out of the wall outlet.
Inform the user of the fact that more than 48 hours of charging is required for initial usage after the completion of con-
nections.
Operation of the clock used in this unit is sustained by backup operation of the built-in battery. When this unit is initially used,
continuous charging is needed for more than 48 hours so that the backup battery can be charged up. In the following cases,
the clock may become out of order:
• Lack of charging time
• A service interruption continued for a long time
• The POWER switch has been set at OFF for a long time, or the power plug has been left disconnected from the wall outlet.
If the clock becomes out of order, set the clock again.
The contents of the abbreviated directory and various setting data are stored in nonvolatile memory, and they cannot be lost
even if there is a service interruption.
