Panasonic WV-SC385 Installation Manual page 17

Specification of cable (wire): AWG #22 - #28, Single
core, twisted
EXT I/O terminal 2
(ALARM IN2/ALARM OUT)
EXT I/O terminal 1
(ALARM IN1)
4 3 2 1
EXT I/O terminal 3
(ALARM IN3/AUX OUT (Auxiliary output))
GND
Important:
• Do not connect 2 wires or more directly to a terminal.
When it is necessary to connect 2 or more wires, use
a splitter.
• Input and output of the external I/O terminal 2 and 3
can be switched by configuring the setting. Refer to
the Operating Instructions (included in the CD-ROM)
for further information about the EXT I/O terminal 2
and 3 (ALARM IN2, 3) settings ("Off", "Alarm input",
"Alarm output" or "AUX output").
• The default of EXT I/O terminals is "Off". When "Off" is
selected, it is possible to connect external devices as
well as the input setting.
• When using the EXT I/O terminals as the output termi-
nals, ensure they do not cause signal collision with
external signals.
<Ratings>
• ALARM IN1, ALARM IN2, ALARM IN3
Input specification: No-voltage make contact input
(4 V - 5 V DC, internally pulled up)
OFF: Open or 4 V - 5 V DC
ON: Make contact with GND (required drive current:
1 mA or more)
• ALARM OUT, AUX OUT
Output specification: Open collector output (maxi-
mum applied voltage: 20 V DC)
Open: 4 V - 5 V DC by internal pull-up
Close: Output voltage 1 V DC or less (maximum drive
current: 50 mA)
• Microphone/line input connector
Connect a monaural mini plug (ø3.5 mm).
• Input impedance: Approx. 2 kΩ
• Recommended cable length: 1 m {3.28 feet} or less
(for microphone input)
10 m {32.8 feet} or less (for line input)
• Recommended microphone: Plug-in power type
(option)
• Supply voltage: 2.5 V ±0.5 V
• Recommended sensitivity of microphone: –48 dB ±3
dB (0 dB=1 V/Pa,1 kHz)
• Recommended plug: L type
Strip range
Approx. 9 mm - 10 mm
{11/32 inches - 13/32 inches}
Important:
• Connect/disconnect the audio cables and turn on the
power of the camera after turning off the power of the
audio output devices. Otherwise, loud noise may be
heard from the speaker.
• Audio output connector
Connect a stereo mini plug (ø3.5 mm) (Audio output is
monaural.). Use an external powered speaker.
• Recommended cable length: 10 m {32.8 feet} or less
• Recommended plug: L type (A straight type plug must
be 40 mm {1-9/16 inches} or less.)
• Monitor out connector for adjustment
Connect a monaural mini plug (ø3.5 mm) (only for check-
ing if images are displayed on the monitor).
• Recommended plug: Straight type (Because of the
pin array difference, it is difficult to fit an L type plug
into this connector.)
Important:
• The monitor out connector for adjustment is provided
only for checking the adjustment of the angular field
of view on the video monitor when installing the cam-
era or when servicing.
It is not provided for recording/monitoring use.
• Black bands may appear at the top and bottom or
right and left of the screen. (That does not affect the
adjustment because the angular field of view is not
changed.)
Step 6
Mount the camera onto the camera mount bracket
(accessory). Fit the lock plate of the camera onto the
guide part of the camera mount bracket, and rotate the
camera clockwise after inserting the camera while putting
the center of the camera (screw hole for a tripod) onto the
center of the camera mount bracket.
