Step 6
Connect cables to the External I/O terminals, microphone/
line input connector, audio output connector and the
monitor out connector for adjustment. When connecting
these cables, hold the main body of the camera.

• External I/O terminals
Connect external devices.
When connecting an external device, remove 9 mm - 10 mm
{11/32 inches - 13/32 inches} of the outer jacket of the cable
and twist the cable core to prevent the short circuit first.
Specification of cable (wire): AWG #22 - #28,
Single core, twisted
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.
• Off, input, and output of the external I/O terminal 2
and 3 can be switched by configuring the setting.
Refer to the Operating Instructions on the provided
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”).
• Make sure external devices are installed so they do
not exceed the ratings.
• When using the EXT I/O terminals as the output termi
-
nals, ensure they do not cause signal collision with
external signals.

•
ALARM IN1/ DAY/NIGHT IN, 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
(maximum 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)
The default of EXT I/O terminals is “Off”.
• Microphone/line input cable
Connect a monaural mini plug (ø3.5 mm).
• Input impedance: Approx. 2 kΩ (unbalanced)
• Recommended cable length:
Less than 1 m {3.28 feet} (for microphone input)
Less than 10 m {32.8 feet} (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)
• Input level for the line input: Approx. –10 dBV
• Recommended plug: L type
• Audio output cable
Connect a stereo mini plug (ø3.5 mm) (Audio output is
monaural.). Use an external powered speaker.
• Output impedance: Approx. 600 Ω (unbalanced)
•
Recommended cable length: Less than 10 m {32.8 feet}
• Output level: –20 dBV
• Recommended plug: L type (A straight type plug must
be 40 mm {1-9/16 inches} or less.)
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.
• Make sure that the stereo mini plug is connected to
this cable. When a monaural mini plug is connected,
audio may not be heard.
When connecting a monaural speaker with amplifier,
use an optional conversion cable (mono-stereo).
• 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 adjustment monitor is provided only for checking
the adjustment of the angular field of view on the
video monitor when installing the camera or when
servicing. It is not intended to be used for recording
or monitoring.
• Depending on the Adjustment monitor, some charac
-
ters (such as the camera title) may not be displayed
on the screen.
